Drugs such as ecstasy, cocaine, speed and heroin, when taken together with HIV medication, can lead to dangerous interactions. Some HIV drugs intensify the effects of the other drugs, increasing the threat of overdose - in some cases, this has even led to death.
So-called party drugs and heroin can also cause or increase psychological problems such as sleeplessness, depression, anxiety or confusion, especially when these problems are side effects of the HIV therapy. Damage to the nervous system caused by HIV or by HIV medication can be made worse by other drugs.
The German AIDS service organization offers extensive information about the effects and interactions of illegal drugs at www.hiv-drogen.de.
