Anxiety medication in India requires a prescription. SSRIs (sertraline, escitalopram), SNRIs (venlafaxine), and beta-blockers (propranolol) all have different mechanisms and safety profiles. Before medicating, test thyroid (TSH/FT3/FT4), cortisol, B12, vitamin D, and iron — 30%+ of anxiety has a metabolic root cause. Benzodiazepines should never be first-line; they're addictive and meant for crisis only.
Over 200 million Indians have anxiety. Less than 10% are treated. Most of those who are treated start with the same drug: benzodiazepines (Alprazolam, Clonazepam). Doctors prescribe them because they work fast — anxiety relief within 30 minutes. But they're addictive, meant for crises only, never for months. Yet in India, anxious patients walk away with prescriptions for years. This is not safe. There are non-addictive alternatives that work, just not as fast. They take 2-4 weeks to kick in. But they don't create dependence, don't impair driving or work, and can be taken long-term without losing effectiveness. This guide covers those alternatives, why bloodwork matters before prescribing, and how arq. approaches anxiety treatment differently.
Anxiety is the most common mental health condition in India. Generalized anxiety disorder (GAD), panic disorder, social anxiety, performance anxiety — the prevalence estimates range from 8-15% of the population. That's roughly 200 million people. Yet fewer than 1 in 10 receive any treatment. Why?
Because mental health is still stigmatized. Because psychiatrist access is limited to metros. Because most primary care doctors either dismiss anxiety ("it's stress, just relax") or over-prescribe benzodiazepines ("take this for calm").
Benzodiazepines do work. They're GABA agonists — they increase inhibitory neurotransmission, dampening anxiety within 30 minutes. But they're hazardous as monotherapy Benzodiazepines create dependence within 2-4 weeks of daily use. The brain adapts to heightened GABA, so you need higher doses for the same effect (tolerance). Stop suddenly, and you get rebound anxiety, insomnia, tremors, panic. The patient feels trapped: the drug helped, but now they're addicted.
In clinical guidelines worldwide (DSM-5, APA, NICE), benzodiazepines are recommended only for acute crisis management — not exceeding 2-4 weeks. India's practice lags. Many patients are on chronic benzodiazepine monotherapy, which is substandard.
The standard of care is first-line: SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors). They take longer (2-4 weeks), but they don't create dependence, don't impair cognition, and work long-term. If acute severe anxiety needs rapid relief, a benzodiazepine is added temporarily, then tapered as the SSRI kicks in.
Escitalopram (Nexito) and Sertraline (Zoloft) are the most commonly prescribed SSRIs for anxiety in India. Both are first-line in international guidelines for generalized anxiety disorder, panic disorder, and social anxiety.
Mechanism: SSRIs block the reuptake of serotonin at the synapse, increasing serotonin availability in the brain. Serotonin regulates mood, anxiety, and stress response. More serotonin, better regulation. Timeline: 2-4 weeks for initial improvement, 6-8 weeks for full effect.
Escitalopram dosing: Start 5-10 mg daily, titrate to 10-20 mg. Cost: ~200 INR/month.
Sertraline dosing: Start 50 mg daily, titrate to 100 mg. Cost: ~150 INR/month.
Side effects: Nausea, headache, restlessness in first 1-2 weeks (usually resolve). Sexual side effects (reduced libido, delayed ejaculation) in 10-20% — persistent for some. Switching to SNRIs or dose reduction helps. Serious side effects are rare but include serotonin syndrome (drug interaction with other serotonergic agents) and hyponatremia (low sodium, especially in elderly).
Venlafaxine (Effexor) and Duloxetine (Cymbalta) work on both serotonin and norepinephrine. They're equally effective for anxiety and often preferred if SSRIs cause sexual dysfunction.
Venlafaxine dosing: Start 37.5 mg daily, titrate to 75-150 mg. Cost: ~300 INR/month.
Duloxetine dosing: Start 30 mg daily, titrate to 60 mg. Cost: ~250 INR/month.
Advantage: SNRIs may have less sexual dysfunction than SSRIs Disadvantage: Slightly higher discontinuation syndrome if you stop abruptly (dizziness, "brain zaps"), so tapering must be careful.
Buspirone is a serotonin 1A agonist — it directly stimulates serotonin receptors, calming anxiety without sedation or dependence. It's non-controlled, no addiction risk, and doesn't impair cognition or driving.
Dosing: 5-10 mg twice daily, titrate to 15-20 mg. Cost: ~100 INR/month.
Advantage: Safe, non-addictive, well-tolerated Disadvantage: Slower onset (4-6 weeks), less effective for panic disorder. Often used as an add-on to SSRIs, not monotherapy.
Hydroxyzine is an antihistamine with anxiolytic properties. Unlike benzodiazepines, it's not controlled and has no addiction potential.
Dosing: 25-50 mg as needed, up to three times daily. Cost: ~50 INR/month.
Use: Short-term bridge for acute anxiety while waiting for SSRIs to work (2-4 weeks), or for situational anxiety (presentations, exams, travel). Side effect: Sedation, so not ideal for daytime anxiety unless drowsiness is acceptable.
Propranolol is a beta-blocker. It reduces the physical symptoms of anxiety — racing heart, trembling, sweating — without addressing the psychological component. Effective for performance anxiety, public speaking, exams.
Dosing: 10-20 mg one hour before the triggering event. Cost: ~50 INR/month.
Use: Not for chronic anxiety, but for specific predictable situations where physical symptoms dominate.

| Test | How It Mimics Anxiety | Normal Range | Treatment |
|---|---|---|---|
| TSH + Free T4 (Thyroid) |
Hyperthyroidism → racing heart, tremor, panic. Hypothyroidism → anxiety + depression | TSH: 0.4-4.0 mIU/L | Levothyroxine or antithyroids; recheck in 6-8 weeks |
| Serum Iron + Ferritin (Iron stores) |
Iron deficiency → restlessness, insomnia, anxiety, poor concentration | Ferritin: 30-300 ng/mL | Iron supplementation (ferrous sulfate 325 mg daily); recheck in 8-12 weeks |
| Vitamin B12 + Folate | Deficiency → neuropsychiatric symptoms, anxiety, depression, neuropathy | B12: >200 pg/mL Folate: >5.4 ng/mL |
B12 supplementation (1000 mcg IM monthly) or oral; folate 800-1000 mcg daily |
| Fasting Cortisol (Morning) |
Elevated cortisol → chronic anxiety, sleep disruption, hypervigilance | 5-25 mcg/dL (morning) | Stress reduction, sleep optimization, consider adaptogens; rule out Cushing's if >30 |
| Fasting Blood Sugar + HbA1c | Hypoglycemia → acute anxiety, tremor, palpitations. Insulin resistance → metabolic stress | FBS: 70-100 mg/dL HbA1c: <5.7% |
Dietary carbs/protein balance, chromium supplementation; screen for prediabetes |
| Vitamin D (25-OH) | Deficiency (endemic in India) → anxiety, depression, seasonal affective symptoms | >30 ng/mL (optimal >40) | Vitamin D3 supplementation 2000-4000 IU daily; recheck in 3 months |
Anxiety is a symptom, not always a diagnosis. Many medical conditions mimic anxiety: thyroid disease, iron deficiency, hypoglycemia, high cortisol, anemia, Vitamin D deficiency. If you treat the symptom without finding the cause, you're missing the diagnosis.
Hyperthyroidism causes anxiety, palpitations, tremor, and irritability — identical to anxiety disorder. Hypothyroidism causes depression and anxiety. Yet many anxious patients in India are never screened for thyroid. This is inexcusable. TSH is cheap (~200 INR) and essential. Treat the thyroid first; if anxiety persists after thyroid is normalized, then prescribe an SSRI.
Iron deficiency causes anxiety and restlessness. B12 and folate deficiency cause neuropsychiatric symptoms. Common in vegetarians and vegans. Supplement if deficient; anxiety often improves without psychiatric medication.
Elevated morning cortisol suggests chronic stress or adrenal dysfunction — contributes to anxiety. Hypoglycemia (low blood sugar) causes acute anxiety. Check fasting glucose, HbA1c, and morning cortisol if symptoms suggest metabolic causes.
Anemia reduces oxygen delivery to the brain, causing anxiety and fatigue. CBC identifies it in minutes.
Vitamin D deficiency is endemic in India (even in sunny regions, due to cultural practices). Deficiency is associated with anxiety and depression. Level should be >30 ng/mL; supplement if low.
SSRIs stabilize your brain chemistry. But they don't teach you how to think differently about anxiety. Cognitive Behavioral Therapy (CBT) does. CBT teaches you to identify anxiety triggers, challenge catastrophic thoughts ("this presentation will go badly" → "I've done presentations before"), and develop coping strategies (breathing, grounding, exposure).
The combination is superior: medication handles neurochemistry; therapy handles cognition and behavior. Ideally, do both. In India, CBT access is improving through online platforms and urban therapists, but it's still limited. arq. can prescribe medication effectively; for therapy, we can connect you to resources.
Anxious and unsure where to start? Get tested for medical causes, then get the right medication. Talk to an arq. physician →
Weeks 1-2: Nausea, headache, restlessness possible (usually mild and transient). Anxiety hasn't improved yet — be patient. Continue the medication.
Weeks 2-4: Nausea resolves. You may notice slight mood improvement. Sleep might improve first. Anxiety still present but slightly better.
Weeks 4-8: Significant improvement in anxiety, racing thoughts, restlessness. You feel calmer. This is the target effect.
Weeks 8+: Full benefit. If you're not at full dose yet, your physician may increase it. Ongoing monitoring ensures it's working and you're not experiencing side effects.
SSRIs are safe long-term. You can take them for years. No increased cancer risk, dementia risk, or organ damage. However, long-term use requires monitoring: bloodwork annually to check liver/kidney function, blood glucose, and sodium levels. And periodically (every 1-2 years), reassess whether you still need it — some people can taper off successfully; others need to stay on.
Abrupt cessation after >4 weeks causes discontinuation syndrome: anxiety, insomnia, headache, dizziness, "brain zaps" (electrical sensations). Never stop cold turkey. Taper over 2-4 weeks under your physician's guidance. Longer use (>3 months) requires slower tapering. Your physician will guide you.
