Esidrex – Hydrochlorothiazide uses, dose and side effects


25 mg tablet 


Esidrex is a diuretic and antihypertensive drug. The decrease in blood pressure is partly due to the diuretic effect but probably also due to the dilation of certain blood vessels ( arterioles ).

Esidrex is used for high blood pressure, fluid retention ( edema ), and Ménière’s disease (an inner ear disease).

The hydrochlorothiazide contained in Esidrex may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

Contact your doctor if you are pregnant or think you may be pregnant. Your doctor will usually suggest you take another medicine instead of Esidrex as Esidrex is not recommended during pregnancy. This is because Esidrex passes into the fetus and can cause harm to the fetus and the newborn baby if used during the last 6 months of pregnancy.

Always take Esidrex exactly as your doctor has told you. Ask your doctor or pharmacist if you are unsure.

– 1-2 tablets ( edema ),

The recommended dose of Esidrex should be taken in the morning (as a single dose) or divided into two doses, morning and evening if your doctor thinks it is best for you. Swallow the tablets with a glass of water.

The increased urine excretion begins about 2 hours after ingestion, is greatest after about 4 hours, and lasts about 12 hours.

If you take more Esidrex than you should
