What are the possible risks of being in the study?

• Dexamethasone may disturb sleep and increase the risk of infections. In people with diabetes it can raise blood sugar.  

• Empagliflozin may cause urine or genital tract infections, like thrush. If you have diabetes, empagliflozin also lowers blood sugar in people taking insulin or some other diabetes treatments so your doctors may adjust the doses of those. It may also cause a condition called ketoacidosis (which rarely can be life-threatening), which is treated with a drip and insulin. You will be monitored for this with daily fingerprick blood or urine tests. 

• Oseltamivir may cause headache, tummy upset and allergic reactions. 

• Baloxavir rarely causes allergic reactions, but has no other known side effects. 

• Sotrovimab is given by intravenous infusion and may cause allergic reactions during the infusion, but severe reactions have been rare. 

• Molnupiravir may cause dizziness, headache, tummy upset and rashes. (Women taking molnupiravir should not get pregnant while taking the drug or for 4 days afterwards.) 

There is also the unlikely possibility of a severe reaction to any study drug. At some sites, other treatments may also be assessed. Please ask your hospital doctor if you would like more information. Once you have been included in the study, you and your doctors will know which treatment the computer has allocated for you. Your doctors will be aware of whether there are any particular side effects that they should look out for.  

Women who are pregnant may be included, however, the effect of some of the treatments on unborn babies is uncertain.
