months of your pregnancy.

effects on your new born baby.
It is unknown whether Primalan is excreted in human
breast milk. As it is not known whether this is harmful
to your baby, this should be discussed with your doctor

As Primalan can make you drowsy, your level of
alertness may be impaired making driving or machine
use dangerous. The drowsiness associated with the use
of this medicine is increased by the consumption of
alcoholic drinks, other medicines which contain alcohol
