Regarding your medications: the paracetamol in Cyclopam and most common toothache antibiotics are generally safe while breastfeeding. However, Cyclopam also contains dicyclomine, which can sometimes reduce your milk supply and is best used with caution. 'Gag R' (typically a local rinse) is generally safe as very little is absorbed into your body. To keep your baby completely safe, please share the exact name of your prescribed antibiotic with your doctor or pediatrician before your next feed. They can easily confirm if a brief pause in breastfeeding is needed.
