Adverse Reaction

Adverse reactions refer to discomfort that has newly appeared or worsened more noticeably than usual after administration. Record the time and amount taken, meals, and any other medications taken together.

For difficulty breathing, swelling of the face, lips, or tongue, feeling of fainting, or severe chest pain, do not wait for a general inquiry and seek emergency medical care immediately.

How do I distinguish between adverse reactions and pre-existing symptoms?

Review chronologically whether the discomfort existed before administration, or if it newly appeared or became distinct after starting or increasing the dose. Note changes such as stomach discomfort, diarrhea, palpitations, drowsiness, insomnia, or rash, along with the amount taken per dose, meals, and other medications taken together. The fact that it occurred after administration does not alone confirm the cause, but safety verification should not be delayed.

What should I prepare if symptoms occur?

Keep the product, dispensing label, ingredient list, and remaining quantity, and prepare the time of the last dose and photos of the symptoms. Do not test whether the same reaction occurs by taking the medicine again without instructions from medical staff. Even if symptoms have mildened, if they worsened after repeated administration, you must report that sequence.

Are side effects, interactions, and allergies the same thing?

They are not the same. We evaluate and distinguish between predictable unwanted effects, interactions where the effect changes when used with other medications, foods, or supplements, and allergies, which are immune responses. MedlinePlus explains drug reactions in these three categories and advises that severe allergic reactions may require immediate treatment.
