- Injection site reactions (erythema, mild swelling, tenderness)
- 8–15%
- Within 2–4 hours post-injection
- 12–48 hours
- Standard in subcutaneous peptide administration. Technique-dependent
- Expected pharmacological response, clinically insignificant, no intervention required
- Transient fatigue or malaise
- 3–5%
- 24–72 hours after initial dose
- 4–5 days (resolves during continued administration)
- Correlates with immune system activation, most common in elderly or immunocompromised subjects
- Likely reflects energy reallocation toward immune function, self-limiting
- Lymphadenopathy (reactive lymph node swelling)
- <2%
- Days 3–7 of administration
- 7–14 days post-treatment
- Observed in subjects with baseline low lymphocyte counts or thymic atrophy
- Pharmacodynamic response indicating increased lymphocyte trafficking, not pathological
- Headache (non-specific)
- <1%
- Variable, no clear temporal pattern
- 6–24 hours
- Isolated case reports, unclear causality. May be coincidental
- Insufficient data to establish causal relationship with Thymalin
- Allergic reaction (urticaria, rash)
- <0.5%
- Within hours of first dose
- 48–72 hours with antihistamine
- Single published case in subject with multiple drug sensitivities
- Likely hypersensitivity to bovine-derived peptide fraction, screen for animal protein allergies
- Serious adverse events (organ toxicity, anaphylaxis, cytokine storm)
- 0% in published literature
- Not observed
- N/A
- Zero documented cases across hundreds of published research subjects
- Exceptionally safe profile relative to other immunomodulating agents
