Patch strengths
Understanding Step 1, Step 2, and Step 3 patches.
Many patch systems use a step-down approach. The exact starting step depends on the specific product label and how much you currently smoke.
14mg patches
Often used after Step 1 in a tapering plan or as a starting point for some lighter smoking patterns, depending on the label.
7mg patches
Often the lowest common patch step and commonly used later in a step-down plan as directed.
2mg vs 4mg
Understanding 2mg and 4mg gum or lozenges.
Gum and lozenge strength is commonly guided by the product label and your smoking pattern. Many labels use timing after waking or smoking intensity to help determine strength.
2mg
Often used for lower nicotine needs.
2mg gum or lozenges may be appropriate for some lighter smoking patterns or people who do not smoke soon after waking, depending on the exact product directions.
4mg
Often used for higher nicotine needs.
4mg gum or lozenges may be appropriate for some heavier smoking patterns or people who smoke soon after waking, depending on the exact product directions.
Label
The product label is the deciding guide.
Do not guess strength based only on a web page. Read the package directions, warnings, and dosing instructions for the exact product you plan to use.

Strength FAQ
Common questions before choosing NRT strength.
These answers are designed to help you shop more confidently. They do not replace product labeling or medical advice.
How do I know what nicotine patch strength to start with?
Read the directions on the exact patch product you plan to use. Many patch labels guide the starting step based on how much you currently smoke. If you are unsure, ask a healthcare professional.
What is the difference between 21mg, 14mg, and 7mg patches?
These are common step-down patch strengths. 21mg is often the highest common step, 14mg is a middle step, and 7mg is often the lowest common step. The correct starting step depends on product directions and your smoking pattern.
How do I choose between 2mg and 4mg gum?
Use the product label. Many gum labels guide 2mg vs. 4mg selection based on how soon you smoke after waking or how much you smoke. Do not guess if you are unsure.
How do I choose between 2mg and 4mg lozenges?
Use the product label for the specific lozenge you are buying. Many lozenge products use smoking timing or intensity to help guide the starting strength.
Can I start with a lower strength to be safe?
Not always. Starting too low may not manage cravings well, while starting too high may increase unwanted effects. Use the product label and ask a healthcare professional if you are unsure.
Can I switch strengths later?
Some products are designed to step down or adjust over time, but you should follow the product directions. If your cravings are not controlled or you have side effects, ask a healthcare professional.
Can I combine patch with gum or lozenges?
Do not combine NRT products unless the product label allows it or a healthcare professional recommends it. Combining nicotine products can increase nicotine exposure.
What should I buy if I still do not know my strength?
Start with Find My Starting Point if you are unsure about format, or ask a healthcare professional if you are unsure about strength, medical conditions, or product safety.
