Does trithalmic ointment expire

Yes, trithalmic ointment, like most medications, does expire. The expiration date is typically printed on the packaging and indicates the date until which the ointment is guaranteed to be effective and safe to use. After this date, the potency and safety of the ointment may be compromised, so it's advisable to dispose of it and obtain a new prescription if needed. Always check with a healthcare professional if you're unsure about using an expired medication.
