Uses For Ivy Block
Bentoquatam protects the skin like a shield against poison ivy, poison oak, and poison sumac by physically blocking skin contact with their resin. The best protection against getting these conditions is to avoid contact with these plants. This medicine does not dry oozing and weeping caused by the rash of poison ivy, poison oak, or poison sumac.
Bentoquatam is available without prescription.
