I have a horrible head cold with sinus pain and pressure and a stuffy nose. No chest congestion or cough. What is safe to take? I know avoiding pseudoephedrine because it can decrease milk supply, but what about phenylephrine? It is a decongestant, so is there the same risk as pseudoephedrine? I have been using a nasal spray with oxymetazoline and it has provided some relief, but it doesn't last as long as it says and I don't want to take it too much longer because of rebound congestion.
