Anyone who received Botox at Rodrigo Beauty between May 1 and June 4 is urged to contact state or local health officials. Those experiencing symptoms should go to the nearest emergency department, health officials said.

At least 10 people who received procedures at Rodrigo Beauty, at 464 Granite Ave., are thought to have contracted iatrogenic botulism, a rare but life-threatening condition, the state Department of Public Health said in a statement Saturday.

State health officials are urging people who received cosmetic Botox injections recently at a Milton spa to come forward, after the location was tied to a “growing cluster” of botulism cases.

Rodrigo Beauty did not immediately return a request for comment Saturday night. It appeared the website for booking appointments had been taken down.

State health officials previously issued an advisory about four suspected cases on the South Shore, raising the tally of cases to six on Friday. They did not say at the time whether the individuals had received injections at the same location.

Use of botulinum toxin — commonly known by the popular brand name Botox — for cosmetic procedures is widely understood to be safe. The powerful toxin blocks the ability of the nervous system to activate muscles, helping to both soften and prevent wrinkles. Botox injections are the most common cosmetic procedure administered worldwide, with an estimated 3 million injections done annually.

Health officials stress that Botox and other cosmetic procedures should only be administered by licensed professionals in accredited medical settings.

Botulism results when the botulinum toxin circulates in the blood, causing a variety of paralytic symptoms. Those symptoms include double or blurred vision, drooping eyelids, slurred speech, difficulty swallowing, and difficulty breathing. Such symptoms are sometimes followed by muscle weaknesses, which can progress over the course of hours or days.

In November, a Stoughton woman was arrested and charged with selling counterfeit Botox injections out of Skin Beauté Med Spa in Easton and Randolph. Prosecutors said the woman has falsely posed as a nurse and had performed over a thousand injections with the counterfeit products.
