Safety Summary

Selank is generally well tolerated with minimal adverse effects. No serious adverse events, dose-limiting toxicities, dependence, tolerance, or withdrawal phenomena have been documented in human trials or preclinical studies. The Medvedev et al. 2015 study (PMID:26356395) found that adding selank to phenazepam actually decreased undesirable benzodiazepine side effects (attention/memory impairment, asthenia, sedation, sexual disturbances). No evidence of carcinogenicity in preclinical studies. Embryonic stem cell toxicity testing showed selank produced no toxic effect during embryonic/fetal period (PMID:29063333).

Clinical check-in

If real-world use or exposure is being considered, review potential interactions, contraindications, and monitoring needs with a licensed clinician rather than relying on summary copy alone.
