Possible reaction with antihistamine

I have been taking Zirtek an antihistamine for many years for urticaria. Having a severe cold I took 2 Bechams Flu Plus before going to bed which contain Phenylephrine Hydrochloride. When I got up during the night to get a drink of water I passed out. I then passed out twice more. I was taken to hospital where they concluded that Phenylephrine hydrochloride was an antihistamine and I had therefore overdosed on it. All the tests they did were clear for anything else. Could this be true? I am taking no other medication and am very healthy otherwise.
