Interactions between Isoniazid and Minolira

Isoniazid has a major potential interaction with Alcoholism.

The use of isoniazid is contraindicated in patients with a history of hepatic injury due to this drug and acute liver disease of any etiology. Caution is advised when using the drug in patients with chronic liver disease or a history of alcoholism. This drug has been associated with severe and sometimes fatal hepatitis, which may occur even after many months of therapy. In a US Public Health Service Surveillance Study of 13,838 persons taking isoniazid, there were 8 deaths among 174 cases of hepatitis. Epidemiologic studies indicate an increased incidence with increasing age, alcohol use, and female gender. As a precautionary measure, routine monitoring of serum transaminases (SGOT, SGPT) and bilirubin may be considered, although a transient and harmless increase in serum transaminase reportedly occurs in 10% to 20% of patients, usually in the first 3 months of therapy. Patients should be advised to promptly discontinue isoniazid therapy and seek medical attention if they experience signs or symptoms suggestive of liver damage such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice. Reinstitution of the drug should occur only after symptoms and laboratory abnormalities resolve, with low and gradually increasing dosages.

Isoniazid has a major potential interaction with Alcoholism.

Isoniazid commonly causes dose-related peripheral neuropathy, which results from the depletion of pyridoxine in the presence of the drug. The neuropathy is usually preceded by paraesthesia's of the feet and hands. Therapy with isoniazid should be administered cautiously in patients with pre-existing peripheral neuropathy or risk factors for developing the condition, such as malnutrition, diabetes and alcoholism. Careful monitoring is recommended on these patients. Pyridoxine (vitamin B6) at a dosage of 10 to 50 mg/day may prevent or attenuate isoniazid-related peripheral neuropathy and is recommended for these patients.

Isoniazid has a major potential interaction with Diabetes Mellitus.

Isoniazid commonly causes dose-related peripheral neuropathy, which results from the depletion of pyridoxine in the presence of the drug. The neuropathy is usually preceded by paraesthesia's of the feet and hands. Therapy with isoniazid should be administered cautiously in patients with pre-existing peripheral neuropathy or risk factors for developing the condition, such as malnutrition, diabetes and alcoholism. Careful monitoring is recommended on these patients. Pyridoxine (vitamin B6) at a dosage of 10 to 50 mg/day may prevent or attenuate isoniazid-related peripheral neuropathy and is recommended for these patients.

The minocycline in Minolira has a moderate potential interaction with Esophageal Obstruction.

The use of oral tetracycline capsules and tablets has been associated with esophageal irritation and ulceration in patients who ingested the drug without sufficient fluid shortly before bedtime. Therapy with solid formulations of tetracyclines should preferably be avoided in patients with esophageal obstruction, compression or dyskinesia. If the drugs are used, patients should be advised not to take the medication just before retiring and to drink fluids liberally.

Isoniazid has a moderate potential interaction with Hemodialysis.

Isoniazid is substantially removed by hemodialysis and should be administered after dialysis.

Isoniazid has a moderate potential interaction with HIV-1 Infection.

Caution and close monitoring is advised when using isoniazid in patients with HIV seropositive patients. Patients with pulmonary tuberculosis and HIV infection may have problems with malabsorption. Screening of antimycobacterial drug levels, especially in patients with advanced HIV disease, may be necessary to prevent the emergence of multi-drug resistant tuberculosis.

Isoniazid has a major potential interaction with Liver Disease.

The use of isoniazid is contraindicated in patients with a history of hepatic injury due to this drug and acute liver disease of any etiology. Caution is advised when using the drug in patients with chronic liver disease or a history of alcoholism. This drug has been associated with severe and sometimes fatal hepatitis, which may occur even after many months of therapy. In a US Public Health Service Surveillance Study of 13,838 persons taking isoniazid, there were 8 deaths among 174 cases of hepatitis. Epidemiologic studies indicate an increased incidence with increasing age, alcohol use, and female gender. As a precautionary measure, routine monitoring of serum transaminases (SGOT, SGPT) and bilirubin may be considered, although a transient and harmless increase in serum transaminase reportedly occurs in 10% to 20% of patients, usually in the first 3 months of therapy. Patients should be advised to promptly discontinue isoniazid therapy and seek medical attention if they experience signs or symptoms suggestive of liver damage such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice. Reinstitution of the drug should occur only after symptoms and laboratory abnormalities resolve, with low and gradually increasing dosages.

The minocycline in Minolira has a moderate potential interaction with Liver Disease.

The use of tetracyclines has rarely been associated with hepatotoxicity. Histologic fatty changes of the liver, elevated liver enzymes, and jaundice have been reported, primarily in patients treated with large doses of intravenous tetracycline hydrochloride (no longer available in the U.S.) but also in patients receiving high oral doses of these drugs. Therapy with tetracyclines should be administered cautiously in patients with preexisting liver disease or biliary obstruction. Reduced dosages may be appropriate, particularly with minocycline and doxycycline, since the former is metabolized by the liver and the latter undergoes enterohepatic recycling. Liver function tests are recommended prior to and during therapy, and the concomitant use of other potentially hepatotoxic drugs should be avoided.

Isoniazid has a major potential interaction with Malnourishment.

Isoniazid commonly causes dose-related peripheral neuropathy, which results from the depletion of pyridoxine in the presence of the drug. The neuropathy is usually preceded by paraesthesia's of the feet and hands. Therapy with isoniazid should be administered cautiously in patients with pre-existing peripheral neuropathy or risk factors for developing the condition, such as malnutrition, diabetes and alcoholism. Careful monitoring is recommended on these patients. Pyridoxine (vitamin B6) at a dosage of 10 to 50 mg/day may prevent or attenuate isoniazid-related peripheral neuropathy and is recommended for these patients.

The minocycline in Minolira has a major potential interaction with Noninfectious Colitis.

Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.

Isoniazid has a major potential interaction with Peripheral Neuropathy.

Isoniazid commonly causes dose-related peripheral neuropathy, which results from the depletion of pyridoxine in the presence of the drug. The neuropathy is usually preceded by paraesthesia's of the feet and hands. Therapy with isoniazid should be administered cautiously in patients with pre-existing peripheral neuropathy or risk factors for developing the condition, such as malnutrition, diabetes and alcoholism. Careful monitoring is recommended on these patients. Pyridoxine (vitamin B6) at a dosage of 10 to 50 mg/day may prevent or attenuate isoniazid-related peripheral neuropathy and is recommended for these patients.

Isoniazid has a moderate potential interaction with Renal Dysfunction.

Isoniazid may cause cerebellar syndrome in patients with chronic kidney disease. Patients with end-stage renal disease have been reported to have an increased risk of developing tuberculosis. Careful monitoring is recommended if this drug is used in patients with severe renal dysfunction. Dosage adjustments in renal impairment are generally not necessary except in slow acetylators with a creatinine clearance below 10 mL/min. Approximately 50% of Blacks and Caucasians are slow acetylators, and most Eskimos and Asians are rapid acetylators.

The minocycline in Minolira has a moderate potential interaction with Renal Dysfunction.

Tetracyclines (except doxycycline) are eliminated by the kidney to various extent. Patients with renal impairment may be at greater risk for tetracycline-associated hepatic and/or renal toxicity (increased BUN with consequent azotemia, hyperphosphatemia, and acidosis) due to decreased drug clearance. Therapy with tetracyclines should be administered cautiously at reduced dosages in patients with renal impairment. Clinical monitoring of renal and liver function is recommended, and serum tetracycline levels may be necessary during prolonged therapy.
