How does this medication work? What will it do for me?

Felodipine belongs to a class of medications called calcium channel blockers. It may be used alone or with other medications to treat mild-to-moderate high blood pressure. It controls blood pressure by relaxing blood vessels and reducing the workload of the heart.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Congestive heart failure: The safety and efficacy of felodipine for people with heart failure have not been established. If you have congestive heart failure or are at risk of developing congestive heart failure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Dental hygiene: Because felodipine can cause swollen and tender gums, it is important to practice good dental hygiene by flossing, brushing, and visiting your dentist regularly. Talk to your doctor or dentist to learn more about how to take care of your mouth, gums, and teeth while taking this medication.

Grapefruit juice: Grapefruit juice can increase blood levels of felodipine. Avoid drinking grapefruit juice or eating grapefruit before or while you are taking felodipine.

Lactose intolerance: People with hereditary galactose intolerance should not take this medication.

Liver function:  Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Low blood pressure: Felodipine may cause a severe lowering of blood pressure when rising from a sitting or lying position, or a racing heart rate, especially during the first few weeks of treatment. If you feel dizzy or lightheaded or feel your pulse is racing, and this feeling does not go away after a few minutes, call your doctor. Because this medication can cause dizziness or lightheadedness, do not get up too quickly after you have been sitting or lying for prolonged periods. If you have heart disease (e.g., heart failure, heart attack) or are taking medications that lower blood pressure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. When felodipine is first prescribed or the dosage is increased, blood pressure should be closely monitored.

Pregnancy: Felodipine may cause harm to a developing baby if it is taken by the mother while pregnant. If you become pregnant while taking felodipine, contact your doctor immediately.

Breast-feeding: Felodipine should not be taken by women who are breast-feeding. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
