Myotec, a brand name for a formulation containing essential Mycophenolic acid, is widely used for various health benefits. This guide provides comprehensive information on the uses, dosage, side effects, and mechanism of action of Myotec, as well as insights into how long it takes to work. Understanding these aspects can help you make informed decisions about its use and effectiveness.

Mycophenolic Acid

Myotec is an active metabolite of the immunosuppressant mycophenolate mofetil, used to treat autoimmune diseases such as lupus and rheumatoid arthritis.

Uses For

Myotec is approved to:

  • Treat transplant rejection in adults and in children ages 2 years and older.
  • Prevent the recurrence of kidney allograft rejection in adults.

Mechanism of Action

Myotec works by blocking an enzyme that is necessary for the body’s defense reaction to foreign substances. By blocking this enzyme, mycophenolic acid reduces the body’s ability to reject an organ transplant.

How Long Does it Take to Work

Myotec can take several weeks to produce therapeutic benefits. However, if combined with other immunosuppressants, the onset of action of mycophenolic acid may be reduced.


Myotec is rapidly and completely absorbed after an oral dose. It is also well-absorbed following an intramuscular (IM) injection. The peak plasma concentrations of mycophenolic acid occur about two hours after ingestion.

Route of Elimination

Myotec is readily eliminated by the kidney and has a half-life of about one hour.


Myotec is typically administered in an oral form or by intramuscular injection. The usual dose is two to three times daily, depending on the patient’s condition. The precise dosage and duration of treatment should be determined by a health care professional.


Myotec is usually taken orally with food, or as an intramuscular injection. It is important to take mycophenolic acid at the same time each day to ensure consistent therapeutic effects.


Myotec can cause side effects including nausea, vomiting, abdominal pain, diarrhea, headache, dizziness, and fatigue.


Myotec can build up in the bloodstream over time if too much is taken. This can lead to serious side effects and can even be fatal in some cases.


It is important to closely follow the dosing instructions from your healthcare practitioner. Patients taking mycophenolic acid should also be aware of any potential drug-drug interactions, as mycophenolic acid may interact with other medications.
