How Long Does an Allergic Reaction Last?

Published: Last Updated on

An allergy is an excessive reaction to a substance that, for most people, does not cause problems. The person who usually suffers from allergies suffers from inflammation, which unhealthy foods and habits can increase.

The time it takes to resolve an allergic reaction is highly variable. It will depend on factors such as the person’s state of health, how long the substance remains in contact with the body, and what medication is used to improve symptoms.

If you are interested in knowing how long it takes for an allergic reaction to disappear, continue reading this FastlyHealarticle.

What is an allergic reaction?

It is precisely an exaggerated way of acting for your body against a substance that does not cause problems for other people.

The substance you are allergic to can come into contact with you on your skin, it can be in the air, or you can ingest it. When that happens, your body triggers a series of inflammatory responses. These inflammatory responses can be mild or more severe and will remain as long as you stay in contact with what is causing your allergy.

Allergy symptoms

An allergic reaction can manifest itself in different areas of the body. When having contact with the allergenic substance, you can develop, among other symptoms:

  • Rash or hives on the skin.
  • Rhinitis with clear nasal discharge and sneezing.
  • Conjunctivitis.
  • Pharyngitis.
  • Shortness of breath due to glottis edema
  • Asthma.
  • Diarrhea.

When that happens, your body has mobilized many inflammatory cells and substances. This reaction will continue and can get worse if you continue to be in contact with the implication that caused it.

How long does an allergic reaction last?

When asked how long it takes for an allergic reaction to disappear, we can say that the answer is not so simple. An allergic reaction depends on:

  • The health status of the person.
  • Whether or not the allergen continues to contact the allergic person.
  • If medication is used to stop the allergic reaction.

Health condition

It is essential to see how the allergic person is doing and not just avoid contact with what causes the allergic reaction.

It is like glass about to overflow, filled with the last drop. Can we blame the last drop for the spill? Just as that last drop is not the culprit that the glass overflows its contents, the allergenic substance is not the only cause of the entire reaction, and it is essential to know the imbalance present. Often, the body of an allergic person has inflammation. We are not talking about external and visible inflammation only but of inflammatory reactions within the body facilitated by the accumulation of toxins.

As with most health problems, evaluating digestion as a first step is essential. This must be normal for the rest of the body to function correctly. This is achieved through a healthy and natural diet. The excess of processed products, dairy products, preservatives, colorings, and refined products goes hand in hand with most chronic diseases, including allergies. Therefore, a healthy diet and ensuring physical and mental harmony are essential for an allergic reaction to resolve faster.

Contact with the allergen

If a person in physical imbalance who is allergic to a particular substance in the environment comes into contact, an allergic reaction will occur.

If this substance continues in contact with your skin, your airway, or your digestive tract, the inflammatory reaction will likely continue. On the other hand, the body will gradually decrease its inflammatory response by moving away from that substance.

Drug use

When an allergic reaction is significant, anti-allergy and anti-inflammatory drugs can be used to reduce the body’s response. Eye drops, nasal sprays, bronchial sprays, tablets, or injectable medication can be used depending on the affected area.

Often, these drugs begin to take effect after a short time, especially if corticosteroids accompany them, but you should know that this medication will only cover the symptoms. That is, it will not solve the cause of the allergy.

Natural remedies for an allergic reaction

If you want an allergic reaction to last less time, you can use one of the following natural remedies. You should know that they do not solve the cause of the imbalance either, but they can help you without generating the adverse effects of the drugs.


Both powdered and fresh, ginger helps reduce inflammation and improves circulation. You can drink 2 or 3 cups a day.


Adding honey to your diet is very beneficial. It is not only for its anti-inflammatory properties but also because it helps reduce the number of secretions in the body, helps treat gastrointestinal discomfort, and reduces pain.


This fragrant herb is perfect for clearing the airway and reducing inflammation. Therefore, if the allergy manifests itself with secretions or coughs, you can benefit by breathing in the steam of an infusion of eucalyptus.
