Common types & examples
Pain / fever relievers
Widely allowed, but carry in original packaging in case of questions.
Decongestants (pseudoephedrine)
Restricted or banned in some countries, including Japan and Mexico, because of misuse concerns.
Cough medicines (codeine/dextromethorphan)
May contain ingredients treated as controlled substances in some destinations.
Antihistamines (e.g. diphenhydramine)
Routine in many countries but restricted in a few; check before you travel.
Stomach remedies
Antacids and anti-diarrheals are generally low-risk but still best kept labeled.
Why it's regulated
Although sold freely at home, some OTC ingredients are controlled substances or precursors elsewhere and can trigger public-health and drug-control rules. A medicine that is over-the-counter in one country may be restricted or illegal in another.
Typical allowance
Provisional only: personal-use quantities are generally accepted, but specific ingredients (such as pseudoephedrine or codeine) face country-specific bans or caps regardless of amount; verify with your destination.
