Generic Bactrim Tablet contains a combination of sulfamethoxazole and trimethoprim, two antibacterial medicines that work together against susceptible bacteria. This combination is also commonly known as co-trimoxazole or trimethoprim-sulfamethoxazole (TMP-SMX).
Generic Bactrim is used to treat certain bacterial infections when the causative organisms are susceptible to the combination. It is an antibiotic medicine, not a treatment for viral infections such as the common cold or influenza.
The exact strength, approved indications and dispensing requirements can vary by product and country.
Bactrim is a brand associated with the combination of sulfamethoxazole and trimethoprim. Generic Bactrim tablets contain the same active antibacterial combination, although manufacturers, inactive ingredients, packaging and regulatory status may differ.
A commonly recognized double-strength formulation contains sulfamethoxazole 800mg and trimethoprim 160mg.
The combination is classified as a folate-antagonist antibacterial medicine and works through sequential inhibition of bacterial folate metabolism.
Sulfamethoxazole/trimethoprim may be prescribed for certain susceptible bacterial infections, including selected:
The approved indications depend on the specific formulation and applicable local prescribing information.
A healthcare professional should determine whether Bactrim or co-trimoxazole is appropriate for an individual infection.
Generic Bactrim contains two active ingredients:
Sulfamethoxazole interferes with bacterial folate production.
Trimethoprim inhibits another step in the bacterial folate pathway.
By blocking two consecutive steps in folate metabolism, the combination can interfere with bacterial growth and reproduction.
This complementary mechanism is why the medicine is also known as trimethoprim-sulfamethoxazole (TMP-SMX) or co-trimoxazole.

Sulfamethoxazole/trimethoprim may be prescribed for certain urinary tract infections (UTIs) caused by susceptible bacteria.
The choice of antibiotic should take into account the suspected or confirmed organism, local antibiotic resistance patterns, previous antibiotic exposure and individual patient factors.
Do not use Bactrim for a UTI simply because it was effective for a previous infection. A healthcare professional should determine whether it is appropriate for the current infection.
Generic Bactrim may be used for selected bacterial respiratory infections when the responsible organism is susceptible.
It should not be used to treat viral respiratory illnesses such as:
Using antibiotics when they are not medically necessary can contribute to antibiotic resistance.
Sulfamethoxazole/trimethoprim may be prescribed for certain susceptible skin and soft-tissue infections.
The appropriate antibiotic depends on the suspected bacteria, severity of the infection and local resistance patterns. Medical evaluation is especially important for rapidly spreading redness, severe swelling, fever or significant pain.
Take Generic Bactrim exactly as prescribed by your doctor or pharmacist.
Important considerations include:
The dosage may need adjustment in people with impaired kidney function.
The appropriate dose of sulfamethoxazole/trimethoprim depends on the type and severity of infection, age, body weight, kidney function and other clinical factors.
Different formulations have different concentrations, so patients should check the exact strength printed on the packaging.
Do not use a standard internet dosage as a substitute for a prescription or professional medical advice.
Like other antibiotics, sulfamethoxazole/trimethoprim can cause side effects.
Possible adverse effects include:
Some reactions can be serious. Seek medical attention if you develop a severe rash, blistering or peeling skin, difficulty breathing, facial swelling, unusual bruising, persistent fever or other severe symptoms.
Sulfamethoxazole/trimethoprim may increase sensitivity to sunlight in some people.
While taking the medicine:
Speak with your healthcare professional if you develop an unusual or severe skin reaction.
Patients with a history of serious allergic reactions to sulfonamide medicines should tell their doctor before taking sulfamethoxazole/trimethoprim.
Stop using the medicine and seek urgent medical attention if symptoms of a serious allergic reaction occur, such as:
Sulfamethoxazole/trimethoprim is eliminated partly through the kidneys.
Patients with kidney impairment may require a different dosage or additional monitoring.
Tell your doctor if you have:
Adequate hydration may also be important during treatment, depending on your medical circumstances.
Tell your doctor or pharmacist about every medicine, vitamin and supplement you take.
Important potential interactions can involve medicines such as:
The interaction profile can be clinically significant, so professional review of your current medicines is recommended before treatment.
If you are pregnant, planning to become pregnant or breastfeeding, speak with your healthcare professional before using sulfamethoxazole/trimethoprim.
The combination may not be appropriate during certain stages of pregnancy or in particular clinical circumstances. Your doctor can assess the potential benefits and risks for your individual situation.
Antibiotic resistance occurs when bacteria become less susceptible to medicines designed to kill or inhibit them.
To help reduce unnecessary antibiotic exposure:
Bactrim, co-trimoxazole and trimethoprim-sulfamethoxazole may have different brand names, formulations, approved uses and regulatory classifications in the USA, UK and Australia.
For example, customers may encounter searches such as:
