Safety advice for Megapen 500 mg Injection Vial

Warnings and precautions

Finish the whole course even after you feel better. Stopping early lets the strongest bacteria survive, and they are the ones that come back resistant. Stop and seek emergency care for swelling of the face or throat, difficulty breathing, or a widespread rash — a penicillin allergy can be serious. Tell every doctor and pharmacist if you have ever reacted to penicillin. Tell your doctor if loose motions become severe or watery, or continue after the course — this needs attention rather than an anti-diarrhoeal. Antibiotics do not work against colds, flu or most sore throats, which are caused by viruses.

Do not take Megapen if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for anyone with a known penicillin allergy.

Interactions with other medicines

May reduce the reliability of the oral contraceptive pill if you have vomiting or loose motions — use additional precautions during the course. Tell your doctor if you take methotrexate or a blood thinner.
