My doctor diagnosed me with shingles on Friday,7/31/2015. He gave me Diclofenac in pillform,75mg,2x,daily. Yesterday I felt good. But woke up very nauseated and felt quite sickly.I take Lisinipril -10/12.5mg,Carvedilol-6.5mg, Citalopram-20mg &the diclofenac . I just wish I could vomit because of the nausea. Dr. Rachjaibun gave me the diclofenac to control the pain,which I am thankful for. However the nausea is to the point I can hardly cope with it.So I took 25 mg of Promethazine about an hour ago. Is that ok? My doctor is on vacation and I can t afford a $6000 trip to the ER. And by the way I have had the shingles Vaccine several years agoo because I m a 1st. Grade teacher and my students were falling like flies. I got the shingles anyway.
