Anti-rejection medicines after liver transplantation: a practical guide
Content date: 13 November 2026
Anti-rejection medicines protect your transplanted liver by reducing the immune response against it. They are essential to transplant success and usually continue lifelong, even when blood tests are normal.
Your next step
Keep your transplant prescription, team contact number and missed-dose plan accessible. Confirm your next blood test and refill.
Get urgent help: Seek emergency care for breathing difficulty, confusion or fainting, major bleeding, or rapid deterioration with fever. Do not wait for a clinic or message reply.
Why do I need more than one medicine?
- Combining medicines with different actions provides protection while reducing high-dose side effects. Treatment differs between patients and changes with time after transplantation, kidney function, infections and adverse effects. Later dose reductions do not remove the need for follow-up.
- Options include tacrolimus or ciclosporin, mycophenolate and corticosteroids. Everolimus or azathioprine may be selected in particular circumstances. This is not a list everyone should take together: follow your transplant team’s prescription.
What monitoring should I expect?
- Tacrolimus and ciclosporin may affect kidney function and blood pressure; tacrolimus may raise glucose or cause tremor. Mycophenolate can cause diarrhoea or low blood-cell counts; azathioprine also requires blood counts and liver tests. Your team assesses symptoms and adjusts treatment safely.
- Selected patients taking everolimus need monitoring of its level, blood lipids, urine protein and wound healing; mouth ulcers can occur. Steroids can affect glucose, blood pressure and bones. Separate cards cover steroids, azathioprine and the main transplant medicines.
A daily routine that protects your transplant
- Keep an updated list of brands, strengths, doses and times; use reminders. Arrange refills early and plan travel or fasting with your team. Do not change products, manufacturers or dose frequency yourself, or stop treatment because you feel well.
- For a missed or vomited dose, check product instructions and contact the team if uncertain. Never automatically double or repeat it. Vomiting or diarrhoea may prevent you retaining medicines or change drug levels, so contact the team that day.
Blood-test days and new medicines
- Some medicines need their level checked immediately before the next dose. Confirm which medicine and timing; bring the dose to take after sampling as instructed. Do not withhold all morning medicines or delay them all day. Rejection may cause no symptoms, so feeling well does not replace testing.
- Tell every clinician and pharmacist about your transplant. Check new medicines and supplements with the transplant team. Avoid grapefruit with medicines it interacts with, and herbs without review; these can alter treatment levels. Never borrow medicines or copy another patient’s dose.
- Paxlovid for COVID-19 needs transplant-team review before use because of important interactions with some anti-rejection medicines.
Prevention and pregnancy
- Review vaccinations, food safety and sun protection with the team. Do not receive live vaccines without their approval. Some infection-prevention medicines are temporary, whereas anti-rejection treatment usually continues long term; keep these plans separate.
- Discuss pregnancy, fatherhood and breastfeeding in advance. Mycophenolate particularly can harm an unborn baby and requires specialist planning. If pregnancy is possible, contact the transplant team immediately without stopping immunosuppression yourself.
When to get help
Seek emergency care for breathing difficulty, confusion or fainting, major bleeding, or rapid deterioration with fever. Do not wait for a clinic or message reply.
Contact the transplant team the same day for fever, new jaundice, vomiting or diarrhoea, reduced urine, missed doses with an unclear plan, or a supply running out.
