What is Elvitegravir: Uses, Dosage, Side Effects and More

Elvitegravir is a prescription medication used to treat HIV infection as part of combination therapy. This antiviral drug belongs to a class called integrase strand transfer inhibitors, which work by blocking HIV from multiplying in your body.

If you've been diagnosed with HIV, your doctor might prescribe elvitegravir along with other HIV medications to help control the virus. Understanding how this medication works and what to expect can help you feel more confident about your treatment plan.

What is Elvitegravir?

Elvitegravir is an HIV medication that helps prevent the virus from replicating in your cells. It's always prescribed as part of a combination treatment, never alone, because using multiple HIV drugs together is much more effective than using just one.

You'll typically find elvitegravir in fixed-dose combination tablets that contain other HIV medications. The most common combination includes elvitegravir with cobicistat, emtricitabine, and tenofovir. This approach simplifies your daily routine by reducing the number of pills you need to take.

Think of elvitegravir as one important piece of a puzzle that works together with other medications to keep HIV under control. While it's a powerful tool in HIV treatment, it's not a cure for the virus.

What is Elvitegravir Used For?

Elvitegravir is specifically prescribed to treat HIV-1 infection in adults and children who weigh at least 35 kilograms (about 77 pounds). It's part of what doctors call highly active antiretroviral therapy, or HAART.

Your doctor will prescribe this medication to help reduce the amount of HIV in your blood to undetectable levels. When HIV levels become undetectable, it means the virus can't be transmitted to others through sexual contact, and your immune system can recover and stay strong.

This medication is typically prescribed for people who are starting HIV treatment for the first time, though it may also be used when switching from other HIV regimens. Your healthcare provider will determine if elvitegravir is right for your specific situation.

How Does Elvitegravir Work?

Elvitegravir works by blocking an enzyme called HIV integrase, which the virus needs to insert its genetic material into your healthy cells. When this enzyme is blocked, HIV can't complete its life cycle and make copies of itself.

This medication is considered moderately potent and works best when combined with other HIV drugs that attack the virus at different stages. The combination approach prevents HIV from developing resistance to any single medication.

Once you start taking elvitegravir as part of your combination therapy, you'll typically see your viral load decrease within a few weeks to months. Most people achieve undetectable viral loads within six months when they take their medications consistently.

How Should I Take Elvitegravir?

Take elvitegravir exactly as your doctor prescribes, usually once daily with food. Taking it with a meal helps your body absorb the medication properly and reduces the chance of stomach upset.

You can take this medication with any type of food, but avoid taking it on an empty stomach. If you're taking the combination tablet, swallow it whole with water or another beverage. Don't crush, chew, or break the tablet.

Try to take your medication at the same time each day to maintain steady levels in your bloodstream. Many people find it helpful to link taking their medication with a daily routine, like eating breakfast or brushing their teeth.

If you take antacids, calcium supplements, or iron supplements, space them at least two hours before or after taking elvitegravir. These products can interfere with how well your body absorbs the medication.

How Long Should I Take Elvitegravir For?

You'll need to take elvitegravir for as long as your doctor recommends, which is typically lifelong. HIV treatment is a long-term commitment, and stopping your medication can allow the virus to multiply again quickly.

Even when your viral load becomes undetectable, you'll continue taking your medications to keep it that way. Think of it like taking medication for high blood pressure - you keep taking it to maintain the benefit, not just until you feel better.

Your doctor will monitor your progress with regular blood tests to check your viral load and CD4 count. These tests help ensure your treatment is working effectively and that you're tolerating the medication well.

Never stop taking elvitegravir or change your dosing schedule without talking to your healthcare provider first. Even missing doses for a few days can lead to drug resistance and treatment failure.

What Are the Side Effects of Elvitegravir?

Most people tolerate elvitegravir well, but like all medications, it can cause side effects. The good news is that serious side effects are relatively uncommon, and many mild side effects improve as your body adjusts to the medication.

Here are the most common side effects you might experience:

• Nausea or stomach discomfort
• Diarrhea
• Headache
• Fatigue or tiredness
• Dizziness
• Trouble sleeping
• Strange or vivid dreams

These symptoms are usually mild and often improve within the first few weeks of treatment. Taking your medication with food can help reduce nausea and stomach upset.

Some people may experience more serious but less common side effects that require medical attention:

• Signs of kidney problems, such as changes in urination or swelling in your legs
• Bone pain or fractures
• Severe depression or mood changes
• Signs of liver problems, including yellowing of skin or eyes
• Severe allergic reactions with rash, swelling, or difficulty breathing

Contact your healthcare provider right away if you experience any of these serious side effects. They can help determine whether you need to adjust your treatment or seek immediate medical care.

Who Should Not Take Elvitegravir?

Elvitegravir isn't suitable for everyone, and your doctor will carefully review your medical history before prescribing it. You shouldn't take this medication if you're allergic to elvitegravir or any of the other ingredients in your combination tablet.

People with severe kidney disease may not be able to take elvitegravir, especially the combination that includes tenofovir. Your doctor will check your kidney function with blood tests before starting treatment and monitor it regularly.

If you have a history of bone problems, including osteoporosis or previous fractures, your doctor will weigh the benefits and risks carefully. Some HIV medications can affect bone density over time.

Certain medications can interact with elvitegravir, so tell your doctor about all prescription medications, over-the-counter drugs, and supplements you're taking. This includes herbal products, antacids, and vitamins.

Pregnant women can take elvitegravir, but your doctor will monitor you closely and may adjust your treatment plan. If you're trying to become pregnant or already pregnant, discuss your options with your healthcare provider.

Elvitegravir Brand Names

Elvitegravir is available in several brand-name combination medications, with Stribild being one of the most commonly prescribed. Stribild contains elvitegravir along with cobicistat, emtricitabine, and tenofovir disoproxil fumarate.

Another combination medication is Genvoya, which contains elvitegravir with cobicistat, emtricitabine, and tenofovir alafenamide. This newer formulation may be easier on your kidneys and bones compared to older versions.

Your doctor will choose the specific brand and combination based on your individual needs, kidney function, and other health factors. The active ingredient elvitegravir works the same way regardless of which brand you're prescribed.

Elvitegravir Alternatives

If elvitegravir isn't right for you, several other HIV medications can provide similar benefits. Other integrase inhibitors include dolutegravir, raltegravir, and bictegravir, each with their own advantages.

Your doctor might also consider combination medications that use different classes of HIV drugs, such as efavirenz-based regimens or boosted protease inhibitors. The choice depends on factors like your viral resistance pattern, kidney function, and personal preferences.

Some people prefer medications that can be taken without food, while others prioritize once-daily dosing. Your healthcare provider can help you weigh the pros and cons of different options to find the best fit for your lifestyle.

Is Elvitegravir Better Than Dolutegravir?

Both elvitegravir and dolutegravir are effective integrase inhibitors, but they have some important differences. Dolutegravir is generally considered to have a higher barrier to resistance, meaning it's harder for HIV to develop resistance to it.

Elvitegravir requires a booster medication called cobicistat to maintain effective levels in your blood, while dolutegravir doesn't need boosting. This means dolutegravir has fewer drug interactions and may be easier to take with other medications.

However, elvitegravir combinations are available as complete single-tablet regimens, which some people find more convenient. Your doctor will consider your specific situation, including your kidney function, other medications, and personal preferences when choosing between these options.

Both medications are highly effective when taken consistently, and the best choice is the one that works well for your body and fits into your daily routine.
