Well, you can use a slime weapon, as they make the fight easier. If you are not a fan of slime, get a good Ice Weapon. As for armour, I waited until I got G-rank equipment. Alatreon ALWAYS hits hard even when you have 600+ defense like my armor set does, so the best you can do is avoid all of it´s attacks. If you like Lances or G.Lances and are good with them use them because the shield comes in handy. Like every other monster you just need to prepare yourself. Since you can´t go to G-rank yet I would recommend a good slime weapon to make the fight more bearable or for farming  (Either a LS or a Hammer) or just using Ice and Dragon elements. Even G-rank armors can suffer from it´s hits so in armor matters, you use the best one you have or work hard to get to G-rank first. Make sure to bring some Nulberries as the Dragonblight is seriously annoying.

Good luck :)
