Apo-Sulfatrim

Name: Apo-Sulfatrim

Before Using Apo-Sulfatrim

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of sulfamethoxazole and trimethoprim combination in children 2 months of age and older. Because of the toxicity of the combination of sulfamethoxazole and trimethoprim, use in infants younger than 2 months of age is not recommended.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of sulfamethoxazole and trimethoprim combination in the elderly. However, elderly patients are more likely to have a folate deficiency, age-related kidney or liver problems, and may be more likely to experience unwanted side effects (eg, severe skin rash, increased potassium in the body, or problems with blood clotting or the immune system). There may be an adjustment in the dose for elderly patients receiving sulfamethoxazole and trimethoprim combination.

Pregnancy

Pregnancy Category Explanation
All Trimesters D Studies in pregnant women have demonstrated a risk to the fetus. However, the benefits of therapy in a life threatening situation or a serious disease, may outweigh the potential risk.

Breast Feeding

Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.

Upsides

  • Sulfamethoxazole/trimethoprim is a combination antibiotic used to treat infections such as those affecting the ear, urinary tract, lungs, or gastrointestinal tract.
  • Active against a wide range of susceptible strains of gram-positive and gram-negative bacteria, such as Streptococcus pneumoniae, Escherichia coli, Klebsiella species, Enterobacter species, Haemophilus influenzae, and others.
  • Effective concentrations of both sulfamethoxazole and trimethoprim are reached in the gastrointestinal tract, urinary tract, lungs, mouth, middle ear, and vagina. Both antibiotics also cross the placenta and are excreted in human milk.
  • Bacterial resistance is less likely to develop with the combination of sulfamethoxazole and trimethoprim than if either ingredient (sulfamethoxazole or trimethoprim) is taken alone.
  • Generic sulfamethoxazole/trimethoprim is available.

Tips

  • May be taken with or without food. Swallow tablets with a big glass of water.
  • Take only as directed by your doctor and do not share with anyone else as misuse can encourage the development of drug-resistant bacteria and reduce the effectiveness of sulfamethoxazole/trimethoprim. Sulfamethoxazole/trimethoprim will not treat viral infections, such as a cold.
  • Discontinue and seek urgent medical advice if a skin rash develops.
  • Complete the full course as prescribed (unless instructed not to do so by your doctor) to reduce the risk of resistant bacteria developing.
  • Should not be used in pregnant or lactating women or in babies less than two months old.
  • Seek urgent medical advice if an unexplained cough, shortness of breath, sore throat, fever, muscle or joint pain, paleness or yellowing of the skin, or diarrhea develop.
  • Like other antibiotics, sulfamethoxazole/trimethoprim can change the natural balance of bacteria present in your gut and may cause a severe and persistent diarrhea, associated with a bacteria called Clostridium difficile. Contact your doctor if diarrhea develops either during treatment or within a couple of months of ending treatment.
  • Keep well hydrated with fluids to avoid the development of crystals in the urine or kidney stones.
