Can Controloc cause drowsiness?

Is it possible that I am very tired and sleepy for half a day taking Controlloc 20 on an empty stomach? I would like to add that the nutritionist suggested a deficiency of B vitamins.

Controloc uncommonly (affects between 1 and 10 people in 1000 people) causes side effects such as weakness and tiredness. The leaflet does not state that side effects in the form of drowsiness are observed. Long-term use of this drug, however, can cause deficiencies of vitamin B12, magnesium or iron, and their deficiency may be the cause of weakness and drowsiness. In such a situation, it is worth considering supplementation with magnesium and B vitamins and performing a blood count to exclude anemia.
