Valsartan, while generally well-tolerated, can cause side effects. Many are mild and transient. Frequency varies, depending on the dosage and individual patient factors.
Common side effects include dizziness, headache, and diarrhea. These typically occur at lower frequencies with lower doses. Upper respiratory tract infections (like colds) are also reported, but a direct dose-relationship hasn’t been definitively established.
Less common, but still possible, are high potassium levels (hyperkalemia), particularly in patients with kidney problems or those taking other medications affecting potassium levels. This risk increases with higher doses. Always inform your doctor about all medications you’re taking.
Serious side effects, though rare, include angioedema (swelling of the face, lips, tongue, or throat). This is a medical emergency requiring immediate attention. Angioedema’s association with valsartan dose is complex and not fully understood, but prompt reporting is crucial.
Liver problems are another potential concern, though infrequent. Regular blood tests are sometimes recommended, especially for patients with pre-existing liver conditions or those taking higher doses. Your doctor will guide you on necessary monitoring.
Remember, this information doesn’t replace professional medical advice. Always discuss any concerns with your doctor or pharmacist before starting, stopping, or changing your medication. They can assess your individual risk factors and determine the appropriate dose for your needs.
