carboxymethylcellulosecost and price(10 mL)

You may not need a pharmacy for this at all.

carboxymethylcellulose sodium 5 MG/ML / glycerin 10 MG/ML / polysorbate 80 5 MG/ML Ophthalmic Solution is sold over the counter. The prices below are what pharmacies pay to dispense it on a prescription — the same active ingredient is on the shelf at a supermarket, discount store, or dollar store, usually as a store brand, for a small fraction of that. Dollar Tree, Aldi, Walmart and Costco all carry store-brand versions of common OTC medicines.

Check the strength before you switch. Prescribed strengths are often higher than what is sold on a shelf — the shelf box may be a lower dose per tablet, so you would not be taking the same thing at 10 count. Ask your pharmacist or prescriber to confirm the shelf product matches what you were prescribed.
