What is the difference between USP and HCL? I have been taking the bupropion hydrochloride extended release USP (XL) for years. I picked up my script and this one is labeled bupropion HCL Extended release XL. Totally different bottle. Totally different looking pill. My dosage has not changed. Is this okay to take? Is it the same?
Hi, Caraigh! There is no difference. HCl simply means hydrochloride which is the chemical formulation of bupropion. All generics will look different as they are made by different manufacturers.
