12 Amlodipine Side Effects You Should Know About

Amlodipine is a commonly prescribed medication used to treat high blood pressure (hypertension) and some types of chest pain (angina). It works by relaxing blood vessels, allowing blood to flow more easily and reducing the workload on the heart.

Most people tolerate amlodipine well, but like all medicines, it can cause side effects. Some are mild and temporary, while others should be discussed with a healthcare professional.

1. Swollen Ankles or Feet (Oedema)

This is one of the most common side effects.

You may notice:

• Puffy ankles
• Swelling around the feet
• Tight shoes or socks leaving marks

It happens because blood vessels widen, which can allow fluid to collect in the lower legs.

2. Dizziness or Light-Headedness

Because amlodipine lowers blood pressure, some people may feel:

• Dizzy when standing up
• Light-headed
• Unsteady

This is more likely when first starting treatment or after a dose increase.

3. Headache

Some people experience headaches, especially early in treatment. These often improve as the body adjusts.

4. Flushing or Feeling Hot

Widening of blood vessels can cause:

• Warmth in the face
• Redness
• A sudden feeling of heat

5. Tiredness or Fatigue

Some people report feeling more tired than usual after starting amlodipine.

6. Heart Palpitations

Amlodipine can occasionally cause awareness of your heartbeat, such as:

• Fluttering sensations
• Faster heartbeat
• Pounding heartbeat

Persistent or severe palpitations should be checked.

7. Nausea or Stomach Discomfort

Digestive symptoms may include:

• Nausea
• Abdominal discomfort
• Changes in bowel habits

8. Sleep Problems

Some people report:

• Trouble sleeping
• Unusual tiredness during the day

Sleep changes can have many causes, so discuss persistent symptoms with a healthcare professional.

9. Muscle Cramps or Weakness

Some people experience muscle discomfort or cramps. If weakness is severe or unusual, seek medical advice.

10. Gum Overgrowth (Gingival Hyperplasia)

Amlodipine can rarely cause gum swelling or overgrowth.

Helpful steps include:

• Good dental hygiene
• Regular dental check-ups
• Reporting changes to your dentist or doctor

11. Low Blood Pressure Symptoms

If blood pressure drops too much, symptoms may include:

• Fainting
• Severe dizziness
• Weakness
• Confusion

Seek medical advice if these occur.

12. Allergic Reaction (Rare but Serious)

Get urgent medical help if you develop:

• Swelling of the face, lips, tongue, or throat
• Difficulty breathing
• Severe rash

When to Contact Your Doctor

Speak with a healthcare professional if you experience:

• Persistent or worsening ankle swelling
• Fainting
• New chest pain
• Severe dizziness
• A rapid or irregular heartbeat
• Symptoms that interfere with daily life

Do not stop taking amlodipine suddenly without medical advice. Your healthcare provider can adjust the dose or consider alternatives if needed.
