dextromethorphan Food/Lifestyle

Applies to: Duraphen DM (dextromethorphan / guaifenesin / phenylephrine)

Alcohol can increase the nervous system side effects of dextromethorphan such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dextromethorphan. Do not use more than the recommended dose of dextromethorphan, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Moderate:

phenylephrine Caffeine

Applies to: Duraphen DM (dextromethorphan / guaifenesin / phenylephrine)

Both phenylephrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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

15 potential interactions Applies to: 15 conditions, including Benign Prostatic Hyperplasia, Hyperthyroidism, Peptic Ulcer, Diabetes Mellitus, and Acidosis.

Acidosis

Moderate:

tolazoline

Tolazoline has a moderate potential interaction with Acidosis.

The therapeutic efficacy of tolazoline in reducing persistent vasoconstriction and pulmonary hypertension may be pH dependent. Acidosis may decrease the efficacy of tolazoline.

Alkalosis

Moderate:

tolazoline

Tolazoline has a moderate potential interaction with Alkalosis.

The histamine-releasing properties of tolazoline can stimulate gastric secretion resulting in hypochloremic alkalosis, stress ulcers, and GI bleeding. Therapy with tolazoline should be administered cautiously in patients with GI disorders such as gastritis, enteritis, or peptic ulcer disease.

Benign Prostatic Hyperplasia

Moderate:

Duraphen DM

The phenylephrine in Duraphen DM has a moderate potential interaction with Benign Prostatic Hyperplasia.

Sympathomimetic agents may cause or worsen urinary difficulty in patients with prostate enlargement due to smooth muscle contraction in the bladder neck via stimulation of alpha-1 adrenergic receptors. Therapy with sympathomimetic agents should be administered cautiously in patients with hypertrophy or neoplasm of the prostate.

Cardiovascular Conditions and Disorders

Major:

Duraphen DM

The phenylephrine in Duraphen DM has a major potential interaction with Cardiovascular Conditions and Disorders.

Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

Cerebral Vascular Disorder

Major:

tolazoline

Tolazoline has a major potential interaction with Cerebral Vascular Disorder.

The use of tolazoline is contraindicated in patients with coronary artery disease or insufficiency or following a cerebrovascular accident. Hypotension due to decreased peripheral vascular resistance results from direct relaxation of vascular smooth muscle and alpha adrenergic blockade. Heart rate and cardiac output are increased.

Cerebrovascular Insufficiency

Major:

Duraphen DM

The phenylephrine in Duraphen DM has a major potential interaction with Cerebrovascular Insufficiency.

Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

Diabetes Mellitus

Moderate:

Duraphen DM

The phenylephrine in Duraphen DM has a moderate potential interaction with Diabetes Mellitus.

Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.

Gastrointestinal Hemorrhage

Moderate:

tolazoline

Tolazoline has a moderate potential interaction with Gastrointestinal Hemorrhage.

The histamine-releasing properties of tolazoline can stimulate gastric secretion resulting in hypochloremic alkalosis, stress ulcers, and GI bleeding. Therapy with tolazoline should be administered cautiously in patients with GI disorders such as gastritis, enteritis, or peptic ulcer disease.

Glaucoma/Intraocular Hypertension

Moderate:

Duraphen DM

The phenylephrine in Duraphen DM has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

Sympathomimetic agents can induce transient mydriasis via stimulation of alpha-1 adrenergic receptors. In patients with anatomically narrow angles or narrow-angle glaucoma, pupillary dilation can provoke an acute attack. In patients with other forms of glaucoma, mydriasis may occasionally increase intraocular pressure. Therapy with sympathomimetic agents should be administered cautiously in patients with or predisposed to glaucoma, particularly narrow-angle glaucoma.
