Who this guide is for:
First-time retreat seekers, returning guests, or anyone wondering, “Is ayahuasca actually safe for me?”
You’ve read the glowing testimonials. The promises of deep healing. But what most ayahuasca websites and wellness influencers don’t tell you is this:
Ayahuasca can be medically dangerous – even fatal – if the right precautions aren’t taken.
This guide outlines the known health risks of ayahuasca in 2025, including drug interactions, cardiovascular stress, psychiatric contraindications, and real-life emergencies. It also gives you a checklist of what to ask a retreat before booking – so you can stay informed, not blindsided.
🚨 Quick Answer: Who Should Not Drink Ayahuasca?
Avoid ayahuasca (or get full medical clearance first) if you:
- Take SSRIs, MAOIs, or other psychiatric meds
- Have a history of bipolar disorder, psychosis, or schizophrenia
- Struggle with high blood pressure or heart conditions
- Are actively using stimulants, opioids, or benzodiazepines
- Cannot access professional guidance for tapering medications safely
🧬 Drug Interactions: The Most Documented Danger
The #1 cause of medical emergencies during ayahuasca retreats? Combining the brew with prescription drugs.
High-Risk Meds Include:
- SSRIs & SNRIs (e.g., Prozac, Zoloft, Lexapro): can cause serotonin syndrome
- MAOIs or RIMAs: amplify MAO-inhibiting effects dangerously
- Benzodiazepines (e.g., Xanax, Klonopin): can dull the experience or cause seizures when withdrawn too quickly
- ADHD Meds (e.g., Adderall): increase heart strain, psychological instability
- Opioids, Tramadol, Triptans: risk of serotonin overload or respiratory failure
🧠 Important: You can’t just stop these meds “a few days before.” Many remain in your system for weeks. Discontinuation should always be done with licensed medical supervision.
❤️ Heart and Blood Pressure Dangers
Ayahuasca temporarily increases:
- Blood pressure
- Heart rate
- Vascular stress
This makes it unsafe for people with:
- Hypertension (even if “managed”)
- Irregular heartbeat or arrhythmia
- History of fainting or cardiovascular disease
Altitude makes this worse. Many Amazon retreats sit at 5,000+ feet above sea level, compounding heart strain.
🧠 Psychiatric Contraindications
Ayahuasca can unearth deep emotional trauma. That can be therapeutic – but also destabilizing.
Not recommended for individuals with:
- Schizophrenia or schizoaffective disorder (including family history)
- Bipolar disorder
- PTSD with unresolved dissociation
- Severe anxiety or panic attacks
Even depression may worsen short-term. Without proper support, a breakthrough can become a breakdown.
🕯️ Real Cases: What Happens When Retreats Don’t Screen
These are actual cases gathered from Reddit, public police records, and who have reported incidents to Best Retreats:
- A U.S. woman had a seizure and was hospitalized in Peru after concealing SSRI use
- A man in Colombia died from cardiac arrest after combining ayahuasca with stimulants
- A European guest experienced psychosis for months after mixing ayahuasca with Adderall and marijuana
These were not “bad people” or “bad shamans” – just situations where irresponsible people were not properly screened.
✅ What Safe Retreats Do Differently
The best ayahuasca centers protect guests by:
- Requiring a medical intake form with full medication disclosure
- Offering pre-retreat tapering plans with licensed professionals
- Clearly banning certain drugs and conditions
- Employing onsite medical staff or having emergency protocols
- Providing mental health screening, not just physical
At BestRetreats.co, we verify these safety protocols and flag centers that skip them.
🧾 Must-Ask Questions Before Booking
Ask your retreat these five questions:
- Do you screen for medical and psychiatric contraindications?
- Will a medical professional review my form or meds?
- What is your emergency protocol if something goes wrong?
- Are SSRIs or benzos allowed – even if discontinued?
- Do you provide pre-retreat support for people coming off medications?
If they hesitate or redirect the topic, consider that a major red flag.
🤔 Why Fake Reviews Can Be Dangerous
Unfortunately, glowing reviews alone won’t reveal these risks. Many centers suppress negative stories, and guest reports even on TripAdvisor or Google may omit medical incidents due to shame, NDAs, or removal.
That’s why we don’t rely on 5-star hype. We collect sentiment from across the entire internet and look for the negatives – and we welcome user-submitted incidents anonymously.
🧠 Final Takeaway: Your Health Is the Foundation of Your Journey
Ayahuasca can be life-changing – but it’s not without risk. Especially in unregulated environments, your safety is 100% your responsibility.
Before you book, do your research. Check verified safety protocols. Ask A LOT of direct questions. Use platforms that prioritize transparency over marketing.
Best Retreats was built to help you do exactly that.
