Mastertaz 1gm Injection
Description
Mastertaz injection is an antibiotic medicine used in hospitals to treat serious bacterial infections. These include infections in the respiratory tract, urinary tract, skin and soft tissue, intra-abdominal infections, septicemia, and bacterial meningitis. It is typically prescribed only when other antibiotics are ineffective.
This medicine is a combination of ceftazidime and tazobactam. Ceftazidime works by destroying the bacterial cell wall, thereby helping to stop the infection. Tazobactam supports ceftazidime by blocking substances that bacteria use to resist antibiotics, making the treatment more effective.
Some people may experience side effects like diarrhoea, nausea, headache, skin rashes, or pain at the injection site. Tell your doctor if you have allergies to antibiotics or if you have kidney issues. Also, let your doctor know about any other medicines you are taking, especially those for cancer, gout, or if you're using birth control, as they can interact with Mastertaz injection.
This medicine is administered by a doctor or nurse; never attempt to self-inject it. If you're pregnant or breastfeeding, consult your doctor first. Avoid driving if you feel dizzy or drowsy after the injection. Always store it properly and keep it out of children’s reach. If you feel unwell after receiving the medicine, such as experiencing seizures, vomiting, or persistent diarrhoea, please inform your doctor immediately.

Mode of Action
How Does It Work?
- Ceftazidime acts by inhibiting bacterial cell wall synthesis, which is essential for their survival. Therefore, it leads to the death of the cell. Hence, it helps stop the growth of bacteria and prevent infection....
- Tazobactam is a medication that enhances the effectiveness of certain antibiotics. It does this by blocking an enzyme (called beta-lactamase) made by some bacteria that can destroy antibiotics. By inhibiting this enzyme, tazobactam protects the antibiotic and enhances its ability to kill bacteria more effectively....
