How Does It Work?

Interactions with other medicines

• Rifampicin is a potent inducer of a particular enzyme system that is involved in metabolising many medications. Concurrent use will hence decrease the efficacy of the other medicines.
• Use of the following medicinal products concomitantly with Trac 4 is not recommended: nevirapine, simvastatin, oral contraceptives, and ritonavir
• Antacids reduce the amount of rifampicin, isoniazid and ethambutol that is absorbed from the gut to the bloodstream. To avoid this, Trac 4 should be taken at least 1 hour before antacids.
• Corticosteroids can reduce the plasma levels of isoniazid by increasing its metabolic and excretion.
• Plasma concentrations of morphine may be reduced by rifampicin. The analgesic effect of morphine should be monitored, and doses of morphine adjusted during and after treatment with rifampicin.
• Rifampicin may reduce the effectiveness of oral contraceptives, and Pyrazinamide decreases the contraceptive effect of oestrogens. Patients treated with Trac 4 should use a non-hormonal method of contraception.
• Oral typhoid vaccine might be inactivated by concomitant antibiotic administration.
• This medication decreases the effect of medicines used to treat gout, such as probenecid and sulfinpyrazone, which are uricosuric agents (increase the excretion of uric acid from the body).

Interactions with food items

• This medication is recommended to be taken 30 mins before food or 2 hours after food.
• Food items that are rich in tyramine, such as cured meat, some cheeses (e.g., matured cheeses), wine, beer and some fish (e.g., tuna, mackerel, salmon), should be avoided.
• This is because Isoniazid can decrease the metabolism of tyramine and histamine, resulting in side effects like headache, sweating, flushing, heart palpitations, and fall in blood pressure.
