The drug I am going to introduce is Champix, which contains 0.5mg Varenicline Tartrate. Champix is a drug for smoking cessation, to help adults stop smoking. Since I was 16, my ambition is to be a pharmacist. Why pharmacist? Hmm, my dad is a heavy smoker and he smokes everyday. Yes, EVERYDAY. Therefore, I am ambitious enough to be a pharmacist and makes my dad a better life and of cause, * Make him to quit smoking* !
Champix, it can help to reduce craving and withdrawal symptoms that happen while you give up smoking. People giving up smoking are often affected by nicotine withdrawal. Symptoms of nicotine withdrawal can include craving for tobacco, irritability, frustration, feeling hungry, sleep problems, depressed mood, feeling anxious, difficulty in concentrating, restlessness, decreased heart rate, increased appetite, or weight gain. Not everybody is affected by some or all of the symptoms of nicotine withdrawal. Although it is not recommended that you smoke after the first one to two weeks of treatment, if you smoke while you are taking Champix it will reduce your enjoyment of cigarettes.
Champix works by blocking the effects of nicotine in your body. There are receptors for nicotine in the
brain. When cigarette smoke is inhaled, nicotine attaches to these receptors. This sends a message to a different part of the brain to release a chemical called dopamine. Dopamine gives a feeling of pleasure which
only lasts for a short time. The body wants to repeat this feeling reinforcing the need to keep
smoking. Based on research, it is believed that Champix works by activating these receptors and
blockinng nicotine from attaching to them.
The usual dosage instruction:
| Days 1 - 3 Take one white tablet once a day |
| Days 4 - 7 Take one white tablet in the morning and one in the evening |
| Weeks 2 - 4 Take one light blue tablet in the morning and one in the evening. Your first box of Champix will cover your first four weeks of treatment. You will need to visit your doctor before the end of the fourth week that you take Champix for a check-up and for a new prescription. At this appointment, your doctor will check your progress and give you a new prescription for the tablets you need to complete the remaining 8 weeks of treatment. |
| Weeks 5 - 12 Take one light blue tablet in the morning and one in the evening. After 12 weeks of treatment, if you have stopped smoking, your doctor may recommend another 12 weeks of treatment with Champix. This may increase your chances of stopping smoking long term. For this course, take one light blue 1 mg tablet in the morning and one in the evening. If you do not stop smoking during the first 12 weeks of treatment or if you start smoking again after treatment, you can make another attempt at stopping smoking. However, before you make another attempt, you should try to understand the reasons why your attempt to stop smoking failed, so that your next attempt has a better chance of success. |

Pay special attention to...
You and your family or carer need
to pay special attention to your
mood, behaviour and thinking
while you are taking Champix.
Some people have reported changes
in behaviour, thinking or mood when
they start taking Champix. These
may include depression, anxiety,
agitation, feelings of aggression,
mood swings, seeing, hearing or
sensing things that are not there,
thoughts of self-harm or self-harm.
Worsening of these symptoms has
also been reported in people who
already had mental health problems.
It is not known whether these are
related to Champix. It is known that
mood changes can be due to the
effects of stopping smoking, with or
without treatment.
Stop taking Champix and tell your
doctor immediately if you or your
family/carer notice any changes in
your behaviour or thinking, if you
become agitated or depressed, or
have thoughts of self-harm.
