Rimantadine-STI 50 mg, 20 tablets

What is Rimantadine-STI 50 mg?

Rimantadine-STI is an antiviral medication used to prevent and treat influenza A in adults and children over the age of 7.

It works by inhibiting the replication of the influenza A virus, thereby reducing the severity of the infection and helping to prevent the spread of the virus.

Each tablet contains 50 mg of the active ingredient rimantadine hydrochloride, and the medication is typically used for both early treatment and prevention of flu outbreaks.

How is Rimantadine-STI used for flu prevention and treatment?

Rimantadine-STI is most effective when taken within the first 24-48 hours of flu symptoms. For adults, the recommended dosage is as follows:

• Day 1: 100 mg three times daily
• Days 2-3: 100 mg twice daily
• Days 4-5: 100 mg once daily

Children between the ages of 7 and 10 should take 50 mg twice daily, while those aged 11 to 14 should take 50 mg three times daily. For flu prevention, adults can take 50 mg once daily for up to 30 days, while children over 7 years can take the same dose for up to 15 days.

Who should avoid taking Rimantadine-STI?

Rimantadine-STI is not suitable for everyone. It should be avoided by individuals who are allergic to rimantadine or any of its ingredients, including people with a known sensitivity to adamantane-class medications. It is also contraindicated in people with severe liver or kidney conditions, thyroid disorders such as thyrotoxicosis, and those with lactose intolerance, as the tablets contain lactose. Pregnant and breastfeeding women should not use this medication, and it is not recommended for children under 7 years of age.

What precautions should be taken while using Rimantadine-STI?

If you have certain health conditions such as high blood pressure, epilepsy, or atherosclerosis, use Rimantadine-STI with caution. In such cases, your doctor may adjust the dosage to minimize the risk of side effects. If you experience any serious side effects such as seizures, the medication should be stopped immediately.

It is important to note that Rimantadine does not prevent complications from the flu, such as bacterial infections, which may coexist with or arise as a result of the flu.

What interactions should I be aware of?

Rimantadine-STI may interact with other medications, reducing their effectiveness. For instance, it can lower the efficacy of antiepileptic drugs, while drugs like paracetamol (acetaminophen) and ascorbic acid (vitamin C) can decrease the concentration of rimantadine in the bloodstream by up to 11%. Medications that alkalize the urine, such as acetazolamide and sodium bicarbonate, can enhance the effectiveness of rimantadine by slowing its elimination from the body.

What should I do if I experience side effects from Rimantadine-STI?

Some people may experience side effects such as dry mouth, nausea, vomiting, loss of appetite, dizziness, headaches, or difficulty sleeping. In rare cases, allergic reactions like skin rash, itching, or hives can occur. If any side effects become severe or persistent, it’s important to consult a healthcare provider. Additionally, patients should report any serious or unusual reactions to national health authorities for drug safety monitoring.

What are the overdose symptoms and what should be done?

In case of overdose, symptoms can include agitation, hallucinations, heart arrhythmias, and, in severe cases, death. If an overdose is suspected, immediate medical attention is required.

Treatments may include stomach pumping and supportive care to manage symptoms.

Hemodialysis can help partially eliminate rimantadine from the body.

How should Rimantadine-STI be stored?

Rimantadine-STI should be stored in a cool, dry place at room temperature, away from direct sunlight.

The temperature should not exceed 25°C (77°F).

Keep the medication out of reach of children and do not use it past the expiration date.
