Key takeaways
Triamcinolone (Nasacort) and brompheniramine/phenylephrine (Dimetapp Cold and Allergy) are both medications used to treat allergy symptoms, such as nasal congestion and runny nose. However, they belong to different medication classes and have important differences. Triamcinolone is a corticosteroid nasal spray that reduces inflammation in the nose, while brompheniramine/phenylephrine is an oral combination of an antihistamine and a decongestant. Nasacort is used once daily and is available over-the-counter as both a brand-name and generic product. In contrast, Dimetapp Cold and Allergy is taken every 4 hours and is also available over-the-counter, as a liquid and tablet. Common side effects of Nasacort include sore throat and nosebleeds, whereas Dimetapp can cause dizziness and sleepiness. Additionally, Nasacort is generally safe for those with high blood pressure, while Dimetapp may worsen conditions like heart problems or high blood pressure.
