For Bacterial Infection "This was not right for me. I had a severe reaction while taking this and had to go to the emergency room. Racing/irregular heartbeat, nausea, shaky, legs felt weird, red blotches, slurring speech, red eyes, feverish and generally felt very unwell. "

For Kidney Infections "Took this medicine for a horrible horrible HORRIBLE kidney infection. Worked within 2 days and cleared up all of my symptoms, which was such a relief. I was told to finish off the bottle by my doctor, and the next day I developed a horrible case if the hives. I stopped taking the medicine immediately, but the hives stuck around for another 3 days. What a miserable week! So, Bactrim worked wonders for my kidney infection, but little did I know I was severely allergic to it. Take with caution."

For Urinary Tract Infection "I'm currently on bactrim, first day taking the medication and I saw an immediate difference. My Uti's are horrible, I'm normally awaken from my sleep, as they hurt that bad. I'm up for hours on hours sitting on the toilet due to the urge. Bactrim is helping this a lot. Also I see a lot of people are feeling sick while taking this medicine, my doctor recommends that I take the medicine with food, hope this helps you guys in the future if you're experiencing sickness."

For Kidney Infections "I was a bit of a moron and let a UTI go for too long. I had pain on and off for a few months in my back. Pee was cloudy, frequent urination..all that good stuff but two days ago I woke up and felt absolutely terrible. I was so nauseous, couldn’t eat anything, awful headache, chills and the worst back pain I had ever felt. I went to Dr and she wrote this for me. I took two pills yesterday and already today I feel a 100x’s better. I don’t believe it is for everyone obviously due to the mixed reviews and my mother had taken it before and it had awful effects on her as well but I do believe it’s worth trying because for me it’s been wonderful. I couldn’t even bend over yesterday and today all I have is slight dull pain in my back.Worked perfect"

For Acne "I have had severe acne since I was 10 (I’m 35 now). I have very oily skin, & get cystic acne usually around the time of my period. I also have blackheads & small breakouts occasionally. I’ve tried every Rx out there, including Accutane once in my 20’s & again in my 30’s. It’s very effective but unfortunately it’s not a complete cure for me. When my cystic acne flares up I use Bactrim and it’s amazing!! It clears my skin right up. It does have a very drying effect (which is fine since I’m so oily!) but it makes my lips chapped too. I only use it for 7-10 days a month. If I use it longer than that my lips start to peel & crack. So I take a break & use it at the first sign of trouble. It’s worth noting that I’ve tried doxycycline & minocycline with no results besides an upset stomach. So if you are considering taking Bactrim, do it! I use it with Retin-A."

For Urinary Tract Infection "I wanted to leave this review to help anyone worried about taking this. I'm in my late 30's and get UTI's often. They seem to come anytime I have intercourse and I try to combat them with D-Mannose. I typically have to get an antibiotic twice a year. Bactrim is my drug of choice in combination with pharmaceutical pyridium. Bactrim does not cause the gut issues that Cipro does and I find it to work quickly. The key to bactrim is to take a pill after you eat with a full bottle of water. In between doses, take a probiotic. So morning bactrim-lunch probiotic-dinner bactrim-bedtime probiotic. There will be obvious relief of symptoms within 24 hours and you need to complete the entire 7 days. In addition, if you are going to be in the sun, wear long sleeves and a hat. If you cannot cover up, remember the 1 to 3 rule. When on sulpha antibiotics, 1 hour in the sun is equivalent to 3 hours in the sun. Take AZO or pyridium the first 2 days to relieve urge/pain."

For Acne "I cannot believe how amazing this medicine has been for my cystic acne. I have tried monocycline, doxycycline, prescription topical creams, NOTHING worked. I finally decided to ask my doctor about Bactrim. I have been completely cyst free since October. This is a record amount of time for me to have NO cysts! I have had, maybe three pimples. I've had no side effects. The monocycline gave me horrible joint aches (to the point where I'd almost cry they hurt so bad). So far I have had absolutely NO side effects. It's wonderful!"

For Urinary Tract Infection "I've taken my fair share of medications for UTIs and so far this one seemed to be the most effective as far as relieving symptoms quickly. My doctor prescribed me to take two pills a day for 10 days. I felt relief from UTI symptoms as soon as the 2nd or 3rd day. That being said, it has some nasty side effects. They say you can take it with or without food and I'm guessing that because it makes your stomach feel horrible either way. I've experienced diarrhea, painful gas and bloating, and nausea, since the first day of taking it. From my experience this can usually be expected with strong antibiotics. My advice would be to take a probiotic to help counterbalance! I've done it before and it helps me."

For Urinary Tract Infection "Day 1: Prescribed 1 pill twice a day for 7 days. The medication seemed to be working and I was urinating like normal. Day 2: That night, I ended up experiencing terrible pain on the inside and outside of my vagina such as: burning, itching, redness and swelling. I thought it could be a reaction but it wasn’t sure. Day 3: That morning, I ended up experiencing the same terrible pain but it was more severe. At this point, I could hardly move, sit or stand without it hurting. It felt like ulcers on the inside and outside of my vagina due to the terrible burning sensation. That night, the pain got even worse. I ended up having chills and body aches, possibly a low grade fever. Day 4: I stopped taking the medication. I decided that this medication is not worth the symptoms and advised to my doctor that I would not be continuing the medication. *If I could rate my symptoms on a scale from 1-10, I would rate it at a 15. I will NEVER take this medication again."

For Urinary Tract Infection "It's currently 12:30am, and I'm wide awake on a school night typing this. I didn't exactly have all the symptoms of a urinary tract infection, but always have the urgency to pee. I went to urgent care, and the doctor prescribed me Bactrim. I've been on it for 3 days (today will be my 4th), and I have yet to see results. According to some of you, it doesn't start working until the 5th day, which still gives me hope since the doctor told me it would work within 2 days. What I have been seeing is nausea, diarrhea, shakiness, insomnia, extreme headaches, and loss of appetite. I really hope this works. The constant urge to pee pretty much ruins what little social life I have. Having to make constant trips to the bathroom doesn't fit well with football games."

For Bronchitis "Had a bad case of bronchitis and Bactrim was prescribed. Within a day I was feeling better and was completely well in 3-4 days. Amazing! However, my wife was prescribed the same drug for her bout of bronchitis and found that she was allergic to it and had horrible stomach pain. So it's obviously not for everyone."

For Urinary Tract Infection "Irregular heartbeats that "feel" like a panic attack. Weak feeling all over body and loss of strength after doing something simple such as throwing out the trash. Bactrim MAY give you brain fog and feelings of depersonalization-it may also affect your electrolyte levels. Be prepared for possible psychotic effects on your brain and not knowing why you are losing yourself/mind. More importantly, watch for the development of pernicious anemia. Again, this may not happen to EVERYONE but watch yourself carefully while on this drug. This won't cure EVERY UTI. Before you take this, BEG your doctor to CULTURE your urine so that you will be put on the "right" antibiotics. This interferes with your body's ability to breakdown Folate into a useable form and can interfere with your bone marrow WHICH produces red blood cells."

For Bacterial Skin Infection "I'm thinking some of the side effects commented were possibly results of the condition and not the medication. I have MRSA. Of course I have chills because the abscess are a massive infection. One person mentioned organ failure. MRSA entering the bloodstream would do that too. So far so good here- still early on. I was on clindamycin for a tooth abscess. I must have been unknowingly treating a mild staph infection. When the clindamycin stopped the bacteria became aggressive. Now here I am on Bactrim. One sore has lightened in color and pressure within 24 hours. The other sores still hurt, so I took ibuprofen. You won't get headaches if taken with pain/ fever reducer. The clindamycin wrecked my gut but I actually haven't had a hard time with the Bactrim. I've been sure to eat something or drink a glass of milk before taking it."

For Acne "I am 20 years old and have been taking Bactrim since I was 14. Originally I started with a twice daily dose but have since decreased to half a pill every other day. It is not a perfect fix, as I still have to be attentive and wash my face twice a day and occasionally use an acne cream, but otherwise it works quite well. Before starting Bactrim I had moderate but painful acne, and I now only get small infrequent pimples. I am now a pharmacy student and thought I should warn people that extended use of any drug is dangerous. Also, Bactrim is NOT an antibiotic but is a synthetic sulfa drug meaning it is made from chemicals. Some people are severely allergic to sulfa drugs and should be cautious and talk to their doctor before taking this drug"

For Bacterial Skin Infection "I was prescribed this for a nasty spider bite that got infected. The infection started getting better after one day but the nausea is 24/7. I could hardly eat anything and had trouble sleeping because of the horrible feeling in my stomach. Was prescribed 2 pills a day for 10 days. The pills were large."

For Acne "I started taking this a few weeks ago and my acne is almost 100% gone. My skin feels very soft and smooth as well. It is definitely worth a try. I was on Monocycline before for about a year and my acne began to relapse. Once I started on Bactrim my skin was clear again but I am scared of relapsing since it is still an antibiotic. Drink lots of water as well because you constantly feel dehydrated."

For Bacterial Skin Infection "I went to the ER for bug bites that got huge and gave me a rash. At first, they gave me steroid cream and sent me off. Went back few hours later after they doubled in size. They gave me an antibiotic shot and 2 Bactrim pills to take there plus prescription for Bactrim 3x daily. Within 24 hours, the cellulitis was almost all gone. 48 hours, it just looks like light bruising. Thank you Bactrim! However, I do have a bad sore throat now!!"

For Bacterial Skin Infection "I had a very small cut next to my fingernail that turned into a full-blown staph infection (cellulitis. It very quickly (within 24 hours) spread up my finger to my second knuckle. My doctor prescribed 10 days of Bactrim and by the second day the infection began to subside. No side effects that I can think of."

For Kidney Infections "Really effective, but really terrible side-effects. UTI and kidney infection both cleared up quickly, which I'm grateful for, and ultimately that's the point. But I had nausea and vomiting, dizziness, diarrhea, joint aches, itchy skin, sore throat, loss of appetite... I felt way better with the infection than I did on the medication. But it's all temporary."

For Kidney Infections "Took 2 Bactrim daily for UTI after 3 prescriptions of Keflex with no change to infection. Bactrim did cure the persistent UTI but I ended up in hospital and tests showed my kidneys were not working. So was effective cure but serious side effects. After 4 days in hospital kidneys are back to functioning"

For Urinary Tract Infection "I went to urgent care for unbearable pain from a UTI and they put me on bactrim. This made me feel awful. Lots of anxiety and panic attacks, and constantly feeling dizzy like the room was spinning and like I was going to fall down and pass out. Felt very shaky on day 5. Also experienced neck pain and pain in my lower back. Also experienced headaches. It cleared up the UTI but had horrible side effects. I’m someone who also has neurological Lyme disease so my left side of my jaw just goes into spasm when I have a flare up, which is another painful condition I live with and I’ve taken many other antibiotics for Lyme and for sinus issues but I’ve never experienced symptoms like this."

For Urinary Tract Infection "The ONLY side effect I had from this medicine so far is very slight fatigue right after I take it. Had a pretty bad UTI, took the first dose ( 2 a day every 12 hours) and within a short amount of time there was no more burning, fullness feeling, or pain. I take this for 10 days and I am on day 7. And no dizziness, nausea, vomiting or anything. Don't be afraid to take this medicine BUT! EAT BEFORE YOU TAKE IT!! Like a full meal! I think many people aren't doing this and you should."
