The choice between the two depends more on individual factors like other health conditions and treatment goals rather than concerns about addiction.

Both Headache Relief PM and Biofreeze are relatively easy to use, with each drug offering straightforward dosing regimens. While Headache Relief PM may be simpler with a once-daily schedule, Biofreeze’s flexibility in dosage forms allows for personalization.
