Losartan is a prescription medication for blood pressure. It is an angiotensin receptor blocker which works by relaxing your blood vessels, which makes it easier for blood to pump around your body. When taken daily, Losartan can help reduce your blood pressure and reduce the risk of complications like heart attacks and stroke. If you have been taking Losartan for at least three months you can use our convenient service to order your repeat supply of tablets - without having to see your GP.

Losartan is called an angiotensin II receptor antagonist. This group of medications is often prescribed to lower high blood pressure. Angiotensin II receptor antagonists act on certain hormone receptors in your body and block the action of angiotensin II, a hormone which narrows your blood vessels and increases blood pressure levels. As a result, the hormone can not cause a rise in your blood pressure and your blood vessels remain open and relaxed.

Please note: where a generic product has been ordered we may use a range of manufacturers to provide you with your medication, in order to maintain our service levels.
Losartan potassium needs to be taken on a daily basis. It is important that you follow your doctor’s instructions carefully. Do not stop taking your blood pressure medication unless your doctor has advised you to, as this may lead to dangerous complications. You need to swallow each tablet whole with a drink of water. You can take your tablets with or without a meal.

If you forget to take a dose, just continue with the next Losartan tablet at the usual time. You mustn't take an additional dose to make up for the one you have missed. Always stick to your GP’s advice with regards to dosage.
Your GP will decide whether Losartan 50mg or 100mg are suitable for you. Depending on how well you adjust to your medication, your GP may increase or decrease the dosage in the future. It is important that you visit your local surgery regularly for check-ups, so your GP can monitor your blood pressure and make sure your treatment remains effective. Please note, product packaging may differ from the image above.

In some cases, your GP may recommend a lower dose of 25mg Losartan. This may apply if you are a patient over the age of 75, have liver problems or if you are taking diuretics.
