Could Risperdal reduce the effects of concerta or other stimulants?

[EmirSahbaz]

I was taking a risperdal 4mg and Concerta.Just at the first day I took Concerta 54 mg,I was good enough.The other days,my sympyoms hasn’t decreased as I needed
.The concerta was a little effective but it was not enough.Then my doctor told me that risperdal may be reducing the concerta’s effects.Then I reduced Risperdal and Concerta’s effects were better.The second day wasn’t so good so I completely quitted Risperdal.Could risperdal reduce the effects of Concerta and If yes,If I quit ,due to it did not leave my system yet,does it proceed repressing it’s effect?

These are ultimately questions for your doctor, but you are right that there can be an interaction between medications that reduces the effect of one or both of the medications. Sometimes, changing what time of day you take one can help, sometimes, the combination just doesn’t work if you have this issue.
