Hello Doctor,
I received a penicillin shot for syphilis treatment two months ago, but I still have rashes in my penis area. Am I getting better?
Hello,
Thank you for reaching out to Dr. Galen. Please find the below response to your query.
The rashes you're experiencing are likely due to a Jarisch-Herxheimer reaction, a common side effect of antibiotic treatment for syphilis. This reaction occurs as the spirochete bacteria die off and can cause rashes in areas such as the penis, usually within the first 24 hours after receiving penicillin. The rash typically resolves on its own within a week and may not require any treatment. In some cases, oral steroids can be prescribed to ease symptoms. If you've completed the full course of penicillin, your body is responding to the treatment, and you are likely progressing toward recovery. If you have concerns, it's a good idea to follow up with your doctor, but this rash is generally not a cause for alarm.
Thanks
