Lioresal tablet. I take half a tablet twice a day. I dont know if its 5mg or 10mg. It is a small round white tablet with K on one side and G on the back ## I cannot find a listing for this, I tried adjusting the imprint and even looking under logos. Lioresal contains Baclofen, it is primarily used as a kind of muscle relaxant to treat spasms, so it is only available in the U.S. by prescription. Do you not have a prescription bottle? Does anyone else have information on this?
