Dovato vs Juluca
Introduction
For patients living with HIV (Human Immunodeficiency Virus), certain antiretroviral therapies can help manage the viral load and boost the immune system. Dovato and Juluca are two such prescribed medications for this purpose. They each contain different combinations of drugs but both have effects in managing HIV infection. Dovato is a combination of dolutegravir, an integrase strand transfer inhibitor (INSTI), and lamivudine, a nucleoside analogue reverse transcriptase inhibitor (NRTI). It works by blocking enzymes that the virus needs to multiply while also stopping HIV from copying itself, hence reducing its presence in the body. On the other hand, Juluca consists of rilpivirine, which is a non-nucleoside reverse transcriptase inhibitor (NNRTI) along with dolutegravir; these work together to prevent replication of the virus thereby decreasing its impact on one's health.
What is Dovato?
Dovato and Juluca are both antiretroviral medications used in the treatment of HIV, marking significant advancements from early options for managing this condition. Dovato is a combination of two drugs: dolutegravir and lamivudine. It was first approved by the FDA in 2019 as a complete regimen for treating HIV-1 infection in adults with no prior antiretroviral therapy history. This medication works by blocking the virus's ability to replicate, thus reducing its presence within an individual's system.
Juluca, on the other hand, combines dolutegravir with rilpivirine and received FDA approval earlier than Dovato, in 2017. Like Dovato, it inhibits viral replication but requires that the patient be virologically suppressed on a stable antiretroviral regimen before initiating treatment.
Both medications have been developed to minimize side effects associated with older classes of HIV treatments; however they still carry potential side effects including headaches and diarrhea. Importantly though, neither drug has a major influence on other physiological processes beyond their targeted action against HIV-1.
What conditions is Dovato approved to treat?
Dovato is approved for the treatment of different HIV-1 infections:
- New, previously untreated HIV-1 infection in adults
- Replacing the current antiretroviral regimen in individuals who are virologically suppressed on a stable antiretroviral regimen with no history of treatment failure and no known substitutions associated with resistance to either dolutegravir or lamivudine.
How does Dovato help with these illnesses?
Dovato works to manage HIV by combining two active ingredients, dolutegravir and lamivudine. Dolutegravir is an integrase inhibitor that prevents the virus from integrating its genetic material into the host's DNA, thus stopping it from replicating. Lamivudine belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs), which block another step in the HIV life cycle - reverse transcription of viral RNA into DNA. The combination of these two mechanisms makes Dovato effective for managing and reducing levels of HIV in patients' bodies.
Similarly, Juluca also uses a combination approach with dolutegravir and rilpivirine. Rilpivirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that blocks the same process as NRTIs but through a different mechanism.
While both medicines are designed for managing chronic HIV infection, they differ in their specific components aside from dolutegravir. It's crucial for individuals to work closely with healthcare professionals when determining which medication might be most suitable based on individual health conditions or possible drug interactions.
What is Juluca?
Juluca is a brand name for the combination of dolutegravir and rilpivirine, which are antiretroviral medicines used in the treatment of HIV. It works by blocking the activity of two types of enzymes that HIV needs to replicate itself, thus reducing viral load and increasing immune cell counts. Juluca was first approved by the FDA in 2017.
The distinctive nature of Juluca lies in its dual-drug regimen; while most traditional HIV treatments involve three or more drugs, Juluca simplifies this into a single daily pill containing only two active ingredients. This streamlined approach decreases potential drug interactions and side effects, making it an appealing option for individuals who have already achieved viral suppression with more complex regimens. Common side effects include headache and diarrhea but these are typically mild.
Its unique mechanism makes it particularly beneficial for managing patients with stable disease control on their current antiretroviral therapy looking to reduce long-term exposure to multiple drugs - unlike conventional multi-drug regimes often prescribed in such cases.
What conditions is Juluca approved to treat?
Juluca is a complete regimen for the treatment of HIV-1 infection, according to FDA guidelines. It has been approved for use in:
- Adult patients with no antiretroviral treatment history (as an initial regimen)
- Those who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no history of treatment failure and no known substitutions associated with resistance to the individual components of Juluca.
How does Juluca help with these illnesses?
Juluca is an antiretroviral medication used to treat HIV, a virus that attacks the immune system and can lead to acquired immunodeficiency syndrome (AIDS) if not addressed. It works by reducing the amount of HIV in the body, helping the immune system work better. A combination of two drugs- Dolutegravir and Rilpivirine- Juluca acts as a complete treatment regimen for HIV infection in adults who are virologically suppressed on their current regimen. This unique action helps reduce potential drug-drug interactions compared to other regimens and simplifies dosing schedules. Unlike Dovato, which also contains dolutegravir but partnered with lamivudine instead, Juluca may be more tolerable for certain patients or preferred when dealing with specific viral genetic characteristics or patient's comorbid conditions.
How effective are both Dovato and Juluca?
Both Dovato and Juluca are relatively new antiviral medications used to treat HIV-1 infection, having been approved by the FDA in 2019 and 2017 respectively. As they both target different steps of the viral replication process, they may be prescribed under different circumstances. The effectiveness of Dovato and Juluca was compared in a double-blind clinical trial that showed similar efficacy in suppressing viral load as well as presenting similar safety profiles.
A review carried out on Dovato demonstrated its efficiency at reducing viral loads from the first week of treatment, with a favorable side effect profile compared to many other antiretroviral therapies. It has shown high tolerability even among varying demographic groups including elderly populations and those with pre-existing health conditions. Being newer to market means there is ongoing research into its long-term effects; however, early studies indicate it could become a widely-used therapy due to its two-drug regimen simplifying treatment plans for patients.
Juluca's efficacy has also been confirmed through several studies where it performed better than placebo treatments while exhibiting comparable effectiveness against other common antiretrovirals. Although generally considered after or alongside other first-line treatments due to being newer on the market, significant research indicates that Juluca works effectively when co-prescribed along with another class of medication called nucleoside reverse transcriptase inhibitors (NRTIs). Its unique pharmacological properties make it an optimal choice for patients who do not respond well to NRTIs or need options with fewer drug interactions or side-effects.
At what dose is Dovato typically prescribed?
The recommended dose for both Dovato and Juluca in the treatment of HIV-1 infection is one tablet once daily. It's important to note that these medications should not be started if you are known to be allergic to any of their ingredients, or have certain medical conditions. Both drugs are designed as a complete regimen for treating HIV-1 infection; however, they shouldn't be used with other antiretroviral medications unless directed by your healthcare provider. Always consult with your doctor before starting any new medication regimen, as adjustment may be required based on individual response and tolerance.

Contraindications for Dovato and Juluca?
Dovato and Juluca, like most antiretroviral medications, can lead to a worsening of symptoms in some people. If you notice an increase in the severity or frequency of side effects, please seek immediate medical attention.
Both Dovato and Juluca should not be taken if you are taking or have been taking certain medicines due to the potential for serious drug interactions. These include drugs such as dofetilide (a heart rhythm medicine), rifampin (an antibiotic used for treating tuberculosis), St John's wort, amongst others. Always inform your healthcare provider about all the medications you are currently using; these incompatible drugs need sufficient time to clear from your system before starting therapy with Dovato or Juluca.
It is also important to note that neither Dovato nor Juluca should be used by patients who have had previous allergic reactions to any of their components. This information underlines why it is vital always to discuss your entire medical history with your doctor before commencing treatment with these HIV-1 medicines.
How much do Dovato and Juluca cost?
For the brand-name versions of these drugs:
- The price of 30 tablets of Dovato (dolutegravir and lamivudine) averages around $2,375, which works out to about $79 per day.
- The price for a month's supply (30 tablets) of Juluca (dolutegravir and rilpivirine) is roughly $3,150, equating to approximately $105 per day.
Thus, if you are on daily treatment with either drug as directed by your healthcare provider, Dovato is less expensive than Juluca on a cost-per-day basis. However, it's crucial to remember that cost should not be the primary consideration in determining which antiretroviral therapy is right for you.
Currently there are no generic alternatives available for either Dovato or Juluca. These medications are part of a class known as combination antiretroviral therapies used in the treatment of HIV infection. Decisions regarding which medication to use should primarily focus on clinical efficacy, patient preference and potential side effects rather than cost alone. If affordability issues arise when considering these options, patients can look into manufacturer assistance programs or other resources designed to help offset high prescription costs.
Popularity of Dovato and Juluca
Dovato, a combination of dolutegravir and lamivudine, was estimated to have been prescribed to around 150,000 people in the US in 2020. Dovato accounted for just over 9% of integrase inhibitor-based antiretroviral prescriptions in the US. This medication has seen an increase since its approval by the FDA in April 2019.
Juluca, which contains dolutegravir and rilpivirine, was prescribed to about 50,000 people in the USA during the same year. Juluca accounts for approximately 3% of integrase inhibitor-based antiretroviral prescriptions and has remained relatively steady since it got approved by FDA late November of 2017. Both drugs are part of modern HIV management strategies aiming at reducing pill burden and potential side effects.
Conclusion
Both Dovato (dolutegravir/lamivudine) and Juluca (dolutegravir/rilpivirine) are used in the treatment of HIV-1 infection, and their effectiveness has been demonstrated by numerous clinical studies. Each medication contains dolutegravir but they differ in their second component, with Dovato containing lamivudine and Juluca containing rilpivirine. This difference influences when each drug is prescribed: Dovato can be used as a first-line therapy for those who have not received antiretroviral treatment before or to replace the current antiretroviral regimen in those who are virologically suppressed, while Juluca is mainly intended for patients who have been on a stable antiretroviral regimen for at least six months without history of treatment failure.
Both medications come as single-tablet regimens which offer convenience to patients. They may require an adjustment period during which side effects could occur before diminishing over time.
The side effect profiles of both drugs are generally manageable; however side-effects depend on individual health conditions and reactions can vary among individuals. Commonly reported adverse reactions include headache, diarrhea (Dovato), depressive disorders, insomnia (Juluca). As with any medication treating serious illnesses such as HIV-1 infection, patients should closely monitor their symptoms especially when starting or changing treatments under medical supervision.
