How does Losartan work?

Losartan is called an angiotensin II receptor antagonist. This group of medications is often prescribed to lower 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. As a result, the hormone can not cause a rise in your blood pressure and your blood vessels remain open and relaxed.

How are Losartan tablets taken?

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.

Which Losartan dosage do I need?

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.

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.
