Will anything happen to me if I start taking Gripex Max while taking Prefaxine?

Yes, you put your health at risk for serotonin syndrome. Serotonin syndrome is manifested m.in confusion, agitation, fever, sweating, ataxia, hyperreflexia, muscle clonic seizures and diarrhea. This condition is distinguished by the so-called triad of symptoms, which includes: 1. Vegetative disorders, i.e. an increase in blood pressure, fever, diarrhea, vomiting and mydriasis. 2. Psychiatric symptoms, consisting of anxiety disorders, feelings of anxiety and confusion. 3. Neuromuscular ailments, i.e. recurrent cramps, pain and increased muscle tone. If you are struggling with a cold, you can safely use Paracetamol, but without the additional ingredients that Gripex Max contains.
