Uses for rauwolfia alkaloid

Rauwolfia alkaloids belong to the general class of medicines called antihypertensives. They are used to treat high blood pressure (hypertension).

High blood pressure adds to the workload 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.

Rauwolfia alkaloids work by controlling nerve impulses along certain nerve pathways. As a result, they act on the heart and blood vessels to lower blood pressure.

Rauwolfia alkaloids may also be used to treat other conditions as determined by your doctor.

These medicines are available only with your doctor's prescription.

Before using rauwolfia alkaloid

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group 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 rauwolfia alkaloids in children with use in other age groups, rauwolfia alkaloids are not expected to cause different side effects or problems in children than they do in adults.

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of rauwolfia alkaloids in the elderly with use in other age groups, dizziness or drowsiness may be more likely to occur in the elderly, who are more sensitive to the effects of rauwolfia alkaloids.

Pregnancy

Rauwolfia alkaloids have not been studied in pregnant women. However, too much use of rauwolfia alkaloids during pregnancy may cause unwanted effects (difficult breathing, low temperature, loss of appetite) in the baby. In rats, use of rauwolfia alkaloids during pregnancy causes birth defects and in guinea pigs decreases newborn survival rates. Before taking rauwolfia alkaloid, make sure your doctor knows if you are pregnant or if you may become pregnant.

Breastfeeding

Rauwolfia alkaloids pass into breast milk and may cause unwanted effects (difficult breathing, low temperature, loss of appetite) in infants of mothers taking large doses of rauwolfia alkaloid. Be sure you have discussed this with your doctor before taking rauwolfia alkaloid.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking any of these medicines, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necess...
