If you’ve been prescribed losartan, you probably want to know what it actually does and how to use it without any surprises. In simple terms, losartan is a pill that helps keep your blood pressure in a healthy range by blocking a hormone called angiotensin II. That hormone normally tightens blood vessels, and when it’s blocked, your vessels stay relaxed and blood flows more easily.
Losartan belongs to a class called ARBs (angiotensin II receptor blockers). Think of it like a key that stops the bad guy (angiotensin II) from locking up your blood vessels. When the lock is blocked, the vessels stay open, which reduces the pressure on your heart. This effect not only helps with hypertension but can also protect your kidneys, especially if you have diabetes.
Most people start seeing a drop in their numbers within a week or two, but the full effect may take a month. Your doctor will likely check your blood pressure a few times before deciding if the dose needs tweaking.
Typical adult doses range from 25 mg to 100 mg once daily, taken with or without food. Kids and teens may get lower doses, and doctors adjust based on kidney function. Never double up if you miss a dose; just take the next one at your regular time.
Common side effects are mild and include dizziness, headache, or a slight tired feeling. These usually fade as your body gets used to the medication. More serious reactions—like swelling of the face or lips, severe stomach pain, or sudden weight gain—should prompt an immediate call to your doctor.
Losartan can interact with a few other drugs. If you’re on potassium‑rich supplements, certain diuretics, or NSAIDs (like ibuprofen), watch for higher potassium levels or kidney strain. Alcohol isn’t a major problem, but heavy drinking can worsen dizziness.
Pregnant women should avoid losartan because it can harm the developing baby. If you become pregnant while taking it, let your healthcare provider know right away.
Storing the pills is easy—keep them in a dry place at room temperature, away from children. If you notice any change in the tablet’s shape or color, toss it out and get a fresh prescription.
Bottom line: losartan is a solid, once‑daily option for most people with high blood pressure, especially if you can’t tolerate ACE inhibitors. Keep track of your blood pressure, report any odd symptoms, and stay in touch with your doctor for dose adjustments. With the right use, you’ll likely see steadier numbers and fewer worries about heart‑related issues.
