Hydrochlorothiazide

Hydrochlorothiazide is a drug known as a thiazide diuretic, or water pill. It is prescribed to treat fluid retention in patients with certain liver, kidney, and heart disorders, including hypertension (high blood pressure). Hydrochlorothiazide works by keeping your body from absorbing too much salt. If your body absorbs too much salt, you will then retain fluid. Hydrochlorothiazide is sometimes prescribed with Irbesartan in a combination drug called Avalide, and with Triamterene in a drug called Dyazide. Hydrochlorothiazide dosing can range from 25 mg to 100 mg.

Side effects of Hydrochlorothiazide such as constipation, blurry vision, and stomach pain are generally minor, and should be reported to your doctor as a precaution. Allergic reactions and more serious side effects like irregular heartbeat, jaundice (yellowing of the skin), or numbness call for immediate medical attention. Rare side effects of Hydrochlorothiazide include development of certain conditions such as liver problems or gout. Hydrochlorothiazide is a class "B" drug, so it is not thought to cause harm when taken by pregnant or breastfeeding women. However, you should still discuss the possible risks of Hydrochlorothiazide use with your doctor if you are pregnant or nursing, or plan to become pregnant or begin nursing. You should not drink alcohol while you are taking Hydrochlorothiazide. If you have any previous medical conditions, especially diabetes, gout, or an inability to urinate, you must inform your doctor before beginning Hydrochlorothiazide. Certain medications may also interfere with Hydrochlorothiazide, such as insulin, aspirin or other blood pressure medications. Digoxin may also cause potassium deficiency in patients who also take Hydrochlorothiazide. Tell your doctor about any prescription, over the counter, or herbal medications you are currently taking or plan to begin taking.

Symptoms of Hydrochlorothiazide overdose include thirst, dizziness, and nausea. Seek immediate medical attention if you think you have overdosed on Hydrochlorothiazide. You should follow your doctor's prescription exactly to avoid this danger. You may also become more prone to dehydration while taking Hydrochlorothiazide. To avoid this dangerous condition, you must be sure to drink plenty of water, especially in hot weather.

Never take Hydrochlorothiazide without being under a doctor's care, as you will need to be regularly monitored for signs of harmful effects. Your doctor may require blood and/or urine samples from you frequently. Hydrochlorothiazide use may interfere with certain blood tests, so mention that you take this medication to any specialist or other doctor who needs to do blood testing for you, especially for thyroid function.
