How long does a bottle of eye drops last?
At the labeled dose, roughly a month, give or take. Quell’s directions read “Apply 1 drop 3 times per day in each eye,” which is six drops a day, and a .33 fl oz (10 mL) bottle holds a couple of hundred drops, depending on the size of each one.
Why the answer is approximate
Drop size varies between products and with how firmly the bottle is squeezed, so the number of drops in a bottle isn’t fixed. Quell’s label gives the volume, .33 fl oz (10 mL), not a drop count.
Your own pace
Write the date on the carton when you open a bottle. When it runs out, you will know your real number, and that beats any estimate.
Planning orders
- One bottle: about a month at the labeled dose.
- Two bottles: about two months.
- Three bottles: about three months, and shipping is free.
