nitrofurantoin side effects while taking norco
2 Replies RSS
I am trying to find out if it is ok to take norco with nitrofurantoin mcr 100 mg. Are there any dangers of mixing the two? ## Hello, Alex! How are you? I didn't find any interactions or problems listed between the two, but it's always best to double check such information to be sure. But these are commonly prescribed together, to treat the possible pain an infection may cause, until the antibiotic can clear it up. The FDA classifies Norco as a narcotic analgesic, so it has the potential to be habit forming and may cause side effects, such as nausea, dizziness, drowsiness, dry mouth and constipation. Nitrofurantoin is an antibiotic and its typical side effects may possibly include nausea, dizziness, headache, non-allergic skin rash and diarrhea. Is there anything else I can help ...

Nitrofurantoin mono/Mac 100mg side effects
3 Replies RSS
After taking this medication for three days, I did not experience any side effects except for intense headaches right after taking it. On the fourth day I woke up with extreme shortness of breath, feeling of heaviness in my chest, chills, and joint pain. I have never had this sort of reaction to an antibiotic before, or any sort of medicine for that matter, so I thought I might have the flu. I went to the doctor and tested negative for the flu and he said I may have been suffering from really bad allergies. I forgot to take both of the antibiotic pills that day and woke up the next morning feeling better. I then took two pills, one in the afternoon and one at night, and woke up the next day the same as the fourth day. Are these normal side effects for this antibiotic? Also, what about t...

Can the prescription Nitrofurantoin be taken for the sympthoms of earache, sore throat, headache, and skin sore to the touch? I was also chilling twelve hours ago. ## Nitrofurantoin is used to treat urinary tract infections. Nitrofurantoin is in a class of medications called antibiotics. It works by killing bacteria that cause infection. Antibiotics will not work for colds, flu, or other viral infections. That said, I think it would be best to diagnose the underlying causes of your sore skin, headache, sore throat, and ear ache. In my honest opinion, a naturopathic doctor would best suit your needs for all the above symptoms and conditions. Additionally, I do see some antibiotics being prescribed for ear aches; however Nitrofurantoin is primarily used for UTI's, so you may also want...

Looking for an alternative drug to Nitrofurantoin
3 Replies RSS
I've been taking low dose 50mg Nitrofurantoin for over a year. My urologist recommended it and my PCP also said I should take it for life. I've had frequent UTI's/year and it's been a problem for more than 10 years. I've been free of UTI's since I went on the low-dose Nitrofurantoin. It's helped me greatly but I've developed some respiratory problems and my Dr. thinks that my long term use of this drug might be the cause of my problems. I would like to find an alternative antibiotic to Nitrofurantoin. Any clue what drug would be equivalent? ## Hello, Tipsy! How are you? I'm sorry about the problem that you're having. According to the information provided by the NIH, the other antibiotics that can be used for prophylaxis of UTIs include Bactrim, Tr...

side effects of nitrofurantion
Post a Reply
My Dr said I had a UTI, all though I had no symptoms, so put me on a course of nitrofurantion. I started feeling faint, about to pass out, my heart was racing, and I was breathless, I returned to the Dr, and he put me on a higher dose, I felt even worse, and my right eye couldn't focus properly, I ended up in hospital for a week, still having funny turns, but they couldn't find anything wrong with me. And denied it could be the nitrofurantion. My optician checked my eyes ,and said vision in one eye had got worse,I went back after three weeks, and it had gone back to normal,he said it could have been the pills. This was last September, but I still feel absolutely exhausted, and all my muscles feel weak, could it have such a lasting effect.

Yes I was released from the hospital with a severe UTI infection and Nitrofurantoin Mono/Mac
1 Reply RSS
Upon being release, not only did/do I have this severe, I believe the Dr, called it, UTI infection, but I have 2 other infections, dehydration, sinunitus, pneaumonia, and infected ears. I do have a variety of medications for each ailment, however, the only one I take more than once a day is the Nitro.Mac/Mono. I am so itchy my skin looks horrible and I cannot find any type of relief. I've NEVER itched like this unless I had poison ivy and now the calamine isnt even phasing this. How likely is it the Nitro.mac/mono responsible for this horribleness that I cant get away from this exhausting itch, havent slept a wink for scratching. Please help me. . . ## Hello, Kim! How are you? I'm very sorry about the problem that you're having. There is a chance that it is due to the Nitrof...

Should I feel better after taking 3days of nitrofurantoin mono Mac? ## Hello, Denise! How are you? Yes, the general rule with antibiotics is that if if they are working, there should be no worsening of the infection after a full 24 hours of taking them and you should see improvement after 3 full days of taking it. The FDA lists the typical side effects as possibly including nausea, dizziness, headache, non-alelrgic skin rash and diarrhea. If you're not seeing any improvement, you should return to your doctor, you may need to try a different antibiotic. Is there anything else I can help with?
