How purified water is dosed
From the FDA label for Pur-Wash (application NDA022305). Other purified water products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.

How long purified water keeps
No purified water label we read sets a separate limit for after opening, but they do specify how it must be stored — and the stability behind any date assumes those conditions.
Does purified water expire? The in-use limits and storage rules from its labelsWhat people report to the FDA about purified water
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 43 reports naming purified water, and the FDA flagged 77% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- depressed mood3 reports
- interstitial lung disease3 reports
- oesophagitis3 reports
- affect lability2 reports
- drug hypersensitivity2 reports
- eye irritation2 reports
- general physical health deterioration2 reports
- hepatic function abnormal2 reports
Read these as a signal, not a rate. A report does not mean purified water caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label section above.

Frequently asked questions
What is purified water?
Use For cleansing the eye to help relieve irritation or burning by removing loose foreign material
Can you take purified water with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run purified water against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What forms does purified water come in?
Across the brands we track, purified water is currently marketed as solution, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic purified water?
We do not currently list a generic-labelled purified water product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
