Except in unusual circumstances, oxytocin should not be administered in the following conditions: prematurity, borderline cephalopelvic disproportion, previous major surgery on the cervix or uterus including cesarean section, over-distention of the uterus, grand multiparity, or invasive cervical carcinoma. Because of the variability of the combinations of factors which may be present in the conditions listed above, the definition of “unusual circumstances” must be left to the judgment of the physician. The decision can only be made by carefully weighing the potential benefits which oxytocin can provide in a given case against rare but definite potential for the drug to produce hypertonicity or tetanic spasm.
It's still not exactly clear what causes the connection between exercise and anaphylaxis. There are a number of working theories about the mechanism involved, tied to the physiological changes that happen in the body during exercise. Increased blood flow might push sensitive immune cells around the body, for instance. Or perhaps certain proteins in the gut change their behavior during exercise, interacting with food in ways that could cause an allergic reaction. And since exercise increases the absorption of material from the gastrointestinal tract, it's possible that there are simply more allergens able to make their way into the body during a workout.
Carry Epinephrine for emergencies. Kits containing fast-acting, self-administered epinephrine are commonly prescribed for people who are at risk of anaphylaxis. Make sure that you carry an epinephrine kit with you at all times, and that family and friends know of your condition, your triggers and how to use epinephrine. Consider wearing an emergency medical bracelet or necklace identifying yourself as a person at risk of anaphylaxis. Teachers and other caregivers should be informed of children who are at risk for anaphylaxis and know what to do in an allergic emergency.
