Lancet Infectious Diseases published a large randomized controlled trial showing antihistamines, anti-inflammatory drugs and blood thinners produced only modest, short-term improvement in long COVID.
5 to 6 years into the illness, many of the sickest patients still need effective treatments, underscoring why researchers and clinicians view large clinical trials as critical.
10 weeks of cognitive rehabilitation in a separate small UCL-led trial helped some patients with symptoms such as brain fog make progress toward returning to work and hobbies.
Further trials are already in progress or planned, with researchers seeking stronger evidence and more durable options for a condition that remains disabling for many patients.
