It is not recommended since the combination can increase side effects such as lethargy/drowsiness or confusion. In s senior pet, this could be risky. Contact your veterinarian in the morning to discuss your concern further as well as options. If Winston is having a severe allergic reaction, consider a visit to the nearest veterinary ER.
