Quick Answer: Zoloft (sertraline) is an SSRI antidepressant that can cause nausea, diarrhea, headache, sleep changes, sweating, dizziness, and sexual side effects. Some effects improve as the body adjusts during the first few weeks, while severe, persistent, or unusual symptoms should be discussed with a medical professional.
At Saltwood Mental Health, we help adults understand medication within the larger context of their mental health, symptoms, and daily functioning.
If you’re struggling with side effects or wondering whether your current treatment is working, contact our team to learn how we can help.
What Is Zoloft, and How Does It Work?
Zoloft is the brand name for sertraline, a selective serotonin reuptake inhibitor (SSRI) prescribed for several mental health conditions. It is FDA-approved for these conditions:
- Major depressive disorder
- Obsessive-compulsive disorder
- Panic disorder
- PTSD
- Social anxiety disorder
Sertraline influences serotonin activity in the brain. Benefits may develop gradually, so it can take several weeks to determine how well the medication is working.
What Are the Most Common Zoloft Side Effects?
The most common Zoloft side effects include gastrointestinal symptoms, sleep changes, sweating, and sexual difficulties. Nausea, diarrhea, decreased appetite, tremor, and increased sweating are among the effects reported with sertraline.
Other people may experience headaches, dizziness, fatigue, drowsiness, insomnia, dry mouth, or restlessness. The type and severity of side effects can vary considerably from person to person.
What Side Effects Should You Expect During the First Few Weeks of Taking Zoloft?
Wondering about the Zoloft side effects the first week might bring? It is true that side effects can be more noticeable when first starting Zoloft or after a dosage adjustment. However, some early symptoms may improve as your body becomes accustomed to the medication.
Mental health symptoms may take longer to improve than initial side effects take to appear. We encourage patients to communicate with their prescribing provider rather than stopping, skipping, or changing doses independently.
How Side Effects of Zoloft Can Differ for Men and Women
Zoloft can cause sexual side effects in both men and women, but the specific effects may differ. The prescribing information reports decreased libido, difficulty with ejaculation, erectile dysfunction, and other sexual dysfunction among men, while Zoloft side effects in women include decreased libido.
Women may also experience delayed orgasm or difficulty reaching orgasm, while side effects of Zoloft in men may include delayed or absent ejaculation or difficulty getting or maintaining an erection. These effects shouldn’t be ignored simply because they can be uncomfortable to discuss.
Outside of sexual side effects, there is significant individual variation. Your symptoms, dosage, other medications, hormonal factors, health history, and the condition being treated can all influence how Zoloft affects you.
Can Zoloft Affect Sleep, Weight, and Appetite?
Zoloft can affect sleep, appetite, and energy levels, although not everyone experiences these changes. Some people feel drowsy while others develop insomnia or restlessness.
Changes in appetite can also occur and may contribute to weight changes over time. Significant or unexplained changes should be discussed with your provider.
When Are Zoloft Side Effects Serious?
Certain Zoloft side effects require prompt medical attention. Serious concerns can include serotonin syndrome, abnormal bleeding, seizures, mania, severe allergic reactions, or dangerously low sodium levels.
Seek immediate help for symptoms such as severe confusion, high fever, marked agitation, seizures, loss of consciousness, or thoughts of suicide or self-harm. Antidepressants also carry a boxed warning concerning increased suicidal thoughts and behaviors in pediatric and young adult patients, particularly during early treatment or dosage changes.
Anyone experiencing an immediate risk of self-harm or severe symptoms should call 911 or seek emergency medical care.
What Happens If You Stop Zoloft Suddenly?
Stopping Zoloft abruptly can cause discontinuation symptoms. These may include dizziness, irritability, anxiety, nausea, headache, sweating, sleep problems, mood changes, and unusual tingling sensations.
A prescribing clinician may recommend gradually reducing the dose when discontinuation is appropriate. Do not stop taking Zoloft without first discussing it with your provider.
