The Science of Nicotine Replacement Therapy (NRT)

Quitting smoking is a complex physiological challenge due to nicotine dependency. Clear nicotine transdermal patches (like NicoDerm CQ) deliver a steady stream of nicotine through the skin, helping to alleviate withdrawal symptoms.

The Step-Down Dosing Method

Nicotine patches use a structured step-down therapy program:

  • Step 1 (21 mg): Commenced for heavy smokers (more than 10 cigarettes a day) for the first 6 weeks.
  • Step 2 (14 mg): Designed to taper down dosage for weeks 7-8.
  • Step 3 (7 mg): The final step to complete cessation during weeks 9-10.

Skin Application Guidelines

Apply the patch to a dry, clean, and hairless area of the upper body. Rotate application sites daily to prevent localized skin irritation.
