International Travel with Controlled Substances - Guidelines for Travelers

Travelers entering Israel may carry up to a 90-day supply of medicines except for narcotic drugs or psychotropic substances, even if a product is not considered a controlled substance outside of Israel. Travelers traveling outside of Israel who carry medicines must check the laws of their destination country as to medicines, particularly those classified as narcotic drugs or psychotropic substances.
