What Did a Stop-and-Restart Timeline Add to a Suspected Supplement Reaction?
When a symptom changes after a product is stopped or restarted, the sequence can strengthen a hypothesis about exposure. It still matters whether the symptoms resolved during the gap.
What the patient reported
A patient took Vertigoheel for dizziness and stopped after about two days when he noticed changes in how he felt. Some symptoms persisted after discontinuation. About a week later, dizziness returned and he took another tablet. He then reported new auditory symptoms. The authors considered a possible relationship with the preparation.
Why a dated account matters
This was a reported re-exposure during an evolving illness, with no symptom-free interval clearly separating all effects. The sequence cannot identify a responsible ingredient or prove a causal relationship. A case review can distinguish the initial exposure, persistent symptoms, subsequent dose and new symptoms without collapsing them into one start date.
