U.S. staples like Sudafed<\/a> and Benadryl<\/a> are banned or strictly regulated in a number of countries, making preparation essential for hassle-free travel. Some countries even require special permits or advance approval for common medications. <\/p>\n Here are some OTC drugs you may not think twice about packing for your next trip abroad, but could require a doctor’s note or previous preparation for smooth entry. <\/p>\n Sudafed and Pseudoephedrine restrictions<\/p>\n Pseudoephedrine, the active ingredient in cold decongestant Sudafed, is prohibited in destinations such as Japan and Mexico. Bringing it in without awareness may result in a seizure at customs<\/a>. <\/p>\n Codeine: A controlled substance abroad<\/p>\n OTC medications containing codeine, commonly used in cough suppressants or pain relievers, face strict restrictions in multiple countries. For instance, the UAE, Japan, Greece, and Indonesia all consider codeine a controlled substance and may require prior approval or a doctor\u2019s note to allow entry. <\/p>\n open image in gallery<\/p>\n Benadryl is restricted in places like Japan and Zambia (Getty Images)<\/p>\n Benadryl (Diphenhydramine) May Be Flagged Internationally<\/p>\n The antihistamine diphenhydramine, present in Benadryl, is restricted in places including Japan and Zambia.

This can create more of a headache when navigating questions than the medications are meant to help,\u201d Quinn English of FreeQuinnt Flyer<\/a>, told Travel and Leisure<\/a>.<\/p>\n open image in gallery<\/p>\n Pseudoephedrine, the key ingredient in Sudafed, is banned in Japan and Mexico (Getty Images)<\/p>\n \u201cAlways travel with the original prescription bottle on your person so they can be easily examined and can help answer immediate questions related to the condition,\u201d she added. <\/p>\n Traveling with a written copy of your prescriptions and\/or a doctor\u2019s note is also suggested.
