I was recently prescribed Topamax 25 mg at bedtime. I also take Neurontin and the Topamax is an addition. I'm sure the plan is to increase it.
I did not have many side effects with the Neurontin but do have some with Topamax- mostly tingling and tiredness. I cannot imagine if I were to take it in the morning. I have not noticed any pain reduction but then the dosage is still very low. It is not uncommon to prescribe Topamax with Neurontin for neuropathy. Hope it works for you. (and for me too!0
