Aristo Hydrochlorothiazide 25 mg is a medication that contains hydrochlorothiazide as the active ingredient. Hydrochlorothiazide is a diuretic (a medication that increases the elimination of urine) that belongs to the group of thiazides. Hydrochlorothiazide increases the amount of urine (diuretic) helping to reduce blood pressure (antihypertensive).
This medication is indicated for the treatment of the following diseases:
- high blood pressure (elevated blood pressure) alone or in combination with other antihypertensive medications,
- edema (excessive retention of fluid in tissues) due to heart, kidney or liver disease,
- prevention of the formation of urinary stones (stones in the urinary system) in patients with elevated levels of calcium in urine,
- nephrogenic 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) when treatment with antidiuretic hormone is not indicated.
- If you are allergic to hydrochlorothiazide or any of the other components of this medication (listed in section 6),
- If you have problems eliminating urine (anuria),
- If you are pregnant and have high blood pressure,
Warnings and Precautions
Consult your doctor or pharmacist before starting to take this medication.
Be especially careful in the following situations:
- If you have kidney problems,
- If you have liver problems,
- If you have electrolyte imbalances, such as high levels of calcium in the blood,
- If you have metabolic and endocrine problems,
- If you have a systemic autoimmune disease called systemic lupus erythematosus,
- If you experience a decrease in vision or eye pain, it could be a symptom of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased eye pressure, and can occur within a few hours to a week after taking hydrochlorothiazide Aristo. If left untreated, it can lead to permanent vision loss. If you have had a previous allergy to penicillin or sulfonamide, you may be at higher risk of developing it,
- If you have allergies or asthma.
- If you have had respiratory or pulmonary problems (such as inflammation or fluid in the lungs) after taking hydrochlorothiazide in the past. If you experience severe shortness of breath or difficulty breathing after taking hydrochlorothiazide Aristo, seek medical attention immediately.
- If you have had skin cancer or if an unexpected skin lesion appears during treatment. The treatment with hydrochlorothiazide, particularly long-term use at high doses, may increase the risk of certain types of skin and lip cancer (non-melanoma skin cancer). Protect your skin from sun exposure and UV rays while taking hydrochlorothiazide.
