If your doctor mentioned Losartan, you probably wonder what it does and why it’s prescribed. In plain terms, Losartan is a pill that helps lower high blood pressure and protects the heart. It belongs to a group called ARBs (angiotensin II receptor blockers) and is taken once a day by most people.
Why does it matter? High blood pressure can damage arteries, strain the heart, and lead to strokes. Losartan slows that process by relaxing blood vessels, making it easier for blood to flow. The result is lower pressure numbers and less work for your heart.
Losartan blocks a chemical called angiotensin II, which normally tells your blood vessels to tighten. When the block is in place, the vessels stay relaxed, blood flows smoother, and pressure drops. This effect shows up within a few hours, but the full benefit may take a few weeks of consistent use.
Typical dosing starts at 50 mg once daily, and doctors can increase it up to 100 mg if needed. You can take it with or without food, but try to be consistent—take it at the same time every day so your body gets used to the rhythm.
Most people tolerate Losartan well, but a few side effects pop up now and then. Common ones are dizziness, light‑headedness, or a mild headache—usually when you first start. If you feel unusually weak, notice swelling in your ankles, or develop a persistent cough, call your doctor.
Because Losartan can affect kidney function, doctors often check blood work after the first month. If you have kidney disease or are on a diuretic, your dose might need adjustment. Also, avoid potassium‑rich supplements unless your doctor says it’s safe; Losartan can raise potassium levels.
Pregnancy is a big no‑no for Losartan. If you become pregnant while on the drug, tell your doctor right away—there’s a safer alternative for that situation.
Missed a dose? Just take it as soon as you remember, unless it’s almost time for the next one. Don’t double up; that can raise the chance of low blood pressure.
When you’re getting a refill, look for the same brand or generic version your doctor prescribed. Switching between different manufacturers usually isn’t a problem, but keep an eye on any new side effects.
