  3. Hold the packet at the notch. Hold the packet as close to your mouth as possible and tear along the red arrow line.
  4. Lift up your tongue.
  5. Pour all of the GoNitro powder in the packet under your tongue.

To treat an angina attack place the contents of one or two packets of GoNitro powder under the tongue at the onset of the attack. An additional packet can be administered every five minutes as required.

Seek medical help straight away if chest pain persists after three packets of GoNitro have been administered.
