Drug interactions

Moderate drug interactions

Moderate:

armodafinil silodosin

Applies to: armodafinil and silodosin

Armodafinil may reduce the blood levels of silodosin, which may make the medication less effective in some cases.

Contact your doctor if your symptoms worsen or your condition changes.

Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

silodosin Food/Lifestyle

Applies to: silodosin

Taking silodosin with food can reduce the risk and/or severity of side effects. Therefore, silodosin should be administered with or immediately after a meal.

Minor food/lifestyle interactions

Disease interactions

14 potential interactions Applies to: 11 conditions, including Depression, Hypotension, Psychosis, Syncope, and Cataract.

Alcoholism

Moderate:

armodafinil

Armodafinil has a moderate potential interaction with Alcoholism.

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.

Cataract

Moderate:

silodosin

Silodosin has a moderate potential interaction with Cataract.

Intraoperative Floppy Iris Syndrome has been observed during cataract surgery in some patients on or previously treated with antiadrenergic agents. If a patient is undergoing cataract surgery, the ophthalmologist should be prepared for possible modifications of the surgical technique (iris hooks, iris dilator rings). There does not appear to be a benefit in stopping antiadrenergic agents therapy prior to the cataracts surgery.

Dehydration

Moderate:

silodosin

Silodosin has a moderate potential interaction with Dehydration.

Peripheral alpha 1- adrenergic receptor blocking agents (aka alpha 1- blockers) cause vasodilation and can produce marked hypotension, especially orthostatic hypotension with syncope or other postural symptoms such as dizziness, lightheadedness, and palpitations. Orthostatic effects are most common during initiation of therapy and often occur within 90 minutes after the first dose. However, they can also occur following a dosage increase or resumption of therapy after an interruption of more than a few days. Agents with alpha 1a specificity, such as tamsulosin, act primarily on the prostate but are not devoid of hypotensive effects. Therapy with peripheral alpha-1 blockers should be administered cautiously in patients with or predisposed to hypotensive or syncopal episodes. Caution is also advised in patients who are dehydrated (e.g., due to severe or prolonged diarrhea or vomiting), since they may be more sensitive to the hypotensive effect of the drugs. Therapy should be initiated with the lowest dosage possible and titrated gradually based on patient response and tolerance in accordance with the individual product package labeling. During initiation or reinstitution of therapy and following an increase in dosage, patients should be advised not to rise abruptly from a sitting or recumbent position and to avoid situations where injury could result if syncope occur. Concomitant use of alcohol, extensive periods of standing, prolonged or intense exercise, and exposure to heat can also precipitate orthostatic hypotension and should be minimized. If dizziness, lightheadedness or palpitations occur, the patient should sit or lie down, and seek medical attention if symptoms are recurrent or bothersome.

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.

Hypotension

Moderate:

silodosin

Silodosin has a moderate potential interaction with Hypotension.

Peripheral alpha 1- adrenergic receptor blocking agents (aka alpha 1- blockers) cause vasodilation and can produce marked hypotension, especially orthostatic hypotension with syncope or other postural symptoms such as dizziness, lightheadedness, and palpitations.

Liver Disease

Major:

silodosin

Silodosin has a major potential interaction with Liver Disease.

The use of silodosin is contraindicated in patients with severe hepatic impairment. No dosage adjustment is needed in patients with mild or moderate hepatic impairment.

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.

Psychosis

Major:

armodafinil

Armodafinil has a major potential interaction with Psychosis.

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.

Armodafinil has a moderate potential interaction with Psychosis.

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.

Renal Dysfunction

Major:

silodosin

Silodosin has a major potential interaction with Renal Dysfunction.

The use of silodosin is contraindicated in patients with severe renal impairment (CrCl < 30 mL/min). Caution and regular monitoring is recommended in patients with moderate renal impairment as the plasma concentrations can increase three times higher when compared with subjects with normal renal function. Dose should be reduced to 4 mg/day in patients with moderate renal impairment.

Syncope

Moderate:

silodosin

Silodosin has a moderate potential interaction with Syncope.
