Baricitinib

Baricitinib is available as tablets (2 mg and 4 mg).

• The usual dose is 1 tablet (4 mg) ONCE DAILY for up to 14 days. Some people may need lower doses.
• Your doctor will decide what dose is right for you and how long you should take it for.
• You can take baricitinib with or without food.
• Swallow the tablet whole with a glass of water.
• If you have trouble swallowing tablets, they can be dissolved in some water so it’s easier to take.

Here are some things to know when you're taking baricitinib. Other things may be important as well, so ask your healthcare provider what you should know about.

• Females of child bearing age: If you could become pregnant, you should use effective contraception while being treated with baricitinib and for at least a week after stopping the treatment.
• Pregnancy: If you think you are pregnant or are planning a pregnancy, tell your doctor. At present, we know very little about the effects of baricitinib in pregnancy. 
• Other medicines: Use of live vaccines should be avoided immediately before and during treatment with baricitinib. Baricitinib may interact with some medications, herbal supplements and rongoā Māori, so check with your doctor or pharmacist before starting baclofen and before starting any new products.

Baricitinib can cause side effects, although not everyone gets them.
