CellCept® (mycophenolate mofetil) is an immunosuppressant designed to prevent organ rejection in people with kidney, heart, or liver transplants. It works by reducing immune activity that attacks transplanted organs. By targeted suppression of the immune system, Cellcept can help protect the transplanted organ from rejection.
CellCept is administered orally as tablets, capsules, or liquid, and is also available for intravenous infusion in adults. Dosing varies by type of transplant; use in combination with ciclosporin and corticosteroids per USPI. For some patients, financial assistance may be available.
Common side effects of Cellcept include diarrhea, low white and red blood cell counts, infections, and blood pressure problems. Some individuals may also experience swelling of the lower legs, ankles, and feet. Cellcept can cause serious side effects, including risk of miscarriage, birth defects, and severe allergic reactions. Regular blood tests are required to monitor blood cell counts. Immediate medical attention is necessary if you experience trouble breathing, fainting, or swelling of the face or throat. Do not take CELLCEPT if you have a history of allergic reactions to mycophenolate mofetil or any of the ingredients in CELLCEPT.

IMPORTANT SAFETY INFORMATION & INDICATION

Back to Top

[H2] INDICATION
[H2]
WHAT IS CELLCEPT?
CellCept® (mycophenolate mofetil) is a prescription medicine to prevent rejection (antirejection medicine) in people who have received a kidney, heart or liver transplant. Rejection is when the body’s immune system perceives the new organ as a “foreign” threat and attacks it.
CellCept is used with other medicines containing cyclosporine and corticosteroids.

[H2] IMPORTANT SAFETY INFORMATION
[H2]
WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT CELLCEPT?
[H2] CELLCEPT CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:
Increased risk of loss of a pregnancy (miscarriage) and higher risk of birth defects. Females who take CellCept during pregnancy have a higher risk of miscarriage during the first 3 months (first trimester), and a higher risk that their baby will be born with birth defects.
If you are a female who can become pregnant, your doctor must talk with you about acceptable birth control methods (contraceptive counseling) to use while taking CellCept. You should have 1 pregnancy test immediately before starting CellCept and another pregnancy test 8 to 10 days later. Pregnancy tests should be repeated during routine follow-up visits with your doctor. Talk to your doctor about the results of all of your pregnancy tests. You must use acceptable birth control during your entire CellCept treatment and for 6 weeks after stopping CellCept, unless at any time you choose to avoid sexual intercourse (abstinence) with a man completely. CellCept decreases blood levels of the hormones in birth control pills that you take by mouth. Birth control pills may not work as well while you take CellCept, and you could become pregnant. If you take birth control pills while using CellCept you must also use another form of birth control. Talk to your doctor about other birth control methods that you can use while taking CellCept.
If you are a sexually active male whose female partner can become pregnant while you are taking CellCept, use effective contraception during treatment and for at least 90 days after stopping CellCept.
If you plan to become pregnant, talk with your doctor. Your doctor will decide if other medicines to prevent rejection may be right for you.
If you become pregnant while taking CellCept, do not stop taking CellCept. Call your doctor right away. You and your doctor may decide that other medicines to prevent rejection may be right for you. You and your doctor should report your pregnancy to the Mycophenolate Pregnancy Registry either:
by phone at 1-800-617-8191 or
by visiting the Risk Evaluation and Mitigation Strategy (REMS) website at www.mycophenolateREMS.com
The purpose of this registry is to gather information about the health of you and your baby.
Increased risk of getting certain cancers. People who take CellCept have a higher risk of getting lymphoma, and other cancers, especially skin cancer. Tell your doctor if you have:
unexplained fever, prolonged tiredness, weight loss or lymph node swelling
a brown or black skin lesion with uneven borders, or one part of the lesion does not look like the other
a change in the size and color of a mole
a new skin lesion or bump
any other changes to your health
Increased risk of getting serious infections. CellCept weakens the body’s immune system and affects your ability to fight infections. Serious infections can happen with CellCept and can lead to hospitalizations and death. These serious infections can include:
Viral infections. Certain viruses can live in your body and cause active infections when your immune system is weak. Viral infections that can happen with CellCept include:
shingles, other herpes infections, and cytomegalovirus (CMV). CMV can cause serious tissue and blood infections
BK virus. BK virus can affect how your kidney works and cause your transplanted kidney to fail
hepatitis B and C viruses. Hepatitis viruses can affect how your liver works. Talk to your doctor about how hepatitis viruses may affect you
COVID-19
A brain infection called Progressive Multifocal Leukoencephalopathy (PML). In some patients, CellCept may cause an infection of the brain that may cause death. You are at risk for this brain infection because you have a weakened immune system. Call your doctor right away if you have any of the following symptoms:
weakness on one side of the body
you do not care about things that you usually care about (apathy)
you are confused or have problems thinking
you can not control your muscles
Fungal infections. Yeasts and other types of fungal infections can happen with CellCept and can cause serious tissue and blood infections (See “What are the possible side effects of CellCept?”).
Call your doctor right away if you have any of the following signs and symptoms of infection:
temperature of 100.5°F or greater
cold symptoms, such as a runny nose or sore throat
flu symptoms, such as an upset stomach, stomach pain, vomiting or diarrhea
earache or headache
pain during urination
white patches in the mouth or throat
unexpected bruising or bleeding
cuts, scrapes or incisions that are red, warm and oozing pus
See “What are the possible side effects of CellCept?” for information about other serious side effects.

[H2] WHO SHOULD NOT TAKE CELLCEPT
Do not take CellCept if you have a history of allergic reactions to mycophenolate mofetil or any of the ingredients in CellCept.

[H2] WHAT SHOULD I TELL MY DOCTOR BEFORE TAKING CELLCEPT?

[H2]
WHAT ARE THE POSSIBLE SIDE EFFECTS OF CELLCEPT?
CELLCEPT CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:

See “What is the most important information I should know about CellCept?”
Low blood cell counts. People taking high doses of CellCept each day may have a decrease in blood counts, including:
white blood cells, especially neutrophils. Neutrophils fight against bacterial infections. You have a higher chance of getting an infection when your white blood cell count is low. This is most common from 1 month to 6 months after your transplant
red blood cells. Red blood cells carry oxygen to your body tissues. You have a higher chance of getting severe anemia when your red blood cell count is low
platelets. Platelets help with blood clotting
Your doctor will do blood tests before you start taking CellCept and during treatment with CellCept to check your blood cell counts. Tell your doctor right away if you have any signs of infection (see “What is the most important information I should know about CellCept?”), including any unexpected bruising or bleeding. Also, tell your doctor if you have unusual tiredness, lack of energy, dizziness or fainting.
Stomach problems. Stomach problems including intestinal bleeding, a tear in your intestinal wall (perforation) or stomach ulcers can happen in people who take CellCept. Bleeding can be severe and you may have to be hospitalized for treatment. Call your doctor right away if you have sudden or severe stomach-area pain or stomach-area pain that does not go away, or if you have diarrhea.
Inflammatory reactions. Some people taking CellCept may have an inflammatory reaction with fever, joint stiffness, joint pain, and muscle pain. Some of these reactions may require hospitalization. This reaction could happen within weeks to months after your treatment with CellCept starts or if your dose is increased. Call your doctor right away if you experience these symptoms.
Allergic (hypersensitivity) reactions. Allergic reactions including severe allergic reaction called anaphylaxis, can happen after taking CellCept. Stop taking CellCept and get emergency medical help right away if you have any of the following symptoms on an allergic reaction:
swelling of the face, lips, tongue, or throat
rash, hives, or itching
fainting, dizziness, feeling lightheaded
trouble breathing or swallowing
fast heartbeat
chest pain

The most common side effects of CellCept include:
diarrhea
blood problems including low white and red blood cell counts
infections
blood pressure problems
fast heart beat
swelling of the lower legs, ankles and feet

IMPORTANT SAFETY INFORMATION & INDICATION

Back to Top

[H2] INDICATION
[H2]
WHAT IS CELLCEPT?
CellCept® (mycophenolate mofetil) is a prescription medicine to prevent rejection (antirejection medicine) in people who have received a kidney, heart or liver transplant. Rejection is when the body’s immune system perceives the new organ as a “foreign” threat and attacks it.
CellCept is used with other medicines containing cyclosporine and corticosteroids.

[H2] IMPORTANT SAFETY INFORMATION
[H2]
WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT CELLCEPT?
[H2] CELLCEPT CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:
Increased risk of loss of a pregnancy (miscarriage) and higher risk of birth defects. Females who take CellCept during pregnancy have a higher risk of miscarriage during the first 3 months (first trimester), and a higher risk that their baby will be born with birth defects.
If you are a female who can become pregnant, your doctor must talk with you about acceptable birth control methods (contraceptive counseling) to use while taking CellCept. You should have 1 pregnancy test immediately before starting CellCept and another pregnancy test 8 to 10 days later. Pregnancy tests should be repeated during routine follow-up visits with your doctor. Talk to your doctor about the results of all of your pregnancy tests. You must use acceptable birth control during your entire CellCept treatment and for 6 weeks after stopping CellCept, unless at any time you choose to avoid sexual intercourse (abstinence) with a man completely. CellCept decreases blood levels of the hormones in birth control pills that you take by mouth. Birth control pills may not work as well while you take CellCept, and you could become pregnant. If you take birth control pills while using CellCept you must also use another form of birth control. Talk to your doctor about other birth control methods that you can use while taking CellCept.
If you are a sexually active male whose female partner can become pregnant while you are taking CellCept, use effective contraception during treatment and for at least 90 days after stopping CellCept.
If you plan to become pregnant, talk with your doctor. Your doctor will decide if other medicines to prevent rejection may be right for you.
If you become pregnant while taking CellCept, do not stop taking CellCept. Call your doctor right away. You and your doctor may decide that other medicines to prevent rejection may be right for you. You and your doctor should report your pregnancy to the Mycophenolate Pregnancy Registry either:
by phone at 1-800-617-8191 or
by visiting the Risk Evaluation and Mitigation Strategy (REMS) website at www.mycophenolateREMS.com
The purpose of this registry is to gather information about the health of you and your baby.
Increased risk of getting certain cancers. People who take CellCept have a higher risk of getting lymphoma, and other cancers, especially skin cancer. Tell your doctor if you have:
unexplained fever, prolonged tiredness, weight loss or lymph node swelling
a brown or black skin lesion with uneven borders, or one part of the lesion does not look like the other
a change in the size and color of a mole
a new skin lesion or bump
any other changes to your health
Increased risk of getting serious infections. CellCept weakens the body’s immune system and affects your ability to fight infections. Serious infections can happen with CellCept and can lead to hospitalizations and death. These serious infections can include:
Viral infections. Certain viruses can live in your body and cause active infections when your immune system is weak. Viral infections that can happen with CellCept include:
shingles, other herpes infections, and cytomegalovirus (CMV). CMV can cause serious tissue and blood infections
BK virus. BK virus can affect how your kidney works and cause your transplanted kidney to fail
hepatitis B and C viruses. Hepatitis viruses can affect how your liver works. Talk to your doctor about how hepatitis viruses may affect you
COVID-19
A brain infection called Progressive Multifocal Leukoencephalopathy (PML). In some patients, CellCept may cause an infection of the brain that may cause death. You are at risk for this brain infection because you have a weakened immune system. Call your doctor right away if you have any of the following symptoms:
weakness on one side of the body
you do not care about things that you usually care about (apathy)
you are confused or have problems thinking
you can not control your muscles
Fungal infections. Yeasts and other types of fungal infections can happen with CellCept and can cause serious tissue and blood infections (See “What are the possible side effects of CellCept?”).
Call your doctor right away if you have any of the following signs and symptoms of infection:
temperature of 100.5°F or greater
cold symptoms, such as a runny nose or sore throat
flu symptoms, such as an upset stomach, stomach pain, vomiting or diarrhea
earache or headache
pain during urination
white patches in the mouth or throat
unexpected bruising or bleeding
cuts, scrapes or incisions that are red, warm and oozing pus
See “What are the possible side effects of CellCept?” for information about other serious side effects.

[H2] WHO SHOULD NOT TAKE CELLCEPT
Do not take CellCept if you have a history of allergic reactions to mycophenolate mofetil or any of the ingredients in CellCept.

[H2] WHAT SHOULD I TELL MY DOCTOR BEFORE TAKING CELLCEPT?

Know the medicines you take. Keep a list of them to show to your doctor or nurse and pharmacist when you get a new medicine. Do not take any new medicine without talking with your doctor.

[H2]
HOW SHOULD I TAKE CELLCEPT?

Take CellCept exactly as prescribed.
Do not stop taking CellCept or change the dose unless your doctor tells you to.
If you miss a dose of CellCept, or you are not sure when you took your last dose, take your prescribed dose of CellCept as soon as you remember. If your next dose is less than 2 hours away, skip the missed dose and take your next dose at your normal scheduled time. Do not take 2 doses at the same time. Call your doctor if you are not sure what to do.
Take CellCept capsules, tablets and oral suspension on an empty stomach, unless your doctor tells you otherwise. Do not crush CellCept tablets.

If you take too much CellCept, call your doctor or the poison control center right away.

[H2]
WHAT SHOULD I AVOID WHILE TAKING CELLCEPT?

Avoid becoming pregnant. See “What is the most important information I should know about CellCept?”
Limit the amount of time you spend in sunlight. Avoid using tanning beds or sunlamps. People who take CellCept have a higher risk of getting skin cancer. (See “What is the most important information I should know about CellCept?”) Wear protective clothing when you are in the sun and use a broad-spectrum sunscreen with a high protection factor. This is especially important if your skin is very fair or if you have a family history of skin cancer.
You should not donate blood while taking CellCept and for at least 6 weeks after stopping CellCept.
You should not donate sperm while taking CellCept and for 90 days after stopping CellCept.
CellCept may influence your ability to drive and use machines (See “What are the possible side effects of CellCept?”). If you experience drowsiness, confusion, dizziness, tremor, or low blood pressure during treatment with CellCept, you should be cautious about driving or using heavy machines.

[H2]
WHAT ARE THE POSSIBLE SIDE EFFECTS OF CELLCEPT?
CELLCEPT CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:

See “What is the most important information I should know about CellCept?”
Low blood cell counts. People taking high doses of CellCept each day may have a decrease in blood counts, including:
white blood cells, especially neutrophils. Neutrophils fight against bacterial infections. You have a higher chance of getting an infection when your white blood cell count is low. This is most common from 1 month to 6 months after your transplant
red blood cells. Red blood cells carry oxygen to your body tissues. You have a higher chance of getting severe anemia when your red blood cell count is low
platelets. Platelets help with blood clotting
Your doctor will do blood tests before you start taking CellCept and during treatment with CellCept to check your blood cell counts. Tell your doctor right away if you have any signs of infection (see “What is the most important information I should know about CellCept?”), including any unexpected bruising or bleeding. Also, tell your doctor if you have unusual tiredness, lack of energy, dizziness or fainting.
Stomach problems. Stomach problems including intestinal bleeding, a tear in your intestinal wall (perforation) or stomach ulcers can happen in people who take CellCept. Bleeding can be severe and you may have to be hospitalized for treatment. Call your doctor right away if you have sudden or severe stomach-area pain or stomach-area pain that does not go away, or if you have diarrhea.
Inflammatory reactions. Some people taking CellCept may have an inflammatory reaction with fever, joint stiffness, joint pain, and muscle pain. Some of these reactions may require hospitalization. This reaction could happen within weeks to months after your treatment with CellCept starts or if your dose is increased. Call your doctor right away if you experience these symptoms.
Allergic (hypersensitivity) reactions. Allergic reactions including severe allergic reaction called anaphylaxis, can happen after taking CellCept. Stop taking CellCept and get emergency medical help right away if you have any of the following symptoms on an allergic reaction:
swelling of the face, lips, tongue, or throat
rash, hives, or itching
fainting, dizziness, feeling lightheaded
trouble breathing or swallowing
fast heartbeat
chest pain

The most common side effects of CellCept include:
diarrhea
blood problems including low white and red blood cell counts
infections
blood pressure problems
fast heart beat
swelling of the lower legs, ankles and feet
changes in laboratory blood levels, including high levels of blood sugar (hyperglycemia)
stomach problems including diarrhea, constipation, nausea and vomiting
rash
nervous system problems such as headache, dizziness and tremor
Side effects that can happen more often in children than in adults taking CellCept include:

[H1] Getting Brand-name CellCept
The first step toward getting brand-name CellCept is making sure your doctor prescribes it. If you have been prescribed CellCept, ask your doctor to verify that your prescription specifies that a generic should not be substituted.
It’s also important to recognize the differences between brand-name CellCept and the generic versions. That way you can check your medicine at the pharmacy and make sure you get what your doctor prescribed.
[H2]
Here’s how to identify brand-name CellCept:

[IMG: 250 mg capsule]

250 mg, blue-brown, 2-piece, hard gelatin capsules
Printed in black with “CellCept 250” on the blue cap and “Roche” on the brown body

[IMG: 500 mg capsule]

500 mg, lavender-colored, caplet-shaped, film-coated tablets
Printed in black with “CellCept 500” on one side and “Roche” on the other side

[IMG: 225 ml bottle]

White to off-white, mixed-fruit-flavor suspension
Supplied in a 225 mL bottle with a bottle adaptor and 2 oral dispensers
Not actual size and may not represent exact color. CellCept is also available in an intravenous form for use in hospitals.
[H2] Make sure you receive brand-name CellCept
It’s important to know that a pharmacist could switch your prescription to a generic. Here are some of the ways you can make sure you are receiving the brand-name medicine you have been prescribed:
Check your medicine before you leave the pharmacy
Know your health insurance. Your health insurance company may require a prior authorization for you to receive CellCept when a generic version is available. Check with your transplant team to determine if one is needed for your prescription
Talk to your pharmacist. If your doctor has indicated on your CellCept prescription that a generic version should not be substituted, let your pharmacist know. Encourage your pharmacist to call your doctor if there are any questions
Ask your transplant team to confirm if you have been prescribed brand-name CellCept

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

This is a low-BS, highly regulated pharmaceutical site that sacrifices user experience for mandatory safety disclosures. While technically repetitive and lacking external proof paths, its physical descriptions and financial transparency provide genuine substance for the patient.

Resolve the metadata error where a review_count of 1 is reported without visible user-generated content to eliminate trust theatre flags. Add a dedicated ‘Clinical Data’ section that links directly to peer-reviewed studies on PubMed and ClinicalTrials.gov results for mycophenolate mofetil. Consolidate repetitive safety blocks into an expandable footer or linked modal to improve the substance-to-repetition ratio on navigation-heavy pages. Explicitly cite the original FDA approval date and number to provide a primary proof path for the medication’s legitimacy.

The content perfectly aligns with the Medical Pharma and Biotech industry, specifically focusing on immunosuppressant therapy for transplant patients. All provided pages contain high-density regulatory and safety language typical of FDA-compliant pharmaceutical sites.

“The score of 18 is driven almost entirely by the verbatim repetition of the ISI across all pages and a trust theatre flag triggered by the discrepancy between review_count metadata and actual review content. These are minor procedural BS markers in an otherwise high-substance medical property.”
