WARNING

Delstrigo is a medication used to treat HIV-1 infection. Like any medication, it carries certain risks and potential side effects. Some of the risks associated with taking Delstrigo include:

• Drug Interactions: Delstrigo can interact with other medications, including over-the-counter drugs and supplements. It’s essential to consult a healthcare provider before starting Delstrigo to avoid potential interactions.
• Allergic Reactions: Some individuals may experience allergic reactions to Delstrigo, which can manifest as rash, itching, swelling, dizziness, or difficulty breathing. Seek medical attention if you experience any of these symptoms.
• Liver Problems: Delstrigo can cause liver problems, including hepatotoxicity (liver damage). Symptoms may include yellowing of the skin or eyes, dark urine, abdominal pain, or unusual fatigue. Regular monitoring of liver function is necessary during Delstrigo treatment.
• Immune Reconstitution Syndrome: In some HIV-infected patients with severe immune deficiency, signs and symptoms of inflammation from previous infections may occur soon after starting antiretroviral therapy, including Delstrigo. This is known as immune reconstitution syndrome.
• Resistant Strains: As with any antiretroviral therapy, the development of drug-resistant HIV strains is possible if Delstrigo is not taken as prescribed or if the virus mutates. Adherence to the prescribed regimen is crucial to prevent the development of resistance.
• Bone Loss: Some HIV medications, including components of Delstrigo, have been associated with decreased bone density and an increased risk of fractures. Regular monitoring and supplementation with calcium and vitamin D may be necessary.
• Lactic Acidosis: In rare cases, Delstrigo can cause a condition called lactic acidosis, characterized by the buildup of lactic acid in the bloodstream. Symptoms may include weakness, unusual muscle pain, trouble breathing, stomach discomfort, nausea, vomiting, or feeling cold. Seek immediate medical attention if you experience these symptoms.

It’s important to discuss the risks and benefits of Delstrigo with a healthcare provider before starting treatment. Additionally, regular monitoring and communication with a healthcare team are essential to manage any potential risks effectively.

Why is this medication prescribed?

Delstrigo is a medication primarily prescribed to treat HIV-1 infection in adults who have never taken HIV medicine before. It’s a combination drug containing three active ingredients: doravirine, lamivudine, and tenofovir disoproxil fumarate. These medications work together to inhibit the replication of the HIV virus within the body, thereby helping to control the infection and reduce the risk of complications.

Doravirine belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs), which target a specific enzyme necessary for HIV replication. Lamivudine and tenofovir are nucleoside reverse transcriptase inhibitors (NRTIs), which work by interfering with another enzyme required for the virus to replicate its genetic material.

How should this medicine be used?

Delstrigo is usually taken orally once daily with or without food. It’s important to take it exactly as prescribed by your healthcare provider, as adherence to the prescribed regimen is crucial for the medication to be effective in controlling HIV infection. Missing doses or not following the prescribed schedule could reduce the drug’s effectiveness and increase the risk of developing drug resistance.

It’s also essential to discuss any other medications, supplements, or medical conditions you have with your healthcare provider before starting Delstrigo, as it can interact with certain drugs or conditions. Additionally, regular monitoring of HIV infection status and overall health is typically recommended while taking Delstrigo. If you have any questions or concerns about your treatment with Delstrigo, it’s best to consult with your healthcare provider for personalized advice and guidance.

Other uses for this medicine

Delstrigo is specifically approved for the treatment of HIV-1 infection in adults who have not previously received antiretroviral therapy (ART). It’s not indicated for other uses besides HIV treatment. However, there may be instances where healthcare providers prescribe medications off-label for conditions not specifically approved by regulatory agencies. This should only be done based on careful consideration of the patient’s individual circumstances and with appropriate monitoring.

What special precautions should I follow?

As for special precautions when taking Delstrigo, here are some key points to consider:

• Adherence: It’s crucial to take Delstrigo exactly as prescribed by your healthcare provider. Missing doses or not following the prescribed regimen can reduce the drug’s effectiveness and increase the risk of developing drug resistance.
• Drug Interactions: Delstrigo can interact with other medications, including over-the-counter drugs, prescription medications, and herbal supplements. Before starting Delstrigo, inform your healthcare provider about all medications and supplements you are taking to avoid potentially harmful interactions.
• Renal Function: Tenofovir, one of the components of Delstrigo, can affect kidney function. Your healthcare provider may monitor your kidney function regularly while you are taking this medication, especially if you have pre-existing kidney problems.
• Hepatic Function: Doravirine, another component of Delstrigo, may affect liver function. If you have liver disease or hepatitis, your healthcare provider may monitor your liver function regularly while you are taking Delstrigo.
• Pregnancy and Breastfeeding: The safety of Delstrigo during pregnancy and breastfeeding has not been established. If you are pregnant or planning to become pregnant, or if you are breastfeeding, discuss the risks and benefits of Delstrigo with your healthcare provider.
• Immune Reconstitution Syndrome: When starting ART, including Delstrigo, some patients may experience immune reconstitution syndrome, where the body’s immune system begins to recover and responds to previously hidden infections or conditions. This can sometimes result in the worsening of symptoms or the appearance of new symptoms. If you experience any unusual symptoms after starting Delstrigo, inform your healthcare provider.
• Side Effects: Like all medications, Delstrigo can cause side effects. Common side effects may include headache, diarrhea, nausea, fatigue, and abnormal dreams. If you experience severe or persistent side effects, contact your healthcare provider.

It’s important to communicate openly with your healthcare provider about any concerns or questions you have about taking Delstrigo. They can provide personalized guidance and support to help ensure the safe and effective use of this medication.

What special dietary instructions should I follow?

Special dietary instructions for Delstrigo are generally not required. You can take it with or without food. However, if you experience gastrointestinal discomfort, taking it with food may help alleviate these symptoms. Otherwise, there are no specific dietary restrictions associated with taking Delstrigo.

What should I do if I forget a dose?

If you forget to take a dose of Delstrigo, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you have any concerns or questions about missed doses, consult your healthcare provider or pharmacist for guidance.
