Drug Interactions With Telmisartan: An Overview
Telmisartan (
Micardis®) can potentially interact with a number of other medicines. Some of these telmisartan interactions can include:
- Diuretics, such as torsemide (Demadex®), furosemide (Lasix®), hydrochlorothiazide, and others
- Potassium supplements
- Potassium-sparing diuretics, such as spironolactone (Aldactone®), triamterene (Dyrenium®), and amiloride (Midamor®), among others
- Digoxin (Digitek®, Lanoxicaps®, Lanoxin®)
- Warfarin (Coumadin®, Jantoven®).
Diuretics
When you are taking telmisartan with a diuretic, your
blood pressure may decrease too much. This is more likely to occur when telmisartan is first started. In order to decrease the chances of developing this telmisartan interaction, your healthcare provider may change the dosages of either medicine, start you on a lower dose of telmisartan, and/or monitor you more closely.
Potassium Supplements
If you are taking a potassium supplement with telmisartan, the levels of potassium in your blood may become too high. This can cause serious problems. For your particular situation, talk to your healthcare provider about using potassium and telmisartan together.
