Description of Septra Injection

Your doctor can prescribe Septra Injection (also called Bactrim) as a combination antibacterial for treating intestinal, respiratory, and middle ear or urinary tract infections. It can also be prescribed to prevent a type of pneumonia that has minimal affects on healthy individuals but can cause a serious lung infection in people with compromised immune systems. This includes those dealing with the human immunodeficiency virus (HIV) as their immune system is not able to fight off the organisms that cause Pneumocystis jiroveci pneumonia (PJP).

This medication is usually administered intravenously in a hospital or clinic setting by a doctor or other professional health worker. Once the infection is under control and you are discharged, your doctor may change you over to an oral form of Septra.

How Do the Active Ingredients work?

Septra Injection contains the active ingredients Sulfamethoxazole/Trimethoprim. Sulfamethoxazole works to interfere with the production of a folic acid derivative called dihydrofolic acid that interacts with the bacteria during their cell division. Trimethoprim follows the action of Sulfamethoxazole by preventing the production of tetrahydrofolic acid by inhibiting the actions of the coenzyme that makes it. Together, these two active ingredients interrupt two essential steps so bacteria are unable to make proteins to be able to grow and multiply.

An Antibiotic for a Fungal Pneumonia Infection?

Pneumocystis jiroveci pneumonia (PJP) is considered a life-threatening opportunistic infection that some HIV patients may come up against because their immune system is too weak to fight off a lung infection. The organism is found in our environment and is inhaled into the lungs where it fastens onto alveolar cells. This causes a decrease in oxygenation and leads to a thickening of the tissues called fibrosis. Treatment with Septra Injection is as a preventative drug that will help your body from succumbing to this infection and has had a lot of success in HIV and AIDS patients, as long as the prescribed instructions are followed.

Before You are Administered Septra Injection

Review other medical conditions and allergies you have with your doctor and list all OTC and Rx medications you currently take or use, including herbal remedies and dietary or vitamin supplements, to be certain Septra Injection is safe for you. Your doctor must be informed if you are pregnant, could become pregnant, or are breast feeding before treatment with Sulfamethoxazole/Trimethoprim as alternate treatment may be necessary to avoid risks to your unborn or nursing baby.

Precautions for Septra Injection Treatment

If you have had any allergic reaction to sulfa drugs, your doctor may change treatments as one of the active ingredients is a sulfonamide. If you are prescribed the oral formulation of Septra, keep it out of children’s reach and do not share with others. Your doctor may instruct you to take measures against becoming pregnant while undergoing treatment with Septra Injection.
