Movicol is a laxative that works by drawing water into your bowel. Because it speeds up the movement of your digestive system, it can potentially wash other medicines through your body before they have had a chance to be properly absorbed. This could make your other medicine less effective.

Why this happens
Movicol (macrogol) increases the speed of gastrointestinal transit. This can reduce the time available for the absorption of other orally administered medications.
What you should do

Treatment and medication
Can I take 7.5mg and Medikinet together?

Additionally, while Medikinet is active, it may be harder for you to fall asleep, even after taking Zopiclone. In some cases, mixing stimulants and sedatives can lead to unpredictable effects on your coordination, heart rate, or mental state (such as feeling confused or agitated).

Taking Folitrax (methotrexate) and Hqtor (hydroxychloroquine) together can increase the risk of side effects, particularly those affecting the liver.
