Hailey fe 1 20?

I can’t tell what you mean by “Hailey fe 1 20.” It could refer to different things (for example, a prescription drug name and strength, a contraceptive product, or a specific product code).

Tell me which one you’re asking about by adding one detail:
1) Is “Hailey Fe” a medication name? If yes, is it “Hailey Fe 1/20” (a birth-control pill)?
2) What do you want to know about it—uses, side effects, how to take it, whether it’s the same as another brand, or something else?

If it is the birth-control pill “Hailey Fe 1/20,” reply “yes” and I’ll explain what it is and what the “1/20” means.
