Drug interactions

Moderate drug interactions

Moderate:

polyethylene glycol 3350 with electrolytes abiraterone

Applies to: Co-Lav (polyethylene glycol 3350 with electrolytes) and abiraterone

Abiraterone 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 low blood levels of magnesium or potassium, which can occur with bowel cleansing preparations or excessive use of medications that have a laxative effect.

You should use polyethylene glycol 3350 with electrolytes exactly as prescribed by your doctor, and drink plenty of clear liquids before, during, and after the cleansing process to avoid becoming dehydrated.

Your doctor may be able to recommend specific fluids you can drink before starting polyethylene glycol 3350 with electrolytes to help maintain your electrolyte levels. He/she may also want to monitor your electrolyte levels and/or heart rhythm.

You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications.

In addition, you should let your doctor know if you experience signs and symptoms of low electrolyte levels 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:

polyethylene glycol 3350 with electrolytes Food/Lifestyle

Applies to: Co-Lav (polyethylene glycol 3350 with electrolytes)

Mixing polyethylene glycol 3350 with electrolytes and starch-based food thickeners can reduce the thickening effect, which could increase the chance of the liquid going down the wrong way (aspiration), especially if you have trouble swallowing.

Also, taking oral medications within one hour of starting polyethylene glycol 3350 with electrolytes may speed up movement through your digestive system, potentially reducing the absorption and effectiveness of those medications.

Try to avoid taking other oral medications during and within one hour after starting polyethylene glycol 3350 with electrolytes.

It's important to inform 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:

abiraterone Food/Lifestyle

Applies to: abiraterone

This interaction does not apply to abiraterone acetate (Yonsa) 125 mg tablets, which can be taken with or without food.

Taking abiraterone with food increases the amount of medicine that gets absorbed by the body for certain formulations. This may increase the risk of side effects such as high blood pressure, water retention, and a condition called hypokalemia (low blood potassium), which in severe cases can lead to muscle weakness, paralysis, breathing and swallowing difficulties (due to muscle paralysis), and irregular heart rhythm.

What to do: You should take abiraterone once a day on an empty stomach. No food should be eaten for at least two hours before and one hour after taking abiraterone.

Let your doctor know if you experience:

  • nausea
  • vomiting
  • constipation
  • abdominal cramping
  • confusion
  • dizziness
  • lightheadedness
  • fainting
  • muscle weakness
  • muscle cramps
  • numbness or tingling
  • rapid heartbeat
  • chest pain
  • swelling in the legs or feet

These may be symptoms of hypokalemia or excessive effects of abiraterone.

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.
