• if you have electrolyte imbalance, such as high calcium levels in the blood,
• if you have metabolic and endocrine disorders,
• if you have an autoimmune disease called systemic lupus erythematosus,

Treatment with hydrochlorothiazide, particularly long-term use at high doses, may increase the risk of certain types of skin cancer and lip cancer (non-melanoma skin cancer). Protect your skin from sun and UV radiation while taking hydrochlorothiazide.

Taking Hydrochlorothiazide Aristo with Food, Drinks, and Alcohol

Pregnancy, Breastfeeding, and Fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Generally, your doctor will advise you to take a different medication instead of Hydrochlorothiazide Aristo 25 mg, as hydrochlorothiazide is not recommended during pregnancy. This is because hydrochlorothiazide crosses the placenta, and its use after the first trimester of pregnancy may cause potentially harmful effects on the fetus and newborn.

Hydrochlorothiazide is excreted in breast milk, so its use is not recommended in breastfeeding mothers.

No human data are available. Animal studies do not show effects on fertility.

Driving and Using Machines

It is unlikely that hydrochlorothiazide will affect your ability to drive or use machines.

Hydrochlorothiazide Aristo Contains Lactose

If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.

Use in Athletes
