The Generic name of this drug
Treatment Summary
Sulfamethoxazole is an antibiotic that works by blocking the production of folic acid in bacteria, making it harder for them to grow and reproduce. This drug is usually taken in combination with trimethoprim, which also blocks a step in bacterial folic acid production. Together, these two drugs are very effective in treating bacterial infections of the urinary, respiratory, and gastrointestinal tracts.

Effectiveness
How Septra Affects Patients
Sulfamethoxazole is an antibiotic that works by preventing bacteria from replicating. It is usually prescribed with trimethoprim, a drug that helps stop the growth of bacteria. Studies have found that taking both drugs together reduces the risk of developing a resistance than taking either one alone. Taking sulfamethoxazole may cause allergic reactions such as rashes or Stevens-Johnson syndrome, and should be stopped immediately if a rash appears. It can also contribute to folate deficiency, so it should be used with caution in those who are at a higher risk of developing a deficiency. People with glucose-6-phosph
How Septra works in the body
Sulfamethoxazole works to fight infection by stopping bacteria from producing folic acid. It does this by imitating the shape of a compound that the bacteria normally uses to make folic acid. By doing this, sulfamethoxazole blocks the bacteria's enzyme responsible for converting the compound into folic acid. This prevents the bacteria from making the folic acid it needs to make DNA and other important molecules, leading to a decrease in bacterial growth.
When to interrupt dosage
The suggested measure of Septra is contingent upon the identified disorder, for example, Urinary tract infection, Pneumocystis Jirovecii Pneumonia and Fluid replacement therapy. Dosage likewise relies upon the method of administration recorded in the table below.

Septra Toxicity & Overdose Risk
The lowest toxic dose of sulfamethoxazole in mice and rats is 2300mg/kg and 6200mg/kg, respectively. Symptoms of an overdose may include lack of appetite, stomach pain, nausea, vomiting, dizziness, headache, drowsiness, and loss of consciousness. Other signs may include fever, blood in the urine, and kidney stones. Long-term effects could include abnormal blood cells and yellowing of the skin. Treatment should be focused on managing symptoms and may include stomach pumping or inducing vomiting if necessary. Monitor the patient's lab work for evidence of blood or electrolyte imbalances.

Patient Q&A Section about septra
These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.
What is Septra used to treat?
"This medication is a combination of two antibiotics, sulfamethoxazole and trimethoprim. It can be used to treat various bacterial infections, such as those affecting the middle ear, respiratory system or intestines. It can also prevent and treat pneumonia caused by the pneumocystis virus."
Answered by AI
Is Septra and Bactrim the same?
"Sulfamethoxazole and trimethoprim are antibiotics that are used to treat bacterial infections. They are usually given together and sold under the brand names Bactrim or Septra. The combination of these antibiotics can treat a variety of infections, such as urinary tract infections (UTIs)."
Answered by AI
What type of bacteria does Septra treat?
"infections due to the bacteria Vibrio cholerae, Shigella, and Brucella; typhoid and paratyphoid fevers; infection of the intestine due to the Shigella bacteria; prevention of plague following exposure to plague; brain/spinal cord infection due to Listeria monocytogenes."
Answered by AI
Is Septra good for UTI?
"A three-day course of trimethoprim-sulfamethoxazole is recommended as empiric therapy for uncomplicated urinary tract infections in women, especially in areas where the resistance rate of Escherichia coli is less than 20 percent."
