Drug interactions

Moderate drug interactions

Moderate:

phenylephrine semaglutide

Applies to: Guaifen PE (guaifenesin / phenylephrine) and semaglutide

Phenylephrine may interfere with blood glucose control and reduce the effectiveness of semaglutide and other diabetic medications. Monitor your blood sugar levels closely. You may need a dose adjustment of your diabetic medications during and after treatment with phenylephrine. 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:

semaglutide Food/Lifestyle

Applies to: semaglutide

Food may affect the absorption of semaglutide when taken orally. It is recommended that oral semaglutide be taken 30 minutes before first food, beverage, or other oral medications of the day with no more than 4 ounces of plain water. You may experience more side effects including nausea, vomiting, and diarrhea if you fast longer than 30 minutes after the semaglutide dose. Talk to a healthcare provider 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:

phenylephrine Caffeine

Applies to: Guaifen PE (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, Diarrhea, Gastroparesis, Hyperthyroidism, and Diabetes Mellitus.

Benign Prostatic Hyperplasia

Moderate:

Guaifen PE

The phenylephrine in Guaifen PE 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:

Guaifen PE

The phenylephrine in Guaifen PE 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.

Cerebrovascular Insufficiency

Major:

Guaifen PE

The phenylephrine in Guaifen PE 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.

Dehydration

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Dehydration.

There have been postmarketing reports of acute kidney injury (sometimes requiring hemodialysis) in patients treated with semaglutide. The majority of events occurred in patients with gastrointestinal adverse reactions leading to dehydration (e.g., nausea, vomiting, diarrhea); therefore, semaglutide is not recommended in patients with severe gastroparesis. It is recommended to monitor renal function in patients reporting adverse reactions to semaglutide that may lead to volume depletion, especially when initiating or escalating doses of semaglutide.

Diabetes Mellitus

Moderate:

Guaifen PE

The phenylephrine in Guaifen PE 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.

Diabetic Retinopathy

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Diabetic Retinopathy.

Patients with history of diabetic retinopathy should be monitored for progression of diabetic retinopathy during treatment with semaglutide. Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy.

Diarrhea

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Diarrhea.

There have been postmarketing reports of acute kidney injury (sometimes requiring hemodialysis) in patients treated with semaglutide. The majority of events occurred in patients with gastrointestinal adverse reactions leading to dehydration (e.g., nausea, vomiting, diarrhea); therefore, semaglutide is not recommended in patients with severe gastroparesis. It is recommended to monitor renal function in patients reporting adverse reactions to semaglutide that may lead to volume depletion, especially when initiating or escalating doses of semaglutide.

Gastroparesis

Moderate:

semaglutide

Semaglutide has a moderate potential interaction with Gastroparesis.

Glaucoma/Intraocular Hypertension

Moderate:

Guaifen PE

The phenylephrine in Guaifen PE 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.
