Methods: Five pharmaceutical vial closures (2 natural rubber and 3 synthetic) were coded, inserted onto vials containing phenol-saline-human serum albumin, and stored in an inverted position before use. Twelve volunteers with and 11 volunteers without LA underwent skin testing with solutions from each of the 5 vials, either those not punctured (0P) or those punctured 40 times with a 21-gauge needle 12 to 24 hours before testing (40P).
Send InquiryRisk of Latex Allergy from Pharmaceutical Vial Closures
Most pharmaceutical vial closures do not contain natural rubber latex. A recent attempt to quantify the prevalence of natural rubber latex in stoppers determined that 78% of pharmaceutical products marketed in the United States contain no latex. 2 Therefore, only a minority of pharmaceutical products place patients at risk for latex allergic reactions.

Silicone is used in many products and it is frequently found in pharmaceutical products. When it is used as a lubricant for rubber stoppers and plungers, it very easily “sloughs off” and ends up in the product. Silicone can interact with protein based drugs or active ingredients producing particles or residue.

Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Thailand and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex
