Clinical Particulars and Indications

SEPTRIN is indicated for the treatment of various bacterial infections.

Here are some of the common clinical indications for SEPTRIN:

Urinary Tract Infections

  • Treatment of acute uncomplicated urinary tract infections.
  • Initial episodes of uncomplicated urinary tract infections are often treated with a single effective antibacterial agent instead of a combination.

Respiratory Tract Infections

  • Treatment of otitis media.
  • SEPTRIN is not indicated for prophylactic or prolonged administration in otitis media.
  • Treatment of acute exacerbations of chronic bronchitis.
  • Treatment and prevention of Pneumocystis jiroveci (P. carinii) pneumonitis.

Genital Tract Infections

  • Treatment of gonorrhea, including oro-pharyngeal and ano-rectal infection.
  • Treatment of chancroid.
  • Treatment of granuloma inguinale.

Gastrointestinal Tract Infections

  • Treatment of cholera, as an adjunct to fluid and electrolyte replacement when the organism is sensitive in vitro.
  • Treatment of shigellosis.
  • Treatment of travelers’ diarrhea, including gastroenteritis due to enterotoxigenic E. coli.

Other Bacterial Infections

  • SEPTRIN may be useful in the treatment of nocardiosis, toxoplasmosis, brucellosis (as second-line therapy in combination with gentamicin or rifampicin), and melioidosis (in combination with ceftazidime or cefoperazone/sulbactam).

Please note that the local situation and bacterial susceptibility should always be considered when selecting antibiotic therapy.

Dosage and Administration

The dosage of SEPTRIN varies depending on the age group and the specific condition being treated. It is important to follow the prescribed dosage instructions provided by the physician or healthcare professional. Here’s a general overview of the recommended dosages:

Acute Infections (Adults and Children over 12 years):

  • Tablets/Capsules (Standard Dosage):
    • 2 tablets every 12 hours
    • 1 tablet every 12 hours for double-strength tablets
    • 10 ml every 12 hours for adult suspension

Acute Infections (Children aged 12 years and under):

  • Paediatric Tablets:
    • 4 tablets every 12 hours for ages 6 to 12 years
    • 2 tablets every 12 hours for ages 6 months to 5 years
    • 2.5 ml every 12 hours for ages 6 weeks to 5 months

The duration of treatment may vary depending on the condition being treated. It is important to continue treatment until the patient has been symptom-free for at least two days, with the majority requiring treatment for at least 5 days. If there is no improvement after 7 days of therapy, reassessment by a healthcare professional is recommended.

Precautions and Potential Adverse Reactions

While SEPTRIN is generally well-tolerated, there are certain precautions and potential adverse reactions that should be considered. Here are some important points to keep in mind:

  • SEPTRIN should not be given to patients with a history of hypersensitivity to sulphonamides, trimethoprim, co-trimoxazole, or any excipients of SEPTRIN.
  • It should be used with caution in elderly patients and those with impaired kidney and/or liver function, as they may be more susceptible to adverse reactions.
  • Regular monitoring of blood counts, especially for folate-deficient patients or those receiving long-term high-dose SEPTRIN, is advisable.
  • SEPTRIN should be used with caution in patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency, as hemolysis may occur.
  • Patients with severe allergy or bronchial asthma should be given SEPTRIN with caution.
  • It should not be used in the treatment of streptococcal pharyngitis caused by Group A beta-hemolytic streptococci.
  • SEPTRIN may interact with other medications, such as diuretics, zidovudine, warfarin, phenytoin, and sulfonylurea hypoglycemic agents. Close monitoring is advised in such cases.

Adverse reactions to SEPTRIN can occur, although they are generally rare. Some possible adverse reactions include nausea, diarrhea, skin rashes, hypersensitivity reactions (e.g., Stevens-Johnson syndrome), blood disorders, and hepatic or renal impairment. If any adverse reactions are observed, it is important to discontinue the medication and seek medical attention.
