Precautions and warnings :

Before therapy with ceftriaxone instituted, careful inquiry should be made to determine whether the patient has had previous hypersensitivity reactions to cephalosporins, penicillins or other drugs.

This product should be given cautiously to penicillin – sensitive patients. Antibiotics should be administered with caution to any patient who has demonstrated some form of allergy, particularly to drugs.

Serious acute hypersensitivity reactions may require the use of subcutaneous epinephrine and other emergency measures.

As with other cephalosporins, anaphylactic reactions with fatal outcome have been reported, even if a patient is not known to be allergic or previously exposed.

Dosage adjustments of tandak should not be necessary in patients with hepatic dysfunction ; however, in patients with both hepatic dysfunction and significant renal disease, caution should be exercised and the ceftriaxone dosage should not exceed 2 gm daily.

Alterations in prothrombin times have occurred rarely in patients treated with ceftriaxone.

Patients with impaired vitamin k synthesis or low vitamin k stores (eg, chronic hepatic disease and malnutrition) may require monitoring of prothrombin time during ceftriaxone or tandak treatment.

Vitamin k administration (10 mg weekly) may be necessary if the prothrombin time prolonged before or during therapy.

Prolonged use of tandak may result in overgrowth of nonsusceptible organisms. Careful observation of the patient is essential. If super infection occurs during therapy, appropriate measures should be taken.

Ceftriaxone should be prescribed with caution in individuals with a history of gastrointestinal disease, especially colitis.

Push Tandak slowly when administering  it. When given too fast, it can can cause severe vomiting.


Tandak (Ceftriaxone) injection is contraindicated in patients with known hypersensitivity to cephalosporin antibiotics.

In patients hypersensitive to penicillin, consider the possibility of allergic cross – reactions.

The use of sulbactam is contraindicated in individuals with a history of hypersensitivity reactions to any of the penicillins.
