Side Effects of Valsartan 80 mg

Valsartan is an angiotensin II receptor blocker (ARB) commonly used to treat high blood pressure (hypertension), heart failure, and to improve survival after a heart attack. While generally well-tolerated, valsartan can cause some side effects, particularly at higher doses or in individuals with certain conditions.

Common Side Effects:

1. Dizziness or Lightheadedness:
   • Dizziness is a common side effect, especially when starting the medication or increasing the dose. This can be more pronounced if taken while standing up quickly due to its blood pressure-lowering effect.
2. Fatigue:
   • Some individuals may feel tired or fatigued, particularly when adjusting to valsartan.
3. Low Blood Pressure (Hypotension):
   • Valsartan may cause low blood pressure, especially in those who are also taking diuretics or who are dehydrated. This can result in symptoms like dizziness, fainting, or blurred vision.
4. Headache:
   • Headaches are reported, especially in the early stages of treatment.
5. Cough:
   • A persistent cough can sometimes develop, though this is less common with valsartan compared to ACE inhibitors.

Serious Side Effects:

1. Kidney Dysfunction:
   • Valsartan can affect kidney function, particularly in people with pre-existing kidney issues. Symptoms may include swelling, weight gain, or a significant decrease in urination. Regular monitoring of kidney function through blood tests is recommended.
2. High Potassium Levels (Hyperkalemia):
   • Valsartan may increase potassium levels in the blood, which can cause irregular heartbeats, muscle weakness, or numbness. It is essential to monitor potassium levels, especially for those on potassium supplements or other medications that raise potassium.
3. Allergic Reactions:
   • Rarely, individuals may experience severe allergic reactions, including rash, itching, swelling of the face or throat, and difficulty breathing. Immediate medical attention is needed in such cases.
4. Angioedema:
   • Although rare, valsartan can cause angioedema (swelling under the skin, especially around the eyes, lips, throat, or tongue), which can lead to difficulty breathing or swallowing and requires emergency treatment.
5. Heart Failure Symptoms:
   • Valsartan is used to treat heart failure, but in some rare cases, it may worsen heart failure symptoms, such as shortness of breath, fatigue, or swelling in the legs or ankles.

Long-Term Use Considerations:

• Kidney and Liver Function: Long-term use of valsartan requires regular monitoring of kidney and liver function to avoid potential complications.
• Electrolyte Imbalance: Valsartan can lead to electrolyte imbalances, such as low sodium or high potassium, particularly when used with other medications like diuretics.

Who Should Avoid Valsartan?

• People with severe kidney or liver disease.
• Those with a history of angioedema related to previous ARB or ACE inhibitor use.
• Pregnant women: Valsartan can cause harm to an unborn baby and should be avoided during pregnancy.
