Hello and welcome to HCM
It is not advicable to change or stop your medication on your own.
Your treating doctor knows what is best for you so trust your treating doctor.
Rexipra which you were taking previously was an anti-anxiety
Paxidep ic an anti depressant
The two drugs belong to different category and have different actions. So, one is not a substitute for the other.
Paxidep does not cause weight gain, so relax.
There are different classes of anti depressants like tricyclic anti depressants and selective serotonin reuptake inhibitors (SSRI
Tricyclic anti depressants cause weight gain but the SSRI group does not have this side effect.
Paxidep belongs to SSRI group so no weight gain.
Thanks and take care
