Generally, the most commonly used drugs to treat a urinary tract infection, also called UTI are antibiotics, which should always be prescribed by the doctor, such as doxycycline, fosfomycin, cephalexin and rocephin, ciprofloxacin or levofloxacin.
In addition, antibiotics can be used with other medicines that accelerate healing and help to relieve symptoms, such as antiseptics, painkillers, antispasmodics and some herbal remedies.
Urinary tract infection is a problem that causes symptoms such as pain and burning sensation when urinating, urinary urgency and unpleasant odor, and is usually caused by bacteria from the gut that enter the urinary system. This is a more common disease in women, especially due to the proximity between the urethra and the anus. Find out if you have a urinary tract infection by doing our online symptom test.

- Nitrofurantoin (Macrodantin), whose recommended dosage is 1 pill of 100 mg every 6 hours for 7 to 10 days;
- Fosfomycin (Monuril), whose dosage is 1 sachet of 3 g in a single dose or every 24 hours for 2 days, which should be taken, preferably with the stomach and bladder empty, preferably at night, before bedtime;
- Sulfamethoxazole + trimethoprim (Bactrim or Bactrim F), whose recommended dosage is 1 pill of Bactrim F or 2 tablets of Bactrim, every 12 hours, at least 5 days or until symptoms disappear;
- Fluoroquinolones, such as ciprofloxacin or levofloxacin, whose dosage depends on the quinolone that the doctor prescribes;
- Penicillin or derivatives, such as cephalosporins, such as cephalexin or ceftriaxone, whose dosage also varies according to the prescribed medication.
If it is a severe urinary tract infection, treatment may be necessary at the hospital, with antibiotics given to the vein.
Generally, symptoms of urinary tract infection disappear within a few days of treatment. However, it is important that the person take the antibiotic during the time that has been determined by the doctor.
2. Antispasmodics and painkillers
Generally, urinary tract infection causes unpleasant symptoms such as pain and burning while urinating, frequent urge to urinate, abdominal pain or feeling of heaviness in the belly, so your doctor may prescribe antispasmodics such as flavoxate (Urispas), scopolamine (Donnatal and Phenohytro) and hyoscyamine (Tropinal), which are medicines that relieve all these symptoms associated with the urinary tract.
In addition, although it has no antispasmodic action, phenazopyridine (Urovit or Pyridium) also alleviates the pain and burning characteristic of urinary tract infections, since it is a painkiller that works in the urinary tract.
Antiseptics such as methenamine and methylthioninium chloride (Urogesic Blue) may also help relieve pain and burning while urinating, help eliminate urinary tract bacteria, and prevent recurrent infections.
There is also a great variety of supplements that have in their composition red cranberry extract, known as cranberry, that can be associated with other components that act to prevent the adhesion of the bacteria to the urinary tract and promoting the reconstitution of a balanced intestinal microflora, creating a environment to the development of urinary tract infections, and is therefore very useful as a complement to treatment or to prevent relapses.
Uro-Vaxom is a vaccine for UTI made up of components extracted from Escherichia coli, which works by stimulating the body's natural defenses and is used to prevent recurrent urinary tract infections or as an adjunct to the treatment of acute infections of the urinary tract.
Homemade remedies for UTI
One home remedy to alleviate the symptoms of urinary tract infection is to take a cranberry juice, grapefruit syrup or a stick of gold tea, for example. Learn how to prepare these natural remedies.
In addition, diuretic foods such as onion, parsley, watermelon, asparagus, graviola, cucumber, orange or carrot, are also a great complement to the treatment of infection, as they help to eliminate urine, contributing to the elimination of bacteria.
Remedies for special situations
If UTI occurs in children or pregnant women, the medication and dosages may be different.
Child urinary tract infection
In children, treatment is often done using the same type of antibiotics, but in the form of syrup. Therefore, the treatment should always be indicated by the pediatrician, and the recommended dose varies according to the child's age, weight, symptoms presented, severity of the infection and microorganism responsible for causing the infection.
Urinary tract infection during pregnancy
Remedies for urinary tract infection in pregnancy should be prescribed by the obstetrician and should be used with great caution so as not to harm the baby. The antibiotics for urinary tract infection that are considered safer to take during pregnancy are cephalosporins and ampicillin.
How to prevent recurring urinary tract infections
There are women who suffer from urinary infections several times a year and in these cases the doctor may recommend a preventive treatment to avoid relapses by daily intake of a low dose of antibiotics such as Bactrim, Macrodantine or fluoroquinolones for about 6 months or taking a single dose of antibiotic after intimate contact if the infections are related to sexual activity.
In addition, to avoiding recurring urinary infections, the person can also take natural remedies for a long period of time or immunotherapies.
In addition to the natural remedies and options, during treatment for urinary tract infection, it is recommended not to take any other medication without the doctor's knowledge and to drink about 1.5 to 2 liters of water a day, which helps to eliminate the bacteria from the body.
