Iatrogenic harm (caused by treatment)
Symptoms caused or worsened by supplements, medications, or unproven treatments — common in this community.
People with Long COVID are at high risk of self-directed polypharmacy. Specific, documented harms include vitamin B6 toxicity causing neuropathy (which can be mistaken for a new symptom), zinc-induced copper deficiency causing a myeloneuropathy, vitamin-D megadosing causing hypercalcemia, serotonin syndrome from 5-HTP with an SSRI, dangerous drug interactions, and outright toxic 'treatments' like chlorine-dioxide/MMS. The fix is cheap and high-value: a full medication-and-supplement reconciliation, then stopping anything unproven and harmful. Subtract before you add.
How it's tested
Medication & supplement reconciliation
An expert reviews every prescription, over-the-counter drug, and supplement for toxicity, interactions, and unproven/harmful agents. Cheap, fast, and frequently missed.
Treatment options & their evidence
Graded honestly — including treatments that failed in good trials, which is worth knowing.
Deprescribe / stop the offending agent
Strong evidenceStopping harmful or unproven supplements/medications and reconciling interactions removes a cause of symptoms. 'Subtract before you add.'
Caution: Some medications must be tapered, not stopped abruptly — do this with a clinician.
