Neither Maxitrol or tobradex are good choice for allergic conjunctivitis. Both often irritate the eye and have harseh preservatives in them. You would best use a good artificial tear: Systane, Blink, Refresh, Soothe and something for allergies like Patanol or Pataday. If your allergy is bad enough to require a steroid then lotemax, or pred mild would be better choices.
