that is a pill form anti-histamine. and i would recommend if you juice especially with orals you definately run liver support.
as far as cortico steroids you should not even be lifting weights if you are on those unless you want to damage your joints, tendons, and ligaments permanently. not even a matter of juicing on it. also you will likely gain a ton of weight on those. i know people who went from 150 pounds to 250 on those. doctors should never prescribe those unless its for very short time frames and you taper them down. they are not to be played around with. you are basically shutting off your bodies response/acknowledgement of pain, not smart when you are throwing around weights.
you need to avoid allergens yourself including foods, pet dander, etc. get a HEPA vacuum.. don't let your pets in your bedroom. if you are allergic to pollen keep your windows closed, don't hang clothing outside, etc. these are little things that will help. i have allergies myself and i will be damned if i have to take pills for the rest of my life.. fuck that.
