I was recently in the hospital for a Pulmonary Embolism, Pneumonia, and finally a drug reaction that lead to inability to focus on thoughts initially, then followed by inability to speak or move. I believe it was from the combination of a Beta-Blocker Metoprolol and the nebulizer Atrovent which is a Beta Antagonist. BP in the 200 s / 150 s HR tachy. But, looking through list of other meds, Chlorpheniramine-Hydrocodone does cause the lack of focus of thoughts also. The other symptom before I couldn t communicate was burning in my lungs and bronchospams. Have you seen this type of reactions before? How common?
