Disease interactions
15 potential interactions Applies to: 13 conditions, including High Blood Pressure, Arrhythmia, Liver Disease, Skin Cancer, and Interstitial Lung Disease.
Arrhythmia
Moderate:
Zelboraf
The vemurafenib in Zelboraf has a moderate potential interaction with Arrhythmia.
Vemurafenib can cause dose dependent QT prolongation which may lead to an increased risk for ventricular arrhythmias, including Torsade de Pointes. It is recommended not to start treatment in patients with uncorrectable electrolyte abnormalities, QTc > 500 ms, or long QT syndrome, or in patients who are taking medicinal products known to prolong the QT interval. Evaluate patients prior to and following treatment initiation or after dose modification for QTc prolongation, evaluate ECG and electrolytes (including potassium, magnesium, and calcium) periodically, and thereafter as clinically indicated. Vemurafenib should be withhold in patients who develop QTc > 500 ms. Upon recovery to QTc <= 500 ms, restart at a reduced dose and it should be permanently discontinued if the QTc interval remains > 500 ms and increased > 60 ms from pre-treatment values after controlling cardiac risk factors for QT prolongation (e.g., electrolyte abnormalities, congestive heart failure, and bradyarrhythmias).
Arteriovenous Shunting
Major:
methylergonovine
Methylergonovine has a major potential interaction with Arteriovenous Shunting.
The amine ergot alkaloids, ergonovine and methylergonovine, can cause serious cardiovascular complications because of their vasospastic effects. Hypertension (more often with ergonovine) has been most commonly reported, particularly when administered IV undiluted or at an excessive rate or when used in conjunction with regional anesthesia or vasoconstrictors. Headaches, seizures, cerebrovascular accidents and death have been associated with the hypertensive episodes. Other, less common adverse effects include acute myocardial infarction, transient chest pains, thrombophlebitis, tachycardia and palpitations. Therapy with ergot alkaloids should generally be avoided, except under special circumstances, in patients with chronic hypertension, preeclampsia or eclampsia, cardiovascular disease, cerebrovascular disease, or peripheral vascular disease. Caution is advised when these agents are administered to patients with venoatrial shunts, mitral valve stenosis, or sepsis. Close monitoring of cardiovascular status is highly recommended during therapy.

Dermatitis, Drug-Induced
Moderate:
Zelboraf
The vemurafenib in Zelboraf has a moderate potential interaction with Dermatitis, Drug-Induced.
Severe dermatologic reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and mild to severe photosensitivity can occur in patients treated with vemurafenib. Consider dose modifications for intolerable >= Grade 2 photosensitivity. It is recommended to advise patients to avoid sun exposure, wear protective clothing and use a broad-spectrum UVA/UVB sunscreen and a suitable lip balm when outdoors while on vemurafenib treatment. Permanently discontinue vemurafenib in patients who experience a severe dermatologic reaction.
Electrolyte Abnormalities
Moderate:
Zelboraf
The vemurafenib in Zelboraf has a moderate potential interaction with Electrolyte Abnormalities.
Vemurafenib can cause dose dependent QT prolongation which may lead to an increased risk for ventricular arrhythmias, including Torsade de Pointes. It is recommended not to start treatment in patients with uncorrectable electrolyte abnormalities, QTc > 500 ms, or long QT syndrome, or in patients who are taking medicinal products known to prolong the QT interval. Evaluate patients prior to and following treatment initiation or after dose modification for QTc prolongation, evaluate ECG and electrolytes (including potassium, magnesium, and calcium) periodically, and thereafter as clinically indicated. Vemurafenib should be withhold in patients who develop QTc > 500 ms. Upon recovery to QTc <= 500 ms, restart at a reduced dose and it should be permanently discontinued if the QTc interval remains > 500 ms and increased > 60 ms from pre-treatment values after controlling cardiac risk factors for QT prolongation (e.g., electrolyte abnormalities, congestive heart failure, and bradyarrhythmias).
High Blood Pressure
Major:
methylergonovine
Methylergonovine has a major potential interaction with High Blood Pressure.
The use of the amine ergot alkaloids, ergonovine and methylergonovine, is considered by some clinicians to be contraindicated in patients with hypertension. These agents can cause hypertension, particularly when administered IV undiluted or at an excessive rate or when used in conjunction with regional anesthesia or vasoconstrictors. Headaches, seizures, cerebrovascular accidents and death have been associated with the hypertensive episodes. Patients with chronic hypertension or preeclampsia may be at increased risk for these complications. Of the two agents, methylergonovine has less tendency to cause hypertension, although preferably neither agent should be administered to at- risk patients.
History, Skin Cancer
Moderate:
Zelboraf
The vemurafenib in Zelboraf has a moderate potential interaction with History, Skin Cancer.
Cutaneous squamous cell carcinoma, keratoacanthoma, and melanoma occurred at a higher incidence in patients receiving vemurafenib. Potential risk factors associated included age (> 65 years), prior skin cancer, and chronic sun exposure. It is recommended to perform dermatologic evaluations prior to initiation of therapy and periodically thereafter as clinically indicated. Consider dermatologic monitoring for 6 months following discontinuation of vemurafenib.
Interstitial Lung Disease
Moderate:
Zelboraf
The vemurafenib in Zelboraf has a moderate potential interaction with Interstitial Lung Disease.
The use of certain multikinase inhibitors has been associated with pulmonary toxicity. Serious cases of interstitial lung disease (ILD), including fatal cases and interstitial pneumonitis or pulmonary fibrosis have been reported. Caution is recommended when using these agents in patients with a history of interstitial pneumonitis or pulmonary fibrosis or those patients presenting with acute onset of new or progressive unexplained pulmonary symptoms such as dyspnea, cough, and fever pending diagnostic evaluation. If ILD is confirmed, these agents should be permanently discontinued and appropriate measures should be instituted. Treatment should be immediately withheld in patients diagnosed with ILD/pneumonitis and permanently discontinued if no other potential causes of ILD/pneumonitis have been identified.
Liver Disease
Moderate:
methylergonovine
Methylergonovine has a moderate potential interaction with Liver Disease.
The amine ergot alkaloids, ergonovine and methylergonovine, appear to be eliminated by both renal and hepatic routes.
