1. What is Arilin rapid and what is it used for

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, after its administration, there is an inhibition of nucleic acid synthesis, and thus the death of microorganisms. It has not been found that microorganisms resistant to antibiotics are also resistant to metronidazole (there is no cross-resistance). Arilin rapid is indicated for use in trichomoniasis or non-specific bacterial vaginitis.

2. Important information before using Arilin rapid

When not to use Arilin rapid:

• if the patient is allergic to metronidazole, other 5-nitroimidazole derivatives, soy, peanuts, or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Before starting to use Arilin rapid, you should discuss it with your doctor or pharmacist, especially if the patient has:

• severe liver failure,
• blood formation disorders,
• diseases of the central or peripheral nervous system. The doctor will then carefully weigh the risk of using the medicine against the potential benefits.

If the patient experiences any of the following symptoms during the use of Arilin rapid, they should immediately seek medical help and stop taking the medicine. See also section 4.

• Sudden drop in blood pressure, shortness of breath, dizziness, and vomiting, disturbances of consciousness, cold sweats, and paleness and coolness of the hands and feet. These may be symptoms of a life-threatening anaphylactic shock. Until the doctor arrives, the patient should be laid down 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 drugs, and, if necessary, provide respiratory support).

Severe, prolonged diarrhea, occurring during and within a few weeks after the end of treatment. This may be a symptom of pseudomembranous colitis (a severe intestinal disease, usually caused by Clostridium difficile bacteria). This disease, associated with the use of antibiotics, can be life-threatening and requires immediate medical attention. The doctor will consider the use of appropriate treatment (e.g., prescribe specific antibiotics or chemotherapeutic agents). You should not take drugs that suppress intestinal motility (peristalsis).

• Fever, exhaustion, inflammation of the tonsils and oral cavity. These may be symptoms of agranulocytosis. After the appearance of the above symptoms, you should contact your doctor as soon as possible, who will prescribe a blood morphology test.
• Feeling of numbness, disturbances of sensation, and tingling in the limbs. These may be symptoms of peripheral neuropathy. Immediate medical attention is necessary.

During the use of metronidazole in patients with Cockayne syndrome, cases of severe hepatotoxicity (acute liver failure), including cases resulting in death, have been reported. 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 ruled out that it may damage human primary sex cells. Additionally, in animal studies, the development of various tumor changes has been observed. Arilin rapid may cause damage to latex products (e.g., condoms, vaginal caps), and thus reduce their effectiveness.

Arilin rapid and other medicines

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 carefully monitor coagulation parameters, as metronidazole increases blood coagulability and may require an increase in the dose of the anticoagulant medicine being taken. Lithium. During concurrent use 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, resulting in an increased metronidazole 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 vein diseases) may increase the metronidazole concentration in the blood, and consequently, enhance the effect and/or side effects of Arilin rapid. When cyclosporine (a medicine that suppresses or weakens the immune response) and Arilin rapid are administered concurrently, the cyclosporine serum concentration may be elevated. Therefore, cyclosporine and creatinine serum values should be closely monitored. The toxic effect of 5-fluorouracil (a chemotherapeutic agent used in the treatment of tumors) is increased, as the concurrent administration with Arilin rapid reduces the excretion of 5-fluorouracil. The toxic effect of busulfan (a chemotherapeutic agent) may be significantly enhanced. Effect on the results of some laboratory tests. Metronidazole may reduce the results of aspartate aminotransferase (AST) activity measurements in serum. Concurrent administration of metronidazole with 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. Concurrent 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 observe symptoms of heart rhythm disorders, such as dizziness, palpitations, or short-term fainting. When metronidazole is administered concurrently 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 concurrently through laboratory tests.

Arilin rapid and alcohol

Alcohol consumed during the use of metronidazole may increase the risk of side effects, such as flushing of the skin and neck, nausea, vomiting, headaches, and dizziness (an effect similar to disulfiram). You should not drink alcohol during and within 48 hours after the end of Arilin rapid treatment, as after vaginal administration of metronidazole, symptoms of alcohol intolerance may occur.

Pregnancy and breastfeeding

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. You should not use Arilin rapid 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.

Driving and using machines

Arilin rapid may affect your reaction speed and, consequently, your ability to drive vehicles and operate machines. The greatest impact may occur at the beginning of treatment and when you concurrently consume alcohol. Consuming alcohol during the use of metronidazole may increase the risk of side effects, such as flushing of the skin and neck, nausea, vomiting, headaches, and dizziness.

3. How to use Arilin rapid

This medicine should always be used in accordance with the doctor's recommendations. In case of doubts, you should consult your doctor or pharmacist. In primary infections, the administration of one capsule (i.e., 1000 mg of metronidazole) is sufficient. In severe and recurrent infections, a two-day treatment (one capsule for two days) is recommended. The capsules should be inserted deep into the vagina, preferably in the evening, lying on your back with your legs slightly bent.

Use of a higher than recommended dose of Arilin rapid

After oral administration of a dose of up to 15 g of metronidazole, nausea, vomiting, hyperreflexia (increased reflexes), ataxia (lack of 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. In case of taking a higher than recommended dose of the medicine, you should consult your doctor.

4. Possible side effects

Like all medicines, Arilin rapid can cause side effects, although not everybody gets them. After vaginal administration, only 20% of metronidazole penetrates 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).

• Frequent(occurred in 1 to 10 out of 100 patients):
• metallic taste in the mouth, bitter taste when belching, coating on the tongue, inflammation of the tongue, inflammation of the oral mucosa, pressure in the stomach, nausea, vomiting, loss of appetite, diarrhea.
• darkening of urine (caused by a metronidazole metabolite). This change has no clinical significance.

• liver function disorders (increased aminotransferase activity and bilirubin concentration in the blood);
• fungal infections (Candida) in the genital area;
• muscle weakness, vision disturbances.

Very rare(occurred in less than 1 out of 10,000 patients):

• anaphylactic shock (sudden drop in blood pressure due to hypersensitivity); in severe cases, shortness of breath, dizziness, and vomiting, disturbances of consciousness, cold sweats, and paleness and coolness of the hands and feet may occur; see section 2, Warnings and precautions;
• thrombocytopenia (reduced platelet count);
• agranulocytosis (lack of a specific type of white blood cells);
• pancreatitis;
• pseudomembranous colitis (a severe intestinal disease, characterized by persistent diarrhea); see section 2, Warnings and precautions;
• allergic reactions caused by 3-sn-phosphatidylcholine (from soybeans) - a component of the lecithin contained in the capsules;
• joint pain.

Frequency not known(cannot be estimated from the available data):

• atypical brain changes, cerebellar syndrome [e.g., speech impairment, gait disturbances, involuntary eye movements (nystagmus), and seizures];
• severe skin reactions with life-threatening general reactions (e.g., erythema multiforme; toxic epidermal necrolysis (Lyell's syndrome));
• hepatitis, sometimes with jaundice. In patients treated concurrently with other antibiotics, cases of liver failure requiring liver transplantation have been reported.
• acute liver failure in patients with Cockayne syndrome (see section 2, Warnings and precautions).
