1. What is neoFuragina and what is it used for
neoFuragina is available in the form of oral tablets. It contains furazidin as the active substance, also known as furagin. Furazidin is a nitrofuran derivative that inhibits the growth of bacteria that cause urinary tract infections.
- The indication for using neoFuragina is the treatment of lower urinary tract infections.
2. Important information before taking neoFuragina
When not to take neoFuragina:
- if the patient is allergic to furazidin, nitrofuran derivatives, or any of the other ingredients of this medicine (listed in section 6)
- if the patient has polyneuropathy (a condition characterized by damage to the peripheral nerves, which can cause motor, sensory, or other neurological disorders), e.g., in diabetic patients
- if the patient has a deficiency of the enzyme glucose-6-phosphate dehydrogenase (a genetic disorder that affects the metabolism of red blood cells)
- if the patient has renal failure (creatinine clearance below 60 ml/min or elevated serum creatinine levels)
- in newborns, infants, children, and adolescents
- during the first three months of pregnancy (first trimester)
- during the last month of pregnancy (from the 38th week) and during childbirth, due to the risk of hemolytic anemia in the newborn.
Warnings and precautions
If the patient has any of the following conditions (see also section 4), they should discuss the use of neoFuragina with their doctor.
- If the patient has diabetes, renal impairment, liver dysfunction, neurological disorders, electrolyte disturbances, anemia, vitamin B deficiency, or lung disease, they should be particularly cautious when taking this medicine, as the risk of peripheral polyneuropathy is increased. This condition can be irreversible and life-threatening in severe cases. Therefore, neoFuragina should be discontinued if neurological symptoms occur (tingling, numbness, sensation of electric currents).
- If the patient experiences fever, chills, cough, chest pain, or shortness of breath, these may be symptoms of acute pulmonary reactions, which can occur in patients treated with nitrofuran derivatives. If such symptoms occur, the medicine should be discontinued immediately. Chronic reactions can occur in patients taking furazidin for more than 6 months. Chronic pulmonary reactions can occur, especially in elderly patients.
- If the medicine is used for a long time, blood tests may be necessary to monitor white blood cell count and renal and liver function.
- Alcohol should be avoided during treatment with furazidin (see separate section below).
Rarely, liver function disorders (jaundice, itching, pale stools, dark urine, abdominal pain, vomiting, nausea, loss of appetite, constant fatigue, and weight loss) may occur, including cholestatic jaundice (caused by an obstruction of bile flow) and chronic hepatitis. If liver function disorders are detected, treatment with furazidin should be discontinued immediately.
Children and adolescents
neoFuragina should not be used in children and adolescents (see "When not to take neoFuragina" in section 2).
neoFuragina and other medicines
The patient should inform their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
- streptomycin, chloramphenicol, sulfonamides (antibacterial chemotherapeutics) - increase the toxic effect of furazidin on the hematopoietic system;
- quinolone derivatives, e.g., nalidixic acid, norfloxacin, oxolinic acid (antibacterial medicines) - furazidin may inhibit their antibacterial effect;
- probenecid and sulfinpyrazone (medicines that increase the excretion of uric acid in the urine) - may decrease the excretion of furazidin and cause its accumulation in the body, increasing its toxicity and reducing its concentration in the urine, which may lead to a decrease in its effectiveness;
- carbonic anhydrase inhibitors (sulfonamides) and medicines that increase the pH of urine (alkalizing) - may reduce the antibacterial activity of nitrofurans;
- vitamin B - increases the absorption of nitrofuran derivatives;
- atropine (a medicine that relaxes smooth muscles and dilates pupils) - may delay the absorption of furazidin, but the overall amount of absorbed substance does not change;
- antacids containing magnesium trisilicate reduce the absorption of furazidin - may decrease the antibacterial effect of furazidin.
The effect on laboratory tests: During the administration of furazidin, the results of glucose tests in urine using Benedict's and Fehling's solutions may be falsely positive. The results of glucose tests in urine performed using enzymatic methods are usually correct.
neoFuragina with food or alcohol
See section 3.
Alcohol should be avoided during treatment with neoFuragina due to the possibility of a disulfiram-like effect with symptoms such as a feeling of heat, abdominal pain, nausea, vomiting, and tachycardia.
Pregnancy, breastfeeding, and fertility
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
Pregnancy: neoFuragina should not be used during the first three months of pregnancy (first trimester) or in women with a advanced pregnancy (from the 38th week) and during childbirth.
Caution should be exercised when using neoFuragina during the last three months of pregnancy (third trimester), as furazidin may cause hemolytic anemia in the newborn.
Breastfeeding: neoFuragina should not be used during breastfeeding. Furazidin passes into breast milk and may harm the breastfed child.
Fertility: Nitrofuran derivatives may have a negative effect on testicular function, slightly or moderately reducing the total number of sperm in the semen.
Driving and using machines
There is no data on the effect of furazidin on the ability to drive vehicles and operate machines. However, some patients may experience side effects that can affect the ability to drive vehicles and operate machines (headache, dizziness, drowsiness, vision disturbances; see also section 4).
neoFuragina contains lactose monohydrate and sucrose
If the patient has previously been diagnosed with intolerance to some sugars, they should consult their doctor before taking the medicine.
3. How to take neoFuragina
This medicine should always be taken exactly as described in the patient leaflet or as advised by a doctor or pharmacist. If in doubt, the patient should consult their doctor or pharmacist.
Adult administration
Day 1: 1 tablet (100 mg) 4 times a day.
Day 2-8: 1 tablet (100 mg) 3 times a day.
Treatment usually lasts 7-8 days. If necessary, treatment can be repeated after 10-15 days.
Method of administration: The medicine is taken orally. The line on the tablet is only to facilitate breaking the tablet, not to divide it into equal doses.
neoFuragina should be taken during meals. The patient should follow a high-protein diet and drink plenty of fluids.
If the patient misses one or more doses, they should continue treatment with the previously taken doses.
Administration in children and adolescents
neoFuragina should not be used in children and adolescents (see "When not to take neoFuragina" in section 2).
Taking a higher dose of neoFuragina than recommended
If the patient takes a higher dose of the medicine than recommended, they may experience nausea, vomiting, headache, dizziness, allergic reactions, or anemia. If any worrying symptoms occur, the patient should immediately consult their doctor, pharmacist, or the emergency department of the nearest hospital, as specialized treatment may be necessary. Gastric lavage and administration of large amounts of fluids are recommended to increase the excretion of the medicine in the urine. Blood morphology tests, liver function tests, and monitoring of lung function are also recommended. In severe cases, hemodialysis may be necessary.
Due to the excretion of the medicine by the kidneys, the risk of overdose is increased in patients with renal impairment.
Missing a dose of neoFuragina
If the patient misses one or more doses, they should continue treatment with the previously taken doses. They should not take a double dose to make up for the missed dose.
Stopping treatment with neoFuragina
Stopping treatment with neoFuragina during the course of treatment may result in the infection not being fully cured.
If the patient has any further doubts about the use of this medicine, they should consult their doctor or pharmacist.
