How many eyedrops are there in a 10 ml bottle of Cosopt?

Question

My Kaiser pharmacy insists that 2 bottles should last me 100 days but I run out way before that time when I am using 4 drops per day. In the past other pharmacies have given me 3 10-ml bottles for 100 days. So, how many drops are actually in a 10-ml bottle?

Answer 1

20 drops per ml is the accepted equivalence.

HOWEVER......every medication is different depending on the viscosity, surface tension, temperature, diameter of the dropper, etc.

In my calculations I've always used 15 drops per ml. Not because of some reference book, but years and years of doing this.

Answer 3

10 Ml Bottle

Answer 4

There are about 20 drops per ml, so multiply that by 10 and there should have been 200 drops. So it should only last you 100 days, given no wasting of it at all - impossible with drops. Or, it could have been that was all your physician wrote for. Either way, if you need more medicine, you may have to call to get a new prescription to get it.

There are 75gtts (gtts.=drops) in a teaspoon. One teaspoon= 5ml. There are an approximate equilavent of 150gtts in a 10ml bottle.
