I'm a 45 years old female. I diagnosed with UTI since 2013. I keep a helpful eating habits and do lifestyle changes, but I don't know why it recurs repeatedly.

Macrodantin Itchy Side Effect
4 Replies RSS
I was prescribed Macrodantin to treat my UTI. Twice daily for five days. About two days after I competed the antibiotics, I started to itch everywhere, especially my hands and feet. They feel like the after effects of mosquito or ant bites. It's been four days and I'm still itching. The more I scratch, the more swollen it gets. 50mg of Benadryl helps me sleep through the night but I wake up with the effects the next morning. Aloe Vera helps for a few minutes. What do I do? ## Hello, Cindy! How are you doing? Has there been any change? You might be allergic to this medication, and if that is the case, such allergic reactions tend to get worse with repeated exposure, according to the NIH, so it would be best to have this checked out by your doctor to be sure. If it is an allergic ...

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...

Hi I just started this medicine today for a UTI. Only took it twice. I feel nausea, my whole body aches like crazy like I have the flu. I'm running a fever, got chills, my stomach is cramping. I just wanted to know does anyone know how long the symptoms last? I'm sitting here crying it's that bad but can't call my doctor because it's the weekend.

can i give my dog this nitrofurantoin 100 mg
1 Reply RSS
My dog is a chawaa and I was wanting to know if I can give her nitrofurantoin mono-mcr 100 mg and if so how much ## Hello, Kimmy? How is your pup doing? Did you mean she's a chihuahua? If so, I would suggest not giving it to her, unless your veterinarian tells you to do so. Chihuahuas are usually tiny and can be very sensitive to medications, thus their dosage needs to be precisely calculated to avoid causing them harm. As reported by the Merck Veterinary Manual, an overdose could result in liver failure, kidney failure, and respiratory distress, any of which has the potential to be fatal.

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...
