Let's take a minute to talk about your medication. 

This is ampicillin and sulbactam. You might also hear it called by the brand name 'Unasyn'. It is a powerful type of penicillin, so you should tell your doctor if you have an allergy to penicillin. 

This antibiotic treats infections caused by bacteria. It may also help prevent infections from surgery. It does not treat infections caused by viruses, like the common cold. 

This medicine can be given as a shot or as an infusion into a vein, usually in your arm. You should watch the area where you get your dose, and tell your caregiver if you notice any tenderness, warmth or swelling. 

Patients usually tolerate this medicine well and start feeling better soon. Some common side effects can occur though, like a rash, nausea or a headache. You could also have mild diarrhea which should end when this treatment is complete. You should let your doctor know if you notice these effects or other changes to your body. When taking any antibiotic, females should watch for a vaginal yeast infection and obtain treatment if it occurs. 

As with any medicine, rare but more serious side effects can occur. This includes an allergic reaction which may start with tingling or swelling in your mouth or trouble breathing. To help keep this medicine safe for you, your doctor will follow you closely. You should tell your doctor right away if you have a bowel movement that is watery and bloody, even if it happens two or more months after your last dose. 

For best results with ampicillin and sulbactam, you should finish the full course. Otherwise, the infection could return and become hard to treat.
