Uses for methyldopa
Methyldopa belongs to the general class of medicines called antihypertensives. It is used to treat high blood pressure (hypertension).
High blood pressure adds to the work load of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Methyldopa works by controlling impulses along certain nerve pathways. As a result, it relaxes blood vessels so that blood passes through them more easily. This helps to lower blood pressure.
Methyldopa is available only with your doctor's prescription.
Before using methyldopa
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For methyldopa, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to methyldopa or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Although there is no specific information comparing use of methyldopa in children with use in other age groups, methyldopa is not expected to cause different side effects or problems in children than it does in adults.
Geriatric
Dizziness or lightheadedness and drowsiness may be more likely to occur in the elderly, who are more sensitive to the effects of methyldopa.
Breastfeeding
Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
