Across 141 first-hand reports, people mentioned a side effect 9 times (about 6 per 100 reports). The most common: dissociation, headache, fatigue. User reports show what people notice — they can't tell you whether Ketamine is safe for you.
“killed my anxiety and elevated my mood a lot when it stopped acting...had an abnormality on my kidneys (elevated creatinine)”
“Lol I had a total break from reality with a prescribed ketamine lozenge. A very scary trip to say the least. Its not side effect free lol.”
“I'm 18 and suffer from treatment resistant depression (no, Ketamine didn't work)”
“I thought it was helping my anxiety and depression but in the end it became a full blown addiction... I’m off it now entirely and I feel much better.”
Conclusion: Compared with placebo, NSAIDs, ketamine, and mid- to high-potency opioids are effective in reducing acute pediatric pain. NSAIDs provide the greatest benefits and least harm, suggesting that they should be the first-line therapy for acute painful conditions in children.
