When considering whether to reuse your opened Betoact Eye Drops (Bepotastine 1.5%), here are some important points:

• Check the expiry and storage: Eye drops usually have a recommended usage period after opening, often 4 weeks, to avoid contamination. Since your bottle has been open for two months, it may no longer be safe.

• Risk of infection: Using eye drops beyond the recommended period can increase the risk of eye infections.

• Effectiveness: The medication might lose potency over time once opened.

• Recommendation: It is generally safer to purchase a new bottle for your relapse to ensure safety and effectiveness.

If symptoms persist or worsen, please consult your eye specialist for proper evaluation and treatment guidance.
