Tetrahydrozoline
 
Indication
Allersine (Tetrahydrozoline) is an antihistamine that inhibits the body's release of a chemical called histamine. Histamine can produce allergy symptoms such as sneezing, runny nose, and watery eyes.
Allersine ophthalmic is used to treat itching of the eyes caused by allergy to dust, pollen, animals, or other allergens. 

Allersine ophthalmic may also be used for other purposes not listed in this medication guide.
 
Instruction
Use this medication exactly as directed on the label, or as it has been prescribed by your doctor. Do not use the medication in larger amounts, or use it for longer than recommended.

Wash your hands before using the eye drops.

If you wear contact lenses, remove them before applying Allersine ophthalmic. This medication may contain a preservative (benzalkonium chloride) that may cause discoloration of contact lenses.

To apply the eye drops:

Tilt your head back slightly and pull down your lower eyelid. Hold the dropper above the eye with the dropper tip down. Look up and away from the dropper as you squeeze out a drop, then close your eye. Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct. If you use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.
Do not allow the dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye. 

After using the eyedrops, wait at least 10 minutes before putting contact lenses into your eyes.
Do not use the eye drops if the liquid has changed colors or has particles in it. Call your doctor for a new prescription. Store the drops at room temperature away from heat and moisture. Keep the bottle tightly closed when not in use.
