Ayahuasca Dosage Guide

## Can You Fatally Overdose on Ayahuasca? Fatal overdose from properly prepared traditional ayahuasca brew alone is extraordinarily unlikely. The volume of liquid required to approach a lethal dose would be physically impossible to consume and retain. The estimated lethal dose is roughly 50 times a standard ceremonial serving. However, deaths in ayahuasca contexts are documented -- and they are almost always caused by drug interactions, admixture with dangerous plants, or pre-existing medical conditions rather than by DMT or harmala alkaloid toxicity itself. ## Recognizing Serotonin Syndrome This is the most dangerous acute risk and requires immediate medical intervention: - **Early signs**: agitation, restlessness, dilated pupils, diarrhea (beyond normal purging), rapid heartbeat, elevated blood pressure - **Moderate**: muscle twitching (clonus), hyperreflexia, profuse sweating, fever above 38°C / 100.4°F - **Severe / life-threatening**: temperature above 41°C / 106°F, muscle rigidity (especially in the legs), seizures, irregular heartbeat, loss of consciousness Serotonin syndrome can develop within hours of ingestion, particularly if serotonergic medications were not adequately tapered. It progresses rapidly and can be fatal without treatment. ## Recognizing Hypertensive Crisis If ayahuasca is taken with tyramine-rich foods or certain medications: - Sudden, severe headache (often described as the worst headache of their life) - Chest pain or tightness - Rapid or pounding heartbeat - Nausea and vomiting (distinct from normal purging in its severity and timing) - Visual disturbances, confusion - Neck stiffness ## Recognizing Psychological Crisis vs. Normal Ceremony Not everything that looks alarming during ceremony requires medical intervention. Intense crying, shaking, screaming, and writhing are within the range of normal ceremonial experience. What warrants concern: - **Prolonged unresponsiveness** beyond what is expected for the dose and timing - **Self-harm attempts** or attempts to flee into unsafe environments - **Persistent psychotic symptoms** (paranoid delusions, command hallucinations) that continue well past the peak - **Suicidal ideation** expressed clearly ## Emergency Response - **Serotonin syndrome**: Call emergency services immediately. In a medical setting, cyproheptadine (a serotonin antagonist) is the first-line treatment. Cooling measures for hyperthermia. IV fluids. Benzodiazepines for seizures and agitation - **Hypertensive crisis**: Emergency services. Phentolamine or nifedipine in a medical setting - **Aspiration risk**: If someone is vomiting while supine or semi-conscious, place them in the recovery position immediately. Do not leave them on their back - **Severe dehydration**: Persistent vomiting and diarrhea with inability to retain fluids requires IV rehydration - **Psychological crisis**: Calm, grounding presence. Reassurance that the experience is temporary. Do not try to "talk them out of it" during peak -- just ensure physical safety. Benzodiazepines (diazepam 10-20 mg) can reduce psychological intensity if needed Good Samaritan laws protect people who call for help during drug emergencies. Be completely honest with medical personnel about what was consumed -- including the MAOI component, which is critical for treatment decisions.
