This is one of the most common side effects. Amlodipine widens blood vessels, which can allow fluid to accumulate in tissues. Contact your doctor if swelling is persistent, painful, or worsening, especially if it occurs with breathlessness.

You may feel dizzy when standing up or experience unsteadiness. Sit or lie down until it passes. Severe dizziness or fainting requires urgent medical assessment.

This is a major warning sign, not something to dismiss as an ordinary medication side effect. New, severe, or persistent chest pain may indicate a heart problem. Seek emergency medical care immediately.

Some people notice palpitations while taking amlodipine. If they are persistent, worsening, or accompanied by chest pain, shortness of breath, or fainting, seek urgent medical care.

Headaches can occur as your body adjusts to the medicine. Tell your doctor if they persist or interfere with daily life. A sudden, extremely severe headache warrants emergency assessment.

Your face or neck may feel warm or look red because blood vessels widen. This is usually temporary. Seek urgent help if flushing occurs with breathing difficulty or swelling of the face, lips, or tongue.

Fatigue can occur while taking amlodipine. If it is severe, persistent, or associated with fainting or breathlessness, have it assessed rather than assuming it is harmless.

Mild nausea or abdominal discomfort can occur. Sudden, severe, persistent abdominal pain, with or without vomiting, needs urgent medical assessment because rare cases of pancreatitis have been reported.

Changes in bowel habits are possible. Drink adequate fluids unless your clinician has restricted them. Seek medical advice for persistent symptoms, severe pain, or blood in your stool.

A new rash deserves medical advice, especially if it spreads. Swelling of the tongue or throat, difficulty breathing, or a rapidly developing severe allergic reaction is an emergency. Blistering or peeling skin also requires urgent care.

Yellowing can signal a liver problem. It is not a typical common side effect, but it should be assessed urgently, particularly if accompanied by dark urine, itching, or abdominal discomfort.

Amlodipine can sometimes contribute to low blood pressure. Fainting may indicate a significant problem, especially when accompanied by an abnormal heartbeat or chest pain. Seek urgent medical assessment; if the person is unconscious and unresponsive, call emergency services.
