Complete your full course of Erythromycin as prescribed alongside Propranolol. Some antibiotics can temporarily alter how other drugs are metabolized. If you experience unusual side effects during the antibiotic course, contact your prescriber.
Take each at their prescribed times. Most antibiotics don't significantly interact with beta-blockers, though macrolides (erythromycin, clarithromycin) can inhibit CYP3A4 metabolism of some beta-blockers like carvedilol, potentially increasing their effect. Monitor for dizziness or low heart rate.
Higher risk for: those with asthma or COPD, bradycardia, diabetes (may mask hypoglycemia symptoms), elderly, concurrent calcium channel blocker use, or peripheral vascular disease.
Monitor blood pressure and heart rate when combining Propranolol with Erythromycin. Watch for: dizziness, lightheadedness (especially when standing up), fatigue, cold extremities, slow heartbeat, or swelling in ankles/feet. Check your blood pressure at home if possible. When to seek emergency help: Fainting, chest pain, heart rate below 50 bpm, severe dizziness, difficulty breathing, or allergic reactions (swelling of face, lips, or tongue).
No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. Say: "I take Propranolol and Erythromycin — is that OK?"
These medications are safe to take together at standard doses. Continue taking as prescribed and keep your pharmacist informed of your complete medication list.
