Welcome to icliniq.com. I would like to know her age, other medical conditions, and present medicines. Fainting needs to be evaluated as it can recur and cause serious problems. If she is still feeling unwell, or having giddiness (a tendency to fall), or lost consciousness, you should get her to the emergency room. In the emergency room, they will be able to check your blood pressure, heart rate, and basic blood tests. If you are back to normal, then you can meet your primary care physician in the clinic at the earliest. You can also call your primary care physician office to check with them as they will be aware of your previous medical issues and current medicines. I hope this helps.
