Disease interactions
21 potential interactions Applies to: 15 conditions, including Depression, Asthma, COPD, Narcolepsy, and Hypotension.
Alcoholism
Moderate:
daridorexant
Daridorexant has a moderate potential interaction with Alcoholism.
Patients with a history of abuse or addiction to alcohol or other substances may be at increased risk for abuse of or addiction to daridorexant and should be monitored closely.
Asthma
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with Asthma.
Oral anxiolytic, sedative, and hypnotic agents may cause respiratory depression and apnea when given in high dosages or following acute overdose. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are recommended.
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with Asthma.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Cardiovascular Conditions and Disorders
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Antihistamines may infrequently cause cardiovascular adverse effects related to their anticholinergic and local anesthetic (quinidine-like) activities. Tachycardia, palpitation, ECG changes, arrhythmias, hypotension, and hypertension have been reported. Although these effects are uncommon and usually limited to overdosage situations, the manufacturers and some clinicians recommend that therapy with antihistamines be administered cautiously in patients with cardiovascular disease, hypertension, and/or hyperthyroidism.
COPD
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with COPD.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Depression
Major:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a major potential interaction with Depression.
A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of most anxiolytics, sedatives and hypnotics. Some of these changes include decreased inhibition, aggressiveness, agitation, and hallucinations. These drugs can cause or exacerbate mental depression and cause suicidal behavior and ideation. Therapy with these drugs should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
daridorexant
Daridorexant has a moderate potential interaction with Depression.
Daridorexant can worsen depression and suicidal thoughts and actions and should be used with caution in patients with depression. These patients should be monitored closely and any preventive measures should be taken.
Drug Dependence
Moderate:
daridorexant
Daridorexant has a moderate potential interaction with Drug Dependence.
Patients with a history of abuse or addiction to alcohol or other substances may be at increased risk for abuse of or addiction to daridorexant and should be monitored closely.
Gastrointestinal Obstruction
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with Gastrointestinal Obstruction.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Glaucoma/Intraocular Hypertension
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Some hypnotic drugs can have an anticholinergic effect and should be used with caution in patients with glaucoma, and trouble urinating due to retention or enlarged prostate.

Liver Disease
Moderate:
daridorexant
Daridorexant has a moderate potential interaction with Liver Disease.
Daridorexant is not recommended in patients with severe hepatic dysfunction. The maximum recommended dosage in patients with moderate hepatic dysfunction is 25 mg once per night.
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with Liver Disease.
Limited pharmacokinetic data are available for the older, first-generation antihistamines. Many appear to be primarily metabolized by the liver, and both parent drugs and metabolites are excreted in the urine. Patients with renal and/or liver disease may be at greater risk for adverse effects from antihistamines due to drug and metabolite accumulation. Therapy with antihistamines should be administered cautiously in such patients. Lower initial dosages may be appropriate.
Moderate:
Silphen Cough
The diphenhydrAMINE in Silphen Cough has a moderate potential interaction with Liver Disease.
In general, anxiolytics, sedatives and hypnotics are extensively metabolized by the liver. Their plasma clearance may be decreased and their half-life prolonged in patients with impaired hepatic function. Therapy with these drugs should be administered cautiously in patients with liver disease (some are not recommended in severe liver impairment), and the dosage should be adjusted accordingly. Laboratory testing is recommended prior and during treatment.
