As the flu season persists in the United States, Tamiflu remains a prominent choice for treating influenza. This antiviral medication, approved by the Food and Drug Administration (FDA), has become a staple in combating flu symptoms. Tamiflu can potentially shorten the duration of illness by about a day, provided it is administered within 48 hours of symptom onset. However, its use is typically recommended for individuals at higher risk of severe flu complications.
Across the U.S., at least 24 million people have contracted the flu this season, resulting in 13,000 fatalities. The severity of the current flu season has prompted many to consider antiviral treatments. Dr. Geeta Sood remarked on the intensity of this year's flu season, noting its high incidence and severity.
“It’s one of our more severe flu seasons. The incidence of flu we’re seeing is very high, and the disease that we’re seeing seems to be a little bit more severe from previous seasons,” – Geeta Sood, MD, ScM
Tamiflu stands out as the most commonly used antiviral for influenza in the U.S. Its widespread availability in pharmacies and coverage by nearly 70% of insurers contribute to its popularity. Additionally, Tamiflu has the distinction of being one of four FDA-approved antiviral medications for treating influenza, particularly effective against both influenza A and B in individuals as young as 14 days old.
The recommended dosage for individuals over the age of 12 involves taking Tamiflu twice daily for five days. While the drug is generally safe and can be taken with other medications without known interactions, taking it with food may alleviate side effects like vomiting, nausea, and headache. Despite these potential discomforts, Tamiflu remains a crucial option for those at risk.
“A lot of safety and efficacy studies have been done on it, and it’s the one a lot of physicians feel comfortable prescribing because we have so much data on it,” – Antoon
“They all work about the same for influenza,” – Antoon
“We have good head-to-head studies on these antivirals. They all have around the same reduction in duration of symptoms.” – Antoon
Patients on Tamiflu may experience less common side effects such as stomach pain, nosebleeds, headache, and fatigue. Nevertheless, experts suggest that these issues are minor compared to the drug's benefits. Even if the 48-hour window has passed, Tamiflu might still be advantageous, especially for patients with underlying conditions such as asthma, diabetes, or heart disease.
“Where some people nitpick these antivirals is that a day of symptoms isn’t that significant,” – Antoon
“But it can add up with [the reduced] risk of transmission.” – Antoon
“That helps your body fight off the infection better and faster,” – Sood
In cases where Tamiflu is deemed necessary, specific groups are advised to consider its use carefully. Pregnant individuals, young children with health concerns, and those with chronic conditions should evaluate the benefits of antiviral medication if they contract the flu.
Looking ahead, there is potential for Tamiflu to become even more accessible. Discussions are underway regarding the possibility of making it available without a prescription, which could streamline treatment during flu season and offer timely relief.
