What other drugs will affect Neurontin?
Neurontin does not interact with other commonly used antiseizure medications. Antacids will decrease the amount of Neurontin that is absorbed in the stomach. Do not take Neurontin for at least 2 hours after a dose of antacid. Neurontin may increase the effects of other drugs that cause drowsiness, including antidepressants, alcohol, antihistamines, sedatives (used to treat insomnia), pain relievers, anxiety medicines, and muscle relaxants.
