DCL says medications in their original containers. Take that as a warning. Below is a summary letter from US Customs regarding traveling with medications requirements including what is needed if medications are not in their original container. Regardless of what anyone says regarding their experience of not using original containers it means nothing if you happen to be the person that US Customs decides to stop and check. An explanation of "I know others don't use original containers" will not be a valid excuse. It really comes down to your risk comfort level and understanding that should you get stopped by Customs and checked you should be prepared for whatever consequences that entails. All it takes is running into that one US Customs Agent that decides he/she is going to do random checks. Maybe it is someone who is having a bad day or maybe it is someone who is new to the job and is so eager to do well that they will follow all the customs rules "by the book".
While the letter below discusses traveling with medications it does not specifically mention cruises entering the US but I think it is implied the key is entering the US with medications regardless of the mode of travel.

Prescription medications should be in their original containers with the doctor's prescription printed on the container. It is advised that you travel with no more than personal use quantities, a rule of thumb is no more than a 90 day supply. If your medications or devices are not in their original containers, you must have a copy of your prescription with you or a letter from your doctor. A valid prescription or doctors note is required on all medication entering the United States.
The U.S. Food & Drug Administration (FDA) is responsible for pharmaceutical admissibility determinations. If you have any questions as to whether a specific pharmaceutical may be imported into the United States, visit the FDA's
