Anti-depressants and drugs
Some anti-depressants can interact dangerously with some recreational drugs (including ecstasy, speed, crystal meth, acid and cocaine), boosting levels of the recreational drug in the body to dangerous levels.
A potentially life-threatening reaction called Serotonin Syndrome can also occur, where the brain releases too much of its 'feel good' chemical serotonin. Symptoms include a fast heartbeat, sweating, muscle spasms, shivers, high temperature, feeling agitated and being unable to sleep. Urgent medical help is required in this situation.
If you are prescribed anti-depressants, check with a doctor about any possible interactions with recreational drugs you may take.
