Brompheniramine-Phenylephrine (Generic for Rynex PE)
by: David

"1/4 to 1/2 tsp..." = 1.25ml to 2.5ml
"...po q4-6h..." = by mouth every 4-6 hours
"...prn" = as needed

6oz = 180ml (6oz X 30ml/oz)

So lets do the math...

and put it all together:

1.25 to 2.5ml every 4-6 hours as needed

...so the patient could take, as written, at the most... 2.5ml every 4 hours... 2.5ml X 6 doses in one day = 15ml/day

180ml divided by 15ml/day = 12 days

So, therefore, the days supply is 12 days.

Oh, and the dispensed quantity was listed as 6oz or 180ml.

Thank you for the question!
