Amlodipine — what it does, how to use it, and how to save

Amlodipine is a common blood pressure drug that relaxes blood vessels so your heart doesn’t have to work as hard. Doctors use it mainly for high blood pressure and some types of chest pain (angina). It’s popular because it usually works well and is available as a low-cost generic.

How amlodipine works and common doses

Amlodipine is a calcium channel blocker. That means it stops calcium from entering cells in your heart and blood vessel walls, which helps the vessels relax and lowers blood pressure. Most adults start at 5 mg once daily. If blood pressure isn’t controlled, doctors often increase to 10 mg once daily. For older adults or people who are sensitive to medication, a 2.5 mg start may be used.

Take it the same time each day, with or without food. Don’t double up if you miss a dose; take the next dose at the usual time or ask your doctor.

Side effects, interactions and practical monitoring

Common side effects are swelling of the ankles (peripheral edema), flushing, dizziness, and headache. Most people tolerate it, but swelling can be bothersome. Serious problems are rare but include very low blood pressure or worsening chest pain—call your doctor if you have sudden severe symptoms.

Amlodipine can interact with other blood pressure drugs and with strong CYP3A4 inhibitors (drugs that raise amlodipine levels). Grapefruit juice may increase levels too—avoid large amounts. If you’re on multiple heart medicines, tell your doctor and pharmacist so they can check for interactions.

Check your blood pressure at home and keep a log. New or increasing swelling, lightheadedness, or fast heartbeat should be reported. If you’re pregnant, breastfeeding, or planning pregnancy, talk to your clinician before taking amlodipine.

Want to switch or stop? Don’t stop suddenly. Stopping may cause blood pressure to rise. If you and your clinician decide to change therapy, they’ll suggest a plan to taper or switch safely.

Money-saving tips: always ask for the generic (amlodipine besylate). Compare prices between local pharmacies, big chains, and reputable online options. Buying a 90-day supply often lowers the per-pill cost. Look for pharmacy discount cards, manufacturer programs, or bulk-price sites. If you have a chronic condition, mail-order pharmacies can cut costs and deliver to your door.
