Sertraline - I have been on sertiline 50mg HCL for 9 days?

This is a serious side effect.

Call your doctor at once if you have:

a seizure (convulsions);
high levels of serotonin in the body - agitation, hallucinations, fever, """fast heart rate""", overactive reflexes, nausea, vomiting, diarrhea, loss of coordination, fainting;
low levels of sodium in the body - headache, confusion, slurred speech, severe weakness, vomiting, loss of coordination, feeling unsteady; or
manic episodes - racing thoughts, increased energy, unusual risk-taking behavior, extreme happiness, being irritable or talkative.

As it says inform you DR. asap, tomorrow morning.

All the best...
