Recommended starting dose of captopril is 25 mg twice  day to be taken one hour before meals. A few precautions have to be taken with this medication:1. Measure your BP at least twice a day. It may cause hypotension on beginning treatment.2. Watch out for dry cough or metallic taste.3. Watch out for any swelling of lips, mouth or feet.If you have any of above problems stop medication immediately and rush to a doctor.Consult your doctor as soon as you get time and get your medication reviewed with him and also discuss alternative medications. </s>
