Personally, I'd get whatever else you can get such as Beta-blockers, benzos, Painkillers even if they aren't a necessity since people have gone without those but I'm not those people so any one of those meds may come in handy with regards to making things easier, everyone reacts to symptoms differently so certain meds like Beta-blockers, for example, help out since I'm sure those who've never experienced tachycardia like I have will be panicked by that.
So, besides the AEs, nothing is strictly imposed but you might as well get whatever else you can.
