About Theopenam SB 1000mg/500mg Injection

Theopenam SB 1000mg/500mg Injection belongs to the group of medications called anti-infectives used to treat bacterial infections. Bacterial infections are caused by the multiplication of harmful bacteria inside or on the body. These harmful bacteria produce chemicals known as toxins, which can damage tissue and make you sick. Symptoms of bacterial infection vary depending on the organ affected by bacteria.

Theopenam SB 1000mg/500mg Injection contains Meropenem and Sulbactam. Meropenem is a type of antibiotic. It works by preventing the formation of the bacterial protective covering, which is required for bacterial survival. Sulbactam is a beta-lactamase inhibitor that reduces resistance and improves Meropenem antibacterial activity.

Theopenam SB 1000mg/500mg Injection should only be administered under the supervision of a healthcare professional. The dose depends on the type of infection you have, where the infection is in the body, and how severe the infection is. Your doctor will decide on the dose that you need. The common side-effects of Theopenam SB 1000mg/500mg Injection may include injection site reactions that may occur, including swelling, pain, itching, nausea, vomiting, diarrhoea, headache, and rash. These side effects are usually mild and temporary. However, if any of these side effects persist or get worse, inform your doctor immediately.

To treat your condition effectually, continue using Theopenam SB 1000mg/500mg Injection for as long as your doctor has prescribed it. Do not use Theopenam SB 1000mg/500mg Injection without a doctor's advice if you had a skin reaction or irritation to any medicine. Consult your doctor before using Theopenam SB 1000mg/500mg Injection if you are pregnant or breastfeeding. Do not use Theopenam SB 1000mg/500mg Injection in more than prescribed doses or longer duration as it may cause adverse effects. Do not discontinue or abruptly stop the medication as it may lead to antibiotic resistance, a condition in which bacteria become resistant to antibiotics. Keep your doctor informed about your health condition and all the medicines you take before taking Theopenam SB 1000mg/500mg Injection to rule out any side effects. It is not known whether Theopenam SB 1000mg/500mg Injection can interact with alcohol or may affect your ability to drive. So, please discuss with your doctor the possible risks and benefits before taking this medicine.

Side effects of Theopenam SB 1000mg/500mg Injection
Here are the precise steps to cope with diarrhoea caused by medication usage:
  • Inform Your Doctor: Notify your doctor immediately about your diarrhoea symptoms. This allows them to adjust your medication or provide guidance on managing side effects.

  • Follow a Bland Diet: Eat easy-to-digest foods to help firm up your stool and settle your stomach. Try incorporating bananas, rice, applesauce, toast, plain crackers, and boiled vegetables into your diet.
  • Avoid Trigger Foods: Steer clear of foods that can worsen diarrhoea, such as spicy, fatty, or greasy foods, high-fibre foods, and dairy products (especially if you're lactose intolerant).
  • Practice Good Hygiene: Maintain good hygiene to prevent the spread of infection. To stay healthy, wash your hands frequently, clean and disinfect surfaces regularly, and avoid exchanging personal belongings with others.
  • Take Anti-Diarrheal Medications: If your doctor advises, anti-diarrheal medications such as loperamide might help manage diarrhoea symptoms. Always follow your doctor's directions.
  • Keep track of your diarrhoea symptoms. If they don't get better or worse or are accompanied by severe stomach pain, blood, or dehydration signs (like extreme thirst or dark urine), seek medical help.

  • If you have symptoms such as pain, swelling, redness, or warmth in your veins after taking medication, contact your doctor right once. Share information about your symptoms, medication regimen, and medical history.
  • Your doctor will then assess your medication regimen to determine if it's contributing to the thrombophlebitis. This assessment will help identify the best course of action to manage your condition and prevent further complications.
  • Your doctor may suggest certain diet and lifestyle changes to help manage your condition. This may include increasing your intake of foods rich in omega-3 fatty acids, staying hydrated, exercising regularly, and maintaining a healthy weight. Your doctor may also advise medications to reduce inflammation, prevent blood clots, or manage pain if necessary.
