How can the bowel problems caused due to Gabapentin intake be managed?

Hi, my dr. Started me on Gabapentin to help control my migraines. I have been on it for 4 weeks now. I have IBS and have been having severe constipation since taking it. I take 100 mg twice a day. My concern is that my sensation to evacuate my bowels isn t there any more. I am due to see a neurologist next week but should I see someone before then?

Gabapentin can cause constipation as side effects. The prophylactic treatment of migraine includes also sodium valproate, topiramate, amitriptyline, nortriptyline, flunarizine, etc.

In case IBS-predominant constipation (IBS-C) is troublesome, switch over to alternative prophylactic drug for migraine may be tried.

Lubiprostone is a new class of compounds for treatment of chronic constipation with IBS.

You may seek the opinion of Gastroenterologist prior to Neurologist appointment.

Hope I have answered your query. Let me know if I can assist you further.

Take care
