Patients with excessive sleepiness, including those taking armodafinil, should be frequently reassessed for their degree of sleepiness and, if appropriate, advised to avoid driving or any other potentially dangerous activity. Patients should refrain from drinking alcohol while taking armodafinil as any drug affecting the central nervous system (CNS) may alter judgment, thinking or motor skills.
Cardiovascular Conditions and Disorders
Moderate:
armodafinil
Armodafinil has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Armodafinil may cause ECG changes, chest pain, or arrhythmia. Armodafinil should be used with caution in patients with cardiovascular complications. Armodafinil should not be used in patients with a history of left ventricular hypertrophy or in patients with mitral valve prolapse who have experienced the mitral valve prolapse syndrome when previously receiving CNS stimulants. It is recommended to monitor heart rate and blood pressure during treatment with armodafinil. Caution should be exercised when prescribing armodafinil to patients with known cardiovascular disease.
Depression
Major:
armodafinil
Armodafinil has a major potential interaction with Depression.
The use of CNS stimulants can cause psychotic symptoms, suicidal ideation, and aggression, and can exacerbate symptoms of behavior disturbance and thought disorder; CNS stimulants may induce a manic or mixed episode in patients with bipolar disorder. Psychiatric symptoms have been reported in patients with and without history of psychiatric disorders. All patients (particularly those with psychotic or bipolar disorders) should be monitored closely, especially during treatment initiation and at times of dose changes. Extreme caution should be exercised when CNS stimulants are given to patients with a history of psychosis, depression, mania, or bipolar disorder. Prior to initiating therapy, all patients should be screened for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or family history of suicide, bipolar disease, or depression). If any psychiatric symptoms emerge or are exacerbated, treatment suspension should be considered. Some CNS stimulants are contraindicated in patients with marked agitation or anxiety.
Moderate:
armodafinil
Armodafinil has a moderate potential interaction with Depression.
Armodafinil may cause adverse psychiatric reactions. Caution should be exercised when using this agent in patients with a history of psychosis, depression, or mania. If psychiatric symptoms develop in association with armodafinil administration, consider discontinuing armodafinil. Close monitoring of psychiatric symptoms is recommended.
Fluid Retention
Moderate:
nafcillin
Nafcillin has a moderate potential interaction with Fluid Retention.
Each gram of parenteral nafcillin sodium contains approximately 67 mg (2.9 mEq) of sodium and is buffered with 40 mg of sodium citrate. Each 250 mg capsule of nafcillin sodium contains approximately 17 mg (0.7 mEq) of sodium buffered with calcium carbonate. The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention. In addition, hypokalemia has been reported rarely during therapy with the penicillinase-resistant penicillins, which may be particularly important to bear in mind when treating patients with low potassium reserves or fluid and electrolyte imbalance. Clinical monitoring of electrolytes is recommended if these agents are used for prolonged periods.
Heart Failure

Liver Disease
Moderate:
armodafinil
Armodafinil has a moderate potential interaction with Liver Disease.
In a study to determine the pharmacokinetics and metabolism of armodafinil in patients with cirrhosis, the oral clearance of armodafinil was decreased by about 60%, and the steady state concentration was doubled compared to healthy patients. The dosage of armodafinil should be reduced in patients with severe hepatic impairment. Close monitoring is recommended.
Moderate:
nafcillin
Nafcillin has a moderate potential interaction with Liver Disease.
Nafcillin is primarily metabolized by the liver but also partially excreted unchanged by the kidney. The serum concentration of nafcillin may be increased and the half-life prolonged in patients with significantly impaired renal and/or hepatic function. In general, dosage adjustments are not necessary in either renal or hepatic impairment alone, but may be appropriate in patients with both renal and hepatic failure. Renal and liver function tests should be performed periodically during prolonged therapy.
Neutropenia
Major:
nafcillin
Nafcillin has a major potential interaction with Neutropenia.
The use of penicillinase-resistant penicillins has been associated with adverse hematologic effects, including neutropenia, leukopenia, granulocytopenia and thrombocytopenia, particularly when given in high parenteral dosages. Agranulocytosis and prolonged bleeding time have been reported rarely. Therapy with penicillinase-resistant penicillins should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow depression, and hematopoietic function should be monitored. Blood counts with differential should be performed prior to initiation of therapy and 1 to 3 times weekly during therapy. Hematologic abnormalities are generally reversible and resolve within several days to two weeks following discontinuation of therapy.
Noninfectious Colitis
Major:
nafcillin
Nafcillin 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.
Psychosis
