Consumer Information

This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.

What the medication is used for

APO-VARENICLINE is a prescription medicine which is used in combination with supportive counselling to help motivated adults stop smoking.

What it does

APO-VARENICLINE can help to relieve the craving and withdrawal symptoms associated with stopping smoking. APO-VARENICLINE does not contain nicotine, but it has been shown to affect the nicotine receptor in the brain that is thought to be most related to smoking addiction. APOVARENICLINE can affect this receptor in two opposite ways: it acts like a weaker version of nicotine, and also blocks nicotine from getting to the receptor because it binds more tightly. Although it is thought that this may be, in part, how APO-VARENICLINE works, it is not known exactly how the drug works in people.

When it should not be used

Do not take APO-VARENICLINE if you:

  • are allergic (hypersensitive) to varenicline tartrate or any of the other ingredients of APO-VARENICLINE (see list below of non-medicinal ingredients).
  • are using nicotine replacement therapy, such as patches, gum or inhaler. The combination of APOVARENICLINE and nicotine replacement therapy is not expected to improve your chances of quitting, and may result in more side effects than with APOVARENICLINE alone.
What the medicinal ingredient is

Varenicline tartrate.

What the non-medicinal ingredients are

The nonmedicinal ingredients are anhydrous dibasic calcium phosphate, magnesium stearate and microcrystalline cellulose. The film-coating contains hydroxypropyl cellulose, hydroxypropyl methylcellulose, titanium dioxide and triacetin. The 1 mg tablet also contains indigotine aluminum lake 12% to 14% as a colouring agent.

What dosage form it comes in

APO-VARENICLINE is available as film-coated tablets. The 0.5 mg tablets are white and the 1 mg tablets are blue.

Warnings and precautions

BEFORE you use APO-VARENICLINE talk to your healthcare provider if you:

  • have experienced depression or any other mental health problems. Your healthcare provider will monitor you for new or worsened emotional or behavioral problems during treatment with APO-VARENICLINE.
  • have any problems with your kidneys, as you may need a lower dose of APO-VARENICLINE.
  • have heart or blood vessel (cardiovascular) problems.
  • have a history of seizures.
  • have any other medical conditions.
  • are pregnant, are breastfeeding or plan to become pregnant (see “Pregnancy” and “Breastfeeding” below).
  • have diabetes. APO-VARENICLINE can potentially affect your blood sugar regulation, and you may need to monitor your blood sugar more often. If you notice changes, discuss this with your healthcare provider.

The effects of changes in your body resulting from stopping smoking, with or without treatment with APOVARENICLINE, may alter the way other drugs work. Tell your healthcare provider about all your other medicines, including prescription and nonprescription medicines, vitamins and herbal supplements. Especially, tell your healthcare provider if you take:

  • Insulin
  • Asthma medicines (theophylline)
  • Blood thinner (warfarin)

as an adjustment of the dose of these medicines may be necessary once you are smoke-free.

Mental Health Symptoms
See “What is the most important information I should know about APO-VARENICLINE?”

Pregnancy
Talk to your healthcare provider if you are pregnant or planning to become pregnant.

You should not take APO-VARENICLINE while you are pregnant. It is unknown if APO-VARENICLINE will harm your unborn baby.

It is best to stop smoking before you get pregnant.

Breastfeeding You should ask your healthcare provider for advice before taking any medication, including APO-VARENICLINE, if you are breastfeeding, as the medicine may pass into breast milk.

APO-VARENICLINE is not recommended for use in children under 18 years of age.

Accidental Injury, including while Driving, Operating Machinery
Do not engage in potentially hazardous tasks, such as driving a car or operating dangerous machines, until you know how APO-VARENICLINE may affect you. In some cases, people have reported sleepiness, dizziness, blackouts, seizures or difficulty concentrating while driving.

Seizures
Tell your healthcare provider if you have experienced seizures or have epilepsy before you start APO-VARENICLINE treatment. Some people have reported seizures while taking varenicline, both with and without a history of seizures.

Heart or Stroke Events
New or worse heart or blood vessel (cardiovascular) problems have been reported in people taking varenicline, primarily in those who already have cardiovascular problems. From the information available to date, it is not possible to determine whether APO-VARENICLINE increases the risk of heart or stroke events.

Tell your healthcare provider if you have any changes in cardiovascular symptoms during treatment with APOVARENICLINE. Get emergency medical help right away if you have symptoms of a heart attack, including any of the following:

  • Chest discomfort (uncomfortable pressure, squeezing, fullness or pain) that lasts more than a few minutes, or that goes away and comes back
  • Pain or discomfort in one or both arms, back, neck, jaw or stomach.
  • Shortness of breath, sweating, nausea, vomiting, or feeling lightheaded associated with chest discomfort.

Get emergency medical help right away if you have symptoms of a stroke, including any of the following:

  • Weakness - Sudden loss of strength or sudden numbness in the face, arm or leg even if temporary.
  • Trouble speaking - Sudden difficulty speaking or understanding or sudden confusion, even if temporary.
  • Vision problems - Sudden trouble with vision, even if temporary.
  • Headache - Sudden severe and unusual headache.
  • Dizziness - Sudden loss of balance, especially with any of the above signs.

Sleepwalking Sleepwalking has been reported in patients taking APOVARENICLINE, and may sometimes lead to behaviour that is harmful to you or other people or property. Stop taking APOVARENICLINE and tell your healthcare provider if you start sleepwalking.

Interactions with this medication

Drinking alcohol during treatment with APOVARENICLINE may increase the risk of mental health symptoms.
Reported experiences include:

  • unusual or sometimes aggressive behavior;
  • more intoxicated than expected from the amount of alcohol;
  • no memory of things that have happened.

Use of APO-VARENICLINE with other therapies for smoking-cessation:
The safety and benefits of taking APO-VARENICLINE in combination with other medicines for stopping smoking have not been studied. Taking APO-VARENICLINE in combination with other smoking-cessation therapies (e.g., nicotine replacement therapy) is therefore not recommended. Using APO-VARENICLINE in combination with nicotine replacement therapies (e.g., patch gum or inhaler) is not likely to increase your chances of quitting smoking, and it may result in more side effects than with APO-VARENICLINE alone.

Proper use of this medication

You are more likely to stop smoking if you are motivated to stop. Your healthcare provider can provide advice, support and sources of further information to help ensure your attempt to stop smoking is successful.

To increase the chances of success, APO-VARENICLINE should be used in combination with supportive counselling as recommended by your healthcare provider. Varenicline was used in combination with supportive counselling in the clinical trials. At any time, you can also call government-funded tollfree provincial Quit Lines, to speak to a knowledgeable and supportive specialist; these phone numbers are available on the Health Canada website.

Always take APO-VARENICLINE exactly as your healthcare provider has told you. You should check with your healthcare provider if you are not sure.

REMEMBER: This medication has been prescribed specifically for you. Do not give it to anyone else.

Setting Your Quit Date:

Starting treatment before your quit date lets APOVARENICLINE build up in your body. You can keep smoking until your quit date.

There are three ways to set your quit date when using APOVARENICLINE. Talk to your healthcare provider about which way is best for you:

  • Fixed quit approach: Set a quit date when you will stop smoking. Start taking APO-VARENICLINE 8 to 14 days (1 to 2 weeks) before your quit date. You should take APO-VARENICLINE for 12 weeks. After 12 weeks of treatment, your healthcare provider may recommend an additional 12 weeks of treatment.

Or

  • Flexible quit approach: Start taking APOVARENICLINE, then quit smoking between Day 8 and Day 35 after the start of your treatment (i.e. between Weeks 2 and 5). You should take APOVARENICLINE for 12 weeks. After 12 weeks of treatment, your healthcare provider may recommend an additional 12 weeks of treatment.

Or

  • Gradual quit approach: Start taking APOVARENICLINE and reduce smoking with a goal to quit smoking by end of 12 weeks of treatment. For example, reduce smoking by half by the 4th week, another half by the 8th week (down to 25%) and then quit by the end of the 12th week. You may quit any time before the end of 12 weeks of treatment, if you are able to. Continue treatment for an additional 12 weeks for a total of 24 weeks.

Write down, and keep in a visible or convenient place (for example on the fridge or on the APO-VARENICLINE pack), the date that you started APO- VARENICLINE, your quit date, and the date to stop taking APO-VARENICLINE.

Make sure that you try to stop smoking on your quit date. If you slip-up and smoke after that target date, keep trying. Some people need a few weeks on APO-VARENICLINE for it to work best.

Dosing Options:

APO-VARENICLINE should be taken after eating and with a full glass of water.

Regardless of which dose is prescribed, the first week on APO-VARENICLINE is the same, and is described in the following table:

Week 1 Dosing Schedule:

Day Dose
Day 1 to 3 Take one white APO-VARENICLINE 0.5 mg tablet once a day
Day 4 to 7 Take one white APO-VARENICLINE 0.5 mg tablet twice a day, once in the morning and once in the evening, at about the same time each day.

After the first week, your healthcare provider may recommend to stay at 0.5 mg twice a day (OPTION 1) or go up to 1 mg twice a day (OPTION 2).

Week 2 (day 8) to the end of treatment

OPTION 1: Continue on 0.5 mg twice a day

Day Dose
Day 8 - end of treatment 0.5 mg twice a day:
Continue to take one white APOVARENICLINE 0.5 mg pill in the morning, and one in the evening, at about the same time each day

Or

Day Dose
Day 8 - end of treatment 1 mg twice a day:
Take one light blue APOVARENICLINE 1 mg pill in the morning, and one in the evening, at about the same time each day.

The maximum dose of APO-VARENICLINE is 1 mg twice a day.

Based on the limited data available, the two doses do not appear different in terms of either quit rates, or rates of serious mental health side effects (your healthcare provider can provide more information).

Discussion with your healthcare provider is important in order to choose the dose that is best for you.

If needed, the dose can be changed depending on how well you tolerate APO-VARENICLINE and how effective your healthcare provider and you consider it is in helping you quit smoking. Your healthcare provider will help decide what dose is right for you.

Your healthcare provider may recommend to gradually lower the dose at the end of the treatment period rather than stopping abruptly

Can I smoke while taking APO-VARENICLINE?
You can keep smoking prior to your quit date.

Smoking after your quit date will reduce your chance of breaking your smoking addiction.

Some people have reported a change in the taste of cigarettes after starting APO-VARENICLINE.

Overdose

If you think you have taken too much APO-VARENICLINE, contact your healthcare professional, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

Missed Dose

Do not take a double dose to make up for a forgotten tablet. It is important that you take APO-VARENICLINE regularly at the same time each day. If you forget to take a dose, take it as soon as you remember, as long as it is within a few hours of the missed dose. If it has been longer than a few hours since the missed dose, or if you do not remember whether you took a dose or not, then skip that dose, and wait to take the next dose at the correct time.

If you have any further questions on the use of this product, ask your healthcare provider.
