Which of the following is a contraindication for OC spray use?

• A. Known severe chemical sensitivity or an active asthma condition.
• B. Ability to swim.
• C. Owning contact lenses.
• D. Having recently eaten spicy food.

Answer: (A)

OC spray can cause intense irritation of the eyes, airway, and mucous membranes. A known severe chemical sensitivity or an active asthma condition makes exposure potentially life-threatening because it can trigger a severe bronchospasm, airway swelling, and breathing difficulties. That’s why this is a contraindication: using OC spray in someone with chemical sensitivity or asthma could cause a dangerous reaction.

The other factors described don’t inherently raise the risk in the same way. Being able to swim, owning contact lenses, or having recently eaten spicy food do not predict a dangerous reaction to OC spray, so they aren’t contraindications.
