Allergic contact dermatitis involves skin inflammation that leads to redness, swelling and significant itchiness. After being exposed to tomatoes, a skin rash might arise in minutes or up to 48 hours.

The rash can range from minor to severe. In some cases, it might take several exposures before the rash could be identified. The reason for this is that the body is steadily building up antibodies to fight the allergen.

Management of a skin rash from tomatoes

If an individual develops allergic contact dermatitis after consuming tomatoes, the initial step is to cleanse the site that was exposed. After washing the area and eliminating any lingering residue, apply hydrocortisone cream. In some instances, the doctor might prescribe a corticosteroid cream for severe cases.

An effective test that confirms if an individual has tomato allergy is a patch test. The doctor will apply a patch on the skin that contains a small quantity of the allergen. This patch can remain on the skin for some time. The doctor will get rid of it to monitor the skin for the formation of a rash.

Preventive measures

Identifying and avoiding the source of contact dermatitis is the initial step in managing the skin rash. Once the individual has been diagnosed with contact dermatitis associated to tomatoes, it is vital to avoid consuming them.

Carefully check the ingredients on pre-packed foods and ask the server about the ingredients when eating in restaurants. It is vital to wear gloves if needed when handling tomatoes or tomato plants.
