Losartan, an angiotensin II receptor antagonist, is a commonly prescribed medication for hypertension (high blood pressure) and diabetic nephropathy. Understanding its side effects, especially at higher doses like 100 mg, can empower patients to make informed decisions about their health.
1. Overview of Losartan
Losartan works by blocking the effects of a chemical called angiotensin II. This causes blood vessels to relax, leading to a reduction in blood pressure. While effective, losartan, especially at doses like 100 mg, can lead to a variety of side effects.
2. Common Side Effects
The following are some of the most commonly reported side effects associated with losartan:
- Dizziness or Lightheadedness: Often occurs when you first start taking the medication or when your dose is increased.
- Fatigue: Some people may feel unusually tired when taking losartan.
- Stomach Pain: This can range from mild discomfort to severe pain.
- Nasal Congestion: A stuffy nose can be a less common side effect.
- Back or Leg Pain: Muscular discomfort has been noted by some users.
3. Serious Side Effects
While rare, there are some serious side effects you should be aware of:
- Kidney Problems: Symptoms include changes in urine amount, swelling in your feet, or loss of appetite.
- High Potassium Levels: This can lead to a slow or irregular heartbeat.

The side effects you might experience can depend on:
- Dosage: Higher doses, like 100 mg, may lead to more pronounced side effects.
- Age: Older adults may be more sensitive to the effects of losartan.
