Patients Concern
Disease/Condition Glossary
Bacterial infections: A bacterial infection is a condition in which harmful bacteria enter, multiply and infect the body. It can target any organ of the body and multiply very quickly. Many give off chemicals called toxins, which can damage tissue and make you sick. Bacterial infections vary from minor illnesses (like sore throat and ear infections) to severe brain infections (like meningitis and encephalitis). When you get infected with bacteria, you may experience generalized symptoms like fever, chills and fatigue. A few harmful bacteria that commonly cause infections include Streptococcus, Staphylococcus and E. coli. Anyone can get a bacterial infection, but people with a weak immune system or taking immunosuppressive medicines like steroids are more prone to infections.
FAQs
Ampicillin+sulbactam is used to treat bacterial infections.
Ampicillin+sulbactam contains Ampicillin and Sulbactam. Ampicillin reduces the infection by inhibiting bacterial growth. It disrupts the formation of the cell wall (outer layer), which is essential for bacteria's survival. Sulbactam inhibits the action of beta-lactamase, an enzyme produced by bacteria to destroy antibiotics (ampicillin).
You are recommended to avoid taking Ampicillin+sulbactam if you have infectious mononucleosis (viral infection with a sore throat and fever) and colitis (inflammation of the intestine), as Ampicillin+sulbactam worsens these conditions.
Ampicillin+sulbactam may decrease the effectiveness of oral contraceptives. Therefore, discuss with your doctor about other non-hormonal contraceptives such as condoms, diaphragms, etc.
No, you should not take Ampicillin+sulbactam if you have a known penicillin allergy. This medicine is a penicillin-class antibiotic and can trigger a severe allergic reaction in sensitive individuals. Talk to your doctor to find a safer alternative.
It is best to avoid alcohol while taking this medicine. While alcohol does not stop Ampicillin+sulbactam from working, it can weaken your immune system, cause dehydration, and worsen side effects like stomach upset and dizziness. Talk to your doctor if you have questions.
If you experience severe, watery, or bloody diarrhoea accompanied by stomach cramps, please contact your doctor right away for medical advice. This could be a sign of a serious antibiotic-associated bowel infection that requires prompt evaluation. Do not stop taking the antibiotic unless your doctor tells you to do so, and do not take anti-diarrhoea medicines without first speaking to your doctor.
You can take Ampicillin+sulbactam either with or without food. However, if you experience an upset stomach, nausea, or mild abdominal discomfort, taking your dose with a meal or snack can help reduce these symptoms. Talk to your doctor if stomach upset persists.
It is important to complete the full course unless your doctor advises otherwise. Stopping the antibiotic before the full course is completed can allow the strongest bacteria to survive, which can cause the infection to return and make it resistant to future treatments. If side effects make it difficult to continue treatment, please contact your doctor for advice.
This medicine should only be used during pregnancy or breastfeeding if it is clearly needed and prescribed by your healthcare provider. Some of the active ingredients can pass into breast milk in small amounts. Talk to your doctor to carefully weigh the benefits and risks for you and your baby.
Ampicillin+sulbactam is effective only against bacteria that are susceptible to it. Some bacteria, including MRSA (methicillin-resistant Staphylococcus aureus) and certain Pseudomonas species, are naturally resistant or may develop resistance to this medicine. It also does not treat viral illnesses such as colds or influenza. Your doctor may order laboratory tests to identify the bacteria causing your infection and choose the most appropriate antibiotic.
