Best medicine for the flu
For most healthy people the flu is self-limiting and managed at home with rest, fluids, and over-the-counter medicines that ease fever, aches, and cough — there is no OTC cure that kills the virus. Prescription antiviral drugs can shorten illness by about a day but a doctor reserves them mainly for people who are very sick or at high risk of complications.

Over-the-counter options
Available without a prescription — follow each label.
Tylenol Analgesic / antipyretic (fever reducer) Our rating 70/100 | First-line for lowering fever and relieving the headache, muscle aches, and sore throat of flu. Don't exceed 4,000 mg/day, and watch for it hidden in multi-symptom 'cold & flu' combo products so you don't double-dose. |
Advil, Motrin NSAID (anti-inflammatory pain/fever reducer) Our rating 72/100 | An alternative to acetaminophen for fever and body aches; some providers suggest alternating the two. Take with food and avoid if you have stomach ulcers, kidney problems, or are advised against NSAIDs. |
Delsym, Robitussin DM Antitussive (cough suppressant) | Temporarily quiets a dry, hacking cough by reducing the cough signal in the brain. It eases the symptom but does not treat the infection or speed recovery. |
Mucinex Expectorant | Helps thin and loosen chest mucus so a productive, congested cough is easier to clear. Drink plenty of fluids alongside it. |
pseudoephedrine Sudafed Oral decongestant | Relieves a stuffy, blocked nose and sinus pressure. Check with a pharmacist or doctor first if you have high blood pressure, heart disease, or prostate problems; sold from behind the pharmacy counter. |
Prescription options
A doctor may prescribe these — not for self-treatment.
Tamiflu Neuraminidase inhibitor (antiviral) | A doctor may prescribe this oral antiviral, especially for people very sick or at high risk; it works best started within 1–2 days of symptoms and can shorten illness by about a day. Prescription only — not something to start on your own. |
Xofluza Cap-dependent endonuclease inhibitor (antiviral) Our rating 70/100 | A doctor may prescribe this as a single-dose oral antiviral, again most useful when begun within the first day or two of symptoms. Prescription only. |
Relenza Neuraminidase inhibitor (inhaled antiviral) Our rating 70/100 | A doctor may prescribe this inhaled-powder antiviral; it is generally avoided in people with asthma or COPD because it can trigger wheezing. Prescription only. |
Rapivab Neuraminidase inhibitor (IV antiviral) | A doctor may give this as a single intravenous dose, typically in a clinical setting for people who can't take oral medication. Prescription only. |
How to choose
Start by matching the medicine to your worst symptom: acetaminophen or ibuprofen for fever and aches, a decongestant (pseudoephedrine) for a blocked nose, dextromethorphan for a dry cough, and guaifenesin for a chesty, mucus-filled cough — and rest plus plenty of fluids underpin all of it. Multi-symptom "cold & flu" products bundle several of these, which is convenient but makes it easy to accidentally double up on acetaminophen, so always read the active-ingredient list. Antibiotics do nothing for the flu because it is a virus. Prescription antivirals are a doctor's decision: they help most when started within the first day or two and are aimed mainly at people who are very sick or at high risk (age 65+, pregnant, young children, or those with conditions like asthma, diabetes, heart, or lung disease). Never give aspirin to children or teenagers because of the risk of Reye syndrome.
When should I see a doctor?
Get urgent or emergency care for any breathing problem — trouble breathing, shortness of breath, or chest pain or pressure — as well as bluish lips or face, coughing up blood, sudden dizziness or confusion, seizures, severe or persistent vomiting, or a very high fever that won't come down. In children, also seek help for fast or labored breathing, dehydration (no tears, much less urine), not waking or interacting, or a fever with a rash. Contact a clinician promptly (rather than waiting it out) if you are 65 or older, pregnant, have a weakened immune system, or have a long-term condition such as asthma, diabetes, or heart disease, or if symptoms last beyond about a week, improve and then come back worse, or you're worried about a baby or young child — these are the people antivirals may help most and who are most at risk of complications.
