medication my friend gave me for my headache

I had a headache and asked my friend for some asprin.  My wife had never seen this
medicine and so she looked it up online.  Come to find out it was a medicine called
Casodex.  I only took one, but am wondering if I should be worried about it because
it's not a medication that's prescribed to me?  My friend had given it to me in an Advil bottle.  What should I do. Thanks.

Casodex is not for headaches. As a general rule of thumb, DO NOT take medicines prescribed for another person or give yours to someone else. With that out of they way here is what I can tell you. You only took one and if you did not experience chest pain, flu like symptoms or trouble breathing then you did not have an adverse reaction to this medication. You are not on any medication currently , therefore it would not have affected any other medication level in your system. I would advise not to take any more of them. In the future if you require medication for a headache and a friend gives you a tablet you are not familiar with you can always call 1-800-222-1222 which is the poison control line. You can give them the tablet ID and they will be able to tell you what medication you have in your hand.

Casodex is given for the treatment of prostate cancer!  Why in the world would they give you this for a headache.  You should tell your friend.  She may not know she has it in her advil bottle and it could hurt her/him.
