As the flu season approaches or intensifies in Nairobi, many people begin feeling achy, feverish, and just “off.” It’s easy to mistake these symptoms for something that needs strong medicine right away.
But here’s the important truth: most flu cases are caused by viruses, and antibiotics do not help against viral infections like influenza. Using antibiotics unnecessarily can do more harm than good.
In this article, we’ll explain how the flu works, why antibiotics won’t cure it, how to manage common symptoms safely, and how to know when to see a doctor.
The focus is on helping you stay well and comfortable in Kenya without contributing to antibiotic misuse.
The flu, short for influenza, is a respiratory illness caused by influenza viruses. These viruses infect your nose, throat, and sometimes lungs.
Flu symptoms often come on quickly, and they can be quite intense. You might feel a sudden fever, muscle aches, headache, sore throat, and persistent tiredness.
These symptoms differ from a simple cold, which tends to be milder with mostly nasal symptoms and little fever.
Most flu illnesses resolve on their own with supportive care, meaning you treat the symptoms while your immune system fights the virus.
A study of flu infections shows that antiviral medications can help shorten duration and severity if started early, but antibiotics are ineffective against viruses.

It’s very common for people to think antibiotics are “strong medicine” that cure coughs, fevers, and sore throats. But antibiotics only work against bacterial infections. Since the flu is caused by a virus, antibiotics will not:
Taking antibiotics when they are not needed can disrupt good bacteria in your body, cause uncomfortable side effects, and contribute to antibiotic resistance — a serious public health problem where bacteria become harder to treat over time.
In Kenya, the Pharmacy and Poisons Board has also warned the public not to use antibiotics to treat viral flu, emphasizing rest, hydration, and nutritious food as better ways to recover.
Flu symptoms in Kenya are similar to what people experience elsewhere. These can include:
These symptoms usually develop suddenly and can make you feel miserable for several days. In most healthy adults, symptoms start to improve within a week, but residual tiredness and cough can last longer.

If you have flu symptoms but you are otherwise healthy, there are several effective and safe ways to ease your discomfort without antibiotics.
Rest gives your body a chance to focus its energy on fighting the virus. It's normal to feel tired when you are sick. Try to stay home, sleep more, and avoid strenuous activities until you start feeling better.
Flu can make you sweat more and lose fluids, especially if you have a fever. Drinking plenty of water, warm soups, herbal tea, or electrolyte drinks will help keep you hydrated. Hydration also helps relieve sore throat and clears mucus.
Over-the-counter medicines can ease specific symptoms. For example:
A pharmacist can help you choose the right options based on your symptoms and any other medicines you take.
Eating light, nutritious foods like fruits, soups, and broths can support your immune system while giving your body the strength it needs to recover. Avoid heavy, greasy meals while you are sick.
Although antibiotics won’t help, antiviral medications can be useful in certain situations.
Antivirals, such as Zovirax Cold Sore Cream and related drugs, are different from antibiotics. They can help decrease how long the flu lasts and reduce the severity of symptoms — especially when started within the first 48 hours of getting sick.
However, these medications are usually prescribed by a healthcare provider and are most helpful for people at higher risk of complications, such as:
If you fall into one of these groups or have severe symptoms, it’s wise to contact a clinician for assessment.
Most people can manage flu symptoms at home, but you should seek professional help if you experience:
These may be signs of complications, including bacterial infections that truly do require antibiotics under medical supervision.
Managing flu symptoms in Nairobi doesn’t have to involve antibiotics. Most cases of flu will improve with rest, hydration, nutrition, and supportive care.
Unnecessary use of antibiotics can harm your health and contribute to the growing global problem of antibiotic resistance. If in doubt, ask a qualified healthcare provider or pharmacist for advice tailored to your situation.
1. Can antibiotics cure the flu?
No. Antibiotics do not work against viral infections like the flu. They are only effective against bacterial infections. Taking them for the flu does not make you recover faster and can be harmful.
2. What should I take for fever and body aches from the flu?
Medicines like paracetamol or ibuprofen can help reduce fever, headaches, and muscle pain. Always follow the recommended dose and consider asking a pharmacist if you’re unsure.
3. Are antiviral drugs available in Kenya?
Yes — but they generally require a prescription from a healthcare provider. Antivirals like oseltamivir may be recommended for people at higher risk or with severe symptoms if started early.
4. How long does the flu usually last?
Flu symptoms often improve within 5–7 days, but some discomfort (like fatigue or cough) can last longer. Stay hydrated and at home until symptoms ease.
