Across 228 first-hand reports, people mentioned a side effect 10 times (about 4 per 100 reports). The most common: fatigue, headache, tingling. User reports show what people notice — they can't tell you whether Cerebrolysin is safe for you.

“After ~15 mins of administration of any of these, I'm starting to feel tingling all over the body, weakness, noticeable drop in mood and cognition.”
“it gave me a feeling of young excitement, like the world was new and interesting again. plus it gave me a headache and made me irritable.”
“I’m on my 4th week of cerebrolysin but nothing so far, kinda giving up.”
“Cerebrolysin has helped a number of folks, but I’m hesitant to try that as I’ve seen a handful of credible reports on r/cerebrolysin of it causing small fiber neuropathy.”
Conclusion: The findings of this Cochrane Review do not demonstrate clinical benefits of cerebrolysin for treating acute ischaemic stroke. We found moderate-quality evidence suggesting that serious adverse events may be more common with cerebrolysin use in acute ischaemic stroke.
