More Detail on Telmisartan/Hydrochlorothiazide Interactions
Diuretics
When taking
telmisartan/
hydrochlorothiazide with a diuretic, your
blood pressure may decrease too much. This is more likely to occur when telmisartan/hydrochlorothiazide is first started. In order to prevent this interaction from occurring, your healthcare provider may change the dose of either medicine, start you on a lower dose of telmisartan/hydrochlorothiazide, and/or monitor you more closely.
Potassium Supplements or Salt Substitutes With Potassium
If you are taking telmisartan/hydrochlorothiazide along with a potassium supplement or a salt substitute with potassium, the levels of potassium in your blood may become too high. This can cause serious problems. Ask your healthcare provider about using potassium and telmisartan/hydrochlorothiazide together.
Potassium-Sparing Diuretics
If you are taking both telmisartan/hydrochlorothiazide and a potassium-sparing diuretic, your body may metabolize these drugs differently than intended and/or increase the levels of potassium in your blood. Your healthcare provider may choose to monitor your progress closely if this is the case.
Digoxin
Taking digoxin and telmisartan/hydrochlorothiazide together may increase the levels of digoxin in the blood. When starting or stopping digoxin or changing the digoxin dosage, your healthcare provider may choose to monitor you more closely and/or make necessary dosing adjustments.
Warfarin
If you are taking
warfarin with telmisartan/hydrochlorothiazide, your body may metabolize the warfarin differently than intended. Your healthcare provider may choose to monitor your INR and prothrombin time more frequently and adjust your warfarin dose accordingly. INR and prothrombin time are tests used to measure how well your blood is clotting.
