Nitrofur Macr 100 Mg/ how long does it take?
18 Replies RSS
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...

I am 82 and had UTI from the 1st of April. By 16th April , not better, I needed to start on my third lot of Nitrofurantoin. That day I became very ill. My symptoms lasted three days and nights. Every joint was aching. My arm was as sore as if I had bumped it. I hadn't. It hurt to turn my eyes. I had trigeminal pains and my head was aching. I was being sick although I had an empty stomach.the frightening thing was I was shuddering so violently. my arms were jerking uncontrollably. I have never felt so weak and exhausted. The day I stopped taking the medication was the day those symptoms subsided leaving me totally exhausted and weak. How long will it take to get over this. I am taking my last doses of Pivmecillinam today and can tell that the Cystitis has gone , but I am so short of ...

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...

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...
