2. "Do not wash the affected areas for at least 30 minutes after applying capsaicin."
3. "Discontinue the use of capsaicin if a burning or stinging sensation occurs."
4. "Capsaicin should only be used if oral analgesics have been ineffective."



Answer :

Final answer:

Capsaicin, a topical analgesic, should be applied without washing the affected areas for 30 minutes post-application. Discontinue its use if a burning or stinging sensation arises.


Explanation:

Capsaicin is a topical analgesic that binds to nociceptors sensitive to temperatures above 37°C, decreasing pain sensation. When using capsaicin, do not wash the affected areas for at least 30 minutes to allow absorption. If a burning or stinging sensation occurs, discontinue capsaicin use as it may indicate an adverse reaction.
