Intranasal corticosteroids (budesonide/Rhinocort, fluticasone/Flonase/Sensimist, mometasone/Nasonex) are all considered compatible with breastfeeding at intranasal doses, per LactMed. Azelastine has limited lactation data but is generally considered acceptable due to low systemic absorption. Saline is drug-free and always safe. Discuss individual cases with your pediatrician.",

Consensus guidelines specifically endorse saline irrigation for rhinitis of pregnancy (Rabago 2009) Intranasal cromolyn sodium has a long-standing favorable safety record and minimal systemic absorption (Ratner 2002); per LactMed, cromolyn is generally considered acceptable during pregnancy and lactation when symptoms warrant pharmacotherapy, especially as a non-steroid adjunct Allermi is not currently prescribed during pregnancy or breastfeeding\n\n## Allermi while breastfeeding\n\nAllermi is not currently prescribed to patients who are breastfeeding. Talk to your OB/GYN or pediatrician about medication choice during lactation. If you want to confirm eligibility for after you wean, [check eligibility in 60 seconds](https://www.allermi.com/pages/eligibility).\n\n## Practical picks\n\nSteroid options that LactMed lists compatible at intranasal doses: [Rhinocort (budesonide)](/reviews/rhinocort/), [Flonase (fluticasone propionate)](/reviews/flonase/), [Sensimist (fluticasone furoate)](/reviews/sensimist/), and [Nasonex (mometasone)](/reviews/nasonex/). Rhinocort carries forward its [pregnancy-first-line](/demographic/pregnancy/) status into postpartum for consistency. For a non-steroid route, [NasalCrom (cromolyn)](/reviews/nasalcrom/) has the longest lactation-safety track record. For [chronic congestion](/symptom/congestion/) picks filtered for lactation, start with the same top-tier INCS list.\n\n",
