The only reason I say red bull is because it contains caffine(far less than the amounts in your typical migraine meds but a bit more than a cup of coffee or soda) group b vitamins, sucrolose, ginsing, all within safe range for a one time drink during pregnancy.(not a drink for everyday during pregnancy) its actually one of the few drinks that has known ingredients vs other drinks that have stuff u don't know what it is and it works fast. It was recommended by my ob for a natural remedy for a migraine vs taking migraine meds. ( which i tried to avoid meds during pregnancy)As with all things its always best to ask a dr. Good luck.
I'm going to disagree with the person above me and don't drink redbull. Not a good idea. A regular soda with caffeine will work enough. But if tylenol, cool compresses, and caffeine isn't making it better then go get checked out. Especially if its one of the worse headaches you've had. Feel better!
Also forgot to mention eat some kind of nuts, the magnesium helps migraines and so does vitamin b2. Good luck
I would go to the er and get checked out. They can give you meds that are safe for you and baby. You can try some natural remedies, drink pure grape juice and a red bull, the caffine in the red bull helps and the grape juice is a vasoconstrictor.(hope I spelled it right) also use warm or cool compresses whichever feels better. If you try those and it doesn't help go to the er. Hope u feel better soon.
