[ Frequently Asked Questions ](#blog-faqs) 11. [ References ](#references-heading) A patient starts sertraline on Monday, messages on Friday that she is sleeping 3 hours a night, feels “amazing,” and has bought plane tickets she cannot afford. Another stops venlafaxine over a weekend and shows up with dizziness, nausea, and “brain zaps.” These are classic primary care moments: the prescription was easy; the monitoring was the real job. [\[1\]](#cite-1 "Reference [1]") Start with the diagnosis, not the drug -------------------------------------- Before you write for an SSRI or SNRI, rule out bipolar spectrum illness as best you can in primary care. ACOG explicitly recommends bipolar screening before starting pharmacotherapy for depression or anxiety in perinatal patients because antidepressant monotherapy can worsen mood symptoms and precipitate mania or psychosis; the VA/DoD bipolar guideline likewise flags irritability, agitation, high energy on little sleep, and mania after antidepressant initiation as red flags for bipolar disorder. [\[2\]](#cite-2 "Reference [2]") Ask three things every time: - Any past period of **decreased need for sleep**, unusually high energy, racing thoughts, impulsive spending, or feeling unusually powerful or irritable? [\[3\]](#cite-3 "Reference [3]") - Any first-degree family history of bipolar disorder or suicide? [\[4\]](#cite-4 "Reference [4]") - Any prior antidepressant that caused marked activation, agitation, or a “too good, too fast” response? [\[5\]](#cite-5 "Reference [5]") Board pitfall: don’t confuse **activation** with recovery. Early jitteriness, insomnia, or anxiety can happen after initiation or dose increase, but decreased need for sleep, risky behavior, grandiosity, or rapidly escalating goal-directed activity should make you think hypomania or mania until proven otherwise. [\[5\]](#cite-5 "Reference [5]") > **Clinical Pearl:** If a “depressed” patient feels dramatically better in a few days and stops needing sleep, stop congratulating yourself and reassess for bipolar disorder. [\[4\]](#cite-4 "Reference [4]") Follow-up timing: front-load the monitoring ------------------------------------------- The first follow-up should not be an afterthought. NICE recommends review within **2 weeks** after starting an antidepressant to assess symptom change and side effects, and within **1 week** for people aged 18 to 25 years or when suicide risk is a concern; FDA labeling also calls for close observation during the initial months and after dose changes for worsening, suicidality, and unusual behavioral changes. [\[6\]](#cite-6 "Reference [6]") At each early follow-up, check: - suicidal ideation and emerging agitation - adherence and whether the patient actually started the medication - sleep, appetite, energy, and GI tolerability - activation or manic symptoms - objective symptom change with a validated scale such as PHQ-9 when possible. [\[6\]](#cite-6 "Reference [6]") If the drug is going to help, some benefit is usually expected within about **4 weeks**. Don’t declare failure at day 7 unless the problem is intolerance, suicidality, or emerging mania. [\[6\]](#cite-6 "Reference [6]") Side effects that actually change management -------------------------------------------- The common SSRI/SNRI adverse effects are familiar, but monitoring matters because a few of them alter prescribing strategy. IssueTypical clueMonitoring moveEarly common effectsNausea, diarrhea, headache, insomnia, sexual dysfunctionWarn before prescribing; SNRIs cause more nausea/vomiting than SSRIs. [\[7\]](#cite-7 "Reference [7]")Drug-specific concernsVenlafaxine/duloxetine can raise BP; citalopram can prolong QTCheck BP before and during SNRIs; be cautious with QT-risk combinations. [\[8\]](#cite-8 "Reference [8]")Higher-risk patientsOlder adults, diuretic users, NSAID/antiplatelet usersThink hyponatremia and GI bleed risk; sodium monitoring 2 to 4 weeks after starting is reasonable in older adults. [\[7\]](#cite-7 "Reference [7]") In family medicine, the best monitoring questions are simple: “Are you sleeping?”, “Any nausea or sexual side effects?”, “Any restlessness that feels unlike you?”, and for SNRIs, “What is the blood pressure doing?” [\[7\]](#cite-7 "Reference [7]") Serotonin syndrome: rare, but board-relevant -------------------------------------------- Serotonin syndrome is usually a **combination-drug** problem, not a routine SSRI dose problem. Most patients present within **6 to 24 hours** of a medication change or overdose, and the exam clue boards love is **clonus with hyperreflexia**, often with agitation, diaphoresis, diarrhea, or fever. [\[9\]](#cite-9 "Reference [9]") Use the Hunter framework in your head: spontaneous clonus; inducible or ocular clonus with agitation or diaphoresis; tremor plus hyperreflexia; or hypertonia with fever and clonus. Stop the offending serotonergic drugs, provide supportive care, and escalate to the ED or hospital for moderate or severe toxicity. [\[9\]](#cite-9 "Reference [9]") Discontinuation syndrome: prevent it, don’t chase it ---------------------------------------------------- Discontinuation syndrome typically follows abrupt cessation or large dose reduction after at least a month of treatment. Symptoms often begin within days and include the **FINISH** cluster: flulike symptoms, insomnia, nausea, imbalance, sensory disturbances, and hyperarousal; patients may also report dizziness and electric-shock sensations. [\[7\]](#cite-7 "Reference [7]") High-yield exam fact: **paroxetine and venlafaxine** are more likely to cause withdrawal symptoms; **fluoxetine** is less likely because of its long half-life. Taper gradually over weeks, and sometimes months, with pace guided by symptoms rather than your refill schedule. [\[10\]](#cite-10 "Reference [10]") Pregnancy and postpartum: don’t panic-prescribe or panic-stop ------------------------------------------------------------- For perinatal depression, ACOG recommends SSRIs as first-line pharmacotherapy and SNRIs as reasonable alternatives. If there is no prior medication history, **sertraline or escitalopram** are reasonable first-line choices; if a patient previously responded well to another antidepressant, that prior response should strongly influence selection. [\[1\]](#cite-1 "Reference [1]") Just as important, ACOG recommends **against withholding or discontinuing** psychiatric medication because of pregnancy or lactation status alone. Fluoxetine’s long half-life may increase neonatal adaptation symptoms and accumulation in breastfed infants, but prior effectiveness still matters; meanwhile, any suspected bipolar disorder should push you away from antidepressant monotherapy and toward specialist collaboration. [\[1\]](#cite-1 "Reference [1]") Clinical Correlations in Family Medicine ---------------------------------------- This is why antidepressant prescribing belongs in longitudinal care. You are the clinician who sees the insomnia before it becomes mania, the nausea before nonadherence, the elevated BP after an SNRI titration, and the “relapse” that is really withdrawal. Good primary care prescribing is not choosing a pill; it is building a monitoring plan the patient can actually follow. [\[6\]](#cite-6 "Reference [6]") Key Takeaways ------------- - Screen for bipolar features before starting SSRIs or SNRIs, especially in pregnancy and postpartum care. [\[2\]](#cite-2 "Reference [2]") - Review most patients within **2 weeks**; see higher-risk patients within **1 week**. [\[6\]](#cite-6 "Reference [6]") - Watch for activation, but treat decreased need for sleep and risky behavior as possible mania. [\[5\]](#cite-5 "Reference [5]") - Expect common GI and sexual adverse effects; monitor BP with SNRIs. [\[7\]](#cite-7 "Reference [7]") - Think serotonin syndrome when clonus and hyperreflexia follow a serotonergic change. [\[9\]](#cite-9 "Reference [9]") - Taper slowly; paroxetine and venlafaxine are classic discontinuation offenders. [\[10\]](#cite-10 "Reference [10]") - In pregnancy, don’t stop an effective antidepressant reflexively; individualize the risk-benefit discussion. [\[1\]](#cite-1 "Reference [1]") Conclusion ---------- Antidepressants are safe primary care tools only when paired with deliberate monitoring. Screen for bipolar disorder, follow early, teach side effects before they happen, and never miss the two things boards and real life both punish: mania and serotonin toxicity. [\[2\]](#cite-2 "Reference [2]") Frequently Asked Questions ---------------------------- ### How do I distinguish antidepressant activation from emerging mania? Activation usually looks like anxiety, restlessness, or insomnia soon after starting or increasing the dose. Mania is more concerning when you see decreased need for sleep, risky behavior, racing thoughts, grandiosity, or clear functional escalation. [\[5\]](#cite-5 "Reference [5]") ### When should I bring a patient back after starting an SSRI or SNRI? A practical evidence-based approach is follow-up within 2 weeks, or within 1 week for patients aged 18 to 25 years or anyone with suicide risk. Early review should check side effects, adherence, suicidality, and activation. [\[6\]](#cite-6 "Reference [6]") ### Which antidepressants are reasonable first choices in pregnancy? For perinatal depression, SSRIs are first-line and SNRIs are reasonable alternatives. If there is no prior medication history, ACOG considers sertraline or escitalopram reasonable first-line options. [\[1\]](#cite-1 "Reference [1]") ### What antidepressants most often cause discontinuation syndrome? Paroxetine and venlafaxine are classic high-risk agents because withdrawal is more common with shorter half-life drugs. Fluoxetine is lower risk because of its long half-life.
