What eye drops to use for itchy eyelids?

Eye drops available for itchy eyelids are analysed as follows.
Itchy eyelids are generally more commonly caused by allergic factors and include antihistamines, mast cell stabilisers, complex anti-allergy preparations, glucocorticoids and non-steroidal anti-inflammatory drugs.
The main antihistamines are Emetine eye drops, mast cell stabilisers coloured glycolic acid sodium drops, compounded anti-allergy agents such as Pallotan eye drops and Pimecrolimus potassium eye drops all have anti-itch and anti-allergy effects, and non-steroidal anti-inflammatory drugs (pralophine eye drops) can also provide a degree of anti-itch relief.
More severe patients may consider using dexamethasone eye drops, but long-term use is not recommended, and it is important to be aware of the side effects of hormones.
