Please translate these instructions. The only part I understand is 'prn'.
Directions on a prescription for naproxen 550 mg:
Sig: TQ8HX48H, then prn
Thanks for the help.
In case this is important, the RX is printed with a computer. The T before the Q is slightly lower than the Q. And the T is uppercase but is smaller than the Q, H and X letters.

Thank you so much!
I was going to get the RX filled but Target has 100 caplet bottles on sale for $5 right now. So 2 1/2 OTC pills = 1 prescription pill. The OTC ones are considerably cheaper than the RX ones, so I'll toss the RX and buy OTC. But I needed the dosing instructions for the 550 mg!!
Thank you again!

No problem. Yeah, the only
No problem. Yeah, the only difference in the rx and otc form is the salt form the naproxen is in. I don't know which salt either of them are, but the only thing the salt form does is affect the solubility of the naproxen.
Well, in fact, I think Naprosyn is naproxen base, while the otc is naproxen sodium. If this is the case, then 550mg of base would be "more" than 550mg of nap. sodium. But, this is usually a difference in a few mg, so it is not a big deal. This is not the exact ratio, just an example, but alot of times, you will see 512mg (drug) sodium is equivalent to 500mg (drug) base.
So yeah, no need for rx, when otc is alot cheaper.
Take 1 every 8 hours for 48 hours, then take as needed.
So, they want you to take the NSAID 3 times/day for the first 2 days, regardless of swelling or pain. After the first 48, take it as needed, but no more than 1 every 8 hours, not just as many as you want, wnenever you want.
