When checking interaction based on authoritative sources Drugs.com, Rxlist.com, Webmd.com, Medscape.com there are contraindications or side effects that may cause harm or increase the negative effect from drug interaction with food or lifestyle.

Consumer:

Terfenadine is no longer on the market in the US. Do not take terfenadine with any other food or medication.

Professional:

CONTRAINDICATED: The consumption of grapefruit juice has been associated with significantly increased plasma concentrations of terfenadine. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall induced by certain compounds present in grapefruits. Terfenadine in high serum levels has been associated with prolongation of the QT interval and development of torsade de pointes, a potentially fatal ventricular arrhythmia.

MANAGEMENT: Due to the risk of cardiotoxicity, patients receiving the drug should be advised to avoid consumption of grapefruit products. Loratadine, cetirizine, and fexofenadine may be safer alternatives in patients who may have trouble adhering to the dietary restriction.
