About Metolazone
Metolazone is a prescription medicine used to treat excess fluid accumulation and swelling in the body. Doctors commonly prescribe it to help patients who have fluid buildup caused by congestive heart failure or kidney disorders. It is also used to help lower and manage high blood pressure.
For the best results, you should take this medicine consistently every day, usually once daily in the morning. You can take it with or without food, but it is best to choose one way and stick to it with every dose. Adopting a low-salt diet and staying active can also greatly improve how well this medicine works for you.
While taking this medicine, you might experience mild side effects like dizziness, mild headaches, or muscle cramps. However, if you experience serious symptoms such as severe muscle weakness, a fast or irregular heartbeat, or extreme dry mouth and thirst, you must contact your doctor immediately.
Do not take this medicine if you are unable to pass urine or if you have severe liver damage. Before starting, tell your doctor if you have a history of gout, diabetes, or kidney disease, as they may need to adjust your treatment plan.
This medication can interact with other drugs like pain relievers and certain heart medicines, and drinking alcohol while taking it can make you feel dangerously dizzy. If you are pregnant, planning a pregnancy, or breastfeeding, discuss the potential benefits and risks of treatment with your doctor before using Metolazone. Your doctor will determine whether this medicine is appropriate for your individual situation.

Patients Concern
Disease/Condition Glossary
Oedema: Oedema is a build-up of fluid in the body, which causes the affected tissue to become swollen. It can occur due to immobility, certain medical conditions and medications.
High blood pressure (hypertension): It is a condition in which the blood exerts increased pressure on the walls of blood vessels, leading to hypertension. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Raised blood pressure can cause chest pain (angina) and a heart attack. Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. Symptoms of high blood pressure include headache, dizziness, nose bleed, changes in vision, chest pain, weakness and dyspnoea (shortness of breath). However, most of the time, the signs and symptoms of hypertension are none.
