Warnings and precautions
Talk to your doctor or nurse before taking Esbriet:
- You may become more sensitive to sunlight (photosensitivity reaction) when taking Esbriet. Avoid the sun (including sunlamps) whilst taking Esbriet. Use a sunblock daily and cover your arms, legs and head to reduce exposure to sunlight.
- You should not take other medicines, such as tetracycline antibiotics (such as doxycycline), which may make you more sensitive to sunlight.
- You should tell your doctor if you suffer from mild to moderate liver problems.
- You should stop smoking before and during treatment with Esbriet. Cigarette smoking can reduce the effect of Esbriet.
- Esbriet may cause dizziness and tiredness. Be careful if you have to take part in activities where you have to be alert and co-ordinated.
- You should tell your doctor if you suffer from mild to moderate kidney problems.
- You will need a blood test before you start taking Esbriet and at monthly intervals for the first 6 months and then every 3 months thereafter whilst you are taking Esbriet to check whether your liver is working properly. It is important that you have these regular blood tests for as long as you are taking Esbriet.
3. How to take Esbriet
Do not share medicines prescribed for you with any other person. Always take Esbriet exactly as your doctor has instructed you. You should check with your doctor or pharmacist if you are unsure. Your medicine will usually be prescribed for you in increasing doses as follows:
- for the first 7 days: 267 mg (1 capsule), 3 times a day with food.
- from day 8 to 14: 534 mg (2 capsules), 3 times a day with food.
- from day 15 onwards: 801 mg (3 capsules), 3 times a day with food.
Swallow the capsules whole with a drink of water, during or after a meal to reduce the risk of side effects such as nausea (feeling sick) and dizziness. If symptoms continue, see your doctor.
Dose reduction due to side effects: Your doctor may reduce your dose if you suffer from side effects such as stomach problems, any skin reactions to sunlight or sun lamps, or significant changes to your liver enzymes.
If you take more Esbriet than you should
In the event of overdosage, consult your doctor or pharmacist. If neither is available, contact the nearest hospital or poison control centre, and take your medicine with you.
If you forget to take Esbriet
If you forget a dose take it as soon as you remember, but separate each dose by at least 3 hours. Do not take a double dose to make up for forgotten individual doses.
If you stop taking Esbriet
Do not stop taking Esbriet unless your doctor tells you to. If for any reason you have to stop taking Esbriet for more than 14 consecutive days, your doctor will restart your treatment with 267 mg (1 capsule) 3 times a day, gradually increasing this to 801 mg (3 capsules) 3 times a day. If you have any further questions on the use of Esbriet, ask your doctor or pharmacist.
