My doctor has prescribed me zoloft 50mg. just completed one week but the past 3 nights i've had a lot of trouble sleeping. would it be from the medication or for my anxiety? it was happening before i started the meds but not as bad or as frequent.

And: It is possible to be from the Zoloft (sertraline). You could try to take the medication in the am and see if this helps. You gave not been on the medication very long. Speak to your doctor again

Zoloft (sertraline) affects sleep: Zoloft (sertraline) can certainly cause trouble sleeping at first. This tends to get better with time. You may also notice vivid dreams (not necessarily bad ones). If this persists after the first week or is too uncomfortable, call your doc to see if any adjustment in dose may be in order. This often resolves during the first month, in many.

Zoloft (sertraline) and sleep: Not sure what you mean by "trouble sleeping." Do you mean trouble falling asleep, tossing/turning etc? What exactly is worse? Could be anxiety, timing of when you take Zoloft (sertraline) dose, other meds interacting, sensitivity to med. Try keeping a sleep log: https://sleepfoundation.org/sleep-diary/SleepDiaryv6.pdf and discuss with prescribing doctor. I hope this helps. Best wishes.
