Summary
Metolazone is used to treat high blood pressure, which is when the force of blood against your artery walls is too high, and fluid retention, which is when your body holds onto excess water. It helps reduce swelling and lower blood pressure, making it useful for people with heart failure or kidney problems.
Metolazone works by helping your kidneys remove extra salt and water from your body. This action reduces the amount of fluid in your blood vessels, which lowers blood pressure and reduces swelling. Think of it like a sponge soaking up extra water.
The usual starting dose of Metolazone for adults is 2.5 mg to 5 mg once daily. Your doctor may adjust your dose based on your response and specific health needs. The maximum recommended dose is typically 20 mg per day. Always follow your doctor's specific dosing instructions.
Common side effects of Metolazone include dizziness, headache, and muscle cramps. These effects are usually mild and vary from person to person. If you notice new symptoms after starting Metolazone, talk with your doctor before stopping any medication.
Metolazone can cause dehydration, which means your body doesn't have enough fluids, and electrolyte imbalances, which are changes in the levels of minerals in your blood. Avoid if you have severe kidney problems or low potassium levels. Always follow your doctor's advice and report any new or worsening symptoms.
