Since it is not a narcotic or psychotropic drug, there is no need to take any additional documentation with you, e.g. a doctor's certificate or a prescription.
The medicine should be dispensed in its original packaging with a leaflet, in the amount needed for the duration of your stay abroad, e.g. 1-2 blisters, unless you are planning a longer trip (here depending on your needs). It is worth taking an extra blister in case you damage the tablets or miss a tablet, for example.

It is best to carry the tablets in your hand luggage, in case your checked baggage is lost.
