Additional Information

Candesartan is an angiotensin II receptor blocker used to treat high blood pressure and congestive heart failure. It works by blocking the action of angiotensin II, a substance in the body that causes blood vessels to narrow. This relaxes the blood vessels and lowers blood pressure.

Candesartan is also used in some people with heart failure after a recent heart attack. This medicine should not be used in place of other treatments for heart failure.

Angiotensin II receptor blockers (ARBs) like candesartan may cause fatal harm when taken during pregnancy. Women who are pregnant or planning to become pregnant should not take this medication unless it is absolutely necessary. If you do take candesartan while pregnant, be sure to tell your doctor if you experience any side effects.

Candesartan Side Effects

Common side effects of candesartan include headache, dizziness, drowsiness, fatigue, diarrhea, and dry cough. This medication can also cause low blood pressure, especially when you first start taking it. Be sure to drink plenty of fluids and rise slowly from a sitting or lying position to avoid dizziness and fainting. If these side effects are bothersome, talk to your doctor about other treatment options.

These drugs work by blocking the action of angiotensin II, a substance in the body that causes blood vessels to narrow. This relaxes the blood vessels and lowers blood pressure.

Why Welzo

What is the Candesartan dose in elderly patients?

The recommended dosage of Candesartan in elderly patients is the same as in other age groups. The starting dose is usually one tablet (8 mg) daily. Depending on blood pressure response, the dosage may be increased to a maximum of four tablets (32 mg) daily. Elderly patients tend to be more sensitive to the effects of Candesartan, so the starting dose should be lower in these patients.

Can I use Candesartan and drink alcohol?

It is generally recommended that you avoid drinking alcohol while taking Candesartan. Alcohol can increase the side effects of Candesartan and may make it more difficult to control your blood pressure. If you do choose to drink alcohol, do so in moderation and talk to your doctor about how much alcohol is safe for you to consume while taking Candesartan.

Is this medication suited for me?

Please get in touch with a doctor if you are unsure what medication is suitable for you. You can also complete our online consultation form to check your eligibility for the product.

How is the medication delivered?

Does Candesartan cause weight gain?

There is no definitive answer to this question as weight gain is a possible side effect of many medications. Some people may experience a small amount of weight gain while taking Candesartan, while others may not experience any weight change at all. If you are concerned about gaining weight while taking Candesartan, talk to your doctor about ways to manage your weight or possible alternatives to the medication.

Why is Candesartan taken at night?

Candesartan is usually taken once daily, at night. This allows the medication to reach its peak effect in the body during the times when blood pressure is typically at its highest (during the day). Taking Candesartan at night also helps to reduce the side effects of dizziness and headache that can sometimes occur with this medication.

How do I order my medication?

Some products only require an online consultation which approximately takes 1 minute to complete, enabling you to then buy the product. Other products will also require a prescription; in this case, you will need to complete the online consultation, and then one of our partner pharmacy prescribers or doctors will review the online consultation questions and approve the order for delivery if you are eligible to purchase the item.
