How Long Can I Safely Use Naphcon A Drops for my Droopy Eyelid After Receiving Dysport?

Naphcon, or any other drop that "gets the red out", is NOT to be used for more than 4-5 days. These drops are vasoconstrictors [shrink blood vessels], and your eye will eventually develop tolerance to them, so that if you don't use the drops, your eyes will ALWAYS be red.

Ideally, to combat the temporary droopy eyelid after botox or dysport, apraclonidine [Iopidine] eye drops are prescribed. These don't have the same whitening effect on the eye, though prolonged use will cause irritation.

Only use the drop for special occasions, and be patient as the Dysport effect wears off.

Yes, the effects of the drops only last for a few hours. The idea is that you should put them in every 3-4 hours, and up to 4x per day, because those are the hours you'd be awake. Most cases of droopy eyelids can take a few weeks to resolve, as the muscles start to re-tighten again and lift on their own. I've never told people to only use the drops for 4 days, and I'm unsure why the NaphconA packaging would say that.... But in my opinion you can use them 4x per day, for however long you need.
