In fact, sometimes a person may get better after a severe allergic reaction but then have symptoms come back even stronger several hours later, which is called biphasic anaphylaxis, he adds. “You should go to the ER and stay there for at least four hours to make sure the symptoms are under control,” Sicherer says.

What to do if a patient has an allergic reaction?
Immediately call 911 or your local medical emergency number. Ask the person if he or she is carrying an epinephrine autoinjector (EpiPen, Auvi-Q, others) to treat an allergic attack. If the person says he or she needs to use an autoinjector, ask whether you should help inject the medication.
What anaphylaxis feels like?
Anaphylaxis causes your immune system to release a flood of chemicals that can cause you to go into shock — your blood pressure drops suddenly and your airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.
What are the 4 types of allergic reactions?
Allergists recognize four types of allergic reactions: Type I or anaphylactic reactions, type II or cytotoxic reactions, type III or immunocomplex reactions and type IV or cell-mediated reactions.
Can Urgent Care treat allergic reaction?
You should visit an urgent care center as soon as a non-life-threatening reaction begins. A physician will be able to determine the cause of the reaction, treat it and provide you with options for handling symptoms going forward.
Can you survive anaphylaxis without treatment?
This is a dangerous and life-threatening situation called anaphylactic shock. Symptoms of anaphylaxis can be mild, and they may go away on their own (most anaphylactic reactions will require treatment). But it’s difficult to predict if or how quickly they will get worse.
What happens if you leave an allergic reaction untreated?
When inflamed, sinuses are not as good at draining fluid. They provide the perfect place for bacteria to accumulate, grow, and cause infection. Untreated allergies may also worsen other chronic problems such as asthma, and skin disorders like eczema and hives. These are just some physical complications.
Does drinking water help an allergic reaction?
So, water actually has the power to regulate your histamine levels. This does not mean drinking water can act to prevent or treat an allergic reaction, but it’s good to know that avoiding dehydration by drinking water will help to maintain normal histamine activity.
What is the first line treatment for anaphylaxis?
Epinephrine (1 mg/ml aqueous solution [1:1000 dilution]) is the first-line treatment for anaphylaxis and should be administered immediately. In adults, administer a 0.3 mg intramuscular dose using a premeasured or prefilled syringe, or an autoinjector, in the mid-outer thigh (through clothing if necessary).
What is the best medicine for allergic reaction?

Can anaphylaxis occur hours later?
Some reactions can occur after several hours, particularly if the allergen causes a reaction after it has been eaten. In very rare cases, reactions develop after 24 hours. Anaphylaxis is a sudden and severe allergic reaction that occurs within minutes of exposure.
What are the stages of an allergic reaction?
These antibodies travel to cells that release histamine and other chemical mediators, which cause allergy symptoms to occur. The human body carries out an allergic cascade in three stages: sensitization, “early-phase,” and “late-phase.”
