my wife took two benadryl to help her sleep then found a nighttime cold medicine. would it be safe to take both? . my wife has a cold causing her sinuses to be stopped up and a sore throat. we were trying to find the cold medicine but she gave up and just took two benadryl to help her sleep before i found the nyquil multisymptom cold medicine. would it be okay for her to take the nyquil too or is it better to let her sleep off the benadryl first?
no this could cause heart palpitations and increase her blood pressure.
