Creatine and arcalion 200mg can it be safely combined?

Arcalion safe: Arcalion or sulbutiamine is a derivative of thamine or vitamin B1. Its clinical efficacy is uncertain; it has been used to treat asthenia, chronic fatigue, memory loss and even erctile dysfunction. It is an over the counter drug and considered safe. Creatine is safe at doses of no more than 3 grams per day. I could not find any interaction or contraindication of using both drugs.
