Bactrim (generic name: sulfamethoxazole/trimethoprim) is a prescription drug used to treat a variety of bacterial infections, such as urinary tract infections (UTIs), respiratory tract infections (Pneumonia) and sexually transmitted infections (STIs). Bactrim is available in the form of tablets and also in the form of a liquid suspension that can be mixed with food or water to form a suspension. The liquid suspension form of Bactrim is easy to use and can be administered directly into the mouth or injected into the vein of the penis or injected under the skin. This prescription medication is most often used for the treatment of:
Bactrim works by blocking a protein called guanylate cyclase, which is involved in the production of nitric oxide, a chemical that regulates the activity of the enzyme guanosine diphosphate (GDP). This enzyme is crucial for the normal functioning of the body’s blood vessels. Bactrim inhibits the production of this chemical, leading to an increased level of guanosine diphosphate (GDP) in the body, which is essential for the infection to be passed through.
This chemical is also involved in the breakdown of the DNA, which is necessary for the replication and repair of bacteria. When Bactrim is taken orally, it can cause nausea, vomiting and diarrhoea. The nausea and diarrhoea are usually mild and temporary, resolving as the body adjusts to the medication. If they persist, it is important to discuss the side effects with a doctor. However, if they worsen, it is advisable to stop the medication and seek medical attention.
It is important to note that Bactrim is available only with a prescription and can not be used without one. In Canada, the dosage of Bactrim can be obtained from your physician, and you can ask for it at a participating pharmacy or at a local drugstore.
Bactrim is only available in a capsule form, and it should not be taken by pregnant women, children younger than 8 years old and anyone who has liver or kidney disease.
Take Bactrim as directed by your doctor. Swallow the tablet whole with a full glass of water. Do not crush or break the tablet. If it is broken, the medication will not be effective in preventing infections. If it is broken or if symptoms persist, the medication may be stopped and your doctor may recommend a different treatment. You can also ask your doctor about alternative treatments.
Bactrim can be taken with or without food. However, if you have consumed a high-fat meal before taking Bactrim, you may experience side effects such as nausea, vomiting, diarrhoea and headache. These may be mild and temporary, resolving as the body adjusts to the medication.
