Losartan Potassium (25mg/50mg) Tablet

Losartan is a widely prescribed medication belonging to the class of Angiotensin II Receptor Blockers (ARBs), primarily used for managing high blood pressure (hypertension) and protecting the kidneys from damage in Type 2 diabetes. It works by relaxing blood vessels, allowing smoother blood flow and improving the efficiency of the heart.


Primary Indications

Hypertension Management: Effectively lowers high blood pressure, thereby reducing the long-term risk of stroke and heart attack.

Protecting Kidneys (Nephropathy): Helps slow the progression of kidney damage in patients with hypertension and Type 2 diabetes.

Prevention of Strokes: Commonly prescribed for individuals with left ventricular hypertrophy (LVH) to reduce the risk of stroke.


How to Use Losartan

Consistency is Key: Take your tablet at the same time every day to maintain a stable drug level in your system.

With or Without Food: Losartan can be taken with or without food, but consistency helps ensure stable absorption.

Avoid Potassium Supplements: Since Losartan may increase potassium levels (hyperkalemia), avoid supplements or salt substitutes unless advised by your doctor.

Initial Dizziness: You may experience light-headedness initially. Rise slowly from a sitting or lying position to prevent dizziness.


Vital Safety Precaution

Pregnancy Warning: Losartan must be discontinued during pregnancy, as it can cause serious harm or even be life-threatening to the unborn fetus, especially in later trimesters.

Hydration: In cases of severe diarrhea, vomiting, or dehydration, seek medical advice promptly, as this may lead to a dangerous drop in blood pressure.

Liver and Kidney Function: Inform your doctor about any liver or kidney conditions, as dose adjustments may be required.


Adverse Effects

While Losartan is generally well tolerated, some individuals may experience:

  • Upper respiratory tract infections (flu-like symptoms)
  • Dizziness or fatigue
  • High potassium levels (hyperkalemia)

Seek immediate medical attention if you notice swelling of the face, lips, or throat, as this may indicate a serious allergic reaction.

Q: How long will Losartan take to lower my blood pressure levels?
A: Blood pressure may begin to improve within 1 week, but full effects are typically seen within 3–6 weeks. Continue taking it as prescribed.

A: Alcohol may increase side effects like dizziness and fainting. It is best to limit or avoid alcohol while on this medication.
