Benadryl vs Zyrtex In your opinion, which is more effective, Benadryl or Zyrtex for allergies? Mocha has been on Benadryl twice a day for about 2 months. I recently switched to Zyrtex becasue its only given once a day and last for 24 hours and it covers indoor and outdoor allergies. I'm considered about the long term effects of both of the meds. Any thoughts . . . ? |
