Hi Jack I'm seeing a client who has been having sinus and ear congestion since 7th mo. of pregnancy, and it continues- her babe is 10 days old. The paediatrician said she should not use Chlortriplon (the regular one-not decongestant) even though our MotherRisk clinic said it was ok. I think Hale's book also said it was ok. She would like to use it. In the meantime she has been using Otrivin paediatric strength for herself. She's afraid to use adult strength because of possible rebound effect. This is all complicated by the fact that she's new to Ottawa, and is not properly established with a doc she likes. Can you comment on the Chlortripolon and Otrivin? How often and how long can she take the Otrivin without it causing rebound? Is adult strength ok? She also had started a series of allergy desensitization and stopped during her pregnancy and would like to resume. Is allergy desensitization compatible with breastfeeding?
