@jessgibs25 , there should be no problem travelling with the Aubagio. Take it in your hand luggage and obtain a letter of declaration from your supplier, just in case of any questions at airports. The only other thing to consider is the storage requirements of Aubagio :- "Store at 68°F to 77°F (20°C to 25°C) with excursions permitted between 59°F and 86°F (15°C and 30°C)."

Ah yes Caribbean travel with prescription drugs is easy in my experience. Get the letter just in case. But getting a prescription actually over there could be a challenge with something like an expensive MS drug which will have to be shipped in MS not a common thing and Antigua although has quite good medical service it is nevertheless a small island but I’m guessing you will be travelling with your few months supply However keeping things cool not as easy. Will your hotel have air con or a minibar or are you visiting family ? Enjoy Antigua you lucky thing. Vincy 💚 🇻🇨
