Product introduction

Bitoma Eye Drop is suitable for adults and children and can be used by itself or in combination with other eye medicines to reduce pressure. Follow the instructions given by your doctor and use this medicine regularly to get the most benefit. If you stop using it, pressure in the eye could increase and damage your sight. Never use a bottle if the seal is broken before you use it for the first time. Make sure you remove contact lenses if you wear them and wait for at least 15 minutes before putting them back.


The most common side effects of this medicine include conjunctival hyperemia and slight redness, drooping eyelids. If you get any side effects, talk to your doctor. They may be able to tell you ways of reducing or preventing some side effects or suggest another treatment. If your vision is blurred or you have other changes in sight for a time, do not drive until your vision is clear. This is usually a short-term side effect.

Uses of Bitoma Eye Drop

Benefits of Bitoma Eye Drop

Glaucoma
Bitoma Eye Drop helps reduce pressure in your eyes (ocular hypertension) that can lead to an illness called glaucoma. It may be used alone or with other eye drops. Do not use it too often as that can make it less effective. You should only use it in the affected eye and take it regularly as prescribed by your doctor. If you stop taking it, the pressure in your eye will not be controlled. This could lead to a loss of sight.
Ocular hypertension
Bitoma Eye Drop belongs to a group of medicines called prostaglandin analogue. It is used to reduce pressure in your eyes. It increases the flow of fluid from inside the eye into the bloodstream thereby lowering the increased eye pressure. If the pressure in your eye is too high, it can damage your sight. Take it regularly as prescribed by your doctor. If you stop taking it, the pressure in your eye will not be controlled.

Side effects of Bitoma Eye Drop

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
Common side effects of Bitoma
  • Conjunctival hyperemia

How to use Bitoma Eye Drop

This medicine is for external use only. Use it in the dose and duration as advised by your doctor. Check the label for directions before use. Hold the dropper close to the eye without touching it. Gently squeeze the dropper and place the medicine inside the lower eyelid. Wipe off the extra liquid.

How Bitoma Eye Drop works

Bitoma Eye Drop is a prostaglandin analogue. It works by increasing the outflow of aqueous humor, thereby lowering the increased eye pressure.

Quick tips

  • Bitoma Eye Drop helps lower high pressure in the eye and reduces the risk of vision loss.
  • For best results, put one drop once a day in the evening/night in the affected eye(s).
  • Bitoma Eye Drop may cause brown pigmentation of the iris. This discoloration may be permanent.
  • Your eyelashes may become more dense and eyelid skin may darken. These changes should disappear after discontinuing Bitoma Eye Drop.
  • Wait for at least 5-10 minutes before delivering the next medication in the same eye to avoid dilution.
  • Apply pressure on the corner of the eye (close to the nose) for about 1 minute, immediately after instilling the drop.
