"I had a very bad experience with this antibiotic. I totally lost my mind. All the usual levels of anger, fear, and hurt were multiplied by 100. Thoughts totally dark, with my heart pounding like crazy. I ended up smashing plates! I couldn’t sleep. I saw the reviews from other people. Stopped the antibiotic, and after a day, I feel shattered but myself again. This could have been so dangerous. Please, if you experience something similar: you will be okay, just stop taking this antibiotic. After reading other people’s reviews, this drug should really be taken off the market. It could be dangerous, especially for people already with vulnerable mental health. All the best to you."

"I wish I had read the damning reviews on here prior to taking this. Was given 200 mg twice a day for 10 days. After the first tablet, I felt a little numb, I took my second at bedtime, and that’s where the complete unraveling of my physical and mental well-being started. I woke up literally unable to move, my body was so weak, I had severe kidney pain and shooting pains up my spine. I felt really weird and very, very scared. I tried to get up and collapsed, I shook uncontrollably and started to burn up. The anxiety and panic attacks were so debilitating I thought I had had a mental breakdown. I lay in pain, rocking and muttering for hours in complete panic, not knowing what to do or how to make it stop. A friend came over and looked after me for hours while I just cried uncontrollably and apparently talked about some really strange things! Scary doesn’t even come close to it, I actually thought my life was over. I will never take this again, not if someone paid me a lot of money to do so. Ban it!"

"Was prescribed 200 mg twice a day for UTI & possible kidney infection for 5 days. Not even an hour after the 1st pill hit my system, I was throwing up, shaking, agitated, having horrific thoughts, anxiety, couldn't stand, and had such bad fatigue I could hardly lift my head off the pillow. Also had facial bone pain along my jaw and cheekbones. After my 3rd day (today, 4th March 22), my doctor advised to stop & switch to a different antibiotic as I am just not coping on these. I'd rather sit in the bath for hours on end drinking cranberry juice and water to flush out the UTI than ever take these again!"

"Given 200 mg twice a day for 2 weeks. The UTI cleared up okay, but I had severe anxiety and intrusive thoughts after 2 days. It was one of the worst 2 weeks of my life. I will NEVER take this medication again. (3 days after the 2-week course of medication was completed, my thinking returned to normal, and my anxiety disappeared.)"

"This antibiotic, trimethoprim, is good for treating UTIs, but gives awful side effects. Had 3 days' worth of these, and although it cleared up the infection, it came with some unwanted feelings. Worse side effects were migraine-type headaches, fatigue, shakes, nausea, and racing heart. Absolutely awful, wouldn’t want to take these again. Thank God it was only 3 days!"

"OMG, I have never experienced an antibiotic so awful in my life than trimethoprim 200 mg twice a day for seven days. Pains, anxiety, migraine, shortness of breath, and tearful. Hot flashes. I nearly fainted, I felt so ill. Stopped them Sunday and hoping I feel myself again soon."

"I took a three-day course. From day 2, a bad headache, weariness, and aching. Had to sleep on day 3. After stopping, was ill for 2 days with exhaustion, terrible headaches, toothaches, and pain throughout my body. I will never take this dangerous drug again."

"Had trimethoprim for a UTI, one a day. The first night, I had the most horrible acid reflux all night, woke up the next morning with the sorest throat in the world and about 2 hours of sleep. Then, after night 2, I experienced a massive headache where I couldn't put my headset on to work, and I felt so tired. By night 3, I was a bit itchy on my arms, and a rash developed, but the UTI had gone by then, so I stopped treatment. If a doctor recommends alprim again, I'm going to say no."

"I got prescribed the medication for a really bad UTI, and I was so terrified to start them. I kept reading so many bad reviews of other people with really bad side effects. I delayed my prescription for like 2 days until the pain got so bad I just took them. It’s day 2 now of a 3-day course, and I honestly feel great! My pain started going down within the first 12 hours after taking the first pill. I've had zero side effects. I’m so happy it worked for me, and it might also work for you! The benefits far outweigh the risks. If I hadn’t started my course, then I probably would’ve ended up in the hospital. Don’t let the comments freak you out!"

"I was given 4 days of trimethoprim for a UTI. After the first tablet, it brought on intense anxiety and panic attacks, and I couldn’t sleep. I stopped it after the second day, and it went away. It was awful, will never touch it again!!!"

"Was prescribed a 3-day course of Trimethoprim here in the UK for a UTI (I have a history of these infections). I managed to complete the course, and it does appear to have resolved the infection, but by day 2, I had developed a crippling headache that nothing would shift-so bad it sometimes hurt just to move my head. Don't know what I would have done if the course had been longer. I advise caution, as the headache is deeply unpleasant."

"After several bouts of urinary tract infections while awaiting prolapse surgery - bladder unable to void efficiently - I experienced extremely severe mouth ulcers on each occasion, lasting three weeks. I was told this was probably because I was 'run down.' However, most recently, half an hour after taking the first dose of Trimethoprim, I experienced intense burning of my lower lip, accompanied by extreme swelling. Recognizing this as the start of the severe mouth ulceration I had experienced previously on numerous occasions, I informed my doctor, who immediately prescribed antihistamine and told me to stop taking the Trimethoprim, substituting another antibiotic."

"I'm on day 3 of this medication, and before reading these reviews, I have had a migraine that won't go away, shaky hands, trembling, paranoia, dry mouth, nausea, and the itchiest skin. These are all of the symptoms I've read of people that have taken this, it's actually scary, worth reading up before you take something new."

"This antibiotic has left me really unwell. I was prescribed 200 mg 2x daily for 3 days. I only took 3 tablets (1 a day). Firstly, felt like my kidneys had been battered, followed by severe stomach pain, extreme shivers and anxiety, also bad insomnia! Getting sharp shooting pains (like an electric shock all through my body)! Bad muscle aches as well. Warning! If you suffer mental illness, please avoid, as these pills really heighten everything. No more for me, it is an awful drug. Not forgetting headaches, facial pain, and horrendous nausea. I feel for all the patients experiencing these unwanted side effects. It's been 1 and a 1/2 days since stopping them, praying this will all pass real soon. In my opinion, they should be taken off the market pronto. Hope doctors realize what toxicity they cause. I never will take these again, not worth the suffering."

"My GP gave me 3 tablets of Trimethoprim Mylan. I wish I had never taken them, the side effects are not worth it! The headache was so bad it just didn’t go away, unable to do anything, constant nausea, chills, and shaking. I cannot believe they can market this drug without extreme warnings. There was no pamphlet inside to notify of side effects. I am deeply upset about this, and I won’t ever touch it again. I am not exaggerating. Thank you."

"I’m on a 3-day course with these tablets for a UTI. Since taking them, I’ve had the worst throbbing headaches. I’m dehydrated and can’t seem to quench my thirst. I’m exhausted (really fatigued). I have a stiff neck and a sore throat. I’ve taken these in the past and never had side effects like this. They have changed somehow."

"Took this medication (trimethoprim) for UTI. Never again. Had a burning sensation in my stomach and awful pains. I was trembling and had the worst headache on day two that lasted all day. Nothing would shift it. By day three, I was so fatigued I could barely move. Should have stopped this tablet on day 1."

"Had a UTI that turned into a kidney infection. I get chronic UTIs and have become resistant to many antibiotics. Day three of 300 mg, once a day, and my kidney infection cleared. Woo! I was left with a bladder infection still for the rest of the week. I started taking biofilm defense, and the antibiotic started to do its job properly. I’m guessing biofilm is the cause of my chronic UTIs. Feeling heaps better with this combo. Side effect is that I have extreme fatigue when I take this."

"Day 3, and this drug has made absolutely no difference at all. I recall this exact same thing happening last time I had a UTI (a while ago now), and I was changed to a different antibiotic. My experience has not been a good one at all."

"After taking two tablets, I went into anaphylactic shock, had to call paramedics, inject adrenaline, and spend 18 hours in Accident and Emergency. Just beware of this, I had never taken trimethoprim before. Dangerous drug."

"Prescribed 1 Trimethoprim at night for a long-term UTI, and all it has done is made the UTI symptoms worse. I'm fine in the day, but at night, I can't sleep because of the burning/tingling sensation in my girly bits. The pain is indescribable. I'm seeing my GP today, so I'll get them changed. Worst antibiotic I've ever had."

"I had a UTI and was prescribed Alprim (trimethoprim), 300 mg one at night. On the third day, I developed a severe rash on both lower legs and feet. I have taken it for 5 days, and I am not taking the last two. I have taken photos to show my doctor, definitely seems like an allergic reaction of some type."

"Got 200 mg to be taken twice daily for a UTI. Night one, I started to vomit and had zero energy with an indescribable migraine, I put it down to the UTI making me poorly. Over the next few days, I started to have my muscles cramp up massively, my arms and legs would not move, and the energy to move them was too much. It also caused unbelievable acid reflux, I could not eat for a week, literally zero appetite. Lost a lot of weight. The last two days, the anxiety, insomnia, and panic attacks set in. This is when I checked on here for reviews and realized I wasn't the only one. It cleared the infection, but boy, what I put down over the week was something else, please find an alternative if you can."

"Cleared up the UTI, but 5 weeks after taking the final tablet, I'm still having side effects. First noticed that I had a sore throat and stiff neck after taking tablets for 5 days (was given a seven-day course) but did not make the connection with taking antibiotics. Continued to take medication. I then developed a sensitive scalp, neck pain got worse, and on-and-off headaches plus shoulder and back pain. Felt awful. I was on holiday at the time, and it seemed to ease after about a week. Reported to my GP on returning to the UK. Now, 5 weeks later, on holiday again, neck pain, sore skin, and head pains are all back. Hope this helps others. Not sure if I should seek medical attention or just hope problems go away with time."
