What Are the Most Common Side Effects of Amlodipine? 12 Things to Watch For
Amlodipine is a commonly prescribed medication used to treat high blood pressure (hypertension) and chest pain (angina). It belongs to a class of drugs called calcium channel blockers, which work by relaxing blood vessels so blood can flow more easily. While many people take amlodipine without significant problems, it’s important to be aware of its potential side effects.
Here are 12 side effects to watch for:
- Swelling of the feet or ankles (edema)
This is the most common side effect and may become more noticeable after standing or sitting for long periods. - Headache
Some people experience mild headaches, especially when starting the medication. - Dizziness or lightheadedness
Amlodipine can lower blood pressure, which may cause dizziness, particularly when standing up quickly. - Flushing
Warmth or redness of the face and neck can occur as blood vessels widen. - Fatigue
Feeling unusually tired or lacking energy is reported by some people. - Heart palpitations
You may notice your heart beating faster or more forcefully, especially early in treatment. - Nausea
Mild stomach upset or nausea may occur but often improves over time. - Abdominal pain
Some people experience stomach discomfort or cramping. - Sleepiness
Drowsiness can occur, although it is generally mild. - Skin rash or itching
Allergic skin reactions are uncommon but possible. Contact your healthcare provider if a rash develops. - Gum overgrowth (gingival hyperplasia)
Rarely, long-term use may cause the gums to enlarge. Good oral hygiene and regular dental care can help reduce this risk. - Low blood pressure (hypotension)
In some cases, blood pressure may become too low, leading to fainting or severe dizziness.
When to Seek Medical Attention
Contact your healthcare provider promptly if you experience:
- Severe or worsening swelling.
- Chest pain that is new or gets worse.
- Fainting or severe dizziness.
- Difficulty breathing.
- Swelling of the face, lips, tongue, or throat, or a severe rash, which could indicate a serious allergic reaction.
