Antiflu 12mg/ml Syrup

Introduction

Antiflu is a prescription medication that contains the active ingredient Oseltamivir Phosphate. It is available in syrup form and is commonly used to treat and prevent influenza (commonly known as the flu).

Uses

Antiflu is primarily prescribed for the treatment of influenza in patients aged 1 year and older. It is effective against both influenza A and B viruses. This medication works by inhibiting the growth and spread of the influenza virus in the body, helping to alleviate symptoms and reduce the duration of the illness.

Dosage and Administration

The recommended dosage of Antiflu for adults and children aged 13 years and older is 75 mg twice daily for 5 days. For children aged 1 to 12 years, the dosage is based on their body weight. Follow the dosage instructions provided by your healthcare professional.

Antiflu should be taken with food to help minimize potential stomach upset. The syrup can be measured using the provided dosing cup or an oral syringe. Shake the bottle well before each use to ensure proper mixing of the medication.

Mechanism of Action

Oseltamivir Phosphate, the active ingredient in Antiflu, belongs to a class of medications called neuraminidase inhibitors. It works by inhibiting the activity of the neuraminidase enzyme, which is essential for the spread of the influenza virus in the body. By blocking this enzyme, Oseltamivir Phosphate helps to reduce the severity and duration of influenza symptoms.

Side Effects

Common side effects may include nausea, vomiting, headache, and diarrhea. These side effects are usually mild and go away on their own. However, if they persist or become severe, consult your healthcare professional.

In rare cases, Antiflu may cause more serious side effects, such as allergic reactions or neuropsychiatric events. If you experience any signs of an allergic reaction, such as rash, itching, swelling, or difficulty breathing, seek immediate medical attention. Additionally, if you experience any unusual changes in mood or behavior, including confusion or self-harm ideation, discontinue the medication and contact your healthcare professional.

Drug Interactions

inform your healthcare professional about all medications you are currently taking, including over-the-counter drugs, herbal supplements, and vitamins. Certain medications may interact with Antiflu, potentially affecting its effectiveness or increasing the risk of side effects. Some common and serious drug interactions include:

• Influenza Vaccines: Antiflu may reduce the effectiveness of influenza vaccines. It is recommended to avoid receiving live attenuated influenza vaccines while taking this medication.
• Probenecid: Probenecid may increase the concentration of Oseltamivir Phosphate in the body, potentially leading to an increased risk of side effects. Your healthcare professional may need to adjust the dosage of Antiflu if you are also taking probenecid.

Consult your healthcare professional before starting or stopping any medications while taking Antiflu.
