I now have comprehensive information from multiple authoritative sources. Let me compile this into a clear management algorithm with drugs from first-line to last.

Management of Postpartum Psychosis (PPP): Treatment Algorithm

Background

PPP is a medical emergency affecting 0.1-0.2% of postpartum women (1-2 per 1,000 births). It typically presents within the first 2 weeks after delivery and is an affective psychosis - not merely an exacerbation of a pre-existing primary psychotic illness. It carries a 70-fold increased suicide risk in the first 12 months postpartum, and significant infanticide risk. If treated aggressively early, prognosis is good.

STEP 0: IMMEDIATE ACTIONS (Before Pharmacotherapy)

RECOGNIZE → REFER → ADMIT
│
├── Mandatory psychiatric hospitalization
├── Never leave patient alone with infant
├── Rule out organic causes:
│     - Eclampsia
│     - Pituitary infarction (Sheehan's)
│     - Cerebral venous thrombosis
│     - Hypoxic-hypotensive brain injury
│     - Ergot-induced psychosis
│     - Thyroid dysfunction
├── Collateral history (consciousness waxes/wanes like delirium)
└── Assess breastfeeding plan → determines drug selection

ALGORITHM: Drug Treatment (First → Last Line)

TIER 1 - FIRST-LINE TREATMENT

┌─────────────────────────────────────────────────────────────────┐
│         FIRST-LINE: LITHIUM + ATYPICAL ANTIPSYCHOTIC            │
├─────────────────────────────────────────────────────────────────┤
│                                                                 │
│  LITHIUM (gold standard)                                        │
│  • 98% response rate in longitudinal studies                    │
│  • Prophylaxis started at delivery or within 24h postbirth      │
│  • Nearly 10-fold decrease in recurrence rate                   │
│  • Sustained remission to 9 months postpartum                   │
│  • ⚠ CONTRAINDICATED in breastfeeding (advise formula)          │
│  • Monitor serum levels, renal function, thyroid                │
│                                                                 │
│  ATYPICAL ANTIPSYCHOTIC (added for acute symptom control)       │
│  • Olanzapine (preferred if breastfeeding planned)              │
│  • Quetiapine (preferred if breastfeeding planned)              │
│  • Risperidone (caution: highest malformation signal among SGAs)│
│  • Haloperidol (FGA option; low-dose, mid-potency)              │
│  • Perphenazine (PRN for prodromal/breakthrough symptoms)       │
│  ⚠ Antipsychotics manage symptoms but do NOT replace lithium    │
└─────────────────────────────────────────────────────────────────┘

Breastfeeding note: If patient is breastfeeding - continue lithium but stop breastfeeding. If breastfeeding must continue, use olanzapine or quetiapine as mood-stabilizing antipsychotics instead.

TIER 2 - ADJUNCTIVE AGENTS (Added to Tier 1 as needed)

┌─────────────────────────────────────────────────────────────────┐
│  BENZODIAZEPINES (adjunct for agitation, insomnia, anxiety)    │
├─────────────────────────────────────────────────────────────────┤
│  • Lorazepam - preferred (shorter half-life)                    │
│  • Clonazepam                                                   │
│  • Use short-term; caution in breastfeeding (infant sedation    │
│    and withdrawal risk)                                         │
│  • Especially useful in catatonic features (with ECT)          │
└─────────────────────────────────────────────────────────────────┘

TIER 3 - SECOND-LINE: ALTERNATIVE MOOD STABILIZERS

┌─────────────────────────────────────────────────────────────────┐
│  If lithium not tolerated or contraindicated:                   │
├─────────────────────────────────────────────────────────────────┤
│  • Olanzapine / Quetiapine as mood-stabilizing antipsychotics   │
│    (can replace lithium as mood stabilizer postpartum)          │
│                                                                 │
│  ⚠ Valproate - AVOID if possible (teratogen, and generally      │
│    avoided in women of childbearing age; not supported by RCT   │
│    for postpartum prophylaxis)                                  │
│  ⚠ Carbamazepine - AVOID (major teratogen; poor evidence        │
│    for postpartum prophylaxis)                                  │
└─────────────────────────────────────────────────────────────────┘

TIER 4 - THIRD-LINE / REFRACTORY

┌─────────────────────────────────────────────────────────────────┐
│  CLOZAPINE                                                      │
├─────────────────────────────────────────────────────────────────┤
│  • For treatment-resistant psychosis                            │
│  • ⚠ CONTRAINDICATED in breastfeeding (advise to stop)         │
│  • Highest metabolic risk (gestational diabetes, weight gain)   │
│  • Requires mandatory blood monitoring                          │
└─────────────────────────────────────────────────────────────────┘

TIER 5 - LAST RESORT / SPECIAL CIRCUMSTANCES

┌─────────────────────────────────────────────────────────────────┐
│  ELECTROCONVULSIVE THERAPY (ECT)                                │
├─────────────────────────────────────────────────────────────────┤
│  • Reserved for refractory cases                                │
│  • Indicated when:                                              │
│    - No response to pharmacotherapy                             │
│    - Severe catatonia (with or without lorazepam)               │
│    - Imminent danger (suicidality/infanticide) requiring rapid  │
│      response                                                   │
│    - Severe depression with psychosis not responding to drugs   │
│    - Need to avoid medications (e.g., medical contraindications)│
│  • Evidence: 2026 systematic review confirms effectiveness      │
│    (PMID: 42201669)                                             │
│  • Also consider rTMS in patients avoiding medications          │
└─────────────────────────────────────────────────────────────────┘

MAINTENANCE & PROPHYLAXIS

Phase	Recommendation
Acute (weeks 1-4)	Lithium + antipsychotic + BZD as needed
Continuation (months 1-9)	Lithium maintenance; sustained remission to 9 months
Prophylaxis (future pregnancies)	Lithium started in late pregnancy or within 24h of birth
Mood stabilizer discontinuation	85% relapse rate if discontinued - avoid stopping

BREASTFEEDING QUICK REFERENCE

Drug	Breastfeeding
Lithium	Contraindicated - stop breastfeeding
Clozapine	Contraindicated - stop breastfeeding
Olanzapine	Acceptable (preferred postpartum antipsychotic)
Quetiapine	Acceptable (preferred postpartum antipsychotic)
Haloperidol	Acceptable with monitoring
Lorazepam	Caution (short-term, watch for sedation/withdrawal)
Valproate	Use with caution; avoid if possible

KEY POINTS

Lithium is the gold standard with ~98% response rate - Kaplan & Sadock's Comprehensive Textbook of Psychiatry
Antipsychotics are first-line for acute symptom control but do not replace lithium - Swanson's Family Medicine Review
ECT is reserved for refractory cases or severe catatonia - not a first-line option
Valproate and carbamazepine should be avoided postpartum in women of childbearing age
PPP is closely linked to bipolar disorder (50-80% of PPP cases eventually diagnosed as bipolar) - treat as affective psychosis
Discontinuing mood stabilizers is the strongest trigger for relapse (85% relapse rate) - never stop abruptly
