Zyrtec vs. Accutane

Hey all,

I'm a 24-yr-old female struggling with acne for 13 years. So just started my accutane treatment 2 weeks ago and my derm prescribed me 10mg accutane along with prednisolone 10mg to reduce the IB. Over just 4 days of prednisolone medication, my face has been swelling like I have been eating too much lately. My co-workers kept asking me why and that was so embarassing.

So would that be okay if i start tapering off the prednisolone and taking the OTC zyrtec to come by the IB or any kind of inflammation caused by taking accutane? Anyone please advise, really appreciate it!!
