Can I be taking any kind of anxiety medication and donate plasma? Will there be some sort of drug test? I just want to make sure I don’t schedule an appointment and get turned down because of any medications I’m taking

Do not "just not tell them" because it could be a danger to you to be donating and you wouldn't know because you didn't inform the nurse. I personally don't think that an anxiety medication would exclude you from being able to donate, but you can call and simply ask a nurse if the medication you take will exclude you from donating.

There is no drug test but it is good to be honest about what you're taking. You are allowed to take some medications and donate. You won't be deferred for that but you will be deferred for LIFE if you lie about it.. It's better to have the appointment and talk to the nurse and find out for sure then to assume you won't be able to. Hope this helps :)

Just dont tell them
