Mcosvir Syrup

Mcosvir Syrup is an oral antiviral medicine containing oseltamivir in syrup form, with the labeled amount provided in each bottle. It belongs to the neuraminidase inhibitor class and is used to treat and help prevent influenza A and influenza B, the flu. Mcosvir Syrup is most useful when started soon after flu symptoms begin or after a known exposure, as directed by a clinician. This product is manufactured by Mcneil & Argus Pharmaceuticals and is supplied in a strip/box of 10 bottles.

How it works: Oseltamivir works by blocking a flu virus enzyme called neuraminidase, which the virus needs to spread from one infected cell to another. As a syrup, Mcosvir Syrup lets the medicine be measured and taken by mouth in an easy-to-swallow liquid form.

Mcosvir Syrup is the syrup strength/form of oseltamivir, which can be easier for children or adults who have trouble swallowing capsules or who need an exact measured liquid dose. Because this is an oral liquid, it may be chosen when a prescriber wants flexible dosing by volume and a form that is easier to swallow than solid tablets or capsules. If a doctor selects Mcosvir Syrup, it is because the liquid form best fits the patient’s age, weight, swallowing ability, and treatment plan.

• Treatment of influenza A
• Treatment of influenza B
• Flu prevention after exposure
• Prevention during flu outbreaks in selected patients

• Shake the Mcosvir Syrup bottle well before each dose so the medicine is evenly mixed.
• Measure each dose carefully with an oral syringe or marked measuring device, not a kitchen spoon.
• Take it exactly at the times prescribed by your doctor, even if you start feeling better.
• It may be taken with or without food; taking it with food can help reduce stomach upset.
• Start treatment as soon as possible after flu symptoms begin, because it works best when started early.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.

Mcosvir Syrup provides oseltamivir as labeled in each bottle, and the exact dose is determined by the prescriber based on the patient’s age, weight, and whether it is being used for treatment or prevention. It is commonly taken twice daily for treatment or once daily for prevention, but the doctor decides the schedule and the maximum daily amount for this specific patient. Do not change the dose of Mcosvir Syrup on your own, especially because liquid dosing must be measured accurately.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Oseltamivir may include:

• Nausea
• Vomiting
• Stomach pain
• Headache
• Dizziness
• Diarrhea
• Tiredness

• Use extra care if you or the patient has kidney disease, because the dose may need adjustment.
• Tell the prescriber if the patient is pregnant or breastfeeding before using Mcosvir Syrup.
• Use caution in patients with a history of severe allergy to oseltamivir or any ingredient in the syrup.
• Because this is a liquid, measure each dose exactly; household teaspoons can cause dosing errors.
• If the syrup contains sugars or sweeteners, ask your pharmacist whether this matters for diabetes or dental care.
• This medicine does not replace the flu vaccine and does not treat common cold or COVID-19.
• Use caution when driving or operating machinery if dizziness or confusion occurs.

• Live attenuated influenza vaccine given through the nose may need to be timed away from oseltamivir use.
• Probenecid may increase oseltamivir levels in the body.
• Other medicines that cause significant nausea or vomiting may make side effects harder to tolerate.
• Tell your clinician about all prescription drugs, over-the-counter medicines, and supplements before starting Mcosvir Syrup.

Store Mcosvir Syrup at room temperature as directed on the package, tightly closed and out of reach of children, and do not use it past the expiration date.
