Important Precautions

Tell your health-care practitioner if you are sensitive or allergic to captopril or to any other drugs.
Rarely, captopril causes very low blood pressure. It may also cause dizziness or fainting. Until you know how you respond to the drug, do not drive or operate hazardous equipment.
Captopril may cause a reduction in kidney function, especially if you have heart failure. Your health-care practitioner may need to adjust your dosage if you have kidney problems.
Captopril may increase your risk of getting an infection. Your health-care practitioner should periodically check your blood count.
If you are taking captopril for your heart, do not increase physical activity too quickly. Discuss your exercise program with your health-care practitioner.
If you develop swelling of your tongue, throat, face, arms, or legs while taking captopril, stop taking the drug and contact your health-care practitioner immediately.

Pregnant Women

Captopril can cause birth defects or death to a developing fetus, especially during the second and third trimesters of pregnancy. If you are pregnant or plan to become pregnant, talk to your health-care practitioner about the potential risks to your unborn child.

Small amounts of captopril pass into breast milk. If you are breastfeeding, your health-care practitioner may advise you to stop while you are under treatment.

Seniors

Side effects are more likely to occur and to be more severe among older adults.
