Do you get a tightness or heaviness in your chest sometimes? There are a bunch of reasons you might feel this way. You may have a cold, or it could be something more serious. Talk to your doctor to find out what's going on. He'll want to know if you have other symptoms that can help pinpoint your condition.
Follow the label. If you are taking a single dose a day, take it in the morning with your breakfast or right afterward. If you’re taking more than one dose a day, take your last dose no later than 4 p.m.
The number of doses you take each day, the time between doses, and how long you need to take it will depend on the type of diuretic you’re prescribed and your condition.
Extreme tiredness or weakness: Both should get better as your body adjusts to the medication. If not, call your doctor.
Muscle cramps, thirst, loss of appetite, nausea, or vomiting: If you have any of these, make sure you’re taking your potassium supplement correctly, if you were prescribed one. Call your doctor if these symptoms last.
Dizziness, lightheadedness: Try getting up more slowly when you’re lying or sitting.
Blurred vision, confusion, headache, increased sweating, and restlessness: If these stick around a while or are severe, talk to your doctor.
