    Allergic to which one? Priolosec or Omnicef
    josh8587 posted:
    Unfortunately, I was taking two medications for about the same amount of time at the same time. After about four days to a week I began breaking out with hives and had weak arm muscles. After stopping both medications the complications stopped about 2 days later.

    I'm assuming I was allergic to one of the two medications: Omnicef or Prilosec. They are two very different medications, so I was hoping someone more knowledgeable than myself on the subject could speculate which one I am allergic to.

    Thanks an advance for any help or advice you can give.

    Hiya and welcome,

    I'm afraid anything would be a guess here.
    Best to follow up and talk to the doctor about this.
