Here are 12 common things to watch out for:
1. Swelling (edema)
Especially in the ankles, feet, or lower legs. This is one of the most common effects.
2. Flushing
A feeling of warmth or redness in the face or neck.
3. Headache
Often mild to moderate, usually early in treatment.
4. Dizziness or lightheadedness
More likely when standing up quickly due to lowered blood pressure.
5. Fatigue
Some people feel tired or low on energy.
6. Palpitations
A sensation of fast or strong heartbeat.
7. Nausea
Mild stomach upset or queasiness.
8. Abdominal pain
Sometimes mild discomfort or cramping.
9. Sleepiness or drowsiness
Not very common, but can occur in some people.
10. Gum swelling (gingival hyperplasia)
Uncommon but notable—overgrowth or swelling of gums, especially with long-term use.
11. Muscle cramps
Occasional leg or muscle cramping.
12. Low blood pressure (hypotension)
Can cause weakness, dizziness, or fainting, especially if dose is too high or combined with other BP medicines.
When to seek medical help
Get urgent advice if you notice:
- Severe dizziness or fainting
- Chest pain that worsens
- Severe swelling or sudden weight gain
- Allergic reactions (rash, swelling of face/lips, breathing trouble)
Important note
Most people taking Amlodipine tolerate it well, and side effects often improve after the first 1–2 weeks.
If you want, I can also explain how to reduce swelling or dizziness while taking it, or compare it with other blood pressure medicines.
