High Blood Pressure

What are the side effects? Sometimes a medicine causes unwanted effects. These are called side effects. Not all of the side effects for diuretics are listed here. If you feel these or any other effects, you should check with your doctor. Common side effects: Weakness Muscle cramps Skin rash Increased sensitivity to sunlight (with thiazide diuretics) Throwing up Diarrhea Cramps Dizziness or lightheadedness Joint pain Less common side effects: Impotence or decreased sexual desire Rare side effects: Irregular heartbeat (arrhythmia) Again, tell your doctor right away if you have any of these side effects. Do not stop taking your medicine unless your doctor tells you to. If you stop taking your medicine without checking with your doctor, it can make your condition worse.
