Do I still need to test?
Only if the result would change something — you are eligible for antivirals, you live with someone vulnerable, or you work in health or social care.
Otherwise, stay home while unwell and treat it like any other virus.
Are antivirals available to me?
Only if you are in a defined high-risk group — primarily severe immunosuppression and certain specific conditions.
If that is you, find out your access route before you get ill. The window is five days and it goes quickly.
Why do antivirals interact with so much?
Because ritonavir, which is part of the combination, blocks the enzyme that clears many other drugs. Levels of those drugs can rise substantially.
Statins, some anticoagulants and several heart medicines commonly need pausing or changing — which is why a full medication check comes first.
My test was negative but I feel awful. Now what?
Repeat it in 24 to 48 hours. Lateral flow tests are less sensitive early on.
And treat yourself as infectious meanwhile, particularly around anyone vulnerable.
Can I take ibuprofen?
Yes. The early concern about ibuprofen in COVID-19 was not supported by evidence.
Just do not stack it with cold remedies containing paracetamol.
How long am I infectious?
Most transmission happens in the first five days from symptoms starting.
Avoid contact with anyone at high risk for at least that long, and longer if you are still feverish.
Is my oximeter reading reliable?
Broadly, but with a caveat that matters. Pulse oximeters can overestimate oxygen levels on darker skin.
Use the number alongside how you feel and how you are breathing, never instead of it.
Should I still get vaccinated?
If you are in an eligible group, yes. The purpose now is preventing severe illness rather than preventing infection.
Protection wanes over months, which is why boosters are seasonal rather than one-off.
Why am I still not right months later?
Symptoms beyond twelve weeks are classified as long COVID, and it is a recognised condition rather than something imagined.
It deserves proper assessment — see long COVID.
