62 yr old male lactose intolerant which causes asthma symptoms. Meds: allopurinol 300mg BID, Lopressor 25 mg BID, MVI, Vit K 400mcg BID, St John Wort one cap QD. I took metamucile one table spoon for two weeks. Would this cause anelectrolyte imbalance? Symtoms: I wear hearing aids, it seemed like the volume was turned up much higher than the aids would go. dizziness, blurred vision, weakness, thought I might pass out.
