3-MeO-PCE Dosage Guide

## Recognizing an Overdose The primary overdose risk with 3-MeO-PCE is psychiatric, not respiratory — though both are possible. Signs that require immediate attention include: - **Manic or psychotic behavior** — Grandiose delusions, paranoia, agitation, aggressive or bizarre behavior, loss of contact with reality. This is the most common form of 3-MeO-PCE overdose and can emerge even at doses only modestly above the intended range - **Complete unresponsiveness** — Inability to be roused by voice or physical stimulation beyond the expected duration (more than 6-8 hours) - **Seizures** — Rare but documented with arylcyclohexylamine overdoses - **Severely elevated heart rate or blood pressure** — The stimulant properties mean cardiovascular crisis is a real concern at high doses - **Respiratory depression** — Particularly in combination with CNS depressants - **Vomiting while unconscious** — Aspiration risk when protective reflexes are suppressed ## What To Do For psychiatric emergencies (mania, psychosis, agitation): move the person to a calm, low-stimulation environment. Speak calmly and avoid confrontation. Administer a benzodiazepine (diazepam 10-20 mg) if available and the person can swallow safely. Call emergency services if the person is a danger to themselves or others, if psychotic symptoms are severe, or if the situation is not improving. For physical emergencies: place the person in the recovery position to prevent aspiration. Monitor breathing continuously. Call emergency services immediately if breathing is slow, shallow, or irregular, if the person is unresponsive to stimulation, or if seizures occur. Be honest with medical personnel about what was consumed and approximate timing and dose — 3-MeO-PCE is obscure enough that clinicians are unlikely to be familiar with it, so providing the name and noting that it is a potent NMDA antagonist with stimulant properties is genuinely helpful for treatment decisions. ## Why 3-MeO-PCE Overdoses Happen The combination of compulsive redosing urges, delusions of sobriety, and extremely long duration creates a characteristic overdose pattern. Users redose during what they perceive as the come-down, not realizing they are still significantly intoxicated. Each additional dose extends the experience and increases the probability of psychiatric adverse effects. The stimulant component maintains a false sense of lucidity that delays recognition of how impaired the person actually is.
