TrkB/BDNF'"`UNIQ--ref-00000084-QINU`"' '"`UNIQ--vote-00000085-QINU`"' (1) ·
Weak SRI; primarily H1/D2/alpha antagonist (1)
uses:
None (47) ·
Depression, anxiety, neuropathic pain, fibromyalgia, chronic musculoskeletal pain (1) ·

starting dose:
None (47) ·
0.4 mg PO daily (general prevention); 0.8-1 mg/d in pregnancy; 4 mg/d for women with prior NTD-affected pregnancy; 1 mg/d during methotrexate therapy (1) ·
25 mg (1) ·
325 mg PO daily to TID (=65 mg elemental iron/tablet); alternate-day dosing is now favored by hepcidin physiology for better absorption with less GI burden (1) ·
No medical dose. Active recreational doses reported in the 0.5–1.5 mg range (similar potency to alprazolam). (1) ·
Replacement: 1000 mcg IM daily for 1 week, then weekly for 4 weeks, then monthly; or 1000-2000 mcg PO daily (effective even in pernicious anemia via passive diffusion); intranasal 500 mcg weekly (1)
preparations:
None (47) ·
0.4, 0.8, 1 mg OTC; 1 mg Rx; 5 mg/mL injection (1) ·
100, 250, 500, 1000, 5000 mcg tablets (OTC and Rx); 1000 mcg/mL injection; intranasal spray; sublingual (1) ·

325 mg tablets (65 mg elemental Fe); 220 mg/5 mL liquid (44 mg elemental Fe/5 mL); 142 mg/mL drops; OTC and Rx (1) ·
Illicit tablets ("bars"), powders, blotter, occasionally solutions. No pharmaceutical product exists. (1)
fda max:
routes:
onset:
None (46) ·
Anxiolysis classically 3-4 weeks, continuing improvement to 8-12 weeks (1) ·
Hematologic response within days (1) ·
Mood: 2–4 weeks. Pain: often within 1–2 weeks. (1) ·
Reticulocyte response at 3-5 days; neurologic recovery weeks to months (and may be incomplete if longstanding) (1) ·
Reticulocyte response at 7-10 days; hemoglobin rise of ~1 g/dL per 3 weeks (1) ·
~20–40 min PO; faster sublingual/intranasal. (1)
duration:
halflife:
None (46) ·
Estimated ~12–17 h (some sources cite up to ~21 h); active metabolites prolong effect. (1) ·
N/A (incorporated into hemoglobin and tissue stores) (1) ·
~0.5 hours plasma; tissue retention longer (1) ·
~12 hours (1) ·
~26 h (sertraline; range 13-45 h, longer in females); ~62-104 h (N-desmethylsertraline, weakly active) (1) ·
~6 days (plasma); hepatic stores last 3-5 years (1)
bioavailability:
None (46) ·
10-20% (oral; reduced by food, calcium, antacids, PPIs, tea/coffee; enhanced by ascorbate) (1) ·
Absolute bioavailability not precisely characterized; food modestly increases exposure (1) ·
High (oral) (1) ·
Not formally characterized in humans. (1) ·
Oral ~1-3% via passive diffusion at high doses (independent of intrinsic factor); IM/SC ~100% (1) ·
~50% (highly variable) (1)
pregnancy:
None (46) ·
Avoid. Benzodiazepines are associated with neonatal sedation, floppy-infant syndrome, and withdrawal; teratogenic signal weak but non-zero. Designer benzo with no safety data, assume worst-case. (1) ·
