Interactions between your drugs

Moderate

losartan sirolimus

Applies to: losartan and Rapamune (sirolimus)

Using losartan together with sirolimus may increase the risk of angioedema, a condition associated with swelling of the face, eyes, lips, tongue, throat, and occasionally also the hands and feet. Although either medication alone can cause angioedema, research data suggest that the risk may be greater when they are combined. Angioedema can occur with the first dose of medication or after many doses. You should discontinue the medications and seek immediate medical attention if you develop symptoms of angioedema or have difficulty swallowing or breathing. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

If you are taking losartan you should avoid potassium-containing salt substitutes or over-the-counter potassium supplements without first talking to your doctor.

Call your doctor at once if you have any of these symptoms.

sirolimus food

Applies to: Rapamune (sirolimus)

Grapefruit and grapefruit juice may interact with sirolimus and could lead to potentially dangerous effects. Avoid eating grapefruit or drinking grapefruit juice while you are taking sirolimus. Also, you should preferably take sirolimus at least one hour before eating. If you do take it with food, you should take it each time with food to avoid changes in sirolimus levels. The oral liquid form of sirolimus must be mixed with water or orange juice only. Do not use grapefruit juice to mix this medication.
