Interactions with Foods and Other Compounds
Food
Food slows the absorption of loratadine and also increases the total amount of the drug
absorbed.1 It is recommended that loratadine be taken on an empty
stomach.2
Alcohol
Selective antihistamines, including loratadine, may cause drowsiness or dizziness, although it
is less likely than with nonselective antihistamines.3 Alcohol can intensify
drowsiness and dizziness, increasing the risk of accidental injury. People taking loratadine
should use alcohol only with caution.
