Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
I have gone through the details given. With a comparatively high dose of Ibuprofen there is a possibility of getting severe gastritis, nausea, and vomiting. Because being a NSAID, it can reduce protection to stomach
mucous membrane leading to excess acid and gastritis, which can cause nausea and vomiting and even burning sensation in epigastric region and at the back of the throat.
Dizziness can also be felt. Therefore, it better to avoid taking the drug on an empty stomach. Or take it after taking a drug like
Ranitidine or
Omeprazole. Further to reduce your present symptoms you may take a
Domperidone plus Omeprazole tablet. Take plenty of fluids and rest for a few hours. Do not repeat Ibuprofen in high dose. If required then take it as mentioned above.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Prabhakar Laxman Jathar
