Oseltamivir review by Medicalook.com
|
Oseltamivir is a drug treatment for the influenza virus. It was developed in the laboratories of Gilead Sciences and is currently marketed under the brand name Tamiflu by Hoffman-La Roche, a Switzerland-based pharmaceutical company. Oseltamivir is marketed through Chugai pharmaceutical Co. in Japan under the same brand name. in countries where it is made available, Oseltamivir is available only by a doctor’s prescription.
A recent FDA notice informed healthcare providers about the neuropsychiatric events linked with Oseltamivir use. The report is mostly based from patients treated in Japan where over 50 million users have been recorded. Patients with influenza who were treated with Oseltamivir have been found with abnormal mental behavior, which can be fatal. The findings were mostly associated with young patients. The adverse behavioral effect that includes delirium occurs abruptly and develops rapidly.
That FDA warning is reason enough people should not use Oseltamivir without the supervision of a qualified doctor. Oseltamivir use can be damaging more than it is beneficial. Your doctor must assess the advantage and disadvantage of using it in your case before even making the prescription.
As with any drug use, Oseltamivir treatment must be started only after certain medical conditions and factors have been ruled out. Oseltamivir is contraindicated to patients with allergy to the drug and its components. It is also not advised to be used by patients with immune system disorders and heart, lung, liver, or kidney disease. Pregnancy is also a major concern in connection with an Oseltamivir treatment. The drug may cause harm to the fetus and even to a nursing baby who may absorb the drug through breastfeeding.
Oseltamivir comes in capsule and liquid suspension forms. To provide relief from the symptoms of flu, Oseltamivir is used twice daily; to prevent flu, it is taken once a day. Oseltamivir is an antiviral drug. Its use must be continuous and regular to be effective. Patients need to maintain a certain level of Oseltamivir in the blood to eliminate the virus completely. You must take Oseltamivir for the duration of your prescription. Your symptoms may improve earlier but that does not guarantee that the virus has been killed and its spread is stopped.
With the warnings up, Oseltamivir users must be really cautious. Keep a close watch on your symptoms. Mild episodes of nausea, vomiting, stomach pain, diarrhea, headache, cough, dizziness, and insomnia are common side effects of the drug. What you and your caregiver need to keep a close watch for is the change in your behavior. Becoming confused or suicidal must prompt you to seek medical attention immediately. Hives, skin rash, breathing difficulty, itching, and hoarseness are physical manifestations that must not be ignored as well.
Keep a regular appointment to see your doctor during an Oseltamivir treatment. Your doctor needs to monitor your symptoms and your bodily reactions to ensure your safety with the drug. Being closely monitored by a physician will help you spot any abnormality or problem sooner than later and receive appropriate treatments for it.
