Hi there, I was experiencing some uti symptoms at the end of last week and used the boots pharmacy service ( impossible to get gp appointment) and was prescribed a 3 day course of Nitrofurantoin . I took it and within a day started feeling really nauseous and low energy but thought maybe I had a tummy bug .the nausea has got worse and worse and last night my heart was racing and I felt really dizzy and disoriented ( felt like I was falling whenever I lay down ) That’s eased slightly but I still feel really sick and quite woozy and not myself at all , Has anyone experienced something similar and if so when did it ease? I stopped taking it yesterday morning as felt like it wasn’t agreeing with me .
