Amlodipine users warned ‘call 111’ for serious side effect
Amlodipine lowers blood pressure, which can sometimes cause dizziness or lightheadedness, particularly when treatment is started or the dose is increased.
You may feel unsteady when standing up, walking, or getting out of bed.
The risk can be greater if you are dehydrated, take other blood-pressure-lowering medications, or have a naturally low blood pressure.
How to Reduce the Risk
Move slowly when getting out of bed or standing up from a chair.
If you feel dizzy, sit or lie down until the sensation passes, and avoid driving or operating machinery while affected.
If dizziness is persistent, severe, or associated with unusually low blood pressure, contact your healthcare professional.
Fainting, chest pain, severe weakness, or difficulty breathing requires urgent assessment.
3. Headaches
Headaches are another recognized side effect of amlodipine, particularly when treatment begins.
They may occur as the body adjusts to changes in blood vessel function and blood pressure.
For many people, headaches improve as treatment continues.
However, a headache should not automatically be blamed on medication, especially if it is unusually severe or different from previous headaches.
Seek emergency medical attention for a sudden, extremely severe headache or one accompanied by weakness, confusion, difficulty speaking, or a sudden change in vision.
If headaches persist or interfere with daily activities, discuss them with your healthcare professional.
4. Flushing and a Feeling of Warmth
Some people experience facial flushing, warmth, or redness while taking amlodipine.
This can occur because the medication widens blood vessels.
The sensation may be more noticeable after taking the medicine or during warm weather.
Flushing without other symptoms is generally not an emergency, but persistent or troublesome symptoms should be discussed with a clinician.
If flushing occurs alongside swelling of the face or tongue, difficulty breathing, or a rapidly developing widespread reaction, seek emergency medical assistance.
5. A Fast or Noticeable Heartbeat
Some people taking amlodipine notice palpitations or a more noticeable heartbeat.
Blood vessel relaxation can sometimes produce changes in heart rate, although not everyone experiences this effect.
If palpitations are persistent, recurrent, or associated with dizziness, arrange a medical assessment.
Seek emergency help for palpitations accompanied by chest pain, severe shortness of breath, or fainting.
Do not assume that a racing heartbeat is harmless simply because you take blood pressure medication.
6. Fatigue or Unusual Tiredness
Some people report tiredness or weakness while taking amlodipine.
The cause may be related to the medication, changes in blood pressure, another medicine, or an unrelated health condition.
If fatigue begins after starting treatment, note when it occurs and whether it is improving.
Persistent or worsening fatigue deserves medical assessment, particularly when accompanied by breathlessness, swelling, dizziness, or reduced exercise tolerance.
A healthcare professional can help determine whether amlodipine is contributing or whether another explanation should be investigated.
7. Digestive Problems
Amlodipine can sometimes cause nausea, abdominal discomfort, or changes in bowel habits.
Some people experience constipation, while others notice indigestion.
Mild symptoms may improve over time, but persistent digestive problems should be discussed with a healthcare professional.
Severe abdominal pain, repeated vomiting, or other significant new symptoms should not automatically be attributed to the medication.
A clinician can assess whether treatment changes or further investigation are needed.
8. Gum Swelling or Overgrowth
A less common but recognized side effect of amlodipine is gingival enlargement, which means the gum tissue becomes swollen or grows excessively.
The gums may look thicker, feel tender, or bleed during brushing.
This problem may be more likely when dental plaque accumulates around the teeth.
What Can Help?
Brush your teeth twice daily with fluoride toothpaste and clean between your teeth regularly.
Arrange routine dental examinations and tell your dentist that you take amlodipine.
If your gums become noticeably enlarged or uncomfortable, consult your dentist and prescribing clinician.
Do not stop the medication without medical guidance. If necessary, your healthcare professional can consider alternative treatment options.
