Metronidazole
Arilin Rapid is a medicine in the form of vaginal capsules containing metronidazole, a chemotherapeutic agent from the nitroimidazole group. In susceptible anaerobic bacteria, as well as in some protozoa, metronidazole inhibits the synthesis of nucleic acids, leading to the death of microorganisms. No cross-resistance to metronidazole has been observed in microorganisms resistant to antibiotics. Arilin Rapid is indicated for the treatment of trichomoniasis or non-specific bacterial vaginitis.
Before starting treatment with Arilin Rapid, you should discuss it with your doctor or pharmacist, especially if you have:
If the patient experiences any of the following symptoms during treatment with Arilin Rapid, they should immediately seek medical help and stop taking the medicine. See also section 4.
Until the doctor arrives, the patient should be placed in a horizontal position, with their legs raised, covered with a blanket to prevent a drop in body temperature. The doctor will administer appropriate emergency measures (e.g., administer antihistamines, corticosteroids, sympathomimetic agents, and, if necessary, provide respiratory support).
During treatment with metronidazole, cases of severe hepatotoxicity (acute liver failure), including fatal cases, have been reported in patients with Cockayne syndrome. In patients with Cockayne syndrome, the doctor should monitor liver function during and after treatment with metronidazole. You should immediately inform your doctor and stop taking metronidazole if you experience any of the following symptoms: abdominal pain, loss of appetite, nausea, vomiting, fever, malaise, fatigue, jaundice, dark urine, clay-colored or loose stools, or skin itching.
Metronidazole should not be used for more than 10 days, except in special situations. Treatment may be repeated very rarely, as it cannot be excluded that it may cause damage to human primary sex cells. Additionally, in animal studies, the development of various tumors has been observed. Arilin Rapid may damage latex products (e.g., condoms, vaginal caps), thereby reducing their effectiveness.
You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take. The following interactions have been observed after systemic administration of metronidazole (oral, rectal, or intravenous).
Anticoagulant medicines from the coumarin group (e.g., warfarin, acenocoumarol). The doctor should closely monitor coagulation parameters, as metronidazole increases blood coagulability and may require an increase in the dose of the anticoagulant medicine taken.
Lithium. When used concomitantly with metronidazole, an increase in lithium serum concentration has been observed.
Barbiturates and phenytoin reduce the effectiveness of metronidazole.
Cimetidine may, in individual cases, affect the elimination of metronidazole from the body, thereby increasing its serum concentration.
After administration of silymarin/silibinin (active substances used in the treatment of liver poisoning), a decrease in the effectiveness of Arilin Rapid has been observed.
Medicines containing diosmin (an active substance used in the treatment of venous diseases) may increase the concentration of metronidazole in the blood, thereby enhancing its effect and/or side effects.
When metronidazole and cyclosporine (a medicine that suppresses or weakens the immune response) are administered concomitantly, the cyclosporine serum concentration may be increased. Therefore, cyclosporine and creatinine serum levels should be closely monitored.
The toxic effect of 5-fluorouracil (a chemotherapeutic agent used in the treatment of tumors) is increased, as its elimination is reduced when administered concomitantly with Arilin Rapid.
The toxic effect of busulfan (a chemotherapeutic agent) may be significantly enhanced.
Effect on the results of some laboratory tests. Metronidazole may decrease the results of aspartate aminotransferase (AST) measurements in serum.
Concomitant administration of metronidazole and tacrolimus (a medicine that prevents transplant rejection) leads to an increase in tacrolimus blood concentration. Therefore, tacrolimus blood concentration and kidney function should be frequently monitored.
Concomitant use of metronidazole and amiodarone (a medicine used in the treatment of heart rhythm disorders) may affect heart function. Therefore, heart function should be regularly monitored by performing an ECG. You should consult your doctor if you experience symptoms of heart rhythm disorders, such as dizziness, palpitations, or short-term fainting.
When metronidazole is administered concomitantly with antibiotics, the availability of mycophenolate mofetil (a medicine that suppresses the immune system) in the body may be reduced. Therefore, it is recommended to monitor this concomitantly through laboratory tests.
Alcohol consumed during metronidazole treatment may increase the risk of side effects, such as flushing of the skin and neck, nausea, vomiting, headaches, and dizziness (similar to disulfiram). You should not drink alcohol during and within 48 hours after the end of Arilin Rapid treatment, as metronidazole may cause symptoms of alcohol intolerance after vaginal administration.
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult your doctor or pharmacist before using this medicine. Arilin Rapid should not be used during the first trimester of pregnancy (if you could be pregnant, you should have a pregnancy test before starting treatment). In the second and third trimesters of pregnancy, Arilin Rapid can be used only if, in the doctor's opinion, it is necessary, and other treatment methods are ineffective or contraindicated. During breastfeeding, you should not use Arilin Rapid. If its use is necessary, you should stop breastfeeding. If you have taken a single dose of the medicine, you should stop breastfeeding for 24 hours and discard the expressed milk during this time.
Arilin Rapid may affect your reaction speed and, therefore, your ability to drive and operate machines. The greatest impact may occur at the beginning of treatment and when you consume alcohol concomitantly. Consuming alcohol during metronidazole treatment may increase the risk of side effects, such as flushing of the skin and neck, nausea, vomiting, headaches, and dizziness.
This medicine should always be used as directed by your doctor. If you have any doubts, you should consult your doctor or pharmacist. In primary infections, a single capsule (i.e., 1000 mg of metronidazole) is sufficient. In severe and recurrent infections, a two-day treatment (one capsule per day for two days) is recommended. The capsules should be inserted deep into the vagina, preferably in the evening, while lying on your back with your legs slightly bent.
After oral administration of a dose of up to 15 g of metronidazole, nausea, vomiting, hyperreflexia (increased reflexes), ataxia (impaired coordination), tachycardia (rapid heart rate), shortness of breath, and confusion have been observed. No deaths have been reported. There is no specific antidote. Complete disappearance of symptoms has been observed after a few days of symptomatic treatment. If you have taken a higher dose of the medicine than recommended, you should consult your doctor.
Like all medicines, Arilin Rapid can cause side effects, although not everybody gets them. After vaginal administration, only 20% of metronidazole is absorbed into the bloodstream; therefore, side effects during treatment with Arilin Rapid are rare. The following side effects have been observed during systemic administration of metronidazole (oral, rectal, or intravenous).
Infrequent(occurred in 1 to 10 out of 1000 patients):
Very rare(occurred in less than 1 out of 10,000 patients):
Frequency not known(cannot be estimated from the available data):
