If you are allergic to sulfa drugs

Rub on Relief does contain MSM. If you have a skin allergy to MSM it is not recommended to use Rub on Relief. Many people who are allergic to sulfa drugs, like Septra, Bactrim and Erythromycin, are typically not allergic to MSM in topical form.

We would recommend patch testing it on your skin to see if you have an adverse reaction. If no allergic symptoms are noted after 7 days of test application, you are safe to use it. If any itching, swelling or redness occurs during patch testing or normal application, please discontinue use and return for a full refund.

And in all cases, we suggest that you consult your physician before use as only they know your complete medical history and only then can answer you questions regarding your medical concerns.
