Can you take Dihydroergotamine with 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).

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.

Dihydroergotamine has a major potential interaction with High Blood Pressure.

The use of ergot alkaloids is contraindicated in patients with conditions predisposing them to vasospastic reactions, including, ischemic heart disease (angina, history of myocardial infarction, silent ischemia), peripheral vascular disease, sepsis, shock, vascular surgery, uncontrolled hypertension, and severely impaired hepatic or renal function. The vasoconstriction produced be ergot alkaloids may exacerbate these conditions. Ergot alkaloids may cause vasospastic reactions other than coronary artery vasospasm such as peripheral vascular reactions, and colonic ischemia, causing muscle pains, numbness, coldness, pallor, and cyanosis of the digits. In patients with compromised circulation, persistent vasospasm may result in gangrene or death. Nitroprusside and heparin have been used to treat ergotamine- induced severe vasoconstriction.

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.

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.
