Does generic of synthroid (levothyroxine) disperse the dosage equally throughout pill. i'm on 75mcg so if i cut in half will i get 37.5mcg?

Generic: It's equally distributed, so you can get 37.5 mcg if you cut it in half. It is the actual dose of the medical that may differ from the stated in some generics.

It's not the: Cutting in half that's a problem, as even if the cut is uneven it won't matter since the half-life of T4 is 7 days and the doses will overlap. The problem is that the generics aren't as reliable and the dose and potency will vary every time you get a new prescription, or the pharmacy changes suppliers, or with age and storage of the rx, etc. It is better and safer to stick w/brand name t4.
