Skin Rashes
One of the most immediate and noticeable symptoms of an antipsychotics allergy is the appearance of skin rashes. These can take several forms, ranging from red, itchy patches to raised bumps or hives. The rashes can appear anywhere on the body.
Difficulty Breathing
Particularly severe allergic reactions to antipsychotics may result in difficulty breathing. This can manifest as wheezing, shortness of breath, or a feeling of tightness in the chest.
Swelling
Swelling, particularly of the face, tongue, or throat, can occur as a result of an allergy to antipsychotics. This symptom can be particularly dangerous if it interferes with breathing.
Uncontrolled Muscle Movements
Some antipsychotics can cause tardive dyskinesia, a condition that results in uncontrolled muscle movements, often around the mouth. This can be a sign of an adverse reaction to the medication.
Fever
Antipsychotics allergy may cause a person run a fever. This is the body's natural response to what it perceives as a harmful invasion, and it might rise as it tries to kill the allergen.
Dizziness or Fainting
Dizziness, lightheadedness or fainting can be a symptom of an allergy to antipsychotics, potentially indicating a drop in blood pressure or other systemic reaction to the medication.
