Zoloft Side Effects in Women: Sex Drive, Periods and What Passes
Most Zoloft side effects are the same for everyone, but sex drive and the menstrual cycle are where women often notice a difference. Here is what the label, studies and women on r/zoloft describe.

Medical review pending. Written by the Claro editorial team from the FDA label and published studies.
Key takeaways The FDA label doesn't split Zoloft's general side effects, such as nausea, diarrhea and trouble sleeping, by sex; only the sexual ones are counted separately for women. The FDA label notes that in women, SSRIs like Zoloft may lower sex drive and delay or block orgasm. In a 2012 study of 1,432 women, self-reported period problems were twice as common in the 793 taking antidepressants as in the 639 who were not. Mention side effects that bother you or do not go away; putting up with them and stopping are not the only options. On this page
What 75 women on r/zoloft said about side effects What are the most common side effects of Zoloft? Does Zoloft lower sex drive in women? Can Zoloft change your period? Which side effects pass, and when should you call your prescriber? What should you tell your prescriber about side effects? Zoloft (sertraline) side effects in women are mostly the same list as for everyone, since the label doesn't count most of them by sex. Two areas stand out for women: sexual side effects and changes around the menstrual cycle. Both are common, both are easy to put down to something else, and both are worth raising with your prescriber.
What 75 women on r/zoloft said about side effects
We read 100 recent threads on r/zoloft, comments included, about periods, PMS, sex drive and side effects, and 75 people wrote as women about their own experience on Zoloft. Of the 75, 56 named at least one side effect, and among those 56, changes around the cycle came up most: 23 women, ahead of sexual side effects at 14. We picked threads about women's experiences, and women who have no problems post less, so the numbers show what women talk about, not how often each side effect happens. One woman could name several:
What women described Of the 56 women who named one Changes to their period or PMS 23 Lower sex drive or trouble reaching orgasm 14 Tiredness 6 Sweating 5
Some women said their period itself changed, others that anxiety or low mood got worse in the days before it. One woman on r/zoloft wrote:
My first period while on Zoloft was the worst it had been in like a decade!
Sexual side effects were the second most common. Another woman described it this way:
I haven't had the desire for sex or even masturbation at all in the past few months
The other 19 of the 75 named none. One wrote:
No problems so far
What are the most common side effects of Zoloft?
Stomach upset and sleep changes top the list. In the FDA's pooled trials of adults, 26% of people on Zoloft had nausea, against 12% on placebo. Diarrhea affected 20% against 10%, and trouble sleeping 20% against 13%. These figures cover women and men together; the label doesn't give them separately, so there are no women-only numbers for nausea or sleep.
Other side effects more common than on placebo included sleepiness, tiredness, sweating and a smaller appetite. The NHS says most side effects ease after a couple of weeks, though some can last longer. If one bothers you, note when it started before you raise it. Weight change is one that tends to stay, as covered in Zoloft and weight gain .
If sleep or drowsiness is the problem, the time of day you take Zoloft can make a difference.
Does Zoloft lower sex drive in women?
It can. The FDA label says that in women, SSRIs may cause a lower sex drive and delayed or absent orgasm. In the label's trials, 4% of women on Zoloft reported a lower sex drive, against 2% on placebo.
That 4% is for lower sex drive only; the label gives no separate figure for delayed orgasm in women. Trial figures are probably low, because people rarely raise sex unless asked, and the label says the real rate is likely higher than it lists. For some women these effects last while they take Zoloft; there is little data on how long. If talking about sex with your prescriber feels hard, it can help to say one concrete thing, such as how long orgasm now takes or since when desire dropped, and ask what the options are. How another antidepressant compares is covered in Wellbutrin or Zoloft .
Can Zoloft change your period?
It can for some women. A 2012 study in Turkey of 1,432 women, 793 of them on antidepressants and 639 not, found self-reported period problems in 24.6% of those taking antidepressants, against 12.2% of those who were not. The authors judged that about 14.5% of the women on antidepressants had a period problem caused by the medication, though the women were on many different drugs and reported the problems themselves.
Sertraline was named among the drugs most linked to period changes in that study, but the paper gives no figure for sertraline on its own. Zoloft is also approved by the FDA to treat premenstrual dysphoric disorder (PMDD), the severe form of PMS. So the cycle can work both ways: some women find symptoms before their period ease, while others notice changes. Note which day of your cycle a symptom shows up. The label also notes that women on the pill were left out of the PMDD trials, so how Zoloft works for PMDD alongside oral contraceptives is unknown.
Which side effects pass, and when should you call your prescriber? Clinical section: medical review pending
Some side effects fade within weeks and some tend to stay, and a few need a call the same day. Knowing which is which helps you decide whether to wait or to speak up. The clinical view:
Most early side effects of antidepressants ease within the first weeks, while a few tend to last and are worth raising.
Side effects that often pass include nausea, an upset stomach, headache, sleep changes and feeling restless. Sexual side effects, weight change and feeling emotionally flat tend to stay while you take the medication. A change of dose or medication often helps with these, so mention them instead of putting up with them.
Call your prescriber the same day, or get urgent care, if you notice:
new or worse thoughts of suicide or self-harm, especially early on, after a dose change, or in young people agitation, heavy sweating, fever, muscle twitching or confusion, which can be signs of serotonin syndrome unusual bleeding or bruising a sudden burst of energy, little need for sleep, racing thoughts or unusual risk-taking What should you tell your prescriber about side effects?
Tell your prescriber which side effects you have, when they started and how much they affect your life, and ask what the options are for you. It helps to tell them:
Which side effects you have, and when each one started. Whether any of them rise and fall with your cycle, and on which days. Changes in sex drive or orgasm, even if they feel awkward to raise. Any change to your period: timing, flow or spotting. Any pregnancy plans, since that changes the conversation. If you have thoughts of suicide or self-harm, call your prescriber the same day. In the US, call or text 988, or find a crisis line near you .
Download on the App Store Some side effects on Zoloft come and go with your cycle, which makes them hard to describe at an appointment. The withClaro app lets you log mood, energy, sleep and side effects each day, linked to your dose, and turns it into a report for your prescriber.
Frequently asked questions How long should I wait before calling about a side effect? Raise anything that hasn't eased after a few weeks at the next appointment, and call the same day for the warning signs in the clinical view. Changes in sex drive or periods are worth raising whenever they bother you.
Does Zoloft decrease your appetite? It can, especially early on. In trials, 7% of adults on Zoloft reported a smaller appetite, against 2% on placebo. Tell your prescriber if your appetite has not come back after the first weeks.
Can Zoloft help with PMS? Zoloft is approved in the US to treat PMDD, the severe form of PMS. Some women also notice their mood before a period gets worse on it. Track symptoms by cycle day and share them with your prescriber.
Does Zoloft affect birth control? The Zoloft label doesn't list hormonal birth control among its interactions, but women on the pill were not included in its PMDD trials. If your cycle changes on Zoloft, mention it, since it can make it harder to tell what is causing what.
