Hi,
First of all, it doesn't seem to be
herpes according to your description.
Tetralysal is Lymecycline which belongs to a group of medicines known as
Tetracycline antibiotics. It has some serious side effects like
allergic reaction, ulcerations or lesions on mouth, lips, genital area; soreness or itching of the genital area, itchiness,
skin rash or hives; blistering or peeling of large areas of skin etc.
You are allergic to Tetralysal. For this very reason, you shouldn't take this medication. Its half life is 24 hours and it takes time 4-5 days to eliminate totally from your system. Due to that, you have still suffered from itching after stopping that medication 2 days ago. You have been suffering from the side effects of Tetralysal, not from herpes.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General & Family Physician
