Anti Allergy Meds Breastfeeding

Hello mga momshies, sino po dito naka try uminom ng antihistamines for allergic rhinitis po? Have you tried STELIX Brand (Montelukast Levoceterizine) po? Is it okay po ba sa nagbebreastfeed? Is there any adverse effect sa baby or sa milk supply? Forgot to ask my doctor kasi if its safe for breastfeeding. Im currently taking it for my allergic rhinitis. TY.
