It is important to know that, after opening of the drug container the expiring date actually becomes shorter, this is because of external factors and decreased concentration as the drug is under usage.
Eye drops should be used within those periods because with usage the concentration is decreased so therefore creating more room for contamination with usage as such to get the best from your eye drops, used it within a month.
Ampoules is for injection, it should be checked whether it is cracked or leaking in anyway. If so, it shouldn’t be used as it might have been contaminated giving that it is to be injected directly into the blood stream.
