Ethambutol may produce decreased visual acuity which appear to be due to optic neuritis and to be related to the dose and duration of treatment. The effects are general reversible when administration of the drug is discontinued promptly. Ethambutol may produce constriction of visual field central and peripheral scotoma, and green-red colour blindness which may be associated with retrobulbar neuritis . Renal clearance of urate may be reduced in about 50%patients receiving ethambutol and acute gout has been precipitated in patients with gout or impaired renal function .
R-cinex or Rifampin is usually well tolerated but may cause GI upset. In patients with underlying chronic liver disease (e.g., alcoholics, the elderly), the drug can cause hepatitis. Rash, anemia, and thrombocytopenia are less common side effects. The most important toxicities are hepatotoxicity and peripheral neuropathy.
You should consult your doctor and adjust the doses if you get any of the side effects.
