Low risk, no synergy

Neither substance is expected to meaningfully change the other. Both still carry their own individual risks.

Do this

Treat each one as if you had taken it alone: its own dose, its own risks.

Reported

7-OH is not sold combined with acetaminophen, so the hidden-dose problem behind the Percocet and Vicodin warning does not apply, and no interaction between the two is documented. Keep to the label's daily limit across every product you take.

What “Low risk, no synergy” means
