When to see a doctor

Call 911 now: struggling to breathe, too breathless to walk or talk, or lips turning blue or gray. An asthma inhaler at its maximum dose that has not helped.
Call 911 now: swelling of the lips, mouth, throat or tongue, or fast, struggling breathing after an allergy tablet or injection. Use the epinephrine pen if you have one.
The ER now: a nosebleed lasting longer than 10 to 15 minutes, a heavy one, or one with weakness, dizziness or trouble breathing.
Urgent care or your doctor today: face pain and swelling with feeling very unwell, or pain that painkillers do not touch.
Your doctor this week: a wheeze, a night cough, a tight chest, or shortness of breath. Asthma that is getting worse or waking you at night.
Your doctor: a nose blocked on one side that does not go away, nosebleeds, blood in the mucus, face pain or numbness, or lost smell. Double vision: right away.
Your doctor: symptoms getting worse, not helped by pharmacy medicines, affecting sleep and daily life, or a cause you are not sure of.

I am not a doctor. This is not medical advice. This is self-education. Every dose on this page is the one a trial or a label used, quoted from it. It is not a prescription. Talk to a physician who has your history before any medicine or procedure. Wheeze, breathlessness, or a nose blocked on one side: see a doctor first.
