Antidepressant Side Effects: What to Expect and How to Manage
Starting an antidepressant is a big step. You may feel better — but side effects can pop up, especially in the first few weeks. Knowing what’s common, what’s temporary, and when to get help makes the whole process less stressful.
Most antidepressants share a handful of common effects: nausea, headache, dizziness, sleep changes, dry mouth, sweating, and sexual problems. People on SSRIs (like sertraline or fluoxetine) often report nausea and sexual side effects. SNRIs (venlafaxine, duloxetine) can cause high blood pressure or increased sweating. Tricyclics may make you sleepy and cause dry mouth or constipation. Each drug has its own pattern, but many side effects ease after 1–4 weeks as your body adjusts.
When side effects start and how long they last
Side effects usually begin within days to the first two weeks. Some—like nausea or headache—fade after a week or two. Sexual side effects and weight changes may take longer to show up and can persist. Stopping an antidepressant suddenly can cause discontinuation symptoms (dizziness, electric shock sensations, flu-like symptoms). That’s why any change should be guided by your prescriber.
Practical ways to reduce common side effects
Try simple fixes before switching drugs. If you feel nauseous, take your pill with food or at bedtime. For insomnia, switch to morning dosing or talk to your clinician about changing the timing. If you’re tired, try taking it at night. Dry mouth improves with frequent sips of water, sugar-free gum, or saliva substitutes. Constipation often helps with more fiber, water, and activity.
Sexual side effects can be frustrating. Options include waiting to see if it improves, lowering the dose under medical supervision, adding a medication like bupropion, or switching to a different antidepressant. Talk openly with your provider — sexual side effects are common and solvable in many cases.
Watch for safety red flags: new or worsening suicidal thoughts, severe agitation, chest pain, very high fever, or signs of serotonin syndrome (rapid heartbeat, high temperature, confusion, tremors). If you notice these, get urgent medical help. Young people under 25 may have a higher risk of mood changes when starting treatment, so close follow-up is key.
Keep a short symptom log for the first month: note the side effect, when it started, how severe it is, and what you tried to relieve it. Bring this to appointments — it helps your clinician make a smarter choice. Also mention other drugs, supplements, and alcohol, since interactions can make side effects worse.
Antidepressants work, but finding the right one often requires adjustments. Be honest with your doctor, ask about timelines, and don’t stop medication on your own. With a little tracking and good communication, most side effects can be managed or avoided altogether.
