Taking amlodipine twice can lower your blood pressure too much. Call your local poison-control service or urgent medical advice line now, even if you feel well. In the US, call Poison Control: 1-800-222-1222. The NHS also advises urgent assessment after taking more than the prescribed dose of amlodipine: NHS amlodipine advice.

Call emergency services now if you have fainting, severe dizziness, weakness, confusion, chest pain, shortness of breath, or a very slow/fast heartbeat.

Until you get advice:

Please reply with: your tablet strength (for example 5 mg or 10 mg), when you took each dose, your age, and any symptoms.

If you took two 5 mg tablets, that is 10 mg total.

Please call Poison Control or your local urgent medical advice line now for personalized guidance, particularly if you take other blood-pressure or heart medicines. In the US: 1-800-222-1222.

Do not take more amlodipine today unless they tell you otherwise. Rest, avoid alcohol, and stand up slowly.

Get emergency help immediately if you faint, have severe dizziness, trouble breathing, chest pain, confusion, or feel your heartbeat is very slow, very fast, or irregular.

Tell me what time you took each 5 mg tablet and whether you have any symptoms now.

If you took 10 mg total each day for 2 days and have had no symptoms, serious effects are less likely. But amlodipine stays in the body a long time, so please contact your pharmacist, doctor, or Poison Control today to confirm when to restart your usual dose. Do not take an additional tablet until they advise you.

For now:

Amlodipine can last 30-50 hours, so monitoring still matters. The Poison Control amlodipine guidance recommends contacting them after an overdose or unexpected extra dose.
