Sillicone allergy: Overview

Silicone allergy is a rare immune response to silicone, commonly used in medical devices and implants. This allergic reaction can manifest in various ways, depending on the individual and the type of silicone device involved.

In some cases, silicone allergy can cause complications with medical devices such as cochlear implants, pacemakers, and ventriculoperitoneal shunts. For instance, silicone allergy has been identified as a cause of cochlear implant extrusion, a condition where the implant is forced out of its original position [1]. Similarly, silicone allergy can mimic shunt infection, leading to complications with ventriculoperitoneal shunts [2].

Silicone allergy can sometimes lead to skin reactions. For example, allergic contact dermatitis, a type of skin inflammation, has been reported following breast augmentation with silicone implants [3]. Another skin reaction, contact urticaria, has been reported in response to the silicone rubber in gas masks [4].

Systemic reactions, including autoimmune diseases, can also be caused by silicone allergy. For instance, silicone breast implants have been associated with immune dysregulation and autoimmune diseases, with allergic reactions not being uncommon [5].

It's important to note that silicone allergy can be challenging to diagnose due to its rarity and the nonspecific nature of its symptoms. However, it can be identified through various tests, such as silicone allergy testing, detection of anti-silicone antibodies, and specific manufacturer's patch tests [1, 2, 6, 7].

Prevention of Sillicone Allergy

While there is no guaranteed way to prevent a silicone allergy, some steps can be taken to minimize the risk and manage the condition if it does occur.

Firstly, if you have a known allergy to silicone, it's crucial to inform your healthcare provider. This is particularly important if you're undergoing a procedure that may involve the use of silicone-based medical devices. In such cases, silicone alternatives can be explored. For instance, in cases of pacemaker implantation, custom-made silicone-free pacemaker components and silicone-free transvenous leads have been used successfully [7].
