Nyquil: Sinex or severe cold and flu would cause a racing heart, both contain phenylepherine, a decongestant, that is not recommended also for people with high blood pressure, please read the labels carefully. Benadryl (diphenhydramine) and other nyquil preparations not containing phenylepherine wouldn't cause such, good luck
