Any Propecia Interaction with L-Montus?

Dear doctor, I would like to know whether Propecia interacts with L-Montus.

I have been using Propecia for almost 1 year and it really did wonders to my hair. My hair texture is thickened and it covered almost all my thinning areas. Thanks for all the education you provide through this website.

I wasn’t familiar with the name L-Montus, so I researched it and found that it’s a nasal congestion medication made by Indian pharmaceutical company Fourrts. The medication is actually levocetirizine and montelukast.

Montelukast is more commonly known as Singulair, and levocetirizine is more commonly known as Xyzal. I don’t see any interaction problems for these medications with Propecia (finasteride), but double check with your prescribing physician.
