Topical Painkiller Ointment
The use of topical painkiller ointment or gel rather than pills for pain relief was approved just within the last few years in the US for
prescription use only.¹ Insurance records show that the average copayment for a month's supply of topical painkiller ointment for
regular users is $30. A sample of size n = 75 regular users found a sample mean copayment of $27.90.
