Requip xl 2mg x 2

Sorry this may seem a very very dumb question but if I'm out of my 4mg tablets, can I take 2x2mg ?

I'm assuming yes of course, but because of the xl one a day nature I thought I'd just double check
Yes , i did when i ran out of 4s , no problem , in fact i was taking 3 x 2mg tablets when my daily dosage was 6mg
Cheers sparky :-)
