Losartan – What You Need to Know

If you’ve been told to start a pill called Losartan, you’re probably dealing with high blood pressure or a heart‑related issue. This article breaks down the basics so you can feel confident about why it’s prescribed and how to use it correctly.

How Losartan Works & Who Should Take It

Losartan belongs to a group called ARBs (angiotensin II receptor blockers). It stops a chemical in your body from tightening blood vessels, which lowers the pressure inside them. The result is easier blood flow and less strain on your heart.

Doctors usually prescribe Losartan for:

• High blood pressure (hypertension)
• Heart failure
• Kidney protection in people with diabetes

If you have any of these conditions, your doctor might suggest Losartan as a first‑line treatment or add it to other meds. It’s also a good option if you’ve experienced cough from ACE inhibitors, another common blood‑pressure class.

Dosage, Side Effects, and Safety Tips

Typical starting doses are 50 mg once daily, but your doctor may adjust it based on how you respond. Some people need up to 100 mg a day. Always take the pill at the same time each day – morning or night works fine as long as you’re consistent.

Common side effects include:

• Dizziness, especially when standing up quickly
• Headache
• Fatigue
• Mild stomach upset

These usually fade after a week or two. If you notice severe symptoms like swelling of the face, lips, tongue, or trouble breathing, seek medical help right away – it could be an allergic reaction.

Things to watch out for:

• Potassium levels: Losartan can raise potassium, so avoid high‑potassium foods or supplements unless your doctor says otherwise.
• Kidney function: The drug is processed by the kidneys; regular blood tests help ensure everything’s okay.
• Pregnancy: Losartan isn’t safe during pregnancy. If you become pregnant while on it, contact your doctor immediately.

Mixing Losartan with certain medicines can cause problems. NSAIDs (like ibuprofen), potassium‑saving diuretics, and some antifungals may interact. Always tell your pharmacist about every drug or supplement you take.

Practical tips for success:

1. Keep a blood‑pressure log – note readings before taking the pill and share them with your doctor.
2. Stay hydrated, but don’t overdo salty snacks which can counteract the medication’s effect.
3. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one. Don’t double up.

Most people feel better within a few weeks of starting Losartan. Pairing the medication with lifestyle changes – like regular exercise, balanced diet, and stress reduction – maximizes results.
