Jewelfields, here's my additional $0.02. Please consider the information offered by potatoboy99, and take his advice!

You state: "I am not familiar with pain meds...."

A number of additional reasons exist for NOT medicating yourself, family, or anyone with strong pain meds because he/she has suffered an accident or trauma unless you are a trained medical professional, i.e., MD, RN, LVN, EMT, etc.

Firstly, the person may be allergic to the substance. My cousin was prescribed Tylenol with codeine by her physician for a bad wrist sprain. (This happened back in the 70's.) She had never taken codeine before, and neither she nor her doctor had any idea she might be allergic. She had an accute allergic reaction--hives and difficulty breathing--shortly after taking her first tablet. She was terrified! She had to be treated with some kind of injection that's used to treat severe allergic reactions.

Also, drug interactions must be considered. Some pain killers can cause very serious reactions when given to someone who is already taking other prescribed medications. (Did you ever see the "Law and Order" episode where an alcoholic (drunk-at-the-time) doctor prescribed Demerol to a young lady admitted to the ER without noting that she was already taking a certain antidepressant? She died as a result of this combination.)

Finally, even if there are no allergy or drug interaction considerations, strong pain meds--by themselves--can cause serious problems for a person who has suffered a head injury or has some undiagnosed abdominal problem.

Please stay with Advil or Tylenol or Naproxyn or something else recommended by a pharmacist.
