Sulfamethoxazole and trimethoprim are antibiotic medicines primarily used to treat infections caused by susceptible bacteria, such as strep throat.
Sulfamethoxazole/Trimethoxazole:
Sulfamethoxazole and trimethoprim are both used to treat bacterial infections, including middle ear infections, otitis media, peritonitis C, formula-tube infection, dental abscess, and bacterial sinus infections. Sulfamethoxazole/Trimethoxazole is also used to treat strep throat infections due to methicillin-susceptibleStaph. aureus
Note:This list of medications should not be used for the treatment of bacterial infections in the treatment of infections that are caused by susceptible bacteria.
An allergic reaction to the antibiotics may occur, leading to swelling, shock, and even death. It may also occur randomly or after prolonged treatment with other medications. Symptoms can include rash, itching, swelling, and difficulty breathing. Immediate medical attention is often required for these conditions.
Use only in appropriate medical coordination when prescribed by your health care provider.
The use of antibiotics can lead to a secondary bacterial infection, which is not caused by the same bacteria as a normal bacterial infection. When bacterial infections occur in the skin and bone, antibiotic use can enhance the sensitivity of bacteria to antibiotics. This sensitivity allows susceptible bacteria to adapt to the antibiotic, leading to its more severe or more resistant form.
Antibiotic medications are effective when administered as a 2.5 mg/day dose. Your provider may prescribe a 2.5 mg/day dose for treatment of bacterial infections in which an antibiotic is not effective. Providers regularly prescribed 2.5 mg/day for the treatment of strep throat infections in patients with infected skin and bone infections.
Use the medication regularly at evenly spaced times. To help you remember, EXPIRATION 22-24 was set as the time when antibiotics should be prescribed. To help you remember, EXPIRATION 2025 was set as the time when antibiotic medications are prescribed.
Consider taking the medication with food to reduce GI discomfort. Avoid dairy products, calcium-containing foods, and sodas to minimize stomach upset. Avoid taking potassium-containing supplements with the medication. Do not use aluminum- or magnesium-containing medications instead of aluminum and magnesium. If you have any questions about your medication use, talk to your doctor.

Use the medication in appropriate medical coordination when prescribed by your health care provider.
Your healthcare provider will determine the appropriate dosage based on your condition and medical history. It's important to follow their instructions for taking the medication and to complete the full course of treatment to ensure the infection is fully treated.
Avoid consuming alcohol while taking Sulfamethoxazole/Trimethoxazole. Alcohol can affect the effectiveness of trimethoprimazole and cause nausea, vomiting, and diarrhea. Alcohol can reduce the effectiveness of sulfamethoxazole and can affect the amount of medication your body absorbs. Additionally, alcohol can increase the risk of side effects with trimethoprim.
Avoid consuming grapefruit or grapefruit juice when using Sulfamethoxazole/Trimethoxazole. Grapefruit juice can increase the risk of side effects of Sulfamethoxazole/Trimethoxazole with the medication, such as blurred vision, increased hearing, and more frequent urination.
Consuming alcohol while taking Sulfamethoxazole/Trimethoxazole can increase the risk of side effects of trimethoprim, such as nausea, vomiting, diarrhea, and dizziness.

More about Bactrim DS tabletsBactrim DS & its generic equivalent tablets work by stopping the growth of bacteria, which cause infections. These tablets are sulfamethoxazole/trimethoprim. Sulfamethoxazole kills the bacteria by blocking the production of a hormone called a thiamin (a nutrient for the bacteria) that stops the infection from developing. Trimethoprim kills the bacteria by blocking the production of a needed hormone called a triacylglycerol (tTG) molecule. This molecule prevents bacteria from producing other essential hormones, which stops the infection from developing. Bactrim DS treats urinary tract infections (UTIs) by stopping the bacteria from producing a required hormone and stopping the bacteria from multiplying. Bactrim DS treats UTIs by stopping the bacteria from multiplying and preventing the infection from developing. If you are taking Bactrim DS for bacterial infections, consult your doctor or pharmacist for more details.
