1. Why am I using Varenicline Lupin?
Varenicline Lupin contains the active ingredient varenicline tartrate.
Varenicline Lupin is used to help adults stop smoking. It can help to reduce craving and withdrawal symptoms that may happen while you stop smoking.
People giving up smoking are often affected by nicotine withdrawal. Symptoms of nicotine withdrawal can include craving for tobacco, irritability, frustration, feeling angry, sleep problems, depressed mood, feeling anxious, difficulty concentrating, restlessness, decreased heart rate, increased appetite or weight gain. Not everybody is affected by symptoms of nicotine withdrawal.
Although it is not recommended that you smoke after your quit date, Varenicline Lupin will reduce your enjoyment of cigarettes if you do smoke while on treatment.
How Varenicline Lupin works
Varenicline Lupin 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. It is believed that Varenicline Lupin works by activating these receptors and blocking nicotine from attaching to them. Varenicline Lupin does not contain nicotine and it is not addictive.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
