If mixed with these,
Zoloft can cause serotonin syndrome. This includes fever,
sweating, muscle stiffness, trouble thinking clearly, a change in mental functioning, sleepiness, or change in your breathing, heartbeat and blood pressure disorder.
If this is the case, you should stop taking Zoloft and speak to your Doctor.
I can never emphasise enough, always insist medication comes with a leaflet which
states possible side effects.
