Clinical monograph
How it works
It inhibits inosine monophosphate dehydrogenase, selectively suppressing T- and B-lymphocyte proliferation.
Prescribing in practice
- It is highly teratogenic and causes miscarriage — strict pregnancy prevention is required for anyone able to become pregnant, with relevant advice for men too (MHRA).
- Bone-marrow suppression and increased infection risk (including reactivation and, rarely, PML) occur; gastrointestinal effects are common.
- Avoid live vaccines; absorption is reduced by some antacids and by sevelamer.
Monitoring
Monitor full blood count regularly (especially early), review for infection, and confirm pregnancy-prevention measures.
Counselling the patient
- Use effective contraception and avoid pregnancy — it can seriously harm a baby.
- Report sore throat, fever, bruising or other signs of infection.
- Take it consistently and attend monitoring blood tests.
