Ventizolve contains naloxone, an opioid blocker, used to quickly reverse the effects of known or suspected opioid overdose in adults.
One spray (1.26 mg naloxone) into one nostril.
Support the neck, tilt the head back. Insert the nozzle into one nostril. Press the plunger firmly until it clicks to give the dose. Remove the nozzle from the nostril.
If the first dose doesn't help, a second dose can be given in the other nostril after 2-3 minutes. If symptoms do not significantly improve after two doses, other causes should be considered.
