Allergic reactions to Meds are tricky. Obviously its best to consult a Physician ASAP for their opinion. My daughter had a reaction to ammoxicilin and it took a few days for the swelling and rash to go away. The medicine stays in your system longer then you realize. Some people need steroids to reduce swelling and an antihistamine like Benydryl. Its safe to say that you need to give it a few days for the fluid of the swelling to go away and back to normal. Keep antihistamines in your purse (or if a guy, in your pocket or vehicle at all times.) Benadryl is the best and for adults two caps (25 mgs. each) are what you should take. It takes only 10 to 15 minutes for the swelling to go down, but if you've left it for a long time it may take longer. DO NOT DRIVE A VEHICLE OR MACHINERY WHILE TAKING ANTIHISTIMINES. Benadryl is given in hospitals (I know because I had a reaction to a medication) and is harmless to you. It will probably make you sleepy.

Are you allergic to Flucloxacillin after being prescribed this antibiotic I have noticed I get severe stomach cramps afterwards. I've looked up online for mixed results?

No, that is not really an allergic reaction. Antibiotics should usually be taken with food, because they can cause stomach distress. If that doesn't help, you can ask for a different antibiotic, if the stomach distress is too much for you, and doesn't go away. Technically, your reaction just means that you have a sensitivity. If you'd like to know the difference, an allergic reaction could eventually lead to death, if you continue taking the medication. A sensitivity is more like an annoying side effect.

Yes. If you are allergic to something, it is best to stay away from it completely.

Others only have an allergic reaction if they eat the item they are allergic to. Make sure to ask your doctor about the severity of your allergy before you go near anything you are allergic to!
