Key takeaways You can take Zoloft in the morning or the evening, as long as it is at the same time each day. If Zoloft keeps you awake, a morning dose often helps; if it makes you sleepy, an evening dose often does. On r/zoloft, 40 people said they had moved their dose; 22 of them said how it went, and 21 of those said it helped. Change the hour gradually, not the dose, and call your prescriber sooner if sleep collapses or you feel wired and restless. On this page
When 143 people on r/zoloft take their dose Is it better to take Zoloft in the morning or at night? Should you take Zoloft at night if it makes you tired? Should you take Zoloft in the morning if it keeps you awake? How do you change the time you take Zoloft? What if you miss a dose of Zoloft? What should you tell your prescriber about timing and sleep? You can take Zoloft (sertraline) in the morning or at night. The NHS says to take it once a day at the same time, either in the morning or evening. Neither the NHS nor the FDA label names a better time, so the choice usually comes down to how it affects your sleep and energy.
When 143 people on r/zoloft take their dose
We read 78 recent threads about timing and sleep on r/zoloft, comments included, and 208 people described their own experience. These are people's own accounts, not trial data, and people who have trouble are more likely to post, so treat this as a range of experiences. Of the 208, 143 said when they take it, and they were split almost evenly: 74 take it in the morning and 61 in the evening or at night.
When they take it Of 143 people Morning 74 Evening or night 61 Afternoon 8
Of the 208, 40 said they had moved their dose: 21 from night to morning and 19 from morning to night. Of the 40 who moved it, 22 said whether the move made a difference, and 21 of them said it helped; the other 18 didn't say.
The reasons ran both ways. Among the 208, sleep trouble or vivid dreams came up for 29 people, and daytime sleepiness for 23. One person on r/zoloft wrote:
when I tried taking it in the mornings I was so sleepy throughout the day
Another had the opposite problem:
I took it at night because I saw it may cause drowsiness, but it did the opposite.
Is it better to take Zoloft in the morning or at night?
It depends on how it affects you, because Zoloft can cause both trouble sleeping and sleepiness. In the label's trials pooled across depression, OCD, panic disorder, PTSD, social anxiety and PMDD, 20% of adults on Zoloft had insomnia, against 13% on placebo, and 11% had sleepiness, against 6%. Levels peak about 4.5 to 8.4 hours after a dose, which is one reason some people notice it most at a particular time of day. If you notice either effect, ask your prescriber or pharmacist about trying the other time of day. Sleep changes are also among the Zoloft side effects women raise most .
Should you take Zoloft at night if it makes you tired?
For some people, yes. On Reddit, daytime sleepiness was a common reason people moved their dose to the evening, and of everyone who moved their dose either way and said how it went, 21 of 22 said it helped. Tiredness affected 12% of adults on Zoloft in the trials, against 8% on placebo. Ask your prescriber or pharmacist before you move it. The NHS says not to drive, ride a bike or use machinery if sertraline makes you dizzy or drowsy.
If tiredness stays heavy whatever the time, raise it with your prescriber. There are usually more options than the time of day, and which fits depends on you.
Should you take Zoloft in the morning if it keeps you awake?
Usually, yes. If you lie awake or have vivid dreams after an evening dose, a morning dose often eases it. Sleep problems are among the common side effects the NHS lists for sertraline, and many ease after a couple of weeks.
If sleep stays poor after a few weeks, tell your prescriber. Call sooner if sleep collapses suddenly, you feel wired and restless inside, or your mood drops, especially in the first weeks. Thoughts of suicide or self-harm need help right away; MedlinePlus notes the risk is higher in people under 24, in the first months and after a dose increase. In the US, call or text 988, or find a crisis line near you .
How do you change the time you take Zoloft? Clinical section: medical review pending
You change the hour, not the dose: shift the time a little each day over a few days until you reach the new time, then keep it; your pharmacist can help plan the steps. Sertraline has a half-life of about 26 hours, so it stays active between doses. The clinical view:
Taking your antidepressant at the same time each day matters more than the exact hour.
Pick the time by side effects. If a medication makes you drowsy, take it in the evening. If it keeps you awake or makes you feel wired, take it in the morning.
To change the time, move it gradually over a few days. Some antidepressants are better taken with food, which can also ease nausea.
What if you miss a dose of Zoloft?
The advice differs by country. The NHS says to skip the missed dose and take the next one the next day as usual. MedlinePlus says to take it when you remember, unless the next dose is nearly due. Both say never to take two doses to make up for one. Follow the advice of the country where you were prescribed it, and if you miss doses more than once, ask your pharmacist or prescriber what to do next time.
What should you tell your prescriber about timing and sleep?
Tell your prescriber when you take Zoloft and how your sleep and energy have been since starting, and ask whether a different time would suit you. It helps to tell them:
What time you take your dose, and whether you have moved it. How long it takes you to fall asleep, and whether you wake in the night. Whether you have vivid dreams or feel wired after a dose. How sleepy or tired you feel during the day. Any caffeine, alcohol or sleep aids you use. Download on the App Store Whether Zoloft keeps you up or makes you drowsy shows up over several days, not one. The withClaro app lets you log sleep, energy, mood and side effects each day, linked to your dose, and turns it into a report for your prescriber.
Frequently asked questions Can I take Zoloft with food? Yes. The NHS says you can take sertraline with or without food. Taking it with a meal can ease nausea in the first weeks.
Does taking Zoloft at night cause insomnia? It can for some people. Trouble sleeping is a common side effect. If an evening dose keeps you awake, ask your prescriber about switching to the morning.
Can I take Zoloft in the afternoon? Yes, if that suits you better; 8 people on r/zoloft said they do. Keep it at about the same time each day.
