Depending on the organism involved, cephalexin for a UTI may be very effective. There is a broad range of organisms which may cause a urinary tract infection (UTI) and the choice of treatment will be made according to this. To determine the organism involved, a urine sample will be sent to the lab for culture and sensitivity testing. Cephalexin is available in most countries by prescription only and may be known by different trade names, according to manufacturer.
Urinary tract infections are seen commonly, especially in women, and may present with discomfort or burning on urination, frequency of urination, abdominal pain and fever. They may occur in the lower urinary tract and be uncomplicated or in the upper urinary tract or be complicated. Medical attention should be sought urgently if a UTI is suspected to ensure the correct treatment is obtained and to prevent the infection from getting worse.
There are a number of different organisms which may cause a UTI and the choice of antibiotic will depend on this. In some cases a broad-spectrum antibiotic will be prescribed, without the need for testing for an organism but, in other cases, sensitivity testing will be done on the urine and the choice of antibiotic will be decided accordingly. Resistance to some antibiotics has developed in some UTI-causing organisms.
When using cephalexin for a UTI, it is usually given orally, either as a tablet, capsule or syrup. The dose is typically between one and two grams per day, divided into four doses throughout the day, but this may increase in the case of severe infections. It is important to stick to the prescribed dose and dosage regimen and to complete the full course of cephalexin, even if symptoms have resolved. Stopping a course of antibiotics before it is finished may result in resistance and difficulty treating should the infection recur.
As with any medication, side effects may occur when using cephalexin for a UTI. These may include gastrointestinal effects such as diarrhea, nausea and vomiting, headache and dizziness. Any negative side effects should be discussed with the doctor or pharmacist.
Interactions with other medications may occur when using cephalexin. Any other medications, including over-the-counter, homeopathic and complementary medications should be discussed with the prescribing doctor, as should any underlying clinical conditions. Cephalexin for a UTI may be very effective if the causative organism is sensitive to the antibiotic.
