my dad 79 years old high bloodpressure diabetic  just yesterday found out had cellulitis on keflex 500 already had 6 pills has a pain in left shoulder took bloodpressure 240 over 150 had squad come went to 204/150 want to know if keflex can raise it
Hi and thank you so much for this query.I am so sorry to hear about this cellulitis. Keflex cannot cause this sudden and alarming increase in blood pressure. I will suggest that you get your father to the emergency room because these numbers are very high and need immediate attention to avoid related complications like stroke, heart, kidney damages, etc.Cellulitis in diabetics should be approached with full force because of the fear of severe complications. If the  improvement is not remarkable withing 48hours, please talk to his treating doctor.I hope this helps. I wish you well.Dr. Ivo, D.
