Drug interactions
Moderate drug interactions
Moderate:
senna vemurafenib
Applies to: Laxacin (docusate/senna) and vemurafenib
Vemurafenib can cause an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect.
The risk is increased if you have:
- a heart condition called congenital long QT syndrome
- other cardiac diseases
- conduction abnormalities
- electrolyte disturbances, such as low blood levels of magnesium or potassium
These electrolyte disturbances can occur with bowel cleansing preparations or excessive use of medications that have a laxative effect, such as senna.
Do not exceed the dose and duration recommended on the product label or prescribed by your doctor.
You should seek immediate medical attention if you experience sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether taken together or separately.
In addition, you should let your doctor know if you experience signs and symptoms of low magnesium or potassium blood level such as:
- weakness
- tiredness
- drowsiness
- dizziness
- confusion
- tingling
- numbness
- muscle pain
- cramps
- nausea
- vomiting
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:
senna multivitamins with minerals
Applies to: Laxacin (docusate/senna)
Chronic use of senna may reduce your body's ability to absorb certain vitamins (A, D, E, and K) and minerals like calcium.
To reduce the risk of diminished absorption of multivitamins with minerals, it is best to use senna only occasionally or for short periods. If your doctor does prescribe these medications together, you may need a dose adjustment or special test to safely use both medications.
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
14 potential interactions Applies to: 14 conditions, including Arrhythmia, Inflammatory Bowel Disease, Liver Disease, Skin Cancer, and Interstitial Lung Disease.
Appendicitis
Major:
Laxacin
The senna in Laxacin has a major potential interaction with Appendicitis.
The use of stimulant laxatives is contraindicated in patients with or who may have acute surgical abdomen or appendicitis. These patients may be candidates for emergency surgery. Stimulant laxatives should also not be administered to patients with abdominal pain, particularly if the cause has not been determined.
Arrhythmia
Moderate:
vemurafenib
Vemurafenib 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).
Bleeding Disorder
Major:
Laxacin
The senna in Laxacin has a major potential interaction with Bleeding Disorder.
The use of stimulant laxatives is contraindicated in patients with anal or rectal fissures. These preparations may cause irritation, burning sensation, and proctitis.
Dermatitis, Drug-Induced
Moderate:
vemurafenib
Vemurafenib 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:
vemurafenib
Vemurafenib 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.
