The action of Domperidone on gastro-intestinal function may be antagonized by antimuscarinics and opoid analgesics. Care should be exercised when Domperidone is administered in combination with MAO (monoamine oxidase) inhibitors.

It is contraindicated in patients with known hypersensitivity to Domperidone or any components of the preparation. Domperidone should not be used whenever gastro-intestinal stimulation might be dangerous (i.e., gastro-intestinal hemorrhage, mechanical obstruction or perforation). It is also contraindicated in prolactinoma.

It may produce hyperprolactinemia (1.3%). This may result in galactorrhea, breast enlargement & soreness and reduced libido. Dry mouth (1.9%), thirst, headache (1.2%), nervousness, drowsiness (0.4%), diarrhea (0.2%), skin rash and itching (0.1%) may occur during treatment with Domperidone. Extra-pyramidal reactions are seen in 0.05% of patients in clinical studies.

The safety of use of Domperidone has not been proven duing pregnancy; it is therefore not recommended during pregnancy. Animal studies have not demonstrated teratogenic effects on the fetus. Domperidone may precipitate galactorrhea and improve post-natal lactation. It is secreted in breast milk in very small quantities which is insufficient to be considered harmful.

It should be used with absolute caution in case of children because there may be increased risk of extra-pyramidal reactions. Since Domperidone is highly metabolized in liver, it should be used with caution in patient with hepatic impairment.

Keep in a dry place away from light and heat. Keep out of the reach of children.
