What key warnings should I know about before taking this medicine?

• This medicine does not mix well with many medicines. Serious reactions may occur. Check all medicines with healthcare provider.

Reasons not to take this medicine

• If you have an allergy to tetrahydrozoline or any other part of this medicine.

• Tell healthcare provider if you are allergic to any medicine. Make sure to tell about the allergy and how it affected you. This includes telling about rash; hives; itching; shortness of breath; wheezing; cough; swelling of face, lips, tongue, or throat; or any other symptoms involved.

• If you have taken isocarboxazid, phenelzine, or tranylcypromine in the last 14 days. Monoamine oxidase inhibitors (eg, isocarboxazid, phenelzine, and tranylcypromine) must be stopped 14 days before this medicine is started. Taking the two together could cause dangerously high blood pressure.

How does it work?

• Tetrahydrozoline shrinks swollen nasal tissue and opens up passages.

• It shrinks blood vessels in the eye.

How is it best taken?

Nasal:

• Do not take this medicine by mouth. For the nose only. Keep out of mouth and eyes (may burn).

• Blow your nose before use.

• Do not touch the container tip to the eye, lid, or other skin.

• Tilt head back and drop medicine into eye.

• After using medicine, keep your eyes closed. Apply pressure to the inside corner of the eye. Do this for 3-5 minutes. This keeps the medicine in your eye.

• Separate each eye medicine by 5 minutes.
