Side Effects of Amias

Updated March 23, 2017

Amias is a prescription medication used to treat some cardiovascular conditions. Like any medication, side effects may occur in patients who take Amias. These are usually minor and do not cause most people to discontinue the use of Amias.


Amias is a prescription medication that is used to treat high blood pressure and heart failure. It contains the active ingredient candesartan cilexetil. Amias is classified into a family of drugs known as angiotensin II antagonists.

By preventing the reception of the natural hormone angiotensin, Amias prevents blood vessels from narrowing. It also acts on the kidneys, causing them to excrete excess water and salt, thus lowering the liquid volume of the blood and, in turn, lowering blood pressure.

Common Side Effects

Several common side effects may occur while taking Amias. Most of these side effects are minimal and can decrease over time.

Headaches, dizziness (especially upon standing), low blood pressure (especially in heart-failure patients), decreased function of the kidneys, low white blood cell count, low levels of sodium within the blood, high levels of potassium within the blood, nausea, infections of the airway, muscle, back or joint pain, rashes on the skin, abnormal liver function, and swelling of the lips, face or tongue.

If any of these side effects becomes extremely bothersome, consult with your doctor to explore treatment options and ways to alleviate some of the side effects.

Serious Side Effects

If you should experience breathing difficulties or swelling of the face, tongue or throat, head to the nearest emergency room or dial 911. These are symptoms of severe allergic reaction to Amias and can be life threatening if left untreated.

If your skin or the whites of your eyes become yellow while taking Amias, contact your doctor immediately, as this is a sign that your liver is reacting negatively and is unable to metabolise the medicine. This is a condition called jaundice. It signifies that your liver is overwhelmed and can be fatal if left untreated.


If you are taking certain blood pressure medicines (ACE inhibitors), diuretics, potassium supplements or medicines that might increase blood potassium (such as certain contraceptives or Heparin), consult with your doctor before taking Amias to decrease the risk of side effects or drug interactions.

Pregnant or breast feeding women should not use Amias because of specific risks that are posed to the baby.

Patients with liver or kidney dysfunction should exercise extreme caution while using Amias, and do so only under a physician's direct care.

Aortic stenosis (blockage of the aorta), ischemic heart disease (inadequate blood flow to the heart) and cerebrovascular disease (blockage of blood vessels in the brain) patients should also be very carefully monitored while using Amias.


It is important to use caution when operating a vehicle or machinery while taking Amias, because dizziness and light headedness can occur repeatedly while using blood pressure-lowering medicines.

Blood tests to determine the amount of creatinine and potassium in the blood should be run intermittently while using Amias to make sure your body is handling the medicine properly.

Do not use Amias in children or teenagers, as its safety in patients under 18 has not been established.
