Varenicline Tartrate at CanadaPharmacyOnline.com

The brand Chanix is currently unavailable (at this pharmacy).

Generic varenicline tartrate is sourced from manufacturers that meet applicable regulatory standards. The specific manufacturer of your dispensed medication may vary.

Important Information about Generic Varenicline Tartrate:

Generic varenicline tartrate contains the same active ingredient as the brand name Chantix. It is required to meet the same safety, effectiveness, and quality standards. This means it is designed to work in the same way as Chantix. While specific bioequivalence studies are conducted to ensure generic medications have comparable absorption rates and overall effects, individual responses to any medication can vary. Talk to your doctor or pharmacist if you have questions about using generic varenicline tartrate.

For more information about generic drug approval and bioequivalence, please visit Access to Generic Drugs in Canada | Canada.ca.

Dosage:

Generic varenicline tartrate is typically available in 4 Weeks Starter Kit and Continuation Pack at this pharmacy. Your doctor will determine the appropriate dose and duration of treatment based on your individual needs and smoking cessation plan. Chantix treatment usually starts with a titration period to minimize side effects.

Usage:

Chantix (varenicline tartrate) is a prescription medicine used to help adults quit smoking. It works by two main mechanisms: It partially stimulates nicotine receptors in the brain, reducing the severity of nicotine withdrawal symptoms and cravings, and it blocks nicotine from thoroughly stimulating these receptors, reducing the pleasurable effects of smoking if you do relapse.

Chantix is used as part of a comprehensive smoking cessation program that includes counselling and support. Your doctor will provide you with a quit date and a specific dosing schedule for Chantix. Treatment usually lasts for 12 weeks, with the possibility of an additional 12 weeks for successful quitters. For more information, refer to the product labeling information, https://www.accessdata.fda.gov/drugsatfda_docs/label/2016/021928s040lbl.pdf

Mechanism of Action:
Chantix (varenicline tartrate) is a partial nicotinic acetylcholine receptor (nAChR) agonist. It binds with high affinity and selectivity to the α4β2 nAChR, where it exerts agonist activity, with significantly lower intrinsic efficacy than nicotine, and antagonist activity in the presence of nicotine. This dual action is believed to contribute to its effectiveness in smoking cessation by reducing withdrawal symptoms and blocking the reinforcing effects of nicotine from cigarettes.

Use Chantix exactly as prescribed by your doctor. Follow the dosing schedule carefully, usually starting with a lower dose that is gradually increased. Swallow the tablets whole with water. You can take Chantix with or without food. It is essential to adhere to your quit date and continue taking Chantix for the entire duration of treatment recommended by your doctor, even if you have quit smoking. Follow the instructions in the patient information leaflet that comes with your medicine. It is essential to consult your doctor for personalized guidance and safe use.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before taking Chantix, it is essential to discuss all possible aspects with your doctor or pharmacist.

Contraindications:

This is not an exhaustive list of contraindications. It is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist before starting Chantix.

Chantix should not be used if:
• You are allergic to varenicline tartrate or other ingredients in Chantix.

Tell your doctor about all of your medical conditions, past and present, before starting Chantix. This is crucial because certain conditions can affect whether Chantix is right for you. These conditions may include, but are not limited to:
• Heart problems, including a history of heart attack or stroke
• Kidney problems, including end-stage renal disease
• Mental health conditions, including depression, anxiety, or schizophrenia
• Seizure disorders

Chantix may increase your risk of experiencing a cardiovascular event, including myocardial infarction, stroke, or cardiovascular death. You must tell your doctor about any possible risk factors for this, including past cardiovascular events such as a heart attack or stroke.

Driving or Operating Heavy Machinery:
Chantix may cause dizziness, drowsiness, or blurred vision. These side effects may interfere with your ability to safely operate a motor vehicle or use heavy machinery. Wait until these side effects subside before driving or using heavy machinery to reduce the risk of accidents.

Drug Interactions:

Before taking Chantix, it is essential to discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, refer to the official Chantix prescribing information: https://labeling.pfizer.com/ShowLabeling.aspx?format=PDF&id=557

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, and herbal supplements. Chantix may interact with other medicines, including but not limited to cimetidine (used to reduce stomach acid), insulin (dosage adjustments may be needed), nicotine replacement therapy (NRT), theophylline (used for breathing problems), or warfarin (a blood thinner).

Pregnancy and Breastfeeding:

Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding before taking Chantix. Limited data on the use of varenicline in pregnant women exist, and potential risks to the fetus cannot be ruled out. Chantix is not recommended during pregnancy unless the potential benefit outweighs the potential risk. It is not known if varenicline passes into breast milk, so breastfeeding is not recommended during treatment with Chantix.

Use in Children:

The safety and effectiveness of Chantix in children and adolescents under 18 years of age have not been established.

Frequently Asked Questions about Chantix at CanadaPharmacyOnline.com:

Why is Chantix more affordable in Canada than in the United States?

Prescription drug prices, including Chantix, are generally lower in Canada than in the US due to a combination of factors, primarily government price regulations, differing market dynamics, and other economic considerations.
