Drug interactions

Moderate drug interactions

Moderate:

bisacodyl PAZOPanib

Applies to: Gen Lax (bisacodyl) and pazopanib

PAZOPanib 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, or 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 bisacodyl. 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, or 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

Major food/lifestyle interactions

Major:

PAZOPanib Food/Lifestyle

Applies to: pazopanib

Do not consume grapefruit or grapefruit juice during treatment with PAZOPanib unless directed otherwise by your doctor. Grapefruit juice can increase the blood levels of PAZOPanib, which may lead to an increased risk of serious side effects such as liver damage, irregular heart rhythm, bleeding, high blood pressure, heart attack, and stroke. Taking PAZOPanib with food can also significantly increase its absorption and levels in the blood. Therefore, you should take PAZOPanib on an empty stomach, at least one hour before or two hours after eating. Call your doctor immediately if you develop fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. You should also seek immediate medical attention if you experience signs and symptoms that could indicate cardiovascular problems such as sudden dizziness; lightheadedness; fainting; fast or pounding heartbeats; chest pain or tightness; pain in your arms, back, neck, or jaw; shortness of breath; numbness or weakness on one side of your body; and slurred speech or difficulty speaking. 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 food/lifestyle interactions

Moderate:

bisacodyl multivitamins with minerals

Applies to: Gen Lax (bisacodyl)

Chronic use of bisacodyl 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 bisacodyl 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.
