1. What Delstrigo is and what it is used for
What Delstrigo is
Delstrigo is used to treat HIV (‘human immunodeficiency virus’) infection. It belongs to a group of medicines called ‘antiretroviral medicines’.
Delstrigo contains the active substances:
What Delstrigo is used for
Delstrigo is used to treat HIV infection in people 18 years of age and older. HIV is the virus that causes AIDS (‘acquired immune deficiency syndrome’). You should not take Delstrigo if your doctor has told you that the virus causing your infection is resistant to any of the medicines in Delstrigo.
How Delstrigo works
Delstrigo works by preventing HIV from making more viruses in your body. This will help by:
2. What you need to know before you take Delstrigo
Do not take Delstrigo:
Do not take Delstrigo if the above applies to you. If you are not sure, talk to your doctor, pharmacist, or nurse before taking Delstrigo. See also the list in section “Other Medicines and Delstrigo”.
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before taking Delstrigo.
Passing HIV to others
HIV is spread by contact with blood or through sexual contact with a person with HIV. You can still pass on HIV when taking Delstrigo, although effective therapy lowers the risk. Talk to your doctor about what you can do to avoid infecting other people.
Worsening of hepatitis B infection
If you have both HIV and hepatitis B virus infections, your hepatitis B may get worse if you stop taking Delstrigo. You may require blood tests for several months after stopping treatment. Discuss your hepatitis B therapy with your doctor.
New or worsening kidney problems, including kidney failure
This can happen in some people who take Delstrigo. Your doctor will do blood tests to check your kidney function before and during treatment with Delstrigo.
Bone problems
This can happen in some people who take Delstrigo. Bone problems include bone pain, and bone softening or thinning (which may lead to fractures). Joint or muscle pain or muscle weakness may also occur. Your doctor may need to do additional tests to check your bones.
Immune reactivation syndrome
This can happen when you start taking any HIV medicine, including Delstrigo. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your doctor right away if you start having any new symptoms after starting your HIV medicine.
Autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you start taking medicines for the treatment of your HIV infection. Autoimmune disorders may occur many months after the start of treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness beginning in the hands and feet and moving up towards the trunk of the body, palpitations, tremor or hyperactivity, please inform your doctor immediately to seek necessary treatment.
Children and adolescents
Do not give this medicine to anybody aged less than 18 years. The use of Delstrigo in people aged less than 18 years has not yet been studied.
Other medicines and Delstrigo
Tell your doctor, pharmacist, or nurse if you are taking, have recently taken, or might take any other medicines. This is because other medicines may affect how Delstrigo works, and Delstrigo might affect the way some other medicines work.
There are some medicines you must not take with Delstrigo. See list under “Do not take Delstrigo” section.
Talk to your doctor before taking the following medicines with Delstrigo as your doctor may need to change the dose of your medicines:
If your doctor decides you should take these medicines with Delstrigo, your doctor will prescribe a 100 mg tablet of doravirine to be taken daily, approximately 12 hours after your dose of Delstrigo.
Your doctor may check your blood levels or monitor for side effects if you take the following medicines with Delstrigo:
Pregnancy and breast-feeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, talk to your doctor about the risks and benefits of taking Delstrigo. It is preferable to avoid the use of Delstrigo during pregnancy. This is because it has not been studied in pregnancy and it is not known if Delstrigo will harm your baby while you are pregnant.
Women with HIV should not breastfeed because HIV can be passed on to babies through breast milk. Talk with your doctor about the best way to feed your baby.
Driving and using machines
Use with caution when driving, riding a bicycle, or operating machines if you feel tired, dizzy, or sleepy after taking this medicine
Delstrigo tablets contains lactose
If you have been told by your doctor that you have an intolerance to lactose, talk to your doctor before taking this medicine.
3. How to take Delstrigo
Always take this medicine exactly as your doctor, pharmacist, or nurse has told you. Check with your doctor, pharmacist, or nurse if you are not sure. Delstrigo is a complete regimen taken as a single tablet for the treatment of HIV infection.
How much to take
The recommended dose is 1 tablet once a day. If you take certain medicines your doctor may need to change the amount of doravirine you take. See “Other medicines and Delstrigo” section for a list of medicines.
Taking this medicine
If you take more Delstrigo than you should
Do not take more than the recommended dose. If you accidentally take more, contact your doctor.
If you forget to take Delstrigo
If you stop taking Delstrigo
Do not run out of Delstrigo. Refill your prescription or talk to your doctor before your Delstrigo is all gone.
If you stop taking Delstrigo, your doctor will need to check your health often and do blood tests regularly for several months to check your HIV infection. If you have HIV infection and hepatitis B infection, it is especially important not to stop your Delstrigo treatment without talking to your doctor first. Some patients have had blood tests or symptoms indicating that their hepatitis has worsened after stopping lamivudine or tenofovir disoproxil (two of the three active substances of Delstrigo). If Delstrigo is stopped your doctor may recommend that you resume hepatitis B treatment. You may need blood tests to check how your liver is working for 4 months after stopping treatment. In some patients with advanced liver disease or cirrhosis, stopping treatment is not recommended as this may lead to worsening of your hepatitis, which may be life-threatening.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
