What is the most important information I should know about captopril (Capoten)?

Drinking alcohol can further lower your blood pressure and may increase certain side effects of captopril.

Do not use salt substitutes or potassium supplements while taking captopril, unless your doctor has told you to.

Conditions that may cause very low blood pressure include: vomiting, diarrhea, heavy sweating, heart disease, dialysis, a low salt diet, or taking diuretics (water pills).
