Indeed it is! Always better to look for the simple solution first!

Italian and French BBs use right-hand threads on the drive-side. The problem with that is the pressure around the inside of the cup against the BB shell rotates the cup in a counterclockwise direction which unscrews it. (One can say the French were crazy for having done so but the Italians must have had a very good reason for it!)

Anyway, the solution is to get it really tight. Normal hand-tight isn't enough. You don't need Loctite (though some people say it's the only solution), you just need to get it really really really tight. You need to good BB wrench and you need to grunt it home, or whack it with a dead-weight mallet, or do anything to get it really really really tight. And add a few more really's.
