Brief Answer: Valsartain in Exforge is the probable cause Detailed Answer: Hi and thank you so much for this query. I am so sorry to hear about this swelling of the face and lips that you have described. I hope we get to figure out the exact cause of this and propose some real solutions to you. After a thorough review of your symptoms and the medications, the most likely cause of this is exforge. Exforge contains as one of its active components valsartan which has been well documented to cause these symptoms. This is generally referred to as angioedema. It is a concerning condition and needs to be addressed. Depending on the severity of your symptoms, your doctor may want to change this class of medication to another which is not known for these similar effects. For this reasons, I will like you to report this to your treating physician and get him to assess and do the appropriate changes. What breathing disorder do you have? This is because this same drug can cause some swelling in the airways that can be responsible for breathing difficulties. If the cause has not been clearly identified, then your physician should consider this as one of the possible causes. I hope this addresses your query fully. Thank you so much for using our services and please feel free to ask for clarifications if need be. I wish you the best of health. Dr. Ditah, MD.
