This is a question generally asked by patients especially the individuals of glaucoma eye drops since they are supposed to take the treatment for a lengthy time.

You are watching: How many drops are in 5 ml

How many drops a bottle will dispense relies on the viscosity that the drug and also the size of the feet in the eye dropper. It is generally embraced that the drugs which have the viscosity comparable to the of water will certainly have about 20 fall in one milliliter which way we will have actually 100 drops in 5 mL.

To confirm and also test, i took a few bottles the 5 mL eye drops and also counted how countless drops they listed individually. Castle ranged from 115 drops to 130 drops every 5 mL bottle. This walk not mean that every eye autumn of 5 mL capacity have 115 come 130 drops but we can safely i think that most of the 5 mL eye fall bottles have actually much much more than 100 drops.

There room two vital considerations here:1. Numerous eye autumn are available in volumes sufficient to last around one month. Depending on the dosage, they are obtainable in 2.5 mL, 3 mL, 5 mL and also 10 mL mostly.2. Just one fall is enough to be instilled into the eye at a time and delivers the forced dose. Any kind of amount much more than the will flow out that the eye due to the fact that the conjunctival sac (the space between the eyelids and also the eyeball) go not have room for more than one autumn generally.

In the above context, let’s take the example of a few drugs. Timolol, because that instance, is one anti-glaucoma drug supplied twice a day. For both eye (glaucoma is largely bilateral), it will be 4 fall a day and also 120 (4 x 30) fall a month. Therefore if you acquire 120 drops indigenous the 5 mL party of Timolol, it have to be enough for one month. Timolol eye autumn is obtainable mostly in 5 mL capacity.


Latanoprost/Xalatan eye fall is supplied once a work only. For both eyes, it will certainly be 2 fall a day and 60 fall a month. That is mostly easily accessible in 2.5 mL capacity.

Ketotifen eye autumn is used for allergy double a day. Because that both eyes, 4 drops will be provided in a day and 120 autumn in a month. Ketotifen is easily accessible in 5 mL and also 10 mL volumes (for one month and also two month respectively).

The over analysis argues that there are about 120 drops in a 5 mL bottle. This is reasonably supported through my tiny experiment through some eye fall bottles. This clearly is no applicable to eye fall in suspension and gel forms.
