FDA Releases Warning About Mixing Grapefruit Juice, Medicines

Posted 24 February 2012 | By Alexander Gaffney, RAC 

The US Food and Drug Administration wants you to know that grapefruit juice is great for you-except when it isn't. The agency sent out a press release to consumers on 22 February warning them that taking the fruity drink along with medication can cause dangerous side effects.

The "juice increases the absorption of [a] drug into the blood steam," warned Shiew Mei Huang, acting director of FDA's Office of Clinical Pharmacology. This can cause adverse events by causing higher concentrations of consumed drug.

FDA noted that certain drugs are known to be affected by grapefruit juice, including statin drugs, blood pressure drugs, organ transplant rejection drugs, anti-anxiety drugs, anti-arrhythmia drugs and antihistamines.
