About Diuril (chlorothiazide)

Diuril (chlorothiazide) is a type of diuretic used to treat fluid retention (edema) in people with congestive heart failure, liver disease, or kidney disease. It's also used to treat high blood pressure.

 

Diuril is available only by prescription. It is available in a generic formulation as chlorothiazide.

 

Diuril may be prescribed as an oral suspension or intravenous injection. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.

 

If you're prescribed Diuril, be sure to complete the full course of the diuretic unless your doctor specifically tells you to stop. If you don’t complete your prescription, the diuretic may not fully treat your edema or high blood pressure.

Diuril uses

There are several FDA-approved uses for Diuril, but your healthcare provider may also prescribe it off-label to treat other medical conditions.

 

Your doctor may prescribe Diuril for any of the following reasons or other reasons not listed here. If you have questions about why a medication is prescribed, ask your online doctor or pharmacist.

Edema

Diuril is FDA-approved to treat edema (fluid retention) in people with congestive heart failure, liver disease, and corticosteroid and estrogen therapy. It can also help treat edema associated with kidney disease, incuding renal dysfunction, nephrotic syndrome, and chronic renal failure.

Diuril is not recommended for edema during pregnancy, as it may cause fetal harm.

High blood pressure

Diuril is FDA-approved to treat high blood pressure (hypertension) alone. Diuril can help reduce the risk of stroke, heart attack, and kidney problems.

In patients taking other blood pressure medications, it can enhance the effectiveness of those antihypertensive drugs to treat more severe forms of high blood pressure.

Diuril side effects

The side effects associated with taking Diuril are typically mild. Most Diuril side effects are associated with dizziness.

Diuril has some common side effects. They may include:

  • Dizziness or spinning sensation

  • Numbness or tingling

  • Stomach and muscle cramps


Other side effects, which are less common but might be more severe, could include:

  • Dark-colored urine

  • Allergic reaction

  • Easily bruising or bleeding


You should call your doctor if you notice any adverse effects, or if you develop any other new or concerning symptoms. Diuril may be prescribed off-label to treat chronic lung disease in pediatric patients.

How to take Diuril

Your pharmacist will provide you with instructions on how to take your Diuril prescription. Be sure to read your prescription label and follow the instructions. Call your doctor or pharmacy if you have any questions.

 

Diuril can come in different forms and doses, so be sure to follow the specific instructions on your prescription. The usual adult dosage is 500–1000 mg (10 mL to 20 mL) once or twice daily.

 

Shake the oral suspension before measuring a dose. Use the dosing syringe provided, or use a medicine dose-measuring device.

 

Diuril IV injection is given as an infusion. Your healthcare provider will administer the injection in a hospital setting if you cannot take the medication by mouth.

 

In diabetic patients, dosage adjustments of insulin may be required.

What to avoid while taking Diuril

Diuril has 419 drug interactions. Don’t change what you are taking without checking with your doctor or pharmacist. That includes other medications, supplements, and drug therapy.

Possible drug interactions with Diuril include:

  • Other antihypertensive drugs

  • Cholestyramine or colestipol

  • Lithium

  • Insulin or oral diabetes medicine

  • Steroid medicine

  • Nonsteroidal anti-inflammatory drugs (NSAIDs)

 

Because alcohol can lower blood pressure, drinking alcohol while taking Diuril may increase the risk of adverse reactions. Talk to your doctor before drinking alcohol while on Diuril.
