Hamare expert ka khayal (Verdict)

Both are first-line SSRIs. Zoloft (Sertraline) is often the first try in Pakistan because of broad evidence and good tolerability. Prozac (Fluoxetine) is convenient if missed doses are likely (long half-life forgives missed days) and is preferred in adolescents. SSRIs must be prescribed and monitored by a doctor — do not start, stop, or switch on your own.
