  15. Clinical Teaching • Pharmacists should advise patients that nonprescription topical analgesics are intended to treat mild to moderate pain for no longer than 7 days. • Factors that may be considered when selecting a nonprescription topical analgesic include dosage form, cost, ease of use, odor, and the patient’s medical history, including possible allergies. • Patients who are taking anticoagulation therapy should be cautioned not to use topical products that contain salicylates

  16. Clinical Teaching • Patients should be counseled on the proper use of these products, which include using them as directed and only applying topical products to intact skin. • Hands should always be washed after applying topical products and before touching the eyes or mucous membranes. • Patients should be advised to consult their primary health care provider if pain changes in severity or persists after 7 days of self-treatment.
