i would like to find out the side effects of inderal, i take 10mg once in the morning. i started having panick attacks, but did not know this, my GP did some tests and showed irregular heart beat, hence the inderal. in the interim i have been diagnosed by a psychiatrist as having panic attacks. i was also diagnosed with bi-polar (not manic) and suffer from depression. i have been prescribed 100mg of neurontin 3 times a day, lamictan 100mg at night, remeron 30mg at night, what are the interactions of all these medications? i have also put on a lot of weight but does not know which of these medications are the cause of the weight gain?
