Amphetamines - Reactions with Other Drugs or Substances

Reactions with Other Drugs or Substances

Amphetamines are dangerous drugs. The dangers increase when they are taken with other addictive substances. Amphetamines are frequently combined with other drugs to prolong or add to the high they produce alone. Caffeine is one substance that is known to add to the effects of amphetamines. When combined with alcohol, "amphetamines have the potential to produce unprovoked, random, and often senseless violence," noted Murray. Amphetamines raise blood pressure, so they should not be taken by people who are on medication to reduce their blood pressure. In addition, the drug should not be taken with over-thecounter cold medications or with certain antidepressant medications.
