What are Amias tablets used for?

Amias tablets are used as a medical treatment for high blood pressure (hypertension). They contain the active ingredient ‘candesartan cilexetil’, which belongs to the group of medicines called ‘angiotensin II receptor antagonists’.

Amias tablets reduce blood pressure by causing your blood vessels to relax and widen. This increases blood flow, and makes it easier for your heart to pump blood across your body. All of these effects help to reduce your blood pressure.

The medicine is also used to treat adult heart failure patients in specific cases: i.e. when there is reduced heart muscle function, and when ACE inhibitors cannot be used in treatment.

Who can take Amias?

Amias is a prescription medicine. You should only take Amias tablets if they have been prescribed to you by a licensed nurse or doctor. They will decide whether or not it is the appropriate treatment for you.

If you are concerned about your blood pressure levels, a medical treatment like Amias may work for you. Talk to your nurse or GP for more information.

You should not take Amias tablets if you:

  • Are allergic (hypersensitive) to any of the ingredients (e.g. candesartan cilexetil or lactose)
  • Are pregnant
  • Are breastfeeding
  • Have severe problems with your liver or gall bladder
  • Have diabetes
  • Are using certain other medicines (e.g. aliskiren)

Amias should never be given to children under 1 year of age. Always consult with your GP before taking Amias, and make sure to tell any doctor or dentist that you are taking it, before having an operation, because it can react badly combined with some anaesthetics.

Does Amias work?

There are several treatment options for people with high blood pressure. Studies show that people react differently to different medicines at different doses. What works for one person might not be as effective for another person.

However, in clinical trials, the active ingredient in Amias (candesartan cilextil) has been proven to be an effective, long-lasting treatment for high blood pressure:

  • In tests, at a dose of 8mg, most users found their blood pressure was brought back to healthy levels within 4 weeks. Other users needed an increase in dose to 16mg or 32mg to achieve this
  • Studies has shown that 81% of patients taking Candesartan for high blood pressure see a strong, positive clinical effect

Importantly, while some users experience extreme changes in their blood pressure levels after ending courses of hypertension treatment, Amias was proven to be long-lasting in its effects. This means that its users didn’t experience serious rebound effects after the end of treatment.

All in all, these results make Amias a popular treatment option amongst users during and after treatment, especially in users who were worried about the long-term effects of their prescription.

Alongside medical treatment, your doctor might also advise you to make some lifestyle changes. This will help enhance the benefit you see from your medication. These can include:

  • Taking regular exercise
  • Sticking to a balanced, low-calorie diet
  • Reducing the amount of alcohol your drink
  • Avoiding illegal drug use
  • Reducing your stress levels through relaxation techniques like meditation

Can I get Amias online?

Yes, once you’ve started your treatment with your GP or specialist, and it’s been found to be working well for you, you can reorder Amias online by using an online doctor service like Superdrug Online Doctor:

  • Once you have completed an assessment and placed your order for Amias, your online doctor will check to make sure the medication is still right for you.
  • Once they have approved the treatment, and you have paid the prescription costs, the medication will be shipped securely and quickly to your door, with no fuss.

You can also get Amias in person, at most local pharmacies or chemists, with a prescription from a licensed nurse or doctor.

How should I take my Amias?

Only ever take your medicine as directed to by your prescribing nurse or doctor. If you are unsure about how to take Amias, double-check with your GP or pharmacist to make sure.

Amias tablets should be taken every day, at about the same time (e.g. just before you go to bed). Swallow your Amias tablet with a glass of water. You can take Amias with or without food, it will make no difference.

Amias tablets come in four different dosages:

  • 4mg
  • 8mg
  • 16mg
  • 32mg

Each Amias tablet can be divided in half into two equal doses.

The usual recommended dose of Amias for the treatment of high blood pressure is one 8mg tablet per day. Your doctor may adjust (increase or decrease) this dose according to how your blood pressure responds to the treatment.

Will Amias give me side effects?

Like any medicine, Amias tablets can come with some side effects. However, everyone’s experience is different – not everybody gets side effects.

The most common side effects of Amias (affecting up to 1 in 10 users) include:

  • Feeling faint or dizzy
  • Headache
  • Cough
  • Low blood pressure
  • Respiratory infection
  • Changes to your kidney function (especially if you already have kidney problems or heart failure)

Other, very rare side effects (affecting under 1 in 10,000) are:

  • Allergic reaction
  • Skin rash, itching
  • Back pain
  • Liver problems
  • Changes in blood test results (e.g. reduced red or white blood cells, or reduced sodium levels)

Talk to your doctor before drinking alcohol if you’re taking Amias. Alcohol can make you feel dizzy or faint, when combined with the effects of Amias.

If you do ever feel tired or dizzy when taking Amias, do not drive or operate any heavy machinery. Discuss any severe or unexpected side effects with your prescribing nurse or doctor. They may advise you to switch to another form of treatment.

You can also report any unusual side effects (ones that aren’t listed in your patient information leaflet) via the Yellow Card Scheme at This helps to provide better information about the safety and side effects of Amias.
