Hi, Perinorm is a brand name for the medication metoclopramide, which is used to increase milk production in breastfeeding mothers. It works by stimulating the release of prolactin, a hormone that is necessary for milk production. Some potential side effects of metoclopramide can occur in both the mother and the baby. These side effects include drowsiness, restlessness, irritability, diarrhea, and nausea. Rarely, it can also cause depression and movement disorders such as tardive dyskinesia. While it is generally considered safe to take metoclopramide while breastfeeding, it is important to talk to your healthcare provider about any concerns you may have. They can help you weigh the potential benefits against the risks and help you make an informed decision. In terms of how long you can continue taking the medication, that is also something you should discuss with your healthcare provider. In general, metoclopramide is recommended for short-term use (up to 12 weeks), but your provider may recommend a different duration based on your specific situation. It s important to note that medication alone may not be enough to increase milk production and that breastfeeding often works on a supply-and-demand basis. Your body will produce more breast milk if you feed more often. So it s important to continue to breastfeed as often as possible and to seek support from a lactation consultant or breastfeeding support group if needed. Take care.
