medicine interfering with milk supply

Jessica
Anyone else have Vertigo? I was diagnosed with it 2 days ago. I was given a medication called Meclizine. I've only taken two pills & it has pretty much stopped my milk supply! Are there any alternatives to treating vertigo? Since my milk supply has drastically decreased does that mean my milk is gone forever? If I discontinue the meds, will I start to produce more milk? Any tips will be greatly appreciated.
