Example Prescription for Nicorette Gum (One Pack Per Day Smoker)
For a patient smoking one pack per day (≥20 cigarettes/day), prescribe Nicorette 4 mg gum, using 10-15 pieces per day initially, combined with a 21 mg nicotine patch for optimal cessation success. 1
Prescription Format
Nicorette (nicotine polacrilex) gum 4 mg
- Dispense: 200 pieces (approximately 2-week supply)
- Sig: Chew one piece slowly when urge to smoke occurs. Use "chew and park" method: chew 2-3 times, then park between gum and cheek for 15-30 minutes. Use 10-15 pieces per day initially. Maximum 24 pieces per day.
- Duration: 12 weeks minimum (may extend beyond 12 weeks if needed)
- Refills: 5
PLUS
Nicotine transdermal patch 21 mg/24 hours
- Dispense: 28 patches (4-week supply)
- Sig: Apply one patch to clean, dry, hairless skin on upper body or arm each morning. Rotate sites daily.
- Duration: Start with 21 mg for 4-6 weeks, then taper to 14 mg, then 7 mg
- Refills: 2
Dosing Rationale
The 4 mg gum is specifically indicated for patients who smoke ≥20 cigarettes per day or who smoke their first cigarette within 30 minutes of waking 2. One pack per day delivers approximately 20-40 mg of nicotine, requiring adequate replacement to prevent withdrawal 1.
- Each 4 mg piece delivers approximately 2 mg systemically (only half is absorbed) 1
- One piece = approximately 1-2 cigarettes worth of nicotine 1
- For a pack-a-day smoker, 10-15 pieces daily provides appropriate nicotine replacement
Critical Instructions for Patient
"Chew and Park" Technique (Essential for Efficacy)
- Chew the gum 2-3 times only until you taste pepper or feel tingling 1
- Park between gum and cheek for 15-30 minutes to allow buccal absorption 1
- Do NOT chew continuously like regular gum—this causes nicotine to be swallowed and wasted, leading to gastrointestinal symptoms and treatment failure 1
- Avoid food/beverages 15 minutes before and after use 2
Combination Therapy Advantage
Combination NRT (patch + gum) increases quit rates by 34% compared to single-form NRT 3, 4. The patch provides steady baseline nicotine levels while gum allows "top-up" dosing for breakthrough cravings 1.
Treatment Duration
- Minimum 12 weeks of full-dose therapy 1, 2
- Evidence suggests longer treatment periods (>12 weeks) may improve success rates 1
- Taper patch dose gradually: 21 mg → 14 mg → 7 mg, reducing by no more than 7 mg per week 1
- Gum can be continued as needed for cravings during and after patch taper
Common Pitfalls to Avoid
- Underdosing is the most common cause of NRT failure 1—one pack per day requires 4 mg gum, not 2 mg
- Improper gum technique leads to inadequate nicotine absorption and GI upset 1
- Premature discontinuation before 12 weeks reduces efficacy 1
- Using gum alone without patch in heavy smokers (≥10 cigarettes/day) is suboptimal 1
Safety Considerations
- NRT is safer than continued smoking, even in patients with cardiovascular disease 5, 6
- Common side effects: jaw soreness, hiccups, dyspepsia with gum 2, 6; skin irritation with patch 2
- Nicotine overdose is rare—smokers self-titrate effectively 1
- Symptoms of excess nicotine: nausea, headache, dizziness, tachycardia 1
Alternative for Lower Dependence
If the patient smokes their first cigarette >30 minutes after waking, consider 2 mg gum instead 2, 7. However, for one pack per day, 4 mg is generally appropriate 5, 3, 5.
Counseling Support
Provide brief cessation counseling (even 3-10 minutes) at each visit 2. Refer to state quit line (1-800-QUIT-NOW) for additional behavioral support, which enhances pharmacotherapy success 8.
