Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are advised antibiotic
clindamycin for dental infection and it is appropriate antibiotic to reduce tooth related infections.
The symptoms of vomiting and vomiting along with diarrhea seems to be side effect of the antibiotic given to you and it is a common side effect of antibiotics..
For relief you can take
Pantoprazole or
Omeprazole empty stomach in the morning till you are on antibiotics..
On the other hands the symptoms of cough anad phlegm and runny nose seems to be due to upper
respiratory tract infection also known as
Common cold and it is a viral infection and you can take anti allergics like Allegra, decongestants like Pseudoephadrine,mucolytics like Ambroxol, do warm saline gargles, steam inhalations and use a humidifier in your room..
Avoid spicy and chilled foods and drink plenty of warm water..
Take soft diet..
Hope this information helps..
Thanks and regards.
