edit(pf) in medication names
editI have need (pf) used in multiple medication names like ondasetron hcl (pf) and morphine (pf). What does the (pf) mean? 97.82.165.112 (talk) 13:40, 1 June 2022 (UTC)
- It just means preservative free, so with no additional ingredients intended to give it an extended shelf-life. Mike Turnbull (talk) 14:17, 1 June 2022 (UTC)

- This is common for medications administered intravenously or into various body compartments, such as intrathecal or intravitreal administration, because preservatives that the body can metabolize fine when given via other routes can be toxic in such cases. --47.147.118.55 (talk) 21:14, 3 June 2022 (UTC)
