After an allergic reaction, if chest tightness and shortness of breath occur, prompt medical attention at a hospital is essential. Antiallergic medications should be administered promptly. Additionally, monitor for signs such as tachycardia (increased heart rate). In cases of severe allergy, intravenous fluid therapy is required to replenish bodily fluids, and supplemental oxygen should be provided to alleviate hypoxia and prevent further worsening of respiratory distress.
