your partner does need a visa to be able to enter the country. if your employer can issue a business visa for him, and u on the work visa, then you can come together. but if you're sponsoring him, then you have to come first, then process the family visa for him -- if you're married that is.

perhaps you can bring a few supplies of pills for a month, and your husband can bring some more when he comes to join you. by that time, you would have already spoken to several pharmacists here.

good luck !
