What is a one-sentence summary of the following article?
One of the possible side effects of Zoloft is jitters and nervous energy. These feelings can especially take place when you are in the process of increasing your dosage. That is why they are referred to as “treatment emergent.” If you experience these side effects, reach out to your doctor as soon as possible.  Agitation encompasses everything from being unable to sit still to repeating the same thoughts in your head over and over again. Other possible side effects of Zoloft include sweating, tremors, insomnia, tiredness, heart palpitations, dizziness, or worsening of depression symptoms. It can sometimes take weeks for your symptoms to improve as a result of Zoloft. Try your best to be patient and communicate any concerns to your doctor during this period. Stopping your medication suddenly can cause severe illness and withdrawal symptoms. If you miss a dose of Zoloft, do not double-up with your next dose. Instead, just consider it missed and continue with your regular dosage schedule. As you change your Zoloft dosage, it’s possible that your body might react. If you experience a seizure, blurred vision, severe headaches, or vomiting, reach out for emergency assistance and call your doctor as well. These can all be symptoms of serotonin syndrome, which is essentially a sign of too much Zoloft in your system. You might also feel unsteady on your feet or experience a loss of coordination. Do not drive if you start to manifest these symptoms.

Summary:
Watch out for signs of agitation. Do not stop using Zoloft without talking to your doctor. Seek medical attention right away if you experience extreme symptoms.
