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 medicine.

You should inform your doctor if you are pregnant or suspect you are pregnant.

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 human milk, so its use is not recommended in breastfeeding mothers.

Athletes are informed that this medicine contains a component that may result in a positive doping test.
