The combination of Ayahuasca (an MAOI ) and SSRIs is potentially life-threatening. Any medication which has an effect on the serotonin system, such as SSRIs can induce serotonin syndrome in conjunction with Ayahuasca. Normally you will not be able to attend the ayahuasca ceremonies, if you haven't stopped taking the medicine three weeks prior to the retreat.  That being said you are still able to attend the retreat and we will also discuss case by case with our medicine people. So do not hesitate to contact us. The most important factor is that you are 100% honest with us and give us a full health & medical statement about yourself.
