What cold medicines can you take while on prednisone?

When taking prednisone, it's generally safe to use over-the-counter cold medicines that do not contain decongestants like pseudoephedrine, as they can increase blood pressure and cause other side effects. Antihistamines, such as diphenhydramine or loratadine, can be taken, but it's best to consult a healthcare provider for personalized advice. Additionally, avoid cold medicines containing alcohol or NSAIDs, as they may interact with prednisone. Always check with a doctor or pharmacist before combining medications.
