Antihistamines for Long COVID Management

Long COVID can cause neural inflammation and lingering symptoms like fatigue, brain fog, skin rashes, shortness of breath, dizziness, and gastrointestinal discomfort through the release of histamines. Emerging research and clinical reports suggest that antihistamines—particularly H1 and H2 blockers—may help manage these symptoms by calming the immune system and reducing histamine overload.
