Common side effects of amlodipine/olmesartan include swelling, flushing, and palpitations (a pounding or racing heartbeat). Amlodipine/olmesartan can cause dizziness and drowsiness. Do not drive or operate heavy machinery until you know how amlodipine/olmesartan affects you.

Serious side effects have been reported with amlodipine/olmesartan including:
- hypotension. Excessive sweating and dehydration may lead to an excessive fall in blood pressure (hypotension). Vomiting or diarrhea may also lead to a fall in blood pressure.
- coronary artery disease (CAD). When starting or increasing the dose of amlodipine/olmesartan, those with CAD may experience an increase in the frequency, duration, or severity of chest pain or a heart attack if these events do happen to occur.
- decline in kidney function. Your doctor may need to perform tests to determine the stability of the function of your kidneys, especially in patients who already have kidney dysfunction. In addition, It is recommended to avoid use of both amlodipine/olmesartan and the medication aliskiren if you already have kidney impairment.
- liver dysfunction. Since amlodipine (an active ingredient of amlodipine/olmesartan) is broken down by the liver, your doctor may need to exercise extra caution when choosing the dose of amlodipine/olmesartan in those with severe liver dysfunction.
- severe diarrhea and weight loss. Severe, chronic diarrhea with considerable weight loss may develop months to years after starting this medication. Tell your doctor if you are experiencing these symptoms.
