Not medical advice: There is no pill imprinted with GC 101, but there is a white capsule-shaped pill inscribed with GG 101 instead. The prescription-only drug is 750 mg of the muscle relaxant Methocarbamol and is used to treat tetanus, opiate withdrawal, and muscle spasm. Skelex, Carbacot, Robaxin, and Robaxin-750 are brand names.
Less serious side effects reported include stuffy nose, insomnia, mild itching or rash, upset stomach, nausea, vomiting, headache, dizziness, and drowsiness. Call your doctor immediately if you experience seizures, jaundice, a slow heart rate, flu-like symptoms, or feel like you might faint.
Despite research showing that Methocarbamol is non-habit forming there are still reports of people attempting to abuse it. A Florida man recently arrested and charged with DUI said that the two Methocarbamol pills in his possession were won during a game of pool.
