Is It Anesthesia Allergy? Reactions After Dental Procedures

Is it an allergic reaction to anesthesia?

Hello, doctor.
During my previous tooth extraction, I received Ubistesin Forte as anesthesia.
After the extraction, I suddenly felt dizzy and fainted for about 5 seconds.
When I came to, I had no idea what had happened.
I would like to ask if this could be an allergic reaction to the anesthesia? I previously asked another doctor, and he mentioned it might be due to the absorption of the anesthetic or vasovagal syncope.
Later, when I had a tooth extraction without Ubistesin Forte, I did not experience these symptoms.
I also saw online that there are tests for anesthetic drug allergies; where can I get this done?

1.
The literature indicates that allergic reactions to Ubistesin forte are very rare, with an incidence rate of less than 0.01%.
2.
Common drug allergic reactions typically manifest as skin symptoms, including rashes and itching.
In cases of more severe anaphylactic shock leading to loss of consciousness, it is generally not the case that one would faint for only five seconds and then regain consciousness spontaneously.
Considering these two points, your fainting episode lasting five seconds followed by spontaneous recovery does not seem to be indicative of a drug allergy.
If it is not caused by a drug allergy, identifying the potential causes would generally require more detailed information about the incident, which cannot be easily resolved through simple online communication.
If you are still concerned and wish to undergo drug allergy testing, Chang Gung Memorial Hospital in Taipei has established a drug allergy reaction center.

More Info

Experiencing dizziness or fainting after receiving anesthesia during a dental procedure can be concerning, and it's understandable that you're worried about the possibility of an allergy to the anesthetic used, in this case, Ubistesin Forte. However, it's important to clarify that the symptoms you experienced may not necessarily indicate an allergic reaction.

An allergic reaction to anesthesia typically manifests as skin rashes, hives, swelling, or respiratory difficulties shortly after administration. In contrast, the symptoms you described—dizziness and fainting—are more likely related to other factors, such as vasovagal syncope, which is a common response to stress, pain, or anxiety during medical procedures. This condition occurs when your body overreacts to certain triggers, leading to a sudden drop in heart rate and blood pressure, which can result in fainting.

It's also possible that the dizziness you experienced was due to the absorption of the anesthetic into your bloodstream, particularly if the injection was administered in a way that allowed the anesthetic to enter a blood vessel. This can lead to transient symptoms like dizziness or lightheadedness. The fact that you did not experience these symptoms when a different anesthetic was used suggests that it may be related to the specific formulation or administration technique of Ubistesin Forte.

If you are concerned about a potential allergy, it is advisable to consult with an allergist or a medical professional who specializes in drug allergies. They can perform specific tests to determine if you have an allergy to the anesthetic agents used in dental procedures. These tests may include skin prick tests or blood tests to assess your immune response to the anesthetic components.

In the meantime, if you have a history of anxiety or stress related to dental procedures, it may be beneficial to discuss this with your dentist. They can provide strategies to help manage anxiety, such as sedation dentistry options, which can make your experience more comfortable and reduce the likelihood of a vasovagal response.

It's also essential to communicate any previous reactions or concerns with your dental care provider before undergoing any procedures. This will allow them to take appropriate precautions and choose the most suitable anesthetic options for your needs.

In summary, while your symptoms after the use of Ubistesin Forte were concerning, they are more likely related to vasovagal syncope or the pharmacokinetics of the anesthetic rather than an allergy. Consulting with a specialist can provide clarity and peace of mind regarding your reactions to anesthesia. Always prioritize open communication with your healthcare providers to ensure safe and effective care tailored to your individual health needs.
