Last night I got a stomach virus and threw up 30 minutes after taking my PM dose. I retook it and threw up again two hours later so I took another dose. The third time it was morning so I called my doctor only to get the secretary who said keep retaking it. I then called the pharmacy and they said all I needed was the second dose and that two hours was long enough. They also said take my morning dose as usual once I’m done yacking which I did. I’m hoping I’ll be ok, but don’t know who’s advice is right. I was also told there’s an IV form I can take in the ER, but was only told to do that if my vomiting got out of control.
