Complevit is a combination of the 3 essential neurotropic vitamins (B1, B6 and B12) in high dosage. Vitamins B1, B6 and B12 are of special importance for the metabolism in the peripheral and central nervous system. Their effect on the regeneration of nerves has been shown in various investigations using the vitamins individually and in combination.
Vitamin B1 plays an important role in major metabolic processes. Vitamin B6 has an analgesic effect. Vitamin B12 ensures blood cell formation and prevents degenerative processes of the nervous system. Both the individual function and the beneficial biochemical links between the 3 vitamins justify their combined use.

It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you take this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to ensure that the combination is safe.
You should not take other medicines that contain paracetamol in combination with this medicine, as this can easily result in exceeding the maximum recommended daily dose of paracetamol. Many cold and flu remedies and over-the-counter painkillers contain paracetamol, so be sure to check the ingredients of any other medicines before taking them with this one. Migraleve yellow can be taken four hours after taking Migraleve pink if you still have a migraine, but make sure you do not exceed the maximum dose recommended in the information leaflet.
This medicine should be used with caution in people taking a monoamine oxidase inhibitor (MAOI), for example the antidepressants phenelzine, tranylcypromine or isocarboxacid. Ask your doctor or pharmacist for advice before taking this medicine if you have taken an MAOI in the last 14 days.
Cholestyramine reduces the absorption of paracetamol from the gut. It should not be taken within an hour of taking paracetamol or the effect of the paracetamol will be reduced.
Metoclopramide and domperidone may increase the absorption of paracetamol from the gut.
Long-term or regular use of paracetamol may increase the anti-blood-clotting effect of warfarin and other anticoagulant medicines, leading to an increased risk of bleeding. This effect does not occur with occasional painkilling doses. If you are taking an anticoagulant medicine and you are also taking co-codamol regularly, your blood clotting time (INR) should be regularly monitored.
