If you can’t take Tamiflu (oseltamivir) or it’s not available, you’ve still got options. Some drugs fight the flu virus directly, others ease symptoms while your body clears the infection. Which one fits you depends on timing, age, health risks, and how sick you are.
There are three main prescription antiviral alternatives. Zanamivir (Relenza) is an inhaled medicine that works like Tamiflu but isn’t safe for people with asthma or COPD. Peramivir (Rapivab) is a single-dose IV drug used mainly in hospitals for severe cases. Baloxavir (Xofluza) is a one-time oral pill that's handy because it often reduces virus levels quickly. All of these antivirals work best when started within 48 hours of symptoms, and your doctor will pick the right one based on your age, lungs, and other health issues.
Side effects and limits matter. Zanamivir can cause wheeze and breathing trouble in sensitive people. Peramivir requires an IV so it’s given in a clinic or hospital. Baloxavir may be less studied in some groups, and antiviral resistance can develop, so doctors weigh pros and cons before prescribing. Pregnant people and very young children need special consideration — oseltamivir is usually preferred in pregnancy, but your clinician will advise what’s safest for you.
Most people recover with supportive care. Stay hydrated, rest, and use fever reducers like acetaminophen or ibuprofen at recommended doses. For cough and congestion, saline nasal spray, steam, or a humidifier help more than many OTC sprays. Don’t give aspirin to children or teens with flu symptoms because of the risk of Reye’s syndrome. If you have heart disease, diabetes, or a weakened immune system, start medical advice early — even if symptoms seem mild.
Antibiotics don’t treat the flu. They’re only needed if a bacterial complication, like pneumonia, shows up. Watch for red flags: trouble breathing, chest pain, fainting, severe dizziness, or confusion — those require urgent care.
All effective flu antivirals need a prescription. If you think you should start treatment, call your doctor or use a trusted telehealth service right away — remember the 48‑hour window. When ordering online, use reputable pharmacies with a clear license, a real pharmacist contact, and a valid prescription requirement. Sites that skip prescriptions or offer suspiciously low prices are red flags.
Finally, prevention beats treatment: annual flu vaccination, good handwashing, and staying home when sick cut the chance you’ll need antivirals at all. If you’re unsure which option fits you, a quick call to your healthcare provider will point you in the right direction.
