Eye drops and eye ointments are familiar to us. However, their use is not as simple as people think, in daily life, due to the improper use of the two and the resulting bad things are heard from time to time. So, how to correctly and reasonably use eye drops and eye ointments? In the use, first of all, we should carefully read the instructions for the use of drugs, especially should pay attention to the indications and contraindications of drugs. Then, strictly follow the doctor’s instructions or instructions for use to apply reasonably. Eye drops and eye ointments need to pay attention to the following matters: 1. If the inner package of eye drops is composed of saline and drug powder (such as rifampin, etc.), it should be mixed and used by itself, otherwise it is just saline drops only. 2, because eye drops and eye ointment after opening the bottle directly exposed to the air, drops with eye contact inevitably cause contamination, so the first drop of drops and ointment need to be removed before dropping into the eye. 3, acute inflammation such as with a large amount of eye secretions, should be cleared secretions after the use of eye ointment. 4, eye inflammation when the local congestion is obvious, you can first hot compress, and then drops of eye ointment, the effect is better. For some allergic keratoconjunctivitis should be taken after cold or ice compresses, eye medication is appropriate after refrigeration. 5, eye drops, you can lightly pull down the eyelids, after exposing the fornix conjunctiva, the drops of medicine or ointment coated in the conjunctival sac, 1-2 drops of medicine each time, the ointment can be covered with the conjunctival sac. When dispensing, the mouth of the medicine bottle should be appropriately left from the affected eye to avoid touching the eyelashes and causing contamination, so that infection can occur in the uninfected eye due to the use of the same bottle of eye medicine. 6. Unopened drops and ointments should be stored in the refrigerator or in a cool place away from light. For eye medication that has passed its expiration date or the color of the medication has changed significantly, do not blindly use it. The ingredients within the eye medication have often changed and can cause inflammatory irritation or allergic reactions after drops are used. In recent years, various new drug formulations have emerged. While a large number of eye drugs are used, medical professionals are increasingly aware of the complications associated with various drugs.
