What are the many problems you're having? I'm on this drug. I've taken it since I had back surgery 3 years ago. I think it's making my back pain worse. Are you having back pain?

The half life calculator may be helpful in this case. You can also adjust the dosage or look up a different drug:

I understand that everyone has a different response to meds. This one is particularly symptom causing for me. Taken it for about 3 weeks. My levels of anxiety and depression have increased. I was prescribed it for a tough time detoxing from clonazepam. Stopping it over the next week. Only took 400 mg. per day.

According to the NIH, Gabapentin has an elimination half life or approx 7 hours on the high end. So for a single 300mg dose it would take 2 days or so for it to be fully metabolized. As far as consuming alcohol be aware that it could increase the effects of drowsiness which the drug can cause on its own so if you wanted to play it safe wait a couple of days after you have stopped taking the medication. But in the case of this drug, you should work with your doctor to discontinue use because as Verwon said, it needs to be done gradually instead of abruptly.

Hi! I am prescribed one pill of 300mg neurontin (gabapentin) in the morning and one in the evening. I’ve taken two pills since monday and have only been taking them for 3 days. The last pill I took was yesterday at 22:00. How long do I have to wait after my last pill before I can drink alcohol?

I'm not on gabapentin anymore. I took one 300 mg 3 months ago that my Dr told me to take for my nerve pain and m.s. But I took a drug panel on July 15th. And today is August 1st. It showed high levels. How can this be?

Verwon Says:
Hi, Sweet Pea! Sorry about the problems that it's causing you.
What types of symptoms have you been experiencing?
How long have you been taking it?
If you've been on it for awhile, at a high dose, suddenly stopping it could cause a risk of seizures, since it's an anticonvulsant. It is generally best to taper off of these types of medications.
Have you discussed it with your doctor?
