Buy Varenicline tablets online to stop smoking

Varenicline, pronounced var-EN-i-kleen, is a stop-smoking treatment and is available to request on prescription from Oxford Online Pharmacy.

Varenicline tablets, which used to be available under the brand name Champix, contain the active ingredient Varenicline, a medicine used for smoking cessation. Varenicline does not contain nicotine.

Varenicline is used by adults who struggle to stop smoking and for those who have struggled to stop with nicotine replacement such as gum and patches.

According to the NHS, Varenicline Champix tablets are the most effective medicine for helping people stop smoking. [1]

Other studies also back the Varenicline NHS findings, such as a 2013 study comparing the effectiveness of NRT and Varenicline on smokers, research suggests that Varenicline tablets are superior to other stop-smoking methods.[2] Another study reports that up to 45.5% of people stopped smoking with Varenicline treatment compared to 33% of those using nicotine replacement therapy.[5]

How does Varenicline work?

Varenicline UK is a prescription-only medicine used to treat nicotine addiction and cravings.

The Varenicline drug can help you stop smoking in the following ways; 

  1. Stops cravings and withdrawal symptoms, such as bad moods associated with stopping smoking
     
  2. Reduces the enjoyment if you smoke cigarettes during treatment

How to stop smoking with Varenicline tablets?

Stopping smoking with Varenicline is most effective when you are motivated to stop, there is additional support and resources to help with this and more information on the NHS Stop Smoking page.

Before beginning your Varenicline treatment, we suggest you choose a ‘quit date’ in the second week (between days 8 and 14) for when you will stop smoking. 

If you're unable or unwilling to set a quit date within 2 weeks, choose a target quit date that you are comfortable with within 5 weeks of starting the treatment. Be sure to note this date on the pack as a reminder.

How to use Varenicline (Generic Champix)

You must always take Varenicline as directed by your prescribing doctor. If you are unsure of anything, get in touch and a member of our dedicated healthcare team will be happy to help. 

These tablets can be taken with or without food and should be swallowed whole with a glass of water. 

Varenicline dosing schedule 

Varenicline comes in two forms: a white tablet (0.5mg) and a light blue tablet (1mg). You would typically start with the white tablets and then proceed to the blue tablets.

Below, you can find the usual Varenacline tablet dosage chart: 

Week 1

Dose

Days 1-3 (Starter pack)

Take one (White) 0.5mg tablet daily

Days 4-7 (Starter pack)

Take one (White) 0.5mg tablet twice daily, once in the morning and once in the evening, at the same time each day

Days 8-14 (Continuation pack)

Week 3- 12

 

Day 15 - end of treatment (Continuation pack)

Towards the end of your treatment with Varenicline tablets, your doctor might suggest doing another 12 weeks of treatment with Varenicline 1mg tablets, twice daily to prevent returning to smoking. [4]

If you forget to take a dose of Varenicline, do so as soon as possible. However, if it's nearly time for your next dose, wait and take your next dose at the scheduled time.
