For Urinary Tract Infection "I'm allergic to amoxicillin, so my GP prescribed this medication. I had nausea and a mild reaction for 3 days. I took the 4th tablet tonight. My face has swollen, rash on my hand, tummy tightness, severe nausea, and a terrible headache. I am flying overseas tomorrow, I need rest tonight."

For Bladder Infection "I actually was given this for prostatitis. The first course I was prescribed had no side effects, but the next time one 200 mg tablet gave me a very painful headache that I could not get rid of using paracetamol, ibuprofen, or cocodamol. The headache lasted for four days. Strange that the first course was fine but not the next."

For Bladder Infection "Started taking this antibiotic for 5 days, twice a day, and the bladder infection is still here. Antibiotic resistant. Yes, there were side effects, but nothing too bad. Headache, some nausea, but manageable. On a different antibiotic now, penicillin, so fingers crossed it works."

For Urinary Tract Infection "I've been on Trimethoprim since May 2024, twice a day, as well as Lymecycline. Only recently I've noticed hot flushes alternating with shivers. I'm not sure whether it's the Lymecycline, Trimethoprim, or chronic embedded UTI I've had since 2022. I got a UTI in 2013, became embedded, and was on long-term antibiotics till 2021. I then got better, and it came back in 2022. I really struggle to find a way out of this after I asked my private urologist if it'll ever fully go away, and the answer was 'we do not know.' I don't know if the symptoms I've got are from the Trimethoprim, but I've noticed when I'm on it, losing weight, chronic fatigue, headaches, dry mouth, body aches, and feeling like you have the flu constantly. I've got a lot of antibiotic resistance due, but I'd rather deal with this for the rest of my life rather than get sepsis again after having severe sepsis in 2016. It is either making the infection lay dormant or treating the infection. Time will tell."

For Urinary Tract Infection "My doctor prescribed me trimethoprim 200 mg for 7 days. I take one tablet in the morning, 3 hours later my stomach feels like it's turned upside down and I feel sick. Then at 4 pm, I take another, then 2 hours later a major headache and feeling sick, fever as well. But a couple of paracetamols sort it out. So now into day 4, and I've noticed pale shiny skin on my face. I will finish the 7 day course, but if I get a UTI again, then I will tell the doctor to put me on a different medication because these tablets have vile side effects. 9 out of 10 people will witness side effects and you have my sympathy."

For Urinary Tract Infection "It cleared up my UTI, but made me feel extremely nauseated and gave me really bad headaches. I got prescribed it last year, though, without any side effects, so I'm not really sure what that's about."
