I'm taking pseudoephedrine hydrochloride and since I started taking it I have a red spot on my face about the size of a thumb print.it hasn't spread and is contained, it is in an area I previously had a pimple that I popped. I have also been shaving over the area and before that picked it a bit. This is a bad habit of mine, but never have I experienced it going red like it has and it had stared healing, the skin was thin though, so I'm wondering if this is an allergic reaction or just from me picking and shaving that has left the skin sensitive and red in the area.it has not spread and is contained in and around where the spot was. I have been taking pseudoephedrine hydrochloride for about 4 days no and other negative effects, can I continue to take it. I'm also taking gaviscon advanced oral suspension and a nasel spray.
