No interaction documented between 5-HTP and Erythromycin. Always inform your healthcare provider about all supplements you take.
Space 5-HTP at least 1-2 hours from Erythromycin. Amino acids are best absorbed on an empty stomach. Follow the antibiotic's specific food instructions. Glutamine may help protect gut lining during antibiotic courses.
Higher risk for: those with liver or renal impairment, elderly, concurrent use of nephrotoxic or hepatotoxic drugs, history of C. difficile infection, or those on narrow therapeutic index medications (warfarin, digoxin).
Monitor for altered effectiveness and side effects when combining 5-HTP with Erythromycin. Antibiotics can affect liver enzymes and alter the blood levels of other medications. Watch for: unusual nausea, vomiting, diarrhea (especially watery or bloody), stomach cramps, skin rash, dizziness, or signs the other medication is working differently than usual. When to seek emergency help: Severe allergic reaction (difficulty breathing, swelling of face/throat, hives), severe or persistent diarrhea (possible C. difficile infection), yellowing of skin or eyes, dark urine, or irregular heartbeat. Complete the full antibiotic course as prescribed.
No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. Say: "I take 5-HTP and Erythromycin — is that OK?"
Safe combination at standard doses. Continue your medication as prescribed. Inform your doctor or pharmacist that you are using both, so they can monitor for any changes over time.
