I Have Been Taking Zontivity For A Month And Want

I have been taking Zontivity for a month and want to know if it is safe to quit taking it? It is difficult to find a pharmacy that carries Zontivity and it is very expensive. I had a heart attack in October and I am on Plavix, Zontivity, aspirin, Avoristatin, Lasiniprol and Carvadol. (not sure about spellings) Nevin Thompson
