If you mean Levoxyl:
Generic Name - Levothyroxine - contains the same active ingredient as brand-name Synthroid and Levoxyl.
Chemical Name - active ingredient is synthetic crystalline L-3,3',5,5'-tetraiodothyronine sodium salt (Levothyroxine (T4) sodium).
Classification - T-4
Contraindications - Administration (FDA) has determined that generic levothyroxine and brand-name Synthroid and Levoxyl are equivalent. The FDA requires all drugs—both brand-names and their generic counterparts—to be proven safe and effective. Since generics use the same active ingredients and are shown to work the same way in the body as their brand-name counterparts, they also have the same risks and benefits.
