WHY ARE SULFONAMIDES AND NIACIN CONTRAINDICATED FOR GH3?

Both sulpha drugs and straight niacin (not niacin as part of a multi-vitamin) can neutralise the effects of the procaine. However GH3 does not interact with them in a harmful manner. PABA is antagonistic to sulphonamides and therefore will cause a mutual decrease in effectiveness. Niacin dilates the blood vessels to such an extent that procaine is forced quickly out of the system.
