About Product

Buy Losartan Online UK Pharmacy

If our doctor deems the treatment suitable for you, they will issue a prescription for our UK based pharmacy to dispense and ship directly to your preferred address.

Losartan, also known as Cozaar, is a medication used to lower high blood pressure. It is an angiotensin II agonist.

It is only obtainable on prescription and is available as 50mg and 100mg tablets. Losartan is often a second-choice treatment when a patient has not responded well to another blood pressure lowering medication.

How Does Losartan Work?

Losartan is an ARB (angiotensin II receptor blocker). Angiotensin II is a chemical within the body that tightens blood vessels which can cause a high blood pressure. It also causes the body to retain fluids.

Losartan helps these blood vessels to relax. It also helps to lower the volume of blood within the body, thereby helping to lower your blood pressure and assist your heart with pumping blood around the body.

How Do I Take Losartan?

Losartan can be taken by adults over the age of 18. It comes in tablet form and should be taken once a day.

A doctor will determine whether you are a suitable candidate for Losartan.

Your dose will be determined by your doctor, but it is usually taken in 50mg tablets. Those over 75 and people who have recently lost bodily fluids will need to take a lower dose.

You may be advised to take it just before bed for the first dose, but it can then be taken at any time of the day. It must be taken at the same time each day.

You can take Losartan with or without food, though it is advisable to take Losartan with food to prevent feelings of dizziness. Swallow the tablets with a glass of water.

Do not stop taking Losartan even on the days you feel well; you must continue to take the medication daily as you will still be deriving benefits from the medicine.

If you are unsure how to take Losartan, speak to your doctor or a pharmacist before you buy Losartan online.

Side effects and cautions

Losartan, much like any other medicine, carries a number of potential risks and may not be suitable for everyone. Understanding the risks associated with any medication you are taking is an important part of your treatment.

Frequently asked questions

What should I do if I forget to take Losartan when I should?

If you forget to take a dose of Losartan, take it as soon as you remember. Never take two tablets at once (“double dose”). If you regularly forget to take your tablet, you should try setting an alarm to remind yourself. Talk to your doctor or pharmacist as they may be able to recommend alternate methods to help you remember.

What should I do if I take too much Losartan?

If you take too much Losartan you should ring the NHS emergency helpline on 101, ring your doctor or head to A&E as soon as possible.

Do not drive; get someone to take you to A&E.

Keep the medicine and packaging with you as you may need to answer some questions.

Can I drink alcohol while taking Losartan?

Alcohol can lower the blood pressure and when this is combined with blood-lowering medication such as Losartan, this can be dangerous. It is therefore advisable that users avoid alcohol while being treated with Losartan.

Will Losartan impact my ability to drive or operate machinery?

Losartan can sometimes make users feel dizzy or light-headed, particularly when first taking it. If you feel dizzy it is important that you do not drive a car, ride a bike or operate machinery.
