Yes. Antidepressants can cause nausea, especially when someone first starts taking them or after a dose change. Feeling sick or occasionally vomiting is a known side effect of several antidepressants, including selective serotonin reuptake inhibitors (SSRIs). For many people, nausea eases as the body adjusts over the next couple of weeks, but it can last longer. Persistent or disruptive symptoms deserve a discussion with the prescriber.
Why can antidepressants cause nausea?
Antidepressants affect chemical messengers involved in mood and other bodily functions. Nausea and vomiting are among their recognized side effects, although not everyone experiences them. The exact side effects depend on the medication, its dose, and individual circumstances.
According to MedlinePlus, common side effects of antidepressants include nausea, vomiting, diarrhea, sleepiness, and sexual problems. These effects may improve as the body gets used to the medicine. If they become difficult to manage, a healthcare professional can help determine whether changes to the treatment are appropriate.
Which antidepressants can cause nausea?
Nausea can occur with several types of antidepressants. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are commonly prescribed groups that may cause digestive side effects. Older antidepressants can have different side-effect profiles, too.
The NHS explains that antidepressant side effects vary by medication. For example, nausea and vomiting are listed among the common side effects of sertraline, an SSRI. Other antidepressants may affect people differently, so the information provided with the specific prescription is the best starting point for understanding its known side effects.
When does nausea start, and how long does it last?
Nausea often begins early in treatment, sometimes during the first few days after starting an antidepressant. It may also be noticed after a change in treatment, although the timing alone cannot establish that the medicine is responsible.
For many people, nausea improves within a few weeks as the body adjusts. The Mayo Clinic notes that nausea commonly begins early and may settle as the body adjusts to an antidepressant. However, improvement is not guaranteed, and some people continue to experience troublesome side effects. Nausea that persists, worsens, or interferes with normal activities should be discussed with the prescribing clinician.
How can you reduce nausea while taking antidepressants?
Several practical steps may help make medication-related nausea easier to manage. The right approach depends on the specific antidepressant and its instructions.
- Check whether you can take the medicine with food. Taking an antidepressant with food may help, but follow the instructions supplied with your prescription or ask a pharmacist if you are unsure.
- Eat smaller, more frequent meals. Smaller portions throughout the day may be easier to tolerate than a few large meals.
- Drink fluids regularly. Sip water throughout the day, particularly if nausea makes eating and drinking less comfortable.
- Keep track of symptoms. Note when nausea occurs, when you take your medicine, and whether the symptoms are improving. This information may help your prescriber assess the situation.
- Review other medicines and supplements. Tell your healthcare professional about prescription medicines, over-the-counter products, vitamins, and herbal supplements you use. Ask before adding a medicine for nausea, because some products may interact with your antidepressant.
These measures may provide relief, but persistent nausea should not be managed indefinitely without advice. Your clinician can review whether the current treatment remains suitable and whether another approach may be needed.
Should you stop taking an antidepressant if you feel nauseated?
Do not stop taking an antidepressant suddenly or change your dose on your own because of nausea. Stopping abruptly can cause withdrawal symptoms, including nausea, dizziness, and other uncomfortable effects. It may also interfere with the treatment plan for the condition being treated.
If nausea is difficult to tolerate, contact your prescriber. Depending on the medication and your circumstances, they may consider adjusting the dose, changing when you take it, switching to another antidepressant, or exploring another way to manage the side effect. The aim is to address the discomfort while maintaining an appropriate treatment plan.
When should you seek medical attention?
Contact your healthcare professional if nausea does not improve, becomes worse, repeatedly causes vomiting, makes it difficult to eat or drink, or disrupts your daily activities. Other health conditions and medicines can also cause nausea, so a clinician may review the timing of symptoms, your medical history, and your current medications before deciding what to do next.
Seek emergency medical care if nausea or vomiting occurs alongside symptoms such as confusion, marked agitation, fever, heavy sweating, shaking, muscle twitching, a rapid heartbeat, or loss of coordination, particularly after starting or increasing a serotonin-affecting medicine or combining medicines that affect serotonin. MedlinePlus describes these as possible features of serotonin syndrome, a potentially life-threatening reaction to certain medicines. Nausea alone does not establish that this reaction is occurring, but the combination of symptoms requires urgent assessment.
