Considering the Discontinuation of Antibiotic Treatment

8/2/2025, 8:10:25 PMMale25-34

At 35 years of age, I recently found myself in an unexpected situation. A little over a week ago, while I was fast asleep, I was bitten by a venomous spider, which startled me awake, causing me to tumble out of bed. This incident occurred on a Thursday night, and by Friday morning, I observed a deep bluish-purple mark on my skin, nearly black, encircled by a red halo. After conducting some research, I suspect it may have been a recluse spider bite, due to the distinctive appearance of the area. The following day, several individuals remarked on how I appeared unwell, despite feeling relatively okay myself. However, when I woke up Saturday, I discovered that my foot was somewhat swollen and exhibited redness. Initially, I assumed this was a normal bodily response, but out of an abundance of caution, I decided to visit an Urgent Care facility. While there, the staff examined my bite briefly and prescribed me antibiotics. It had been many years since I last took antibiotics, likely when I was a child under ten, so this was a new experience for me. I was given sulfamethoxazole, a folic acid antagonist, for a duration of ten days, and I commenced the treatment that Saturday. By the next day, I noticed that the appearance of the bite had improved significantly, leading me to believe that the antibiotics might not have been necessary after all, yet I continued the regimen. By Wednesday, I began to experience side effects, which intensified into Thursday and Friday. I developed a few painful ulcers in my mouth—one of the known reactions to the medication. Additionally, I encountered considerable discomfort in one of my sinuses, especially while swallowing food or liquids. Today, Saturday, I noticed that the sinus pain has somewhat diminished. Given all of this, I'm seriously contemplating terminating the antibiotic course, as I feel that my condition did not warrant such treatment in the first place.

It sounds like you’ve been through quite a challenging experience with the spider bite and the subsequent antibiotic treatment. It’s understandable to be concerned about the necessity of antibiotics, especially when you are experiencing side effects. Here’s a structured response to address your situation:

Main Points

  1. Antibiotic Necessity: Antibiotics like sulfamethoxazole are generally prescribed in cases where there is a high risk of a bacterial infection following specific types of bites. However, if you are improving, that is encouraging.
  2. Recognizing Side Effects: The oral ulcers and sinus discomfort you’re experiencing are indeed potential side effects of the medication.
  3. Discontinuing Antibiotics: If you're considering stopping the treatment, it’s essential to weigh the risks and benefits based on your recovery so far.

Explanation

You experienced a potentially serious spider bite, which understandably led to concern about possible infection. Antibiotics are often prescribed to prevent or treat infections, especially with venomous bites like that of a recluse spider. However, if the bite is healing and you are not showing signs of ongoing infection (like fever, increasing redness, or discharge), it might suggest that the antibiotics are not needed.

Your side effects, such as mouth ulcers and sinus discomfort, can sometimes occur with antibiotics. It’s crucial to listen to your body and consider how these side effects are impacting your quality of life.

Next Steps

  1. Monitor Symptoms: Keep an eye on the bite area and any other symptoms. Look for changes like increased redness, warmth, swelling, or discharge, which could indicate infection.
  2. Consider Discontinuation: If your symptoms continue to improve and you're still experiencing discomfort from the side effects, it may be reasonable to stop taking the antibiotic. Before doing so, however, weigh how you are feeling overall.
  3. Consult a Healthcare Provider (if possible): While it is often ideal to get a healthcare professional’s advice before stopping medications, if this is not feasible, make an informed choice based on your symptom management.
  4. Hydration and Oral Care: Stay hydrated, and consider using saltwater rinses for mouth ulcers to help relieve discomfort.

It’s important to trust your instincts about your health. If you choose to stop the antibiotics and notice any concerning symptoms, or if there’s no improvement, seeking medical advice would be the best course of action.

Managing Severe Reactions to Black Henna: Steps to Heal Your Skin

On January 25, I decided to get a dragon design in black henna while in Boracay. Initially, I felt a slight tingling sensation on my skin, which later intensified to a burning feeling especially when exposed to sunlight. Upon returning home, my instinct was to scrub the henna off with soap. Unfortunately, this led to my skin becoming swollen, reddened, itchy, and even blistered. To soothe the irritation, I used a gentle cleanser like Cetaphil to cleanse the area thoroughly, ensuring it was completely dry afterward. Once dried, I applied a thin layer of petroleum jelly. I also began taking antihistamines such as Cetirizine or Loratadine, which provided some relief from the itching. Additionally, I tried to shield the affected area from sun exposure as much as I could. A few days into this routine, I introduced 1% hydrocortisone cream, layering it with petroleum jelly afterward. During my time in the city, I shifted to using Benadryl cream and continued taking antihistamines to diminish the itchiness, but I didn’t have any hydrocortisone cream available. Although the henna stain has nearly faded, the design has left a noticeable imprint on my skin. Once back home, I restarted my treatment by applying 1% hydrocortisone cream followed by a layer of Cetaphil PRO AD Derma Skin Restoring Moisturizer. I’m concerned about potential discoloration on my skin from this reaction. Currently, the skin looks flat and somewhat darker with slight bumps. I would greatly appreciate any advice on how to minimize hyperpigmentation and what treatments I can undertake to support healing.

Should You Be Concerned About Numbness with Bruising After a Week?

I’m a 19-year-old female with no notable medical background or current medications. A week ago, I took a spill while skating and landed hard on my hip, resulting in a large, swollen bump on the back of my upper thigh. Initially, I used the RICE method for two days, and the bruise developed into a dark purple and blue mark, roughly 12 centimeters wide. During the first few days, I experienced discomfort while walking, yet I stayed fairly active by going for walks and dancing. The pain has lessened to just mild soreness when I make sudden movements like jumping. Currently, the bruise has changed to a reddish-purple hue, indicating some healing, but I am still experiencing numbness in the area. While there seems to be a slight improvement in the sensation, it’s hardly noticeable. Do you think I should seek medical advice? By the way, I’m of Indian descent, stand 5'6'' tall, weigh 58 kilograms, and consume alcohol occasionally.
