Valsartan is an angiotensin II receptor blocker (ARB) used primarily to treat high blood pressure (hypertension) and heart failure and to improve survival after a heart attack. It works by blocking the action of angiotensin II, a substance in the body that causes blood vessels to tighten, which helps to relax and widen blood vessels, thereby lowering blood pressure and improving blood flow.
Common Uses:
- Hypertension: It is often prescribed to manage high blood pressure, either alone or in combination with other antihypertensive medications.
- Heart Failure: It is used to treat heart failure, helping to reduce the risk of hospitalization and improve symptoms.
- Post-Heart Attack: Valsartan can be prescribed after a heart attack to improve survival and reduce the risk of further cardiovascular events.
Dosage:
- Dosage adjustments for Valsartan depend on the underlying health condition. This medication is usually taken once or twice a day, with or without meals.
- Common starting doses range from 40 mg to 160 mg daily, but your doctor will determine the appropriate dose based on your specific condition and response to treatment.
Side Effects:
Common side effects of valsartan may include:
- Dizziness
- Fatigue
- Headache
- Stomach pain
- Diarrhea
Serious side effects are rare but may include:
- Kidney problems
- High potassium levels (hyperkalemia)
- Swelling (angioedema)
- Low blood pressure (hypotension)
Precautions:
- Pregnancy: It should not be used during pregnancy, especially in the second and third trimesters, as it can harm the developing fetus.
- Kidney Function: Patients with kidney disease should use Valsartan with caution, as it can affect kidney function.
- Potassium Levels: It can increase potassium levels, so patients should avoid potassium supplements or salt substitutes unless advised by their doctor.
Drug Interactions:
Valsartan may interact with other medications, including:
- Other blood pressure medications
- Diuretics (water pills)
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Potassium-sparing diuretics or potassium supplements
Always update your doctor on your current medications and supplements to minimize interaction risks. If you have been prescribed Valsartan, take it as directed by your healthcare provider and report any unusual symptoms or side effects promptly.
