Amantadine HCl (Generic) Capsules
My 14 year old dog was having a lot of pain due to osteoarthritis. He has been steadily taking Carprofen. We have in addition tried Tramadol and Gabapentin. The Amantadine made a really big difference.
This medication works well in conjunction with his anti-inflammatory med. Have not noticed any of the possible side effects listed. At 13 years old he's doing pretty well.
