What is losartan?

Losartan is a blood pressure medication that belongs to a class called angiotensin II receptor blockers (ARBs). It’s used to treat:

  • High blood pressure (hypertension)
  • Heart failure
  • To help protect the kidneys in people with type 2 diabetes and high blood pressure

Losartan is usually taken once a day, but in some cases, your doctor may prescribe it twice daily depending on your blood pressure and how well you're responding to treatment.

It’s important to take it at the same time each day to maintain steady blood levels and keep your blood pressure under control.

How does losartan work?

Losartan works by blocking a hormone that causes blood vessels to tighten. This helps blood vessels relax, lowers blood pressure, and reduces strain on the heart.

How do I know if I qualify for losartan?

You may qualify for losartan if you’ve been diagnosed with high blood pressure and need more than one medication to get it under control.

Your healthcare provider will consider:

  • Your blood pressure readings
  • Any history of heart disease, stroke, or kidney problems
  • How you’ve responded to other medications
  • Your potassium levels and kidney function, since both drugs can affect these

It’s not usually the first treatment, but it may be prescribed if a single medication isn’t enough or if this combination fits your health needs.

Frequently
Asked
Questions

How do I know if losartan is right for me?

Losartan may be right for you if you have:

  • High blood pressure, especially if you don’t tolerate ACE inhibitors well (due to side effects like cough)
  • Type 2 diabetes with kidney involvement
  • Heart failure or a high risk of cardiovascular complications

Your healthcare provider will evaluate your blood pressure, kidney function, electrolyte levels, and overall health to decide if losartan is a good fit. It’s not right for everyone, so a brief medical review is the best way to know for sure.

When is the best time to take losartan?

The best time to take losartan is usually once a day at the same time, either in the morning or evening, depending on what works best for your routine and how your body responds. Some people feel slightly dizzy after taking it, especially at first – so taking it at night may help. Be sure to always follow your provider’s instructions and let them know before making any changes to your dosage or schedule.

Does losartan cause weight gain?

No, losartan isn’t known to cause weight changes. If you notice sudden weight gain, swelling in your legs, ankles, or hands, or shortness of breath, contact your healthcare provider. These could be signs of a more serious issue, not the medication itself.

Does losartan cause ED?

Losartan is not known to cause erectile dysfunction (ED) – in fact, for some people, it may even help improve it.

High blood pressure itself can contribute to ED by affecting blood flow, and some older blood pressure medications can make it worse. Losartan, however, tends to have a lower risk of sexual side effects, and a few small studies have suggested it might even improve sexual function in men with high blood pressure.

Does losartan slow heart rate?

Losartan does not typically slow heart rate. It works by relaxing blood vessels to lower blood pressure, but it doesn't directly affect how fast your heart beats like beta blockers do.

If you notice a slower-than-usual heart rate or symptoms like fatigue, dizziness, or fainting while taking losartan, let your healthcare provider know – it could be related to another medication or health condition.

Is losartan a blood thinner?

No, losartan is not a blood thinner. It’s a blood pressure medication in the class of angiotensin II receptor blockers (ARBs). It works by helping your blood vessels relax, which lowers blood pressure and reduces strain on the heart.

Blood thinners (like warfarin or aspirin) help prevent blood clots – they work very differently from losartan. If you need both, they can sometimes be prescribed together, but for different reasons.

What are the most common side effects of losartan?

The most common side effects of losartan include:

  • Dizziness or lightheadedness, especially when standing up
  • Fatigue
  • Nasal congestion or a stuffy nose
  • Back pain
  • Elevated potassium levels (which may show up in blood tests)

Most side effects are mild and temporary. Still, if you experience swelling of the face or throat, trouble breathing, or unusual changes in heart rhythm, contact your healthcare provider right away.
