how can i get pk-merz amantadine tablets 100mg. here in the united states. i have been taking amantadine for my multiple sclerosis symptoms (Weakness) for over 15 years. i lost my job and am no longer able to get perscriptions or medications because i lost my medical insurance. at first, the price of amantadine was more or less afordable without medical insurance, but the price skyrocketed all of a sudden way out of my possibilities. pk-merz amantadine, however, is still at a reasonable price.
