Claritin-D, Pseudoephedrine, and Hair Loss

I have a follow-up question on the matter of amphetamines. Could long term use of pseudoephedrine then also cause hair loss? I know it is used in Claritin-D and that people had been using it to make illegal methamphetamines. Having taken Claritin-D for allergies over a number of years (from 18-22) and suffering from gradually thinning hair, I’d be very curious to hear your thoughts.

Many drugs can potentially cause hair loss. Before you point to a drug (such as Claritin-D) for a potential cause of hair loss, you should seek out other possible causes, such as male pattern hair loss (especially if you are losing hair in the typical pattern). There’s some interesting reading about ephedra (ephedrine and pseudoephedrine) at BodyBuilding.com, which does list hair loss as a side effect.
