Frequently Asked Questions (FAQs)

^

Q: What should I inform my healthcare expert before I start treatment with Telmisartan?

A: You must give an account of your past and present diseases, especially diabetes, and all the ongoing medications, supplements and herbal medicines that you are taking. If you take anti-diabetic medication or insulin, track your blood sugar carefully while taking Losartan, particularly during the first month of its use. The combination of anti-diabetic medicines when on Telmisartan, may cause significant changes in your blood sugar levels owing to drug interactions. Aspirin and painkillers also diminish the positive effect on blood pressure of Losartan. Hence, sharing complete history is of utmost importance.
