Are Medicines Sealed In Pack Sent In Mail Safe To Use?

I have ordered azithromax online.. and after receiving the medication in the mail it didnt come in a box or anything. it was just the Tablet packets. I want to know if the medicine is any good its sealed in a gold pack and is marketed by Signature Pharmaceuticals Ltd. It also says its manufactured in india by a company called HAB Pharmaceuticals.. I can send a pic if necessary.. the pack looks legit and sealed like any other medication. The tablet is a circular orange peachy color with no writing on it at all like numbers or letters or anything.. Thanks for your time!
