I was on keflex 500 mg every 8 hours. After four doses, I experienced dizziness, difficulty breathing and syncope. I also had palpitations, high blood pressure, ice cold hands & feet and continued to have dizzy spells while lying flat on my back. None of the labs done in the ER could explain this. It's the keflex. I have taken penicillin before without any adverse reaction. I will never take Keflex again.
