Naphazoline and Pheniramine [NAPHCON-A] Eye Drop 

For proper use of eye drop:

• Wash your hands with soap and water.
• Shake the bottle.
• Tilt your head backwards and look up.
• Gently pull the lower eyelid down to form a pocket and squeeze the bottle to apply one drop into your eye. To prevent the tip of the bottle from getting contaminated, make sure the tip does not touch the eye or any other surface.
• Close your eyes and press down gently on the inner corner of your eye for 1 to 2 minutes to allow the medicine to be absorbed and prevent it from being drained into the back of your throat.
• If you need to use more than one type of eye drops, wait for at least 5 to 10 minutes before applying the next eye drop. This is to prevent the first drop of medicine from being washed away by the second drop of medicine before it has time to work. This also prevents any interactions between different eye drops.
• If your doctor prescribed both eye drops and eye ointments, you should use the eye drops first.

For contact lens wearers:

• Remove your contact lens before each application of medication to avoid eye irritation.
• Wait at least 15 minutes before putting your lenses back in. Otherwise, your lens may be damaged by the preservative present in the eye drops.

Headache, blurred vision

• These side effects are mild and will subside after some time. Do not drive or operate machinery immediately after using the eye drops.

Burning, stinging, redness or irritation of the eye

• If the discomfort continues for more than a few minutes, discontinue the medication, and rinse the affected eye with normal saline eye wash.
• Do not use the eyedrops consecutively for more than 3 days as prolonged and/or excessive use may lead to worsening redness of the eyes.

These side effects are usually mild and go away after some time. However, if the symptoms are bothersome, do not go away or become worse, stop these medications and consult your healthcare professional.
