Can you take Eplerenone with Myrac?

The minocycline in Myrac 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.

Eplerenone has a major potential interaction with Hyperkalemia.

The use of eplerenone is contraindicated in the presence of elevated serum potassium concentrations (> 5.5 mEq/L). Eplerenone is a blocker of aldosterone binding at the mineralocorticoid receptor and can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias. Careful monitoring of serum potassium levels is necessary in patients who are at risk for the development of hyperkalemia (including those receiving concomitant ACE inhibitors or angiotensin II receptor antagonists), especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function. In clinical trials, monitoring occurred every 2 weeks for the first 1 to 2 months, then monthly thereafter. Eplerenone should be withdrawn immediately if hyperkalemia develops, and measures should be initiated to lower serum potassium if it exceeds 6.5 mEq/L.

Eplerenone has a moderate potential interaction with Liver Disease.

Eplerenone is primarily metabolized by the liver. In patients with moderate (Child-Pugh Class B) hepatic impairment given eplerenone 400 mg, the steady-state peak plasma concentration (Cmax) and systemic exposure (AUC) of eplerenone were increased by 3.6% and 42%, respectively, compared to those in normal subjects. In 16 patients with mild to moderate hepatic impairment who received 400 mg of eplerenone, no elevations in serum potassium above 5.5 mmol/L were observed. Their mean increase in serum potassium was 0.12 mEq/L compared to 0.13 mEq/L in normal controls. No adjustment of the starting dosage is recommended for patients with mild to moderate hepatic impairment. The use of eplerenone in patients with severe hepatic impairment has not been evaluated, thus caution is advised.

The minocycline in Myrac 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.

The minocycline in Myrac 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.

Eplerenone has a major potential interaction with Renal Dysfunction.

The use of eplerenone is contraindicated in patients with renal impairment as defined by serum creatinine above 2.0 mg/dL for males or 1.8 mg/dL for females, or a creatinine clearance (CrCl) below 50 mL/min. These patients are at increased risk of developing persistent hyperkalemia, which is the principal adverse effect of eplerenone and can lead to potentially life-threatening cardiac arrhythmias. The incidence of hyperkalemia increases with decreasing renal function. In clinical studies of eplerenone, serum potassium levels exceeding 5.5 mEq/L were observed in 10.4% of treated patients with baseline calculated CrCl less than 70 mL/min, 5.6% of patients with baseline CrCl 70 to 100 mL/min, and 2.6% of patients with baseline CrCl greater than 100 mL/min. Careful monitoring of serum potassium levels is necessary in patients treated with eplerenone who are at risk for the development of hyperkalemia, especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function. In clinical trials, monitoring occurred every 2 weeks for the first 1 to 2 months, then monthly thereafter. Eplerenone should be withdrawn immediately if hyperkalemia develops, and measures should be initiated to lower serum potassium if it exceeds 6.5 mEq/L.

The minocycline in Myrac 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.

Eplerenone has a major potential interaction with Type 2 Diabetes.

The use of eplerenone is contraindicated in patients with type II diabetes mellitus and microalbuminuria. These patients are at increased risk of developing persistent hyperkalemia, which is the principal adverse effect of eplerenone and can lead to potentially life-threatening cardiac arrhythmias. In a study of such patients treated with a 200 mg/day dose, the frequency of maximum serum potassium levels exceeding 5.5 mEq/L was 33% with eplerenone alone and 38% in combination with enalapril. In other patient populations, the frequency has been reported at 1% for the 200 mg/day dose and 8.7% for the 400 mg/day dose. Careful monitoring of serum potassium levels is necessary in patients treated with eplerenone who are at risk for the development of hyperkalemia, especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function. In clinical trials, monitoring occurred every 2 weeks for the first 1 to 2 months, then monthly thereafter. Eplerenone should be withdrawn immediately if hyperkalemia develops, and measures should be initiated to lower serum potassium if it exceeds 6.5 mEq/L.
