What is paroxetine?
Paroxetine is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). Paroxetine is used to treat a number of mental health conditions including depression, obsessive-compulsive disorder (OCD), panic attacks, anxiety or post-traumatic stress disorder (PTSD).
We don't know for certain, but researchers think that SSRIs work by increasing the activity of serotonin which is thought to improve mood, emotion and sleep. Read more about SSRIs.
Dose
In New Zealand paroxetine is available as tablets (20 mg)
- The dose of paroxetine will be different for different people and depends on the condition being treated.
- Your doctor will usually start you on a low dose and if needed, will increase your dose slowly. This allows your body to get used to the medicine and reduces the chance of side effects.
- Always take your paroxetine exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much paroxetine to take, how often to take it, and any special instructions.
How to take paroxetine
- Take paroxetine once a day, in the morning, after breakfast. Take your dose at the same time each day. It is best to take paroxetine with food.
- Missed dose: If you forget to take your dose, take it as soon as you remember. But if it is nearly time for your next dose, just take it at the right time. Don't take double the dose.
- Keep taking paroxetine every day. It may take 4 to 6 weeks before you notice the full benefits of paroxetine and you should start to feel better after 1 to 2 weeks. Some people notice side effects in the first few weeks before they start to feel better. Paroxetine is often needed for at least a few months. Your doctor will discuss with you how long to take it for; this depends on what you are taking it for, and how well it is working.
- If you think paroxetine is not working for you. Do not stop taking it suddenly; talk to your doctor or nurse before stopping. It is usually best to stop taking paroxetine very slowly to avoid side effects.
Things to consider while you are taking paroxetine
- Limit alcohol intake while you are taking paroxetine. Alcohol can increase your chance of side effects such as drowsiness and reduced concentration.
- Avoid driving and doing other tasks where you need to be alert until you know how this medicine affects you.
- Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
- Paroxetine can interact with some medicines (including anticoagulants and anti-inflammatories such as ibuprofen), herbal supplements (such as St John's Wort), and recreational drugs, so check with your doctor or pharmacist before starting paroxetine and before starting any new products.
- If you have diabetes, you may need to check your blood glucose more often because paroxetine can affect the levels of glucose in your blood.
Possible side effects
Like all medicines, paroxetine can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.
