People who are taking or plan on taking candesartan should be aware of certain drug interactions with other medications, such as diuretics, potassium supplements, and lithium. These interactions might cause your blood pressure to decline too much or allow the levels of potassium in your body to become too high. Therefore, it is important to consult your pharmacist or healthcare provider about any candesartan drug interactions that may apply to you.
When taking candesartan with a diuretic, your blood pressure may decrease too much. This is more likely to occur when candesartan is first started. In order to decrease the chances of this interaction, your healthcare provider may change the dosages of either medicine, start you on a lower dose of candesartan, and/or monitor you more closely.
Potassium Supplements
If you are taking a potassium supplement and candesartan, 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 candesartan together.
