The drug you have mentioned here are-
2. OLYEANZ- OLANZAPINE
3. PAXIDEP CR- PAROXETIN
Now ESCITALOPRAM & PAROXETIN is ANTI DEPRRASANT
OLANZAPINE- Atypical Anti Psychotic
CLONAZEPAM- Sedative , Anxiolytic.
Side Effects Rellated To Sexual Potency:
PAROXETIN- Delayed or impaired ejaculation.
ESCITALOPRAM- Loss of Orgasm during Sex.
Olanzapine and Clonazepam is quite safe in this matter.
Now several new drugs such as MIRTAZAPINE
etc are devoid of these side effects.
So I think you should take a second opinion
. Because Both NEXITO & PAXIDEP have some side effects regarding this.
