hi welcome to HCM.
nausea or vomiting
is very common in any viral or bacterial fever
As u have said that nausea feeling started after u took dolomide ,it could because of that also .
dolomide has nimesulide
which is non steroidal anti inflammatory drug and can cause gastritis
which can lead to nausea like feeling and sometime vomiting also.
Since vomiting like sensation is still there you can take tablet rantac or tab pantoprazole
along with tab ondem.u will definetly get relief.
If fever still there then u can get a CBC report done from some lab to rule out any bacterial infection.
If any bacterial infection detected then u have start antibiotics for that u can visit ur family physician.
hope i had solved ur query.
