Against indications

This medicine is contraindicated in the following situations:
- hypersensitivity to acetazolamide,
- severe hepatic, renal or adrenal insufficiency,
- intolerance to sulphonamides,
- history of renal colic.
This drug is generally not recommended during pregnancy and lactation:
- pregnancy: studies in animals have shown a teratogenic effect. In clinical practice, the use of acetazolamide sodium in a limited number of pregnancies has not revealed any particular malformative or foetotoxic effect to date. However, further studies are needed to assess the consequences of exposure during pregnancy. Given the indication and the absence of alternatives, intravenous acetazolamide may be used, if necessary, during pregnancy.
- breastfeeding: given the passage of acetazolamide in milk, breastfeeding is not recommended.
