What is Oseltamivir?
Oseltamivir is an antiviral drug that inhibits the action of influenza viruses A and B within your body.
Oseltamivir is a medicine used to combat the symptoms of influenza in those who are two weeks old and over and have experienced flu symptoms for two days or less. Oseltamivir can also be administered to protect against influenza in individuals who have been exposed but do not have any symptoms. This medication will not cure the common cold.
It's risky to buy oseltamivir over the Internet or from outside the United States. The distribution and sale of drugs in the U.S. do not comply with the safety-use rules of the Food and Drug Administration (FDA). These medicines could contain hazardous ingredients, or they may not be sold by licensed pharmacies. A few samples that contain "Tamiflu" purchased on the Internet have been discovered to have cloxacillin in them, one type of antibiotic that can cause dangerous adverse effects for those who are allergic to penicillin.
Oseltamivir will treat symptoms of flu that are caused by the influenza virus in people who have been suffering from signs of the virus for less than two days. It is also used to protect against influenza in those who have been exposed but have not yet developed symptoms. This medicine cannot cure the common cold.
Before taking this medication, inform your doctor if you've had an influenza vaccine through the nasal route within the last two weeks or if you suffer from heart disease, kidney disease, lung illness, or any other serious condition or health issue. Tell your doctor if you suffer from any medical condition that causes swelling or disorders of the brain.
You should take oseltamivir for as long as prescribed, even if you start getting better. The symptoms could begin to get better before the infection has been completely cured.
A few people taking this medication have experienced uncommon reactions such as abrupt confusion, delirium, strange behavior, hallucinations, or self-injury. These signs have typically been seen among children. It is unclear if this medication was the primary reason behind these symptoms. But any person taking this medicine must be observed carefully for symptoms of anxiety or strange behavior. Contact a physician immediately if you or your child taking this medicine exhibits any of the symptoms listed above.
