Mixing DMT and Tylenol PM
Caution
Carries risk that is worth understanding before combining. Reduce doses and do not use alone.
Can you take DMT with Tylenol PM?
Tylenol PM contains acetaminophen and diphenhydramine. The most concerning part is DMT with Tylenol PM (Diphenhydramine): beyond an ordinary 25–50 mg dose of diphenhydramine, DMT makes its delirium worse and injury more likely. Keep diphenhydramine to that dose. MixSafe rates DMT with Tylenol PM as "Caution" — carries risk that is worth understanding before combining. Reduce doses and do not use alone.

Ingredient by ingredient
DMT + Tylenol PM (Diphenhydramine)Caution
Beyond an ordinary 25–50 mg dose of diphenhydramine, DMT makes its delirium worse and injury more likely. Keep diphenhydramine to that dose.
At 25-50mg, DPH may assist with side effects of the DMT such as nausea and anxiety. At higher dosages, the combination of a deliriant (DPH) and DMT is cautioned against. DMT is likely to increase the deliriant and negative effects of DPH, in addition to increasing the risk of severe injury and mental trauma.

DMT + Tylenol PM (Acetaminophen)Low risk, no synergy
Neither substance is expected to meaningfully change the other. Both still carry their own individual risks.
No specific interaction is documented. Acetaminophen's main risk is dose-dependent liver injury, so the thing to watch in any combination is total daily intake across all products (roughly 4g/24h) and anything else straining the liver.
