Hydrochlorothiazide belongs to a group of medicines called thiazide diuretics. It contains an active substance: chlorothiazide.

Thiazide diuretics help to reduce the amount of water in your body. They do this by stimulating the production of urine, thus reducing blood pressure.

This medicine is indicated for the treatment of the following diseases:

- High blood pressure (elevated blood pressure) alone or in combination with other anti-hypertensive medicines.

- Edema (excessive fluid retention in tissues) due to kidney or liver disease.

- Renal diabetes insipidus (a disorder in which a defect in the small tubes (tubules)

of the kidney causes a person to eliminate a large amount of urine).

Do not take Higrotona:

- If you are allergic to clortalidona or any of the other components of this medication

(listed in section 6) or another medication that stimulates urine production (ask your doctor or pharmacist what products contain these ingredients)

- If you do not urinate at all

- If you have a severe kidney problem or severe liver disease

- If your blood potassium or sodium levels are too low or your blood calcium level is too high

- If you have ever had gout or kidney stones or are currently experiencing gout

- If you are pregnant (see section"Pregnancy, breastfeeding and fertility")

- If you have Addison's disease (also known as primary adrenal insufficiency or hypoadrenalism): a rare disorder of the adrenal glands.

Affects the production of two essential hormones called cortisol and aldosterone

.

Do not take Higrotona if you are pregnant or are trying to become pregnant (see section"Pregnancy, breastfeeding and fertility"). Inform your doctor immediately if you become pregnant during treatment with Higrotona.

Higrotona contains Sodium

This medication contains less than 1mmol of sodium (23 mg) per tablet; it is essentially "sodium-free".

The doses must be adjusted individually at all times. It is recommended to take the medication in a single dose, in the morning with breakfast.

In prolonged treatments, the lowest dose that produces an optimal effect will be used, especially in elderly patients.

-Edema of another origin: The administered dose should not exceed 50 mg/day. If an adequate response is not obtained, positive inotropic agents or an angiotensin-converting enzyme inhibitor will be administered.

-Hypertension (adults): In mild hypertension, a dose of 25 mg per day or 50 mg three times a week is often sufficient. If necessary, the dose can be increased to 50 mg per day. If blood pressure reduction is insufficient, it is recommended to associate it with other antihypertensive agents (e.g. beta-blockers, vasodilators, calcium antagonists, ACE inhibitors, reserpine), with which, in general, the dosage of each component can be kept low.

- Diabetes insipidus (adults): Initial dose, 100 mg of Higrotona, twice a day. For maintenance dose, 50 mg per day is usually sufficient.
