You are extremely allergic to sulfa should you be concerned that your city water has sulfur in it?

It is unlikely that you need to be concerned about sulfur in your city's water causing an allergic reaction.

- Sulfur does not belong to the sulfa drug family used to treat bacterial infections.

- The suffix "sulfa" in sulfa drugs actually refers to the sulfonamide antibacterial group, which is a synthetic medication and chemically unrelated to sulfur.

- Thus, people who are allergic to sulfa drugs can safely consume water that contains sulfur without experiencing any allergic reactions.
