Warnings and Precautions

Consult your doctor, pharmacist, or nurse before starting to use Bentifen.

Using Bentifen with other medications

If you need to apply any other eye medication in addition to Bentifen, wait at least 5 minutes between the application of each product.

Inform your doctor or pharmacist if you are using, have recently used, or may need to use any other medication. This is especially important in the case of medications used to treat:

  • Depression, anxiety, and sleep disorders
  • Allergies (e.g., antihistamines)

Using Bentifen with food, beverages, and alcohol

Bentifen may increase the effects of alcohol.

Pregnancy and Breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Driving and Using Machines

Bentifen may cause blurred vision or drowsiness. Do not drive or use machines until these effects have disappeared.

Bentifen contains benzalkonium chloride

This medication contains 2.6 micrograms of benzalkonium chloride per drop.

Benzalkonium chloride can be absorbed by soft contact lenses and may alter their color. Remove contact lenses before using this medication and wait 15 minutes before putting them back on.

Benzalkonium chloride may cause eye irritation, especially if you have dry eye or other corneal diseases (the transparent layer on the front of the eye). Consult your doctor if you feel any unusual sensation, itching, or pain in the eye after using this medication.

3. How to use Bentifen

Follow the administration instructions of this medication exactly as indicated by your doctor or pharmacist. If in doubt, ask your doctor or pharmacist.

Follow the administration instructions of the medication contained in this package leaflet or as indicated by your doctor, pharmacist, or nurse. If in doubt, ask your doctor, pharmacist, or nurse.

The recommended dose in adults, elderly, and children (3 years or older) is one drop in the affected eye(s) twice a day (morning and night).

Instructions for use

  1. Wash your hands.
  2. Open the bottle. Do not touch the tip of the dropper after opening the bottle.
  3. Tilt your head back (Fig. 1).
  4. Pull the lower eyelid down with your finger and hold the bottle with the other hand. Squeeze the bottle so that one drop falls into the eye (Fig. 2).
  5. Close your eyes and press the inner corner of the eye with the tip of your finger for 1-2 minutes. This prevents the drop from flowing down the tear duct into the throat, and most of the drop will remain in the eye (Fig. 3). If necessary, repeat steps 3 to 5 with the other eye.
  6. Close the bottle after use.
