High blood pressure and fluid retention are commonly treated with Diuril® (chlorothiazide), a prescription diuretic. In some cases, the medication is also used to treat high calcium levels in the blood. However, this is an off-label use.
Diuril comes in tablet and liquid form, and is generally taken once or twice daily. It is usually well tolerated. However, as with any medication, side effects are possible. Weakness, dizziness, and diarrhea are among the common reactions.
Be aware that Diuril can cause extreme low blood pressure in some people. This is more likely to happen when the medication is first started or the dosage is changed. It is also more likely in people who are on dialysis, have diarrhea or vomiting, or sweat a lot. This is why it is important to drink fluids regularly while taking this drug.
