diphenhydrAMINE somatrem

Applies to: Snooze Fast (diphenhydramine) and somatrem
Monitor

Coadministration with human growth hormone (hGH) receptor agonists may alter the clearance and plasma concentrations of medicinal products that are metabolized by CYP450 isoenzymes. The mechanism of this interaction may be mediated via the effects of hGH receptor agonists on expression of different CYP450 isoenzymes. The labeling of some hGH receptor agonists specify that this interaction may be the most significant for substrates of CYP450 3A4 and/or 1A2 and indicate that their clearance may be increased. However, clinical data are limited, and clinical significance is unknown. In a study of 11 growth hormone (GH)-deficient adults randomized to GH or placebo for 6 months followed by 3 months of GH for all subjects, antipyrine clearance, a non-specific marker of hepatic CYP450 activity, increased in all subjects who received GH treatment compared to placebo. In vitro studies have indicated that GH enhanced CYP450 3A4 gene expression; however, other studies have suggested that when administered in a pulsatile fashion, CYP450 3A4 activity is reduced. A study in healthy elderly men did not reveal any effects on CYP450 3A4 or 2D6 but did demonstrate induction of 1A2 and inhibition of 2C19. Given that studies have varied in the type of growth hormone used, dosing regimens, ages and sexes of the patients and/or cell lines utilized, it is difficult to predict how coadministration may affect the CYP450 substrate.

Management

Careful monitoring is advised when drugs that are metabolized by CYP450 isoenzymes are used in combination with hGH receptor agonists. As this interaction's clinical significance is unknown, the label of the specific hGH receptor agonist and CYP450 substrate(s) being coadministered should be consulted for more specific guidance.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

diphenhydrAMINE Alcohol (Ethanol)

Applies to: Snooze Fast (diphenhydramine)
Generally avoid

Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system. No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.

Management

Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.

Disease interactions

17 potential interactions Applies to: 13 conditions, including Depression, Underactive Thyroid, Asthma, COPD, and Hypotension.

Asthma

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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.

Diabetes Mellitus

Moderate:

somatrem

Somatrem has a moderate potential interaction with Diabetes Mellitus.

The use of growth hormone has been associated with resistance to insulin. Patients with diabetes mellitus or impaired glucose tolerance should be observed closely during therapy. The dose of antihyperglycemic drugs (insulin or oral/injectable agents) may require adjustment.

Gastrointestinal Obstruction

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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:

Snooze Fast

The diphenhydrAMINE in Snooze Fast has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

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.

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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.

Hyperthyroidism

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast has a moderate potential interaction with Hyperthyroidism.

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.

Hypotension

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast has a moderate potential interaction with Hypotension.

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.

Liver Disease

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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.

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast 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.

Renal Dysfunction

Underactive Thyroid

Moderate:

somatrem

Somatrem has a moderate potential interaction with Underactive Thyroid.

The use of growth hormone has been associated with the development of hypothyroidism. Patients should be monitored baseline and periodically for adequate thyroid function. Inadequate treatment of hypothyroidism may inhibit the optimal response to growth hormone.

Urinary Retention

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast has a moderate potential interaction with Urinary Retention.

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.

Moderate:

Snooze Fast

The diphenhydrAMINE in Snooze Fast has a moderate potential interaction with Urinary Retention.

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
