On the leaflets of some medications including my minoxidil, it says this is not all the infomation available ask you doctor for a more detailed description, and ask your doctor for a full list of side effects.
Now while doctors are very suspect when it comes to trickery on there patients, I dont think they would hide a side effects list especially if you wernt on the medication, so I would sugest you goto a dermo, say your NOT on rogaine because you are on something that you cant use with it and ask for the full list if there even is one.
