Conclusion of this page
If you experience swelling of the face, lips, tongue, or throat, difficulty breathing or swallowing, or dizziness and fainting, do not wait for a response from the prescribing institution and immediately call 119 or visit an emergency medical institution.
The cause is not confirmed by skin photos alone; please prepare a timeline including the actual medication taken, the last dose, any new food, medicine, supplements, or cosmetics, and the time the rash started and spread.
Even if symptoms subside, do not resume the same product on your own to test it, and do not attempt the next dose after adding antihistamines or ointment.
If you do not know the name, ingredients, and dosage of your medication, you may apply incorrect information even if it is categorized as 'weight loss medicine.' This page does not replace individual prescription changes or emergency medical care.
For skin reactions, check breathing and swelling before looking at photos
After taking diet herbal medicine, Gambi-jeong, or Gambi-hwan, you may experience red spots, itching, hives, or edemathese symptoms may occur. However, it is impossible to determine from photos alone whether it is due to the medication, drug adverse reactionan allergy, or other causes such as food, infection, or cosmetics.
First, check if the face, lips, tongue, or throat are swelling, or if there is difficulty breathing or swallowing, or a change in voice. If these signs are absent, prepare the actual medication taken and a timeline of administration and exposure.
If these signs are present, go immediately to 119 or an emergency medical institution
If swelling of the face, lips, tongue, or throat, wheezing, difficulty breathing, difficulty swallowing, dizziness, a feeling of fainting, and generalized hives appear together, do not wait for an online response from the prescribing institution. Seek help immediately if symptoms spread rapidly or if consciousness becomes clouded.
If blisters or skin peeling occur along with a rash, or if there is pain or sores on the mucous membranes of the mouth, eyes, or genitals, or a high fever, a prompt in-person evaluation is required. Do not drive yourself; bring the product packaging and a complete list of medications taken.
Verify the actual prescribing institution and product for Gambi-jeong and Gambi-hwan
Gambi-jeong, Gambi-hwan, and diet hwan do not refer to a single standard ingredient or content. Verify the prescribing institution, formulation, actual dose, start date, and time of the last dose. If the product is dispensed in small portions and you are unsure of the product, bring the remaining medication and packaging as they are.
Do not apply the dosage instructions of Baekrok Gambi-jeong to Gambi-hwan from other institutions, and Baekrokdam will not determine the re-administration or dosage for prescriptions it cannot identify.
Specifically distinguish and record rash, hives, and edema
Note whether they are flat red spots, hives where the skin is raised and changes position, or if the eyes, lips, hands, and feet are actually swelling. Record whether it is itchy or painful, if the color changes when pressed, where it first appeared, and the direction in which it is spreading.
Do not determine a diagnosis by comparing photos online. Even if they look the same, the cause and urgency may differ.
Create a timeline of medication intake and skin changes
Record the time the product was taken, the time the rash was first noticed, the time it was most severe, and the time it subsided. Include whether it was the first dose or a product taken previously, and if the dose or frequency was recently changed. If other medications or supplements were used together, interactions Check for possibilities within the same timeline.
The fact that symptoms have disappeared does not guarantee that it is safe to resume medication. Before attempting the next dose, send the timeline and photos to the original prescribing institution.
Include everything newly taken or applied on the same day
List not only prescription drugs, over-the-counter drugs, cold medicines, and painkillers, but also other herbal medicine, supplements, new foods, and alcohol, as well as cosmetics, detergents, hair dyes, insect bites, and infection symptoms. Even if you think you "only took Gambi-hwan," there may have been exposures that were different from usual.
Pre-selecting a single cause may result in missing information necessary for medical evaluation. Keep photos of the front and back of the product and the names of newly used items as they are, as much as possible.
Dry mouth and swelling of the face or tongue are not the same symptom
A feeling of dryness in the mouth must be distinguished from actual swelling of the tongue, lips, or throat. If there is swelling visible in the mirror, or changes in speaking, swallowing, or breathing, Dry Mouth Guidedo not wait while reading the guide; respond as if it is an emergency symptom.
Even if you are unsure if it is swelling, if it worsens rapidly or if your voice or breathing changes, err on the side of safety and seek help immediately.
Do not resume medication arbitrarily or mask symptoms
Do not take the same product again to check for a reaction just because symptoms have subsided. Avoid arbitrarily adding antihistamines, ointments, steroids, or someone else's medication while continuing to take Gambi-jeong.
If you have already used over-the-counter medication, inform the medical staff of the drug name, dosage, time, and changes in symptoms. If you have emergency symptoms, do not delay requesting help to look for medication or organize photos.
Take both overall and close-up photos along with the time
In a brightly lit area, take separate photos of the entire affected area of the rash and close-up views. Record changes over time using the same distance and lighting, and photograph the face so that swelling of the eyes or lips is visible. Do not edit photos or apply filters.
Do not delay medical evaluation even if you do not have photos. Writing down the time of onset, itching, pain, breathing, swallowing, new exposures, and current status is sufficiently helpful.
Set the boundary between today's inquiry and record observation
Even if there are no emergency symptoms, if the rash spreads or recurs, if the face or area around the eyes swells, or if it interferes with daily life or sleep, notify the original prescribing institution on the same day before taking further doses. If there is high fever, pain, or mucosal symptoms, check the necessity of an in-person evaluation.
Even for very localized changes that are decreasing, record the product and time, and consult if they persist or recur. Do not judge these as "healing crises" (myeonghyeon reaction) or weight loss signals based on the internet.
If the skin is peeled from scratching due to itching or if you cannot sleep, it is a change that impairs daily functioning even if the area is small. Also report if there is heat, pain, or oozing at the rash site, or if it is accompanied by fever and body aches. Conversely, do not assume safety just because it looks faint in photos; determine the timing of medical evaluation based on the actual rate of spread and systemic symptoms.
Please report skin symptoms during medication via the Baekrokdam online consultation
Those taking Baekrok-gambi-jeong should send medication guidance, the time of the last dose, skin photos, and a timeline of new medications, foods, and products to the Baekrokdam online consultation. Dr. Choi Yeon-seung will advise whether emergency or in-person evaluation, pausing or stopping medication, or switching to other treatments or prescriptions is necessary.
For Gambi-jeong or Gambi-hwan from other institutions, notify the original prescribing institution first, as they know the actual composition. If the prescribing institution cannot be identified and symptoms persist, show the product to a nearby medical institution or pharmacist.
In the next medical evaluation, preventing re-exposure takes priority over confirming the cause
During the medical evaluation, we check for previous allergies, exposure to the same ingredients or products, and the timing of skin reactions in relation to other medications, foods, or infections. If necessary, we will refer you to appropriate care, such as allergy or dermatology specialists, and avoid re-administration while the cause remains unclear.
If Baekrokdam Gambijeong is not suitable for you, or if a skin or allergy evaluation is currently a priority, we may discontinue the weight loss prescription or consider alternative treatments. Enduring skin reactions is not the goal of treatment.
7-DAY FOLLOW-UP
Record these six things together rather than just a single weight number
Do not arbitrarily increase the dose when progress is slow or there is discomfort. If you leave the following records in the Baekrokdam online questionnaire, they can be reviewed in connection with your current prescription.
- Actual dosage and time
Write the actual number of tablets and the times taken over the past 7 days, not the guided amount.
- Appetite and food intake
Record the times when hunger is strongest, the frequency of late-night snacks or treats, and changes in meal portions.
- Weekly weight trend
Look at the 7-day trend measured under the same conditions rather than a single day's value.
- Sleep, bowel movements, and discomfort
Please record the time you fell asleep, and the start time of any constipation, diarrhea, throbbing, hand tremors, or stomach discomfort.
- Items taken together
Please list the names and times of any prescription drugs, over-the-counter medications, supplements, other diet-related Korean herbal medicines, or caffeine.
- Reason for requesting adjustment
Please specify whether you wish to change the dosage or timing due to the rate of weight loss, discomfort, or changes in your schedule.
Verification of Evidence
What the evidence says and what it cannot say
Official guidance on adverse drug reactions distinguishes hives and rashes as common skin manifestations of drug allergies, and anaphylaxis as a rare but potentially life-threatening reaction.
- Meaning in My Situation
- Do not stop at simply stating that something appeared on the skin; you must first ask about breathing, swallowing, consciousness, and swelling of the face or tongue to determine the level of urgency.
- Limitations of Interpretation
- It is impossible to confirm whether a specific medication or Korean herbal medicine is the cause based on skin symptoms alone; professional medical evaluation is required to assess the cause of the allergy.
Guidance for anaphylaxis patients treats swelling of the throat or tongue, difficulty breathing, wheezing, dizziness, fainting, and rapid systemic reactions as emergency symptoms.
- Meaning in My Situation
- If there is swelling of the face or tongue and breathing discomfort, you must seek emergency help immediately without waiting for a response to your inquiry about Gambijeong.
- Limitations of Interpretation
- Online symptom charts are not self-diagnostic tools for anaphylaxis; if symptoms worsen rapidly, medical evaluation takes priority even if the cause is uncertain.
Guidance on drug allergies explains that reactions can occur not only with new medications but also with medications used previously without issues, and that the full medication history and timing of onset are important.
- Meaning in My Situation
- Prepare a chronological list of all medications, Korean herbal medicine, supplements, and over-the-counter drugs, and do not arbitrarily attempt to take them again just because symptoms have subsided.
- Limitations of Interpretation
- It is difficult to distinguish between allergic and non-allergic rashes by appearance alone, and the causative ingredient cannot be confirmed without photos and a medical evaluation.
During medical evaluation
How will this information be verified during a medical evaluation?
Individual prescriptions cannot be determined by public guides alone. During a medical evaluation, the name and dosage of medications being taken, medical history, and current symptoms are verified together.

Questions
Frequently Asked Questions
If I get hives after taking Gambijeong, is it a side effect?
It could be a reaction related to the medication, but food, other medications, supplements, and infections must also be checked. If you experience swelling of the face or tongue, or difficulty breathing or swallowing, seek emergency help immediately. Otherwise, send photos and a timeline to Baekrokdam before your next dose.
If a few red spots appear on my skin, can I continue taking Gambihwan?
Ingredients cannot be identified by the name 'Gambihwan' alone, and safety cannot be confirmed through photos alone. Record the time of the last dose, the start and spread of the rash, and any new foods or medications, then contact the original prescribing institution before taking further doses.
If the hives subside, can I try taking it one more time?
Do not arbitrarily re-take the medication to identify the cause. Since it is impossible to judge at home whether a reaction may be more severe upon re-exposure, please receive a medical evaluation with the product and reaction records.
What is the difference between a dry mouth and a swollen tongue?
A feeling of dryness is different from actual swelling. If your tongue, lips, or throat swell, your voice changes, or you have difficulty breathing or swallowing, do not view it as simple dry mouth and immediately call 119 or visit an emergency medical institution.
How should I take and send photos?
In a brightly lit area, take one photo of the overall distribution and one close-up photo, and note the time of first discovery and spread. For the face, record the swelling of the eyes and lips, but do not delay emergency care to take photos.
I developed a rash after taking diet pills from another Korean medicine clinic; can I still inquire with Baekrokdam?
If you have emergency symptoms, please visit a medical institution immediately regardless of the medication. If it is not an emergency, first notify the original prescribing institution that knows the actual composition; consultations for new treatments at Baekrokdam will proceed separately after evaluating your current reaction.
