Hello.
Yes, I take phenergan regularly, often every 6 hours as needed. While I have been prescribed other drugs for nausea such as Zofran and Reglan, these 2 drugs come with unpleasant side effects, and my doctor did advise me that Reglan has been known to cause neurological damage.
I take phenergan because of a liver disease. My pancreatic and liver ducts are dilated. Nausea is a frequent side effect of this problem.
As a side bar, I too get frequent UTI's and the antibiotics are hard on my stomach. Taking a probiotic along with the antibiotic has proved helpful. But, I do know that frequent use of antibiotics can create long term problems with one's stomach. I am still recovering from my last course of antibiotics that were given 2 months ago. It is not unusual for this to happen.
I am so sorry about your mother, and I hope she is feeling better soon. Check out some probiotics for her.
I wish you both well.
