Interactions between your drugs

Moderate

hydrochlorothiazide ↔ metformin

Applies to:Zestoretic (hydrochlorothiazide/lisinopril) and metformin

Talk to your doctor before using hydroCHLOROthiazide together with metFORMIN. HydroCHLOROthiazide can increase blood sugar levels and interfere with diabetic control. You may need a dose adjustment or more frequent monitoring of your blood sugar to safely use both medications. Due to its effects on the kidneys, hydroCHLOROthiazide can also increase the risk of a rare but serious and potentially life-threatening condition known as lactic acidosis that may occasionally occur during treatment with metformin-containing products. Lactic acidosis is caused by a buildup of lactic acid in the blood, and is more likely to occur if you have kidney or liver disease, acute or unstable congestive heart failure, dehydration, or an excess intake of alcohol. You should seek immediate medical attention if you develop potential signs and symptoms of lactic acidosis such as fatigue, weakness, muscle pain, increasing drowsiness, abdominal pain or discomfort, fast or irregular heartbeat, difficult or rapid breathing, chills, and other unusual symptoms. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
