Contraindications for Clotrimazole Use

A contraindication is a specific situation or condition where a medication should not be used because it may cause harm. In the case of Clotrimazole, certain conditions may make it unsafe for you to use this medication. Below are the main contraindications for Clotrimazole:

Clotrimazole can interact with other medications, potentially affecting their efficacy or increasing the risk of side effects. Below are some medications that may interact with Clotrimazole:

Warfarin (Coumadin): Clotrimazole may enhance the effects of Warfarin, a blood thinner, which can increase the risk of bleeding.

Sirolimus (Rapamune): Clotrimazole may raise the levels of Sirolimus, an immunosuppressant, potentially leading to toxicity.

Tacrolimus (Prograf): Similar to Sirolimus, Clotrimazole may elevate Tacrolimus levels, increasing the risk of side effects such as kidney damage or high blood pressure.
