Nitrofurantoin for Urinary Tract Infection "I’m leaving this review for people (like myself) who google EVERYTHING before they try something. I have A LOT of anxiety so reading these reviews made me very nervous about starting this med. I was given cipro 3 days ago for a UTI/kidney infection and spent the whole night throwing up, and pain etc. went back to the doctor and she prescribed Macrobid. It’s been 2 days that I have been taking it and so far, so good. Yes, you have to eat with it or I get mild nausea. I find myself more tired but that’s ok with me...I need sleep! I have been drinking a lot more water (I’m a huge water drinker to begin with) this med makes me thirsty. I’m glad I tried it and didn’t let the reviews get the best of me! I don’t know how it’s working for the UTI because I didn’t have any symptoms other than back pain. It was the urine results that warranted the medication. Everyone reacts differently to medications. So please take these reviews with a grain of salt. Good luck to everyone out there!!"

Nitrofurantoin for Urinary Tract Infection "I went to the doctor for a complaint of a UTI. The doctor prescribed Macrobid for 5 days, twice a day. It definitely worked for the UTI within 2 days, but I had severe side effects: sharp abdominal pains, urine turned dark orange, no appetite, headaches, terrible nausea, left shoulder pain, back pain, tired, almost felt like my head was in the clouds. When I finished the medication, I felt worse. I felt like I wanted to cry. I felt confused, still no appetite, I didn’t feel like myself at all. Stomach cramping pains still with a distended abdomen. I literally almost felt like a walking zombie. I’m still getting abdominal cramps and a swollen abdomen. I need to see my doctor. I’m never taking this medication again."

Nitrofurantoin for Prevention of Bladder infection "Was put on Macrobid when my yearly physical lab showed a slightly higher WBC in urine. After 2 doses, I began with chills and fever. I had three days of 104 temp, nausea, and vomiting, even water would not stay down. As a senior adult living alone, I feared the need for IV and hospital treatment but would not go due to Covid. I called my doctor back and was told to go get tested for Covid. They offered no other reason for my ills. I did my own research and took myself off of the drug. 24 hours later, no chills, fever is normal, no vomiting. This was like poisoning my body. Never again! My daughters had similar experiences also. Be aware if taking this drug. I do not think it should be on the market."

For Bladder Infection "Prescribed for a very mild UTI, wish I never had, severe headache, stiff neck and shoulder muscles like cement, nausea, feels like brain is swooshing with movement, exhausted, emotional. Possibly the worst side effects I have ever had of any medication. Have never had any trouble with an antibiotic. I'm only 2 days in and 5 to go, I'm so tired, my hand is getting tired and strained for effort just to type this. Sounds all exaggerated, but I feel utterly terrible."

Nitrofurantoin for Urinary Tract Infection "After reading all the horror stories, I was dreading taking this, but I’m hoping my experience will help others out! I was diagnosed with a UTI. My OBGYN prescribed Bactrim, in which I had a horrible reaction and found out I had an allergy to, so she switched it to Macrobid. I was afraid to take it since everyone on here seems to complain, however, I read a successful post where one girl said she took it with a muffin, so that’s what I did. I ate a HEAVY meal, then waited about 30-45 minutes. I took a jumbo muffin and ate half of it, then took the pill, and then ate the remaining half of the muffin. No nausea, no diarrhea, no dizziness, nothing! Now keep in mind that all of our bodies are different, and so are our tolerances, but this is not as bad as it seems if you drink plenty of water and eat lots of food prior to taking it, including bread items! Best of luck!"

Nitrofurantoin for Urinary Tract Infection "Started Macrobid 5 days ago. I’ve taken Cipro before and it’s always worked well. My doc was on vacation, so I went to another clinic. She told me that they stay away from prescribing Cipro, so she suggested Macrobid and said it was well tolerated. First, I want to let you know that it did not work for me. I’m on day 5 & the burning right now is just as it was when my UTI started. When I started taking it, I felt nauseous, dizzy, balance issues, weak arms, depressed and weepy. This is out of character for me. I’ve hardly worked due to feeling incredibly weak and tired. I'm self employed and 4.5 of my days have been completely wiped out by this drug. I also have cramping in my feet and today I had bizarre facial flushing, hot ears and high blood pressure for 5 hours. I’ve always had normal blood pressure so this was scary. DO NOT TAKE THIS!"

For Prevention of Bladder infection "I honestly have had a great experience with this medication. I take one pill of Nitrofurantoin 100mg right after sex and also eat an apple with it. I used to not eat food while taking it or on an empty stomach and got so nauseous but would not throw up. I'm the type of person that gets a UTI/bladder/kidney infection every single time after sex. I tried every natural preventative measure I could and still got infections. This saved my sex life tremendously and it's made me so happy to be able to be intimate again. The reviews are scary, but it was definitely worth a shot and I'm so glad I took it!"

Nitrofurantoin for Urinary Tract Infection "Macrobid was the worst antibiotic I've ever taken. I have never had a UTI, and when I saw my doctor, she prescribed Macrobid 2x daily for 7 days. I have taken plenty of antibiotics in my lifetime and have never had any significant side effects. Within 4 hours of taking Macrobid, I had terrible diarrhea for about 2 hours. After that, I was nauseous to the point of vomiting (and I never vomit). No medication has ever made me this sick before. I had chills, weakness, diarrhea, and vomiting all within the first 12 hours. However, I know you're not supposed to stop taking medications, so I took my second dose, and the symptoms proceeded to the point of not sleeping at all overnight. I stopped taking it the next day, and my symptoms resolved completely. I went back to my doctor and got a different antibiotic that I had no problems with."

Nitrofurantoin for Urinary Tract Infection "Took Macrobid (Nitrofurantoin) twice for a UTI. The first time, I experienced a slight fever, chest pains, and difficulty breathing. I switched medication after speaking with my doctor, but I did not know that it also went by the name Macrobid as the generic brand. I had taken Macrobid before and was fine, so assumed that this was a one-off instance of bad side effects. Now taking it for a second time, and am experiencing very bad side effects of nausea, splitting headaches, slight fever, fatigue. No other UTI medicine I’ve taken before has caused similar reactions. Would not recommend taking something so risky when there are plenty of other just as effective alternatives."

Nitrofurantoin for Urinary Tract Infection "Was so traumatized to take this med based on other reviews. I'm 120 and 5'4 and get sick and nauseous from even one tylenol regular strength. I got Pedialyte to prepare... Took the pill and waited. And NOTHING happened except my UTI going away. Do yourself a favor and don't read the Internet. Trust your doctor!"

Nitrofurantoin for Bladder Infection "The first three days I took 100 mg of generic Macrobid twice a day with large meals because it was causing mild queasiness. UTI symptoms subsided. On the fourth day, I took it with a small breakfast and experienced dizziness and heart pressure. I called the doctor, who said that I had been on it long enough and advised me to stop. A decade or more ago, I took Cipro with no side effects for UTI, but now they say Macrobid is better due to antibiotic resistance and targeting UTIs specifically. The dizziness and heart pressure side effects were enough to make me stop and reconsider ever using this medicine in the future."

Nitrofurantoin for Urinary Tract Infection "I took the antibiotic for 5 days for a UTI. On the first day, it did cause a bit of nausea and dizziness, but nothing too drastic. For the rest of the days, I had no side effects at all. I always took it with a meal to prevent nausea or an upset stomach."

Nitrofurantoin for Bladder Infection "I had a pretty bad UTI, so I went to urgent care to get some relief. They prescribed this drug, Macrobid 100 mg x 2 for 5 days. I’m very sensitive to medications. Within 2 doses, my constant urge to pee was gone. By the 3rd dose, the burning was gone. I’m ending out my 4th day and 8th dose feeling completely better. The drug does cause some drowsiness, and I have been dizzy as well, which I got after my first dose. I’ve also had some diarrhea, but not too much. After my 8th dose tonight, I do feel a little bit queasy, but all antibiotics have some side effects. I’ll keep taking it. Cipro and Bactrim made me feel way worse."

Nitrofurantoin for Bladder Infection "The first few days after taking Macrobid, the symptoms weren’t too bad. I was experiencing a little stomach problems, diarrhea mainly. About day three on, I got really sick, really bad nausea and upper belly ache, pounding headaches, felt lightheaded. I couldn’t function, had to lay down and rest all of the time. I realized I was halfway through the dosage and thought I could tough it out, but had to stop at day six (7 day dosage). This is now day 7, and I haven’t taken any medication but still have strong symptoms, hopefully, will reside soon. I will never take this medication again, I felt like my body was being poisoned."

Nitrofurantoin for Bladder Infection "After being prescribed Monurol (a single dose, powder sachet antibiotic) for a pretty nasty bladder infection, I had to go back to the doctor because I was still in serious pain. My family doctor prescribed Macrobid, and after taking one dose, I started to have relief. I'm pretty sensitive to medications, I usually get the full list of side effects; headache, nausea, diarrhea, but with Macrobid, absolutely nothing - not even the weird possible 'darkening of urine'. Believe me, I'm a big baby, I'd whine about anything, this medication was amazing."

Nitrofurantoin for Prevention of Bladder infection "I have had recurring UTIs for 5 decades. I've been on Macrobid for a couple of years. I've found it does help prevent the kidney and bladder infections with few side effects. The side effects I do have are: darkened urine, diarrhea occasionally, nausea and dry heaves occasionally, dizziness occasionally, and peripheral neuropathy on occasion. Now, I know you would think that these side effects would deter someone from taking this drug, but for me, those side effects are better than having bladder and kidney infections for 6 months at a time. For me, Macrobid is the lesser of the two evils. Living with the infections is worse than these few issues."

Nitrofurantoin for Bladder Infection "Both extremes of Macrobid are accurate. I've had a lot of UTIs - to the point of having Macrobid prescribed with refills as needed. I never experienced any symptoms, and this stuff was like a miracle. It took 24 hours to kick in, and I felt great. I didn't get a UTI for 2 years and then just got one. I took Macrobid, and it has made me feel horrible! I feel weak, have no energy, am always dizzy, have headaches, diarrhea, bad pain around my lymph nodes, and always feel like I need to throw up. Fortunately, I'm a SAHM (stay-at-home mom), so I'm able to deal with it at home, but I had to have someone take my child to school because I couldn't get out of bed! Also, it feels like it hasn't completely started working. So it can be great and horrible, even with the same person!"

Nitrofurantoin for Bladder Infection "I am on day 2 of the medication nitrofurantoin for a bladder infection. Bactrim never works for my UTIs, Cipro makes me hallucinate, so the doctor prescribed Macrobid. All symptoms of UTI are gone. I do have some nausea, bloating, loose stool, even with probiotics, but all the side effects are so much better than having a UTI. I hope the rest of my treatment course stays like this. Bottom line, this medication has been effective and I would take it again for my UTIs."

Nitrofurantoin for Bladder Infection "I am on my seventh day on Macrobid and still having UTI symptoms. I have nausea, headache, abdominal cramping, irritability, loss of appetite, weakness, joint aches, and tiredness. This is the most ridiculous antibiotic that I've ever taken! It makes me feel like I've been hit by a bus and still doesn't seem like the UTI is better."

Nitrofurantoin for Urinary Tract Infection "It worked really well to clear up my urinary tract infection, and within a day I had no symptoms; however, I was so tired while I was taking this! I also would get a feeling of nausea quite often and occasionally would make me vomit. I took it on a full stomach, but still got the feelings of nausea and fatigue."

Nitrofurantoin for Urinary Tract Infection "Never again. I thought I was going to die. I was prescribed this drug for a UTI. 2 tabs a day for 3 days. 2 tablets in, I was in so much pain in every inch of my body I couldn't walk. I felt like I had a pain in my chest every time I needed to take a breath, and my headache was the worst I'd ever experienced. My vision was blurry, and I was constantly thirsty despite being hydrated. I felt queasy, and my skin was so sore to touch I couldn't even pull on my trousers. I know everybody is different, but after checking about other users' experiences, there is obviously a huge issue with side effects and this medication. I thought if I did manage to sleep, I'd never wake up again. I tried pain meds, but nothing touched this. I phoned my doctor and was told to stop taking them. My experience was so horrendous I'm frightened to take anything else again. I'm hoping that once it's out of my system, I'll feel better, but 4 days on, I still feel some effects."

Nitrofurantoin for Bladder Infection "Had a severe bladder infection, passing blood clots in my urine, pain, bladder spasms, and urinating every 5 minutes. I am allergic to sulfur drugs, penicillin, cipro, and levaquin, so Macrobid is really my only alternative. This is the second time I have taken it, the first time I remember no real side effects, this time I have experienced a severe headache after the first 3 pills, then that subsided. Now, on my 12th pill out of 14, I have mild nausea, dizziness, and drowsiness... nothing unbearable and definitely better than the pain of the bladder infection. Hopefully, I won't get another bladder infection, but that's wishful thinking, but I won't hesitate to use Macrobid again."

Nitrofurantoin for Bladder Infection "This is the second time I've used Macrobid, and I've concluded it does not work for me. With other antibiotics, I've gotten relief from UTIs within hours. Not with this stuff. I'm on day 3, and my symptoms keep returning, along with nausea and diarrhea. I can't wait to get some Bactrim."

For Urinary Tract Infection "Prescribed nitrofurantoin as a seven-day course for UTI. Was careful to take with food and expected maybe some nausea. OMG, what a horror story. I can't believe this drug is legal. Started with mild nausea and indigestion. Got worse with each dose and each day. Vomiting, diarrhea, head spinning, pounding headache. Felt so ill I thought I had COVID-19. Yes, it's dealt with the UTI, but I currently (end of day 4) feel like I'm dying. Am speaking to the pharmacist tomorrow, begging to be allowed to stop this awful medication."

Nitrofurantoin for Urinary Tract Infection "This medication made me feel horrible. I had a UTI and was prescribed this Macrobid. I took one dose. Within about 15-30 minutes, I felt so miserable. It worsened as the day went on. I felt anxious, dizzy, nauseous, my face tingled, and I couldn't concentrate. And the worst part was it was long-acting, so it took quite some time to feel normal. I will never take this again."
