A combination is a different drug — different dosing, different warnings. It is listed here so you can find it, not so you can substitute it.
Polythiazide and breastfeeding

Full LactMed record for polythiazide: levels in milk, effects in breastfed infants, and the drugs it would consider insteadNo information is available on the amount of polythiazide in breastmilk. Intense diuresis with large doses may decrease breastmilk production. Other diuretics in low doses are preferred over polythiazide.

Frequently asked questions
Can you take polythiazide with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run polythiazide against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does polythiazide come in?
Across the brands we track, polythiazide is currently marketed as tablet, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic polythiazide?
We do not currently list a generic-labelled polythiazide product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
