Hello. I've been struggling with acne for some time now. My GP prescribed me Lymecycline which i continue to take. It's been 5 weeks now and i can't see much of a difference but I won't see my GP now because he told me to take it for 3 months. I also use Freederm but it says that it's not recommended to take Lymecycline and other medications containing aluminium. Is it possible that freederm might decrease the effectivness of lymecycline as it contains some aluminium? It also says that it takes about 8 weeks to see a difference when using lymecycline.
