When should I not use this medicine?
Do not take this medicine if you ever had an allergic reaction (rashes, breathlessness, swollen eyes) to Sirolimus and similar medicines such as everolimus, pimecrolimus, tacrolimus, temsirolimus or zotarolimus.
What should I take note of while taking this medicine?
Alert your doctor if you have the following conditions:
  • hyperlipidaemia (excessive amount of fats in the blood)
  • high blood pressure
  • heart disease
  • lung disease 
  • liver disease
as Sirolimus may not be suitable for you.

Let your doctor know if you are pregnant or breastfeeding.

Apply sunscreen or wear protective clothing when going outdoors. Avoid direct or prolonged exposure to the sun and ultraviolet (UV) lamps like tanning beds.

Keep your appointments with your doctor. For as long as you are taking Sirolimus, you may need to have regular blood tests to check your body’s response to the medicine and the health of your kidney and liver. Your doctor will advise you how often you need to have them.
What side effects could I experience?
This medicine may cause any of the following side effects: headache, diarrhoea, nausea, constipation, stomach pain, sore throat, high blood pressure, chest pain, fast heartbeat, skin rash, acne, and joint pain.

This medicine will cause the level of your red blood cells, white blood cells and platelets to drop.

Red blood cells carry oxygen around your body. A fall in the level of red blood cells may make you feel tired and worn out.

White blood cells help your body to fight infections. A fall in the level of your white blood cells may put you at higher risk for infections, such as coughs, colds and flu, which may lead to more serious infections. Avoid crowded places and people who are sick. Alert your doctor if you have a fever, or a cough or flu that does not go away.

Platelets help your blood to clot when there is a cut in the skin. A fall in the level of your platelets may put you at risk of bleeding more than usual. Do not take part in activities where you may fall or get injured, such as contact sports. Alert your doctor if you get any unusual bruising (large bruises or several bruises, especially if the bruises appeared on their own) or bleeding that takes a long time to stop (for example, too much bleeding when you floss or brush your teeth).

Some side effects may need immediate medical help. Alert your doctor quickly if you experience difficulty in breathing, swelling of the face, mouth, lips, tongue or throat.

Inform your doctor if any of these side effects do not go away or are severe, or if you experience other side effects.
Can I take this with other medicines?
Inform your doctor and pharmacist if you are taking any of these medicines:
  • medicines for fungal infection e.g. ketoconazole, fluconazole, itraconazole
  • medicines to treat TB (an infection known as tuberculosis) e.g. rifampicin
  • certain antibiotics e.g. clarithromycin
