My husband was started on gabapentin 100mg. three times a day, after a neurological event following taking Levaquin IV. It has been three months now since he was started on gabapentin. At first he had bad tremors, hand flapping, very weak legs, head ache. After about two weeks this got better. Now, his dosage has been increased to 200mg. three times a day. The side effects are even worse than before. Since we do not know of a real reason for him to take this, other than pain, we are thinking of tapering it off and stopping.
