Flu-like symptoms are n/v, diarrhea, diaphoresis, blurred vision, insomnia.

• A. Flu-like symptoms
• B. Acute withdrawal effects
• C. Dopaminergic rebound
• D. Cholinergic rebound

Answer: (A)

These signs form a classic flu-like withdrawal picture. When a drug with central nervous system effects is reduced or stopped, the body can swing into a hyperactive autonomic state. Nausea, vomiting, diarrhea, and diaphoresis reflect this gastrointestinal and sweat-driven response, while insomnia and blurred vision come from increased arousal and sympathetic activity. The overall presentation is described as flu-like because it resembles a bad flu in its symptomatic mix and brings with it the same kind of systemic discomfort. This pattern isn’t about a rebound of a specific neurotransmitter like dopamine or acetylcholine; those rebound concepts describe different withdrawal dynamics tied to particular drug classes. The cluster described aligns best with the generic “flu-like withdrawal” label, guiding clinicians toward supportive care and symptom management.
