Moderately safe. Probably compatible.
Mild risk possible. Follow up recommended.
Read the Comment.

First generation antihistamine with sedative and important antimuscarinic effects. Such remarkable anticholinergic effect may inhibit lactation.

At latest update no published data on excretion into breast milk were found.

Drug with poor scientific support which is marketed in very few countries.
Marketed as part of in many “at the counter” compounds in association poliasociación with expectorants, bronchodilators, antitussives, etc. Avoid the use of drug associations mostly while breastfeeding.

Although occasional and moderate use during lactation would probably not pose a serious risk, a safer alternative should be preferred until more data on this drug related to breastfeeding is available.

Topically used on the skin, it would not represent a risk during breastfeeding. Avoid applying it on the breast.

Assess the child for drowsiness and inappropriate infant feeding.
It is not recommended bed-sharing with your baby if you are on this medication.
