Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

What should I do if I forget to take my daily dose?

Take the missed pill as soon as you remember. If it is almost time for your next scheduled dose, skip the missed one and continue with your regular schedule. Never take two doses at once to make up for a forgotten pill.

Can I drink alcohol while taking candesartan and hydrochlorothiazide?

Drinking alcohol can lower your blood pressure further and increase dizziness or drowsiness. It is best to limit or completely avoid alcoholic beverages while taking this medicine. Talk to your doctor about what is safe for you.

Why does this medicine make me urinate more often?

One of the active ingredients, hydrochlorothiazide, is a diuretic or water pill. It signals your kidneys to remove extra salt and water from your body, which helps lower your blood pressure.

Is it safe to take this medicine during pregnancy?

No, taking this medicine during pregnancy, especially in the second and third trimesters, can cause serious injury or harm to an unborn baby. Contact your doctor right away if you become pregnant while taking these pills.

Can I use salt substitutes while on this medicine?

You should avoid salt substitutes unless your doctor specifically recommends them. Many salt substitutes contain high levels of potassium, which can interact dangerously with this medicine.
