It is okay to take the medication as prescribed. It is to prevent infection in case of breach or contamination of the blood during surgery.

That is the typical dose prescribed for prophylaxis prior to dental procedures. It is meant to protect from a prosthetic joint infection as germs can cause a transient bacteremia during invasive dental procedures.
