Can you take Guaifed Caps with Sustiva?

The efavirenz in Sustiva has a moderate potential interaction with Alcoholism.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

The phenylephrine in Guaifed Caps 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.

The phenylephrine in Guaifed Caps 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.

The phenylephrine in Guaifed Caps 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.

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.

The efavirenz in Sustiva has a moderate potential interaction with Depression.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

The phenylephrine in Guaifed Caps 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.

The efavirenz in Sustiva has a moderate potential interaction with Drug Dependence.

During clinical trials, efavirenz was associated with an increase in the occurrence of serious psychiatric events, including severe depression, suicidal ideation, nonfatal suicide attempts, aggressive behavior, paranoid reactions, and manic reactions. Other factors associated with an increased occurrence of these psychiatric symptoms were history of injectable drug use, psychiatric history, or use of psychiatric medications at study entry; similar associations were observed in the efavirenz and control groups. Therapy with efavirenz should be administered cautiously in patients with current/history of psychiatric illness, emotional instability, or substance abuse. Patients with serious psychiatric adverse reactions should receive prompt medical evaluation to assess the possibility that symptoms are related to efavirenz use, and if so, to determine whether the risks of continued therapy outweigh the benefits.

The phenylephrine in Guaifed Caps 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.

The phenylephrine in Guaifed Caps has a major potential interaction with Hyperthyroidism.

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.

The efavirenz in Sustiva has a moderate potential interaction with Liver Disease.

Efavirenz is not recommended for patients with moderate or severe liver dysfunction; insufficient data are available to determine whether dose adjustment is needed. Patients with mild liver dysfunction may receive efavirenz without dose adjustment. Due to extensive CYP450-mediated metabolism and limited clinical experience in patients with liver dysfunction, therapy with efavirenz should be administered cautiously in patients with mild liver dysfunction; careful monitoring is recommended for these patients. In addition, postmarketing cases of hepatitis (including fulminant hepatitis progressing to liver failure requiring transplantation or resulting in death) have occurred during therapy with efavirenz; reports have included patients with underlying liver disease (including coinfection with hepatitis B or C). Monitoring of liver enzymes before and during therapy is recommended for all patients.

The efavirenz in Sustiva has a moderate potential interaction with Long QT Syndrome.

QTc prolongation has been observed with the use of efavirenz. Alternatives to efavirenz should be considered when administered to patients at higher risk of torsade de pointes or when coadministered with a medication with known risk of torsade de pointes.

The phenylephrine in Guaifed Caps has a major potential interaction with Pheochromocytoma.

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.
