There are currently no drugs available that can prevent a milk allergy from taking place. Instead, treatments are aimed at relieving allergy-related symptoms. 

Like other food allergies, allergic reactions to milk usually result in symptoms that affect the nose, throat, lungs, skin and gastrointestinal tract. These symptoms can be treated with several types of medications, including:

• Antihistamines. Medications that provide relief for more basic allergy reactions such as hives (smooth, raised pink or white bumps that appear on or beneath the skin), sneezing, runny nose and gastrointestinal symptoms. Antihistamines directly counteract the effects of histamines, chemicals which are responsible for most milk allergy symptoms.
  
  
• Bronchodilators. Medications that open the airways of the lungs, relieving symptoms such as shortness of breath or wheezing (a whistling or high-pitched sound that results when breathing tubes are narrowed or obstructed). They may be recommended for people whose milk allergies trigger asthma attacks or asthma-like symptoms. They are usually breathed directly into the lungs using an inhaler.
  
  
• Epinephrine injection. A synthetic form of adrenaline that, when injected, is a powerful bronchodilator, opening breathing tubes and restoring normal respiration quickly. It is usually reserved for the most severe allergic reactions that involve anaphylaxis (generalized reaction involving two or more body systems). Most physicians recommend that individuals who are susceptible to severe milk reactions carry an injection of epinephrine with them at all times and understand how to self–administer the drug. A medical alert bracelet or necklace is also a good idea for these individuals.
  
  
• Corticosteroids. Medications that reduce inflammation. These medications are most commonly used to treat severe allergic reactions in infants.

It is important to note that allergy medication should not be taken to prevent a reaction to a food. This action can have potentially fatal consequences. Avoidance is the only safe method of preventing an allergic reaction to a food allergen.  

Individuals should also note that antihistamines and bronchodilators are not alternatives to epinephrine and should not be used instead of epinephrine.
