If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Fertility

Melatonin Hard Capsules are not recommended in women and men planning to have a baby as there is insufficient information on the effects of melatonin on female and male fertility.
