Ganfort eye drops contain two active substances:
- Bimatoprost - prostaglandin analogue
- Timolol - beta blocker
The eyes contain a clear fluid that nourishes the eye, and this fluid is continuously removed from the eye and replaced with a new one. If the clear fluid is removed from the eye too quickly or if an eye makes new fluid too quickly, it leads to the accumulation of fluid in the eye and to increased eye pressure which can damage your vision.
Ganfort eye drops accelerate the drainage of fluid from the eye and reduce the creation of new fluid, thus reducing the intraocular pressure.
Because of this effect, it is used in the treatment of open angle glaucoma.
What you need to know before you start applying Ganfort eye drops
Considering that it contains timolol - a beta blocker, in rare situations this substance can be absorbed through the mucous membranes of the eye into the bloodstream which can have an impact on the heart function. In healthy subjects, this effect is negligible, but patients who already have heart disease may experience a worsening of symptoms and therefore these patients should not apply Ganfort eye drops.
For the same reasons, absorbed timolol may cause a worsening of symptoms in asthmatics.
This medicine should be used cautiously in the following conditions:
- Impaired blood circulation
- Diabetes (these eye drops may mask the symptoms of hypoglycemia)
- Edema of the retina
If you are planning a surgery, you need to inform your doctor that you are using these eye drops as they can influence the effect of certain anesthetics.
Ganfort may turn your eyelashes black and make them grow longer, which is especially noticeable if you treat only one eye.
It should not be used in children younger than 18 years.
Ganfort eye drops, pregnancy and breastfeeding
It should not be used during pregnancy due to insufficient data on its safety during pregnancy.
Given that timolol is excreted into breast milk, you should not breastfeed while on treatment with this medicine.
How to use

Pull the lower lid, throw your head back and then drip one drop in an eye. Than close the eye and hold it closed for a couple of minutes.
Do not touch the eye with a dropper because it can cause infection.
