Why is this medication prescribed?

Infections of the bowel, lungs (pneumonia), and urinary tract are only a few of the bacterial infections that are treated with co-trimoxazole injection. Children under the age of 2 months shouldn’t take co-trimoxazole. Co-trimoxazole injection belongs to the sulfonamide drug class. It eliminates bacteria to operate.

Colds, the flu, and other viral diseases cannot be treated with antibiotics such as co-trimoxazole injection. Antibiotic use that is not necessary raises the likelihood of developing a later infection that is resistant to antibiotic treatment.

How should this medicine be used?

Co-trimoxazole injection is a solution (liquid) that needs to be combined with other liquid before being given intravenously (into a vein) over the course of 60 to 90 minutes. It is often administered every 6, 8, or 12 hours. Your infection kind and how your body responds to the medication will determine how long you need to receive therapy.

You have two options for getting co-trimoxazole injection: either in a hospital or at home. Your doctor will walk you through how to administer the drug if you will be administering co-trimoxazole injection at home. Check to see that you comprehend these instructions, and if not, consult your healthcare professional.

During the first several days of co-trimoxazole injectable therapy, you should start to feel better. Call your doctor if your symptoms don’t go away or get worse.

Even if you feel better, keep using the co-trimoxazole injection until the prescription is finished. Your infection could not be entirely treated if you stop using co-trimoxazole injection too soon or skip doses, and the bacteria might develop an antibiotic resistance.

Other uses for this medicine

Other severe bacterial infections are occasionally treated with co-trimoxazole injection. The dangers of using this drug for your illness should be discussed with your doctor.

What special precautions should I follow?

Before receiving co-trimoxazole injection,

  • If you have an allergy to sulfamethoxazole, trimethoprim, benzyl alcohol, any other sulfa medications, any other drugs, or any of the ingredients in co-trimoxazole injection, let your doctor and pharmacist know right once. Request a list of the components from your pharmacist.
  • Inform your physician and pharmacist of any additional prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are now taking or intend to use. Be certain to bring up any of the following: Amantadine (Symmetrel), angiotensin-converting-enzyme inhibitors like benazepril, and others (Lotensin), ‘blood thinners’ such as warfarin (Coumadin); cyclosporine (Gengraf, Neoral, Sandimmune); fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik); diabetic drugs used orally, digoxin (Digitek, Lanoxicaps, Lanoxin), diuretics (‘water pills’), indomethacin (Indocin), leucovorin (Fusilev), methotrexate (Rheumatrex, Trexall), phenytoin (Dilantin, Phenytek), pyrimethamine (Daraprim), and tricyclic antidepressants (mood elevator (Elavil), nortriptyline (Aventyl, Pamelor), protriptyline (Vivactil), clomipramine (Anafranil), desipramine (Norpramin), doxepin, imipramine (Tofranil), and trimipramine (Surmontil). Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects.
  • Inform your doctor if you have or have ever had megaloblastic anaemia (abnormal red blood cells caused by folate deficiency), which is caused by taking sulfonamides or trimethoprim, or thrombocytopenia (less than usual amount of platelets) (low blood levels of folic acid). Co-trimoxazole injection may not be used, according to your doctor.
  • If you have malabsorption syndrome (issues absorbing food), consume a lot of alcohol now or in the past, or take medicine to manage seizures, let your doctor know. Inform your physician if you have or have ever had asthma, low folic acid levels, severe allergies, HIV infection, glucose-6-phosphate dehydrogenase (G-6-PD) deficiency (an inherited blood disorder), phenylketonuria (PKU), porphyria (an inherited blood disease that may cause skin or nervous system problems), or problems with the thyroid, liver, or kidney.
  • Inform your physician if you are nursing a baby, intend to get pregnant, or are already pregnant. Call your doctor right away if you get pregnant while taking co-trimoxazole injectable. The foetus could suffer from co-trimoxazole.
  • Make a plan to limit your time spent in the sun and to use sunscreen, sunglasses, and protective clothes. The injection of co-trimoxazole may increase your skin’s sensitivity to sunlight.
