What is Losartan used to treat?
Losartan is most commonly used to treat high blood pressure (HBP) and any conditions related to the effects of HBP. Losartan can also help to treat other serious illnesses, including heart failure, kidney disease, strokes and heart attacks when used regularly.
Losartan works by blocking angiotensin II, which is a peptide hormone linked to causing blood pressure to rise. This helps to relax the blood vessels.
It can be used on its own or combined with certain other medicines prescribed to treat high blood pressure.
The active ingredient in this medicine is losartan potassium.
Your doctor may prescribe you Losartan tablets if you have taken other medicines to treat blood pressure conditions in the past, such as ramipril and lisinopril, but suffered side effects as a result of taking them; common adverse effects from these medicines include a dry cough.
Who can take Losartan?
Losartan tablets are normally only prescribed to adults over the age of 18 years old. However, children over the age of 6 can take it if they suffer from high blood pressure. The dosage will differ from patient to patient, depending on the illness you are being treated for.
This medicine is not suitable for everyone to use. You should tell your doctor before taking Losartan tablets if you have any of the following conditions:
- You are pregnant, you think you might be pregnant or are trying to get pregnant
- You have low blood pressure
- You have diabetes
- You have had an allergic reaction to Losartan or any other medication in the past
- You are currently breastfeeding
- You have any heart, liver or kidney problems
- You have recently had a kidney transplant
- You have been on a low-salt diet
- You currently suffer from diarrhoea or vomiting
There may be other conditions that make you unsuitable to take Losartan tablets. You should refer to the patient information leaflet that will be included with your order before you start a course of treatment.
Possible side effects
As is the case with all medicines, you may experience certain side effects while taking Losartan tablets.
Not everyone will suffer from side effects, and most cases will improve as your body gets used to the medication.
Common side effects that you may experience include:
- Feeling sick
- Being sick
- Experiencing vertigo - having a dizzy or spinning feeling
- Pain in your muscles or joints
These side effects are common, but you should still speak to your doctor or pharmacist if these symptoms worry you or do not go away.
This list is not exhaustive; for the more serious adverse reactions you may experience while taking this medicine, please refer to the Side Effects tab on this product's page
Losartan tablets should be taken once a day. As with all medicines, you should always ensure you thoroughly read through the patient information leaflet before you take it.
Make sure you follow the instructions given to you by your doctor or pharmacist, who might suggest you take your first dose of Losartan before you go to bed, to avoid a common side effect of feeling dizzy.
You can take these tablets either with or without food, but they should always be swallowed whole with a drink of water.
It is vital that you keep taking Losartan even if you start to feel better; you will still be getting the benefits this medicine provides.
How much Losartan will I need to take?
The dosage of Losartan you will need to take will be dependent upon the condition you are being treated for. Your doctor will advise you on how much to take and you should make sure you stick to this amount.
Most adults will take between 50mg and 100mg of Losartan each day as a treatment for high blood pressure, and also to safeguard against kidney problems.
For heart failure, your doctor or pharmacist will usually instruct you to take between 12.5mg to 150mg once a day.
If you have a child who is required to take Losartan tablets, your doctor base the dosage they require on the child's weight.
If you have recently lost a significant amount of bodily fluid from conditions like having diarrhoea or being sick, your dosage may be lower than the average adult. Your doctor will probably advise taking Losartan in lower doses if you are aged 75 or over.
What if I forget to take it?
If you forget to take Losartan, just take the dose as soon as you remember, as long as it is not nearly time for your next scheduled dose.
Never take an extra dose to make up for missing a previous one.
To make sure you don't miss taking your Losartan tablets, it may help to set an alarm to remind you. Taking Losartan at the same time each day helps you to develop a routine, meaning you are less likely to forget to take the tablets.
What if I take more than I am supposed to?
The amount of Losartan that constitutes as an overdose varies from person to person, but it is important that you contact your doctor or go to the nearest A&E department immediately if you do take more tablets than you should.
If you take too much Losartan, you may experience dizziness, a pounding heartbeat or sleepiness.
If you do overdose on Losartan tablets, you should not drive yourself to hospital; you should either call an ambulance or get someone else to take you there. Make sure you take your medicine with you.
