What are the typical shelf-life conditions for opened eye drops?

The typical shelf-life condition for opened eye drops is 28 days. After opening, many eye drops are susceptible to contamination and degradation due to exposure to air and microorganisms. The 28-day guideline is a widely accepted standard that helps ensure the safety and efficacy of the medication during its use. This period allows for adequate time to use the product while minimizing the risk of potential adverse effects from an expired or contaminated product. Eye care specialists and pharmacists often recommend adhering to this timeframe, as beyond 28 days, the risk of infection and decreased effectiveness increases significantly.
