Is it Safe to Take Expired Flagyl?
I have Flagyl and it expired on 2/03/09. Can I still take this? I took one already when I noticed it was expired. Is it fatal or does the medicine lose its potency?
Flagyl is a brand name for the drug metronidazole. The expiration dates on drugs such as Flagyl ensure the strength of the drug. Using an expired drug is unlikely to cause harm but the drug may not work for the intended purpose. Solid dosage forms, including tablets and capsules, are affected by light, moisture, and temperature. Improper storage can cause the drug to lose potency.
Talk to your pharmacist about any other concerns regarding the Flagyl prescription.
