I have just arrived Cameroon and yesterday, I ate a pizza for lunch. shortly after, severe stomach pains started. My driver went to pharmacy and they gave him intetrix. I take larium for malaria prevention, aspirins, omeprazol 25mg for acid reflux, and Exforge 5mg for blood pressure. Is it okay to take this medicine as prescribe 2x in morning 2x in evening for 3 days
