Medicines for COVID-19
An illness caused by the SARS-CoV-2 coronavirus that ranges from a mild cold-like illness to severe breathing problems — most people recover at home with rest, fluids and simple pain relief, while antiviral treatments are reserved for people at higher risk of becoming seriously ill.

Quick answer
What is COVID-19?
COVID-19 is the illness caused by the coronavirus SARS-CoV-2. It spreads mainly through tiny droplets and particles breathed out when an infected person coughs, talks or simply breathes, and most people who catch it have a mild to moderate illness.
- How it is treated: For most people, COVID-19 is managed at home in the same way as other viral respiratory infections — rest, plenty of fluids, and simple pain-and-fever relief with paracetamol or ibuprofen to ease aches, headache, sore throat and a high temperature.
- Self-care: Rest, drinking enough fluids and staying off work or school while unwell help recovery and reduce spreading the virus to others.
- When to seek help: Most people can safely recover at home, but some symptoms need urgent help.
What it is
COVID-19 is the illness caused by the coronavirus SARS-CoV-2. It spreads mainly through tiny droplets and particles breathed out when an infected person coughs, talks or simply breathes, and most people who catch it have a mild to moderate illness. Common symptoms include fever, a new continuous cough, a sore throat, a runny or blocked nose, headache, muscle aches, tiredness, and a loss or change to the sense of taste or smell — though the exact mix varies from person to person and changes as the virus evolves. The great majority recover within a week or two without needing any specific treatment. However, the virus can cause more serious illness, particularly affecting the lungs, and the risk of becoming seriously unwell is higher in older people, those with a weakened immune system, and people with certain long-term conditions. Vaccination has greatly reduced the chance of severe illness and hospital admission. Some people develop lingering symptoms lasting weeks or months after the infection has cleared — known as long COVID — which can include ongoing fatigue, breathlessness and difficulty concentrating, sometimes described as "brain fog".
How it is treated
For most people, COVID-19 is managed at home in the same way as other viral respiratory infections — rest, plenty of fluids, and simple pain-and-fever relief with paracetamol or ibuprofen to ease aches, headache, sore throat and a high temperature. Antibiotics do not work against the virus and are not used unless a separate bacterial infection develops. The important extra step is identifying people who are at higher risk of severe illness — such as those who are immunosuppressed or have certain underlying conditions — because specific antiviral treatments and other targeted therapies exist for them. These are not used routinely for everyone; they are arranged through a clinical assessment for eligible people, ideally early in the illness, to reduce the chance of becoming seriously unwell. Vaccination remains the most important way to reduce the risk of severe disease in the first place. Where long COVID develops, care focuses on assessment, support and gradual rehabilitation tailored to the symptoms that persist.

Symptoms that can point to COVID-19
COVID-19 can be one cause of these symptoms. Each guide explains the other possible causes and the red-flag warning signs that mean you should get urgent help:
Beyond medication
Lifestyle and self-care
Rest, drinking enough fluids and staying off work or school while unwell help recovery and reduce spreading the virus to others. Keeping rooms ventilated, good hand hygiene and staying up to date with recommended vaccinations all lower the risk of catching or passing on the infection, and of becoming seriously ill.
When to get help
When to see a doctor
Most people can safely recover at home, but some symptoms need urgent help. Call 999 or go to A&E if you become severely breathless, are struggling to breathe or cannot complete sentences, if your lips or face turn blue or grey, if you have sudden chest pain or tightness, if you become confused, very drowsy or hard to rouse, or if you feel you simply cannot cope. Seek advice sooner if you are in a higher-risk group — for example if you are immunosuppressed or have a serious long-term condition — as you may be eligible for antiviral treatment that works best when started early. Also seek help if symptoms are getting worse rather than better after several days, or if a child is much less responsive than usual, is breathing fast or is not drinking.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
COVID-19: frequently asked questions
What medicines are used for COVID-19?
For most people, no specific medicine is needed — the illness is managed with rest, fluids and simple pain-and-fever relief such as paracetamol or ibuprofen to ease aches, headache, sore throat and a high temperature. Antibiotics do not work against the virus and are not used unless a separate bacterial infection develops. Specific antiviral treatments do exist, but they are reserved for people at higher risk of becoming seriously ill — such as those who are immunosuppressed or have certain conditions — and are arranged through a clinical assessment, ideally early in the illness. Vaccination remains the most important way to reduce the risk of severe disease.
Who can have antiviral treatment for COVID-19?
Antiviral and other targeted treatments are not given to everyone. They are intended for people at higher risk of severe illness — for example those with a weakened immune system or particular underlying conditions — to reduce the chance of being hospitalised. Because they work best when started early in the infection, eligible people are assessed quickly after testing positive. If you are in a higher-risk group, it is worth knowing in advance whether you might qualify, so you can act promptly if you become unwell. For most healthy people, antivirals are not needed and recovery happens with simple home care.
What is long COVID?
Long COVID is the term for symptoms that carry on for weeks or months after the initial infection has cleared. Common features include persistent fatigue, breathlessness, difficulty concentrating or remembering (sometimes called "brain fog"), muscle aches, and disturbed sleep. It can affect people who had only a mild illness to begin with, and symptoms may come and go. There is no single cure; care focuses on assessment, support, pacing of activity and gradual rehabilitation tailored to the symptoms that persist. If symptoms are still troubling you several weeks after a COVID-19 infection, it is worth seeking advice so a plan can be put in place.
Does vaccination still help against COVID-19?
Yes. Vaccination does not always stop you catching the virus, but it substantially reduces the risk of severe illness, hospital admission and death, particularly in older people and those at higher risk. Protection can fade over time and as the virus changes, which is why booster doses are offered to those most likely to benefit. Staying up to date with the doses recommended for you is one of the most effective things you can do to protect yourself, and it also reduces the chance of passing serious illness on to vulnerable people around you. If you are unsure whether you are due a dose, ask your GP or pharmacist.
