What is Varenicline?

Varenicline is a prescription medication used as a smoking cessation aid. Its active compound is Varenicline tartrate, and it is formulated as an oral pill. The typical dosages available are 0.5mg and 1mg. Varenicline functions as a smoking cessation product and is classified as a partial agonist at the alpha-4 beta-2 nicotinic acetylcholine receptor. Varenicline is the generic version of medications containing the active compound Varenicline tartrate, marketed under brand names such as Champix and Chantix. Generic alternatives containing Varenicline tartrate may be available at lower cost.

How Varenicline Works

Varenicline's mechanism of action involves its interaction with nicotinic acetylcholine receptors in the brain, specifically the alpha-4 beta-2 subtype. These receptors are crucial in mediating the rewarding effects of nicotine and contributing to nicotine addiction. Varenicline acts as a partial agonist at these receptors. This means it binds to the receptors and activates them, but to a lesser degree than nicotine itself.

By partially activating these receptors, Varenicline achieves two key effects that aid in smoking cessation:

1. Reduces Cravings: It provides a degree of nicotine receptor stimulation, which helps to alleviate or lessen the intensity of nicotine cravings and the associated desire to smoke. This makes it easier for individuals to resist the urge to pick up a cigarette.

2. Blocks Nicotine's Effects: When a person does smoke, the nicotine from the cigarette binds to the alpha-4 beta-2 receptors. Because Varenicline is already partially bound to these receptors, it blocks nicotine from binding fully and producing its usual euphoric and reinforcing effects. This significantly diminishes the reward experienced from smoking, making the act less satisfying and helping to break the cycle of addiction.

The effect is a dual action that reduces the psychological and physical dependence on nicotine. Varenicline's metabolic profile indicates that it is primarily excreted unchanged by the kidneys, with a half-life of approximately 24 hours, allowing for once or twice daily dosing.

Conditions Treated with Varenicline

Varenicline is primarily approved for the treatment of nicotine dependence and to support smoking cessation in adults.

• Nicotine Dependence and Smoking Cessation: Varenicline is highly effective in helping individuals quit smoking by reducing both the cravings for nicotine and the pleasure derived from smoking. Clinical trials have demonstrated that it significantly increases the likelihood of sustained abstinence from smoking compared to placebo. It aids patients by mitigating the most challenging aspects of quitting, such as intense withdrawal symptoms and psychological dependence.

Is Varenicline the Right Medication for You?

Varenicline is generally recommended for adult smokers who are motivated to quit. It is particularly beneficial for individuals who have previously attempted to quit smoking without success or those who experience severe withdrawal symptoms. The medication offers a pharmacological approach to support the behavioral changes necessary for smoking cessation.

However, Varenicline is not suitable for everyone. It is contraindicated in individuals with known hypersensitivity to Varenicline or any of its inactive ingredients. Caution is also advised for patients with severe renal impairment, as dose adjustments may be necessary. Furthermore, individuals with a history of significant psychiatric disorders, such as depression or suicidal ideation, should discuss the potential risks and benefits with their healthcare provider, as rare but serious psychiatric side effects have been reported. Prescribing decisions are made on an individual basis after a thorough assessment of a patient's medical history and smoking cessation goals.

Use: Dosing, Missed Dose, Overdose

Dosing Instructions

Varenicline is typically initiated with a titration period to help the body adjust and minimise side effects.

• Days 1-7 (Weeks 1): 0.5mg once daily for the first three days, then 0.5mg twice daily for the remaining four days.
• Days 8-14 (Weeks 2): 1mg twice daily.
• For individuals who do not tolerate the 0.5mg twice daily dose: Maintain 0.5mg once daily for the first week and then increase to 0.5mg twice daily for the second week before proceeding to 1mg twice daily.
• Patients with severe renal impairment (creatinine clearance < 30 mL/min): The recommended dose is 0.5mg twice daily.

The target dose of 1mg twice daily is generally continued for a total of 12 weeks.

Missed Dose

If you miss a dose of Varenicline:

• If it has been less than 10 hours since your scheduled dose, take it as soon as you remember.
• If it has been more than 10 hours since your scheduled dose, skip the missed dose and take your next dose at the regular scheduled time. Do not take a double dose to make up for a missed one.

Overdose

If you suspect an overdose of Varenicline, seek immediate medical attention. Symptoms of overdose may include nausea, vomiting, and somnolence. Specific antidotes are not available, and treatment is symptomatic and supportive.

Practical Precautions

• Alcohol: Varenicline may increase the effects of alcohol. It is advisable to reduce or avoid alcohol consumption while taking this medication until you know how it affects you.
• Operating Machinery: Varenicline can impair your ability to drive or operate heavy machinery. Do not perform these activities until you know how the medication affects you, as it may cause drowsiness, dizziness, or affect your vision.
• Administration: Varenicline pills can be taken with or without food. It is generally recommended to take the morning dose after waking and the evening dose before bedtime.

Safety Information

⚠️ Who Should Not Take Varenicline

• Hypersensitivity: Individuals with a known hypersensitivity to Varenicline or any of its excipients should not use this medication. Allergic reactions, including rash and angioedema, have been reported.
• Severe Renal Impairment: While dose adjustments can be made, individuals with severe renal impairment should be closely monitored and may require a reduced dosage.
• Pregnancy and Breastfeeding: The safety of Varenicline in pregnant or breastfeeding women has not been fully established. It should only be used if the potential benefit justifies the potential risk to the foetus or infant. Consultation with a healthcare provider is essential.

Common Side Effects

Common side effects associated with Varenicline are generally mild to moderate and often resolve within a few weeks of treatment. These may include:

• Nausea
• Insomnia (difficulty sleeping)
• Abnormal dreams
• Headache
• Vomiting
• Flatulence (gas)
• Diarrhoea
• Constipation

These effects are typically dose-related and often diminish as your body adjusts to the medication. Taking Varenicline with food may help reduce nausea.

Serious Side Effects (Seek Immediate Medical Help)

While less common, serious side effects can occur. It is crucial to seek immediate medical attention if you experience any of the following:

• Neuropsychiatric Symptoms: Changes in behaviour or mood, including depression, suicidal thoughts, hostility, aggression, agitation, anxiety, and psychosis. If you experience any of these, contact your doctor immediately.
• Seizures: Varenicline may lower the seizure threshold. If you have a history of seizures or experience a seizure while taking Varenicline, discontinue use and seek medical help.
• Severe Skin Reactions: Rare but severe skin reactions, including Stevens-Johnson syndrome, have been reported. Symptoms may include blistering and peeling skin.
• Angioedema and Anaphylactic Reactions: Swelling of the face, lips, tongue, or throat, which may cause difficulty breathing or swallowing. Seek emergency assistance immediately.
• Cardiovascular Events: There have been reports of new or worsened cardiovascular events, including heart attack and stroke, particularly in patients with pre-existing cardiovascular disease. Discuss your cardiac history with your doctor.

Drug & Food Interactions

• Cimetidine: Concomitant use with cimetidine may increase Varenicline plasma concentrations, particularly in patients with renal impairment.
• Alcohol: As mentioned previously, Varenicline may increase the effects of alcohol. Reduce or avoid alcohol intake.
• Nicotine Replacement Therapy (NRT): If you are using NRT concurrently, be aware that Varenicline may reduce the effectiveness of NRT if dosed inappropriately or if the NRT dose is too high. This is typically managed by a healthcare provider if NRT is used alongside Varenicline.

It is imperative to inform your healthcare provider about all medications, supplements, and herbal products you are using to ensure no adverse interactions occur.

Off-Label and Investigational Uses of Varenicline

While Varenicline is primarily approved and widely recognised for smoking cessation, its mechanism of action has led to its investigation and occasional off-label use in other contexts.

• Nicotine Dependence in Specific Populations: Beyond general adult smoking cessation, Varenicline has been studied for its efficacy in specific populations, such as individuals with psychiatric comorbidities or those with other substance use disorders. Clinical studies suggest it can be effective in these groups when used under close medical supervision.

• Potential in Other Addictions: Due to its specific interaction with nicotinic receptors, there has been some research into Varenicline's potential role in managing other conditions involving similar neurochemical pathways, though these are largely investigational and not approved indications.

It is critical to understand that any use of Varenicline outside its approved indications is considered off-label. Efficacy and safety for these uses have not been formally evaluated or approved by regulatory bodies. Such treatments should only be undertaken under the explicit guidance and strict supervision of a qualified healthcare professional who can assess individual risks and benefits.
