Nitro Mono
Last thursday I went to the doctor & they told me I have a UTI. They put me on Nitrofurantoin 2 pills a day for 7 days. I am on my 6th day and I still have to urinate a lot and there is just some discomfort not as bad as before. It doesn't hurt at all when I urinate like it did. I heard this is a good prescription to be on when having a UTI, but I feel like I should be almost 100% better by now. Will this go away? ## Hello, Amanda! How are you? Yes, the general rule is that you should start to see improvement after 3 days, so by day 6, it should be mostly cleared up. There is a chance that it's just not the right antibiotic to treat your infection, or you may need a longer course of it. Has it cleared up? This medication may cause side effects, such as nausea, dizziness, non...

nitrofurantoin mono mcr 100 for staph infection related UTIs
My doctor told me that Cipro or Bactim are very good for treating UTIs caused by E-Coli, but that Nitrofurantoin Mono_MCR is better than the other two for treating UTIs caused by staph infection. Can you tell me any more about this. ## Hello, Ed! How are you? What else do you want to know about it? It is as simple as your doctor stated, different antibiotics are sometimes better at treating different things. It doesn't mean that the others can't be used, if necessary or if someone is allergic to the preferred choices, but it may take longer and be more difficult to eradicate the infection. They may all cause common side effects, such as nausea, dizziness, non-allergic skin rash and diarrhea.

Information on Nitrofurantoin Mono Mac 100MG CAPS
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...

nitrofurantoin mcr 100
My mother is taking Nitrofurantoin-mcr 100 for a UTI infection. In the past she has been on other antibiotics for the same and the infection has come back within days of use. Now she has been using the nitro- for 3 days, she has noticed that now it seems she has a bit of thickened blood in her urine. She is also taking a blood thinner(cumadin) for a heart problem. Is this a possible side effect of the med. ## Hello, Ken! How is your mother doing? On this, I'd suggest she see her doctor to have it checked out. It may just be from the UTI, but with her being on the Coumadin, any bleeding can be risky and isn't something to just wait around and see what happens. Do they know what's causing the repeated UTIs?

nitrofur macr 100 mg Is this for Prostate Infections?
My husband has a prostate infection and this antibiotic has been prescribed. He was on a different antibiotic for 2 weeks that was 500 mg. the doctor says that it is almost cleared but has prescribed nitrofur macr 100 mg for 2 more weeks. Will this clear it up all together? ## Hi, Gayle! How is your husband feeling? Nitrofurantoin is an effective antibiotic and if another was needed, then it's normal for the doctor to want to switch, instead of using the same one again. Doing so helps prevent the development of antibiotic resistant bacteria. He may experience side effects, such as nausea, dizziness, non-allergic skin rash and diarrhea. Learn more Nitrofurantoin details here. Are there any other questions or concerns? ## I have a prostate infection Bacteria DR prescribed Cipro 500 mg...

how long do side effects of nitrofurantoin mono mac last
I have a rash all over my body after a 10-day course of nitrofurantoin mono macro. The rash started the day after I finished the antibiotic. How long can I expect it to last as the itching is driving me crazy!! ## Hello, Sharon! How are you doing? If it's an itchy rash, then that's most likely from an allergic reaction, the rash that antibiotics can cause as a side effect is specifically called a non-allergic rash, because it just causes a topical skin rash, with no itching or hives. Learn more Nitrofurantoin details here. Have you consulted your doctor? An allergic rash may require proper medical treatment and you will most likely not be able to take this antibiotic again, in the future. ## I'm 28 yrs old and was prescribed macrobid 100mg for a bad bladder infection yesterd...

Nitrofur Macr 100 Mg/ how long does it take?
About how long does it normally take before you start feeling the effects? I am using it to treat a urinary tract infection. ## Hi Jane, It's hard to say how long it can take for you to "feel" the effects of a drug, as every drug can effect each individual differently. If you're curious about what the proper dosage should be for a UTI and how long you should be taking it for, then the information below will be very helpful in that regard: "The recommended nitrofurantoin dosage for treating UTIs in adults is 50 to 100 mg four times daily, continued for at least three days after the infection has cleared. For uncomplicated infections, the lower amount is usually recommended. For long-term treatment to prevent UTIs in adults, a dose of 50 or 100 mg once daily at bedtime...

Nitrofurantoin 25 mg/5ml oral susp
I was diagnosed with Trigonitis and my gyn has prescribed Nitrofurnantoin oral suspension ( cannot swallow pills) to be taken at bedtime for 5 weeks. I also have nodules in my lungs which from time to time my pulmonologist will order a chest x ray or cat scan. No significant changes but my pulmonologist will periodically order a chest x ray or cat scan. I do not have any breathing problems etc. Will this new medication be bad/cause complications for my lung issue? ## Nitrofurantoin is an antibiotic more commonly known for its use in treating urinary tract infections. No one can honestly know for sure how this medication will end up effecting you overtime, until you have tests done periodically. From what I've researched on my own, there are some potential adverse effects that can im...

is it ok to take nitrofurantoin mono mac 100 mgs with oncovite vitamins? oncovite contains calcium carbonate
There is calcium carbonate in the Oncovite ingredients and I am wondering about the interaction with Nitrofurantoin mono mac 100 mg ## Yes, the calcium can cause you to absorb less of the Nitrofurantoin. However, it says that this can be avoided if you take them at least 2 hours apart. Since the calcium coats you stomach, it prevents full absorption of the medication if they are taken at the same time. You should double check this with your doctor or pharmacist, but that is what is currently listed. Is there anything else I can help with?
