Apretude (Generic Cabotegravir): Complete Medication Guide
Key Takeaways
Generic cabotegravir is a long-acting HIV medication taken as an injection every two months.
It works by blocking an enzyme that allows HIV to multiply and spread in your body.
Common side effects include injection site reactions and mild headaches.
This medication is only for people with HIV who have already started treatment with other antiretroviral drugs.
Apretude offers convenience through less frequent dosing compared to daily pills.
Apretude (Generic Cabotegravir) Overview
Apretude is the brand name for generic cabotegravir, an injectable HIV medication that belongs to a drug class called integrase strand transfer inhibitors (INSTIs). Unlike daily pills you take by mouth, cabotegravir is given as an injection under the skin every two months after an initial loading period. This medication works by blocking an enzyme called integrase, which HIV uses to insert its genetic material into your immune cells. By stopping this process, the drug prevents the virus from multiplying and helps keep your viral load undetectable.
Cabotegravir is used as part of combination therapy for people with HIV who have already started treatment with other antiretroviral medications. It's designed for people whose HIV is suppressed and who want a more convenient dosing schedule. Understanding generic vs brand name drugs can help you see how generic cabotegravir offers the same effectiveness as brand-name Apretude at a lower cost.
This medication represents a significant advancement in HIV treatment by reducing the pill burden and helping people maintain consistent therapy. Your healthcare provider will determine if cabotegravir is the right choice based on your viral load, previous treatments, and overall health.
Side Effects
Most people tolerate cabotegravir well, though some experience mild to moderate side effects, particularly at the injection site.
Common Side Effects
Injection site reactions: Redness, swelling, bruising, or mild pain at the injection site that usually goes away within a few days.
Headaches: Mild to moderate headaches that typically resolve on their own or with over-the-counter pain relief.
Muscle or joint pain: Mild aches that may occur after injection but usually improve quickly.
Fatigue: Feeling tired or lacking energy, which is usually temporary.
Fever: A low-grade fever or chills that may occur shortly after injection.
Nausea: Mild stomach upset or nausea that generally resolves within hours or days.
Serious Side Effects
Severe allergic reactions: Though rare, severe rashes, swelling of the face or throat, or difficulty breathing require immediate medical attention.
Hypersensitivity reactions: Serious reactions affecting the liver or skin that can develop days to weeks after starting the medication.
Liver problems: Changes in liver enzymes or hepatitis symptoms including yellowing of skin or eyes.
Kidney issues: Problems with kidney function or changes in kidney tests.
Long-acting nature complications: Because this medication stays in your system for months, any serious side effects may take longer to resolve.
When to Seek Medical Attention
Contact your healthcare provider if you develop a rash, especially one with fever or swelling of face or lips. Seek immediate emergency care if you experience severe difficulty breathing, chest pain, or signs of severe allergic reaction.
If you notice yellowing of your skin or eyes, dark urine, unusual bruising, or signs of infection, reach out to your doctor. Most injection site reactions are mild and resolve on their own, but tell your healthcare team if you develop severe pain, swelling, or signs of infection at the injection site.

Important: Never skip or delay your scheduled injection without talking to your doctor first. If you miss your appointment, call your healthcare provider right away to reschedule. Do not stop taking cabotegravir on your own, as missing doses can allow HIV to develop resistance to the medication. Always keep your injection appointments to maintain consistent medication levels.
Drug Interactions
Cabotegravir can interact with other medications and substances. These interactions may change how the drug works or increase side effects. Always tell your healthcare provider about all medications, supplements, and herbs you take.
Dolutegravir and Other Integrase Inhibitors
Taking cabotegravir with other integrase inhibitors like dolutegravir may increase the risk of side effects or reduce effectiveness. Avoid combining these medications unless specifically directed by your doctor.
Rifampin (Tuberculosis Medication)
Rifampin significantly reduces cabotegravir levels in your blood, potentially making it less effective. If you need rifampin for TB, your doctor must adjust your treatment plan or use alternative medications.
Antacids Containing Magnesium or Aluminum
Antacids can reduce how much cabotegravir your body absorbs, making it less effective. Space antacids at least two hours away from your cabotegravir injection, or ask your doctor about alternatives.
St. John's Wort (Herbal Supplement)
This herbal supplement decreases cabotegravir levels significantly and may reduce its effectiveness. Avoid St. John's Wort while taking this medication without discussing it with your healthcare team.
Proton Pump Inhibitors (Acid Reflux Medications)
Medications like omeprazole may reduce cabotegravir absorption. Work with your doctor if you take these regularly to ensure your HIV medication remains effective.
Oral Contraceptives (Birth Control)
Some birth control pills may have reduced effectiveness when combined with certain antiretroviral regimens. Discuss contraception options with your healthcare provider to ensure adequate protection.

Cabotegravir requires a loading period where you receive two injections within four weeks to build up adequate levels in your bloodstream.
