The most common dosage for the typical bacterial sinus infection is 500 mg of amoxicillin, three to four times a day according to www.drugs.com.
Antibiotics may be needed when symptoms of sinusitis do not respond to home treatment, symptoms are severe, or complications (such as pus forming in sinus cavities) develop. 1  Amoxicillin is often the first choice in treating sinusitis because it is usually effective and has few side effects. It should not be used if you are allergic to amoxicillin or have been diagnosed with mononucleosis. Trimethoprim-sulfamethoxazole may be prescribed for people who are allergic to amoxicillin.
