Porphyria can be serious. Were I in your place, I personally would stop the 6MP.
From the Mayo web site on drugs that can trigger symptoms:
Drugs (barbiturates and sulfonamide antibiotics are most often cited, but others such as tranquilizers, birth control pills and sedatives also may cause symptoms)
Mayo has an excellent patient information site for almost all conditions. If you want to read more about porphyria, here is the link.
Good luck, dear, and I hope you hear from your doctor soon.
