Introduction to Microtaz 4.5gm Injection

Microtaz 4.5gm injection contains two active ingredients called Piperacillin and Tazobactam, which belong to the group of medicines called broad-spectrum penicillin antibiotics and beta-lactamase inhibitors. Piperacillin with Tazobactam is used to kill many types of harmful bacteria in our body. When Piperacillin is given together with  Tazobactam, it works more effectively against certain resistant bacteria. This medicine is used to treat bacterial infections in the lower respiratory tract, urinary tract, abdomen, skin, or blood in adults and adolescents. 

Microtaz 4.5gm injection also treats bacterial infections in children aged 2-12 years, particularly abdomen infections like appendicitis, peritonitis, and gallbladder infections. Additionally, it is used in patients with low white blood cell counts. It can also be helpful for people with weaker immune systems. In some serious infections, doctors may use it along with other antibiotics to fight the germs effectively.  This medicine should not be used in children under the age of 2 years because there is not enough data available to determine its safety and effectiveness in this age group.

Do not use Microtaz 4.5gm injection if you are allergic to Piperacillin, Tazobactam,  penicillins, cephalosporins, other beta-lactamase inhibitors, or any of its ingredients. Before taking the medicine, notify your doctor if you have low potassium levels in your blood, liver, or kidney issues and undergoing hemodialysis requires monitoring. Your doctor may conduct regular blood tests during treatment. If you are taking anticoagulants or experience unexpected bleeding, inform your healthcare professional immediately. Notify your healthcare professional if you have convulsions or suspect a new or worsening infection during treatment. Additionally, be aware of haemophagocytic lymphohistiocytosis, a condition involving excessive white blood cell production, and contact your doctor immediately if you experience fever, swollen glands, weakness, lightheadedness, shortness of breath, bruising, or skin rash. Inform your doctor if you are pregnant, planning to get pregnant, or think you may be pregnant or breastfeeding.
