The issue of drug allergies?

I have some injuries to my spinal peripheral nerves, so I consulted a rehabilitation doctor who prescribed me medication.
After taking it for a while, I noticed red rashes on my limbs.
I then saw a dermatologist who diagnosed me with allergic dermatitis and gave me topical medication, but there was no improvement.
After taking the medication again, I carefully checked the prescriptions from the rehabilitation doctor and noticed that it mentioned to discontinue use immediately if allergic reactions occur: 1.
ACEO Rctard (discontinue if gastrointestinal discomfort or allergic reactions occur) 2.
Iwcll tab 3.
Aeicon (Aiinamin F) 4.
Songora.
Since I have been taking these medications for a while, could they be causing my skin allergy? Will the rashes disappear after stopping the medication, or do I need to take antihistamines? Additionally, due to my nerve injury, the doctor advised me to supplement with B12, but I noticed that the B12 I purchased is labeled "ChioKinate Capsules 500µg" and has side effects listed as: 1.
Digestive: loss of appetite, nausea 2.
Skin: occasional rashes.
Can I continue taking this?

Dear Billy:
(1) First, it is important to understand that when a drug allergy occurs, the medication should be discontinued, and the allergic symptoms should be observed to see if they improve, in order to confirm that it is a drug allergy and not due to other causes.
If the drug has caused a skin allergy, it typically improves after stopping the medication.
If the allergy is causing you significant discomfort, taking antihistamines can help alleviate the symptoms.
(2) Confirm the medications you are taking:
1.
ACEO Rctard: This is a pain-relieving and anti-inflammatory medication used to treat rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gout, myositis, tendonitis, tenosynovitis, and bursitis.
Possible side effects include rash, redness, itching, hives, and photosensitivity.
2.
Iwcll tab? Is it Iwell? This is used to treat excessive stomach acid, gastric ulcers, duodenal ulcers, and acute or chronic gastritis.
3.
Aeicon? (Aiinamin F)? Is it (Alinamin F)? This is used to treat neuritis, pain, symptoms of vitamin B1 deficiency, postoperative intestinal paralysis, and eye fatigue.
The likelihood of the second and third medications causing a rash is relatively low.
4.
Songora: This is used to treat peripheral vascular circulation disorders and may occasionally cause rashes.
5.
Qine capsule: This is used to improve peripheral neuropathy and may occasionally cause rashes.
The pain-relieving and anti-inflammatory medication has the highest likelihood of causing your drug allergy.
It is recommended that you discontinue this medication first, while continuing the other medications.
If topical ointments are needed, they can be used as appropriate.
If it can be confirmed that ACEO is the cause, please inform your physician during your follow-up visit to adjust the pain medication, and ask the pharmacist to assist in recording the medication name on your medication record card.
Present this card during future medical visits to avoid misuse.
Wishing you health and happiness.

More Info

Understanding drug allergies is crucial for anyone taking medication, especially if you have experienced adverse reactions like skin rashes. Drug allergies can manifest in various ways, and recognizing the symptoms, understanding the risks, and knowing how to manage them is essential for your health and safety.

Symptoms of Drug Allergies
Drug allergies can present with a range of symptoms, which may include:
1. Skin Reactions: This is the most common manifestation and can include rashes, hives, or itching. In your case, the red rashes on your limbs could be a sign of an allergic reaction to one of the medications prescribed by your rehabilitation doctor.

2. Respiratory Issues: Some individuals may experience difficulty breathing, wheezing, or nasal congestion.

3. Gastrointestinal Symptoms: Nausea, vomiting, diarrhea, or abdominal pain can also occur.

4. Anaphylaxis: This is a severe, life-threatening allergic reaction that requires immediate medical attention. Symptoms include swelling of the throat, difficulty breathing, rapid pulse, and loss of consciousness.

Risks Associated with Drug Allergies
The risks of drug allergies can vary depending on the individual and the medication involved. Some people may have mild reactions that resolve quickly after discontinuing the drug, while others may experience severe reactions that can lead to hospitalization. It’s important to note that drug allergies can develop at any time, even if you have taken the medication before without any issues.

Management of Drug Allergies
1. Immediate Action: If you suspect that a medication is causing an allergic reaction, the first step is to stop taking the drug immediately. In your case, since the rehabilitation doctor prescribed medications that indicate a risk of allergic reactions, it would be prudent to discontinue them and consult your healthcare provider.

2. Consulting Healthcare Professionals: After stopping the medication, it is advisable to follow up with your healthcare provider or a specialist, such as an allergist or dermatologist, to discuss your symptoms and explore alternative treatments.

3. Antihistamines: Over-the-counter antihistamines can help alleviate mild allergic symptoms, such as itching and rashes. However, it’s essential to consult your doctor before starting any new medication, especially if you are already on other treatments.

4. Monitoring Symptoms: Keep track of your symptoms and any new medications you take. This information can be valuable for your healthcare provider in determining the cause of your allergic reaction.

Regarding Your B12 Supplement
As for the B12 supplement you mentioned, it’s important to consider the potential side effects. If the label indicates that it can cause skin rashes, you should be cautious. If you suspect that the B12 supplement is contributing to your skin issues, it may be wise to stop taking it and discuss this with your healthcare provider. They can help determine whether you should continue with the supplement or explore alternative forms of B12 that may be better tolerated.

Conclusion
In summary, it is possible that the medications prescribed by your rehabilitation doctor are causing your skin rash, especially since they have warnings regarding allergic reactions. Discontinuing the medications and consulting with your healthcare provider is the best course of action. Additionally, be cautious with any supplements you take, as they can also cause allergic reactions. Always communicate openly with your healthcare providers about any adverse effects you experience, and they can guide you in managing your medications and allergies effectively.
