Losartan
If you or someone you care for has been prescribed Losartan, you probably want straightforward answers: what it treats, how it works, common side effects, and how to use it safely. This page gives quick, practical information so you can talk to your doctor with confidence.
How Losartan works and who uses it
Losartan belongs to a class called angiotensin receptor blockers (ARBs). It relaxes blood vessels, which lowers blood pressure and reduces stress on the heart. Doctors commonly prescribe it for high blood pressure, for protecting the kidneys in people with type 2 diabetes, and sometimes for heart failure. People who developed a cough on ACE inhibitors often switch to an ARB like Losartan without that side effect.
Treatment goals vary: lower blood pressure numbers, reduce protein loss in urine, or improve heart function. Typical adult doses range from a low starting dose up to higher maintenance doses; your doctor will pick the right dose based on your condition, other medicines, and kidney function.
What to watch for: side effects, interactions, and safety tips
Most people tolerate Losartan well, but watch for lightheadedness—especially when standing up suddenly—because blood pressure can drop. Other possible issues include increased potassium levels, changes in kidney function, or dizziness. If you get severe swelling, trouble breathing, or fainting, seek emergency care.
Avoid combining Losartan with potassium supplements, salt substitutes that contain potassium, or certain blood pressure drugs without medical advice — these raise the risk of high potassium. NSAIDs (like ibuprofen) can reduce how well Losartan works and may affect kidneys. Never take Losartan if you are pregnant or planning pregnancy; it can harm the baby.
Get blood tests after starting or changing dose: a basic check of kidney function and potassium is standard. Keep a home blood pressure log for a week or two after changes so your doctor can see trends.
Want to stop or switch meds? Don’t stop Losartan suddenly. Talk with your prescriber about the safest way to change therapy.
Shopping for Losartan online? Use only licensed pharmacies that require a prescription. Avoid sellers that offer to ship prescription drugs without a valid prescription or those with unclear contact information. Check for review or verification badges, and pick pharmacies that list a pharmacist contact or have clear return policies. If a price looks too low to be real, it may be counterfeit or unsafe.
Combine medication with simple lifestyle steps: reduce salt, aim for 150 minutes of moderate exercise per week, limit alcohol, and eat more vegetables. Those habits often help blood pressure meds work better and can lower your overall risk.
Questions to ask your prescriber: Why Losartan for me? What dose should I start with? When should I get blood tests? What other medicines should I avoid? Write these down before your appointment so you don’t forget.
