Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
In my opinion, you should definitely complete your course of antibiotics. Incomplete antibiotic courses predispose you to develop
antibiotic resistance and that makes future infections harder to treat. Hence,
1) Complete your antibiotic course, i.e. take Doxycycline for the last two days.
2) For
nausea, you could take an anti-emetic like
scopolamine or
emeset.
3) Additionally, it is likely that the antibiotics are causing these symptoms as they change the normal flora in your gastrointestinal tract.
So, you could take pro-biotics containing
Lactobacillus. Consume more yogurt than you normally do.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Pranav Balakrishnan
