No there is essentially none. They both are brand name versions of the medication called levothyroxine. So this should not cause weight gain. However it is advisable to adhere to one brand as much as possible because subtle variations are possible. The most important thing is to check levels when switching brands or going to generic. The blood test result gives a true picture of the thyroid status.

I understand there are recently some availability problems with levoxyl.
