Is there a safe decongestant medication for breastfeeding (e.g. Tylenol Cold and Sinus)?

Yes, there are safe decongestant medications for breastfeeding. Oral decongestants containing pseudoephedrine, such as those found in Tylenol sinus or Advil sinus, are considered safe for breastfeeding mothers. However, they may slightly decrease milk production. If you prefer a decongestant that won't affect your milk supply, you can opt for a nasal spray decongestant like Drixoral or Otrivin. It's important not to use nasal decongestants for more than 7 days to avoid rebound congestion. If you have congestion, nasal irrigation with a product like Sinus rinse may also help.
