Sirolimus
Sirolimus is an immunosuppressant used within selected specialist regimens, most often in transplant care. It requires coordinated monitoring and must not be substituted or interrupted independently.
Key points
- Sirolimus blood levels can change with interacting medicines and foods, affecting both toxicity and transplant protection.
- Treatment can increase infection risk and affect blood counts, lipids, kidney-related parameters, wound healing and lung function.
- Product changes or missed treatment should be discussed promptly with the transplant or specialist team.
Listings are for comparison only; suitability and supply depend on the specialist regimen, prescription, monitoring results and pharmacy checks.
What sirolimus is used for
Sirolimus may be used with other medicines to prevent transplant rejection. Other specialist uses are product- and condition-specific and should not be inferred from a listing.
How it works
Sirolimus inhibits mTOR signalling, reducing immune-cell activation and proliferation. This can protect a transplant but also affects infection response, healing and blood-cell production.
Important safety checks
Monitoring may include sirolimus levels, blood counts, kidney and liver parameters, urine protein and blood lipids. The team should review infections, vaccines, planned surgery, lung symptoms and all medicines and supplements. Grapefruit can alter exposure.
When to seek urgent care
Seek urgent help for severe breathlessness, chest pain, coughing blood, facial swelling or breathing difficulty. Contact the specialist team urgently for fever, worsening cough, a painful or non-healing wound, unusual bleeding, very little urine or severe mouth ulcers that prevent drinking.
