A patient can use a medicating cream as desired. What does this prescription most likely indicate?

“Ad lib” means “as desired” or “at one’s discretion.” Therefore, a prescription allowing the patient to use the medicating cream as desired most likely indicates ad lib. The other choices mean as tolerated (as tol), twice daily (b.i.d.), and three times daily (t.i.d.).
