I am taking 10 mills. of Neurontin, 20 mills. of Paxil, & 25 mills. of Hydrodiuril, they all have different names about these names and say they are substitutes for these drugs. The Hydrodiuril is a sub. for H.C.T.Z and Neurontin is a sub. for Gabapentin, so am I really taking 100 mg. of Gab. instead of Neurontin? What do I call my medications? And Paxil is Paroxetine. The sub. names are highlighted in yellow by the pharmacist. I've been calling them by the substitute names and nobody is confused when I use those names but I'm still confused about it.
