Why this happens
Vitamin B6 speeds up the process of levodopa breaking down in the body before it has a chance to reach the brain. If the medicine breaks down too early, it cannot work properly to manage your condition.
What you should do
Back to contentsDo not take vitamin B6 supplements (including multivitamins containing B6) while taking levodopa unless specifically told to by your doctor.

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

Medikinet is a stimulant designed to wake you up and help you focus, while Zopiclone is a sedative designed to make you sleepy. Taking them at the same time can make both medicines less effective. 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).
