hydrochlorothiazide + valsartan
Summary
Hydrochlorothiazide and valsartan are used to treat high blood pressure, which is also known as hypertension. By lowering blood pressure, they help reduce the risk of complications such as heart attack, stroke, and kidney problems. Hydrochlorothiazide may also be used to treat fluid retention, which is known as edema, associated with conditions like heart failure. Both medicines work together to provide a comprehensive approach to managing cardiovascular health.
Hydrochlorothiazide works by helping the kidneys remove excess salt and water from the body, which reduces fluid buildup and lowers blood pressure. Valsartan works by blocking a substance called angiotensin II, which causes blood vessels to tighten. By blocking this substance, valsartan helps relax and widen blood vessels, further lowering blood pressure. Together, they provide a more comprehensive approach to managing high blood pressure by addressing both fluid retention and blood vessel constriction.
The usual adult dose of hydrochlorothiazide ranges from 12.5 mg to 50 mg per day, depending on the condition being treated. Valsartan is typically prescribed in doses ranging from 80 mg to 320 mg per day. When combined, the specific dose will depend on the individual's health needs and response to treatment. It's important to follow the healthcare provider's instructions and not adjust the dose without consulting them. Regular monitoring helps ensure the correct dosage is maintained.
Common side effects of hydrochlorothiazide include increased urination, dizziness, and electrolyte imbalances, which refer to changes in the levels of minerals in the blood. Valsartan may cause dizziness, fatigue, and headache. Both medicines can lead to low blood pressure, which is a significant adverse effect. Rarely, valsartan can cause kidney problems, while hydrochlorothiazide may lead to gout, which is a type of arthritis caused by excess uric acid. Monitoring is essential to manage these side effects effectively.
Hydrochlorothiazide is generally not recommended during pregnancy as it can affect the fluid balance in the body. Valsartan is contraindicated during pregnancy, especially in the second and third trimesters, as it can harm the developing fetus. Both medicines can lead to complications if used during pregnancy, so alternative treatments are usually recommended. It's crucial for pregnant women to consult their healthcare provider before using these medications to ensure the safety of both mother and baby.
