I began taking Lisinopril back in early February. Within days, I developed a horrible cough, that was so severe, it induced vomiting - not food, just a clear sticky mucous. The vomiting happened 5-6 times per day following a stressful coughing bout. I saw my PCP, was diagnosed with a "bad cold", prescribed cough medicine and inhaler and sent on my merry way. The vomiting was happening while I was driving or sitting at my desk at work; it would come on so suddenly that I rarely had time to get to the bathroom. When this didn't clear up after several weeks, my PCP took me off the Lisinopril for about 10 days, but there didn't seem to be any change in the symptoms, so went back on the Lisinopril. I have had Abdominal, ENT, and Brain CT Scans to investigate the cause of this problem as I am a breast cancer survivor. Thankfully, the scans were clear. I have also had an Endoscopy, and have seen an allergist. I also developed a metallic taste in my mouth that was horrible. After doing research on the Internet and speaking with others who have also experienced similar symptoms, I contacted my PCP and took myself off the Lisinopril in mid-April. The coughing has been reduced, and the volume and frequency of the vomiting mucous has reduced as well. Here I am seven weeks off the medication and I am still have side effects. One of my doctors said that it could take several more months to see a complete improvement. Had I been aware of the potential for these side effects I would have never gone on this medication in the first place. I do know folks, however, that take Lisinopril without any side effects, so it works great for some. My BP is now creeping up again, and I am not sure what replacement drug will work best for me.
