diphenhydrAMINE daridorexant

Applies to: Silphen Cough (diphenhydramine) and daridorexant

Using diphenhydrAMINE together with daridorexant may increase side effects such as:

  • dizziness
  • drowsiness
  • confusion
  • difficulty concentrating

Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination.

What to do: You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you.

Talk to your doctor if you have any questions or concerns. 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:

daridorexant Food/Lifestyle

Applies to: daridorexant

Do not consume grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with daridorexant unless directed otherwise by your doctor.

Grapefruit juice can increase the blood levels of daridorexant. This may increase the risk of side effects such as:

  • somnolence
  • fatigue
  • abnormal sleep behaviors
  • worsening of depression or suicidal thoughts
  • headache

You should avoid the use of alcohol while being treated with daridorexant. Alcohol can increase the nervous system side effects of daridorexant such as:

  • dizziness
  • drowsiness
  • reduced coordination

Some people may also experience complex sleep behaviors such as sleepwalking, sleep driving, preparing and eating food or doing other activities while not fully awake that you may not remember the next morning.

Talk to your doctor if you have any questions or concerns. 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.

Moderate:

diphenhydrAMINE Alcohol (Ethanol)

Applies to: Silphen Cough (diphenhydramine)

Ask your doctor before using diphenhydrAMINE together with ethanol (alcohol).

Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking diphenhydrAMINE.

You should be warned not to exceed recommended dosages and to avoid activities requiring mental alertness.

If your doctor prescribes these medications together, you may need a dose adjustment to safely take this combination.

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.

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.

Narcolepsy

Major:
