- Children :10 – 20 mg/kgBW recommended daily dose. However, the total daily dose should not more than 600 mg.
- Elderly :Renal excretion of Rifampicin decreases with decreased kidney function, causing an increase in compensatory liver, half-life in serum of patient with young age. However, elevated levels in the blood have been reported in elderly patients on Rifampicin research, attention should be given in the use of Rifampicin against patients, particularly if proven impairment of renal function.
- Leprosy :
For the treatment of leprosy, the WHO recommends the following regimen :
- Leprosy multibaciller : Rifampicin 600 mg, once monthly under supervision + Dapsone 100 mg, once daily as swamedication + Clofazimine (Lamprene) 300 mg, once monthly under supervision + 50 mg, once daily as swamedication. Duration of the treatment at least for 2 years.

- Patients who are hypersensitive to the active substance or an additional drug substance.
- Patients with acute liver disease, jaundice or severe liver disorders.
WARNINGS AND PRECAUTIONS :
- In the long-term use, in case of serious immunological reactions that result in impaired renal function, hemolytic or thrombocytopenia, the use of Rifampicin should be immediately stopped permanently.
- On long term treatment, clinical monitoring (and liver function tests, if possible) should be done to the patient with liver disease, which showed an increased risk of further liver damage.
- Patients should be warned that treatment with Rifampicin can cause redness on the secretion of body (urine, tears, saliva, sweat, semen and sputum) and contact lenses as well as clothes can be tarnished permanently.
- Rifampicin should be used with caution in patients with a history of diabetes mellitus, because handling in patients of diabetes mellitus is more difficult. The use of Rifampicin can reduce the effectiveness of oral anti diabetic drugs (Sulphonylurea) so that, anti diabetic drug dosages need to be improved.

Recent research indicates the use of 3 times a week dose of Rifampicin 600 mg + Isoniazide 15 mg/kgBW may be more tolerable.
- Rifampicin is not recommended for intermittent therapy, patient must be informed about termination treatment with intentionally or accidentally against daily doses regimen because renal hypersensitive reactions who rarely reported.
- Rifampicin is an induction enzyme that can increase endogenous substratum metabolism including adrenaline hormone, thyroid hormone and vitamin D. Rifampicin and Isoniazide can change vitamin D metabolism. In some cases may lower the levels vitamin D 25-hidroksi and vitamin D 1,25-hidroksi followed by decreased calcium and phosphate serum and improve the parathyroid hormone.
- Laboratorium test :
The treatment of tuberculosis with Rifampicin in adults should be based on the measurement of hepatic enzymes, bilirubin, creatinine serum, complete blood count, platelet count. The test is not necessary for the children, except the complex conditions known or suspected clinically. The patient should be checked at least every month during therapy and there should be a specific question about the symptoms associated with the side effects. All patients with an abnormality must be acted upon, including laboratory tests, if necessary. Routine laboratory monitoring for toxicity in patients with normal measurement is generally not required.
- Use during pregnancy :
Rifampicin used on pregnant woman only if the benefits outweigh the risk. Use Rifampicin on the third trimester, mother and babies need to accompany by administering Vitamin K to prevent bleeding after childbirth.
- Use in lactation :
Rifampicin excreted through breast milk. However, the concentration in breast milk is very low, so that breastfeeding is not reliable for tuberculosis prophylaxis or therapy for infant breastfeeding. Not reported any adverse effects on the baby.
