Concerns About Transdermal Thyroid Medication Exposure

8/2/2025, 4:01:07 AMMale25-34

As a 25-year-old female currently taking care of my boss’s cat, I’ve been administering transdermal thyroid medication to the feline's ear for the past few days. It’s been quite a challenge due to the cat’s spirited and less-than-cooperative nature. While I’ve used gloves during the application, there was a mishap this evening when the cat tilted her head at an inopportune moment. This resulted in some of the medication gel landing on my neck—yikes! I promptly washed it off with soap and water, but now I find myself a bit anxious after reading alarming information online about possible side effects from exposure. I’m trying to remind myself not to panic, especially since the prescribed dosage for cats is likely low enough to pose minimal risk for humans. Also, since I acted quickly to remove it, I’m hoping that lessens any potential issue. I’m reaching out to see if anyone with a medical background can provide reassurance, as I’d like to settle my worries and get a good night’s sleep! For reference, the specific medication I have been using is methimazole compounded at a dosage of 1.25 mL.

It's completely understandable to feel anxious after an incident involving medication exposure, but based on the situation you've described, there are a few important points to consider that can help reassure you.

Key Points:

  1. Low Risk of Significant Exposure: The amount of methimazole that possibly got on your skin is likely minimal and the risk of significant side effects for a healthy adult from a small accidental exposure is very low.
  2. Prompt Washing: You acted quickly by washing the area with soap and water, which is the best immediate action to mitigate any potential effects of skin exposure.

Explanation:

Methimazole is used primarily to treat hyperthyroidism in cats. While there can be side effects in humans through significant exposure, such as skin irritation or, in very rare cases, systemic effects, your situation involves a minimal exposure due to the small amount that landed on your skin. Since you used gloves most of the time and promptly washed off any residue, this further reduces the likelihood of any harmful effects. Most general information indicates that occasional accidental exposure doesn't usually lead to noteworthy issues for adults.

Prioritized Next Steps:

  1. Monitor for Any Changes: Keep an eye on the area where the medication touched your skin for any signs of irritation or unusual reactions (redness, itching).
  2. Stay Informed but Calm: Limit further research to reputable medical sources as excessive reading can often heighten anxiety without providing new insights or reassurance.
  3. Practice Relaxation Techniques: Engage in calming activities this evening to help you settle down and prepare for a restful night. Breathing exercises, reading, or listening to soothing music can help ease anxiety.
  4. Consult a Professional If Needed: If you notice any unusual changes in your skin or if you experience any unexpected symptoms within the next couple of days, seek guidance from a healthcare professional.

You're doing a great job caring for your boss's cat, and it's natural to be concerned about medication safety. Take a deep breath; chances are you are perfectly fine, and your proactive steps have further minimized any risk.

Intense Pain in Left Thumb

Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.

Resources for Safe Mouse Cleanup

While it may not be a typical inquiry for a healthcare professional, I find myself in need of guidance. Recently, we had an uninvited mouse visitor in our home, and unfortunately, it left droppings in my children's toy storage and on the changing table. I am seeking advice on how to effectively disinfect all affected items or determine if disposal is necessary to prevent any health risks. My children are quite young, at 2.5 years and just 4 months old. If they’ve potentially been exposed to mouse droppings, should I reach out to their pediatrician? For reference, I’m a 32-year-old female, standing at 5'6" and weighing 140 pounds, not currently on any medications.

Excessive Electrical Shocks Encountered

Hello everyone! This is my inaugural post here since I don't frequently use Reddit. I'm a 15-year-old male, and I've recently been experiencing an unusual frequency of electrical shocks. Whenever I come into contact with anything that is either highly charged or conductive, I receive a sharp, irritating jolt. This situation has become increasingly bothersome. For instance, I can only grasp my Mac charger by the cord and not the plug itself. I'm curious if anyone has insights into why this is happening. Please let me know; I hope it's nothing serious! 💕
