Tivicay (dolutegravir) is a medication that's used as part of an antiretroviral (ARV) regimen for treating human immunodeficiency virus (HIV) infections. Some side effects can include trouble sleeping, tiredness, and headache, but they aren't very common with this medication. Tivicay (dolutegravir) comes as two different formulations: a tablet that you swallow whole and a tablet that you mix in water to make into a liquid solution. Tivicay (dolutegravir) is only available as a brand-name medication; there's no generic at this time.
Treatment of HIV infection in people aged 4 weeks and older
Tivicay (dolutegravir) is an integrase inhibitor. Integrase is an enzyme (protein) that HIV uses to insert its genetic information into your cells. Once inserted, HIV uses your cells to make more copies of itself. Tivicay (dolutegravir) works by blocking integrase, which then helps prevent HIV from spreading.

Not recommended for use if you have severe liver problems
Tivicay oral tablets are not the same as Tivicay PD tablets for oral suspension. If you're just starting or switching to a different formulation of Tivicay (dolutegravir), double check with your provider that the formulation, dose, and directions are appropriate for you.
Swallow Tivicay or Tivicay PD tablets whole. Don't chew, cut, or crush the tablet. For Tivicay PD tablets, if you need to take more than one tablet, swallow them one at a time so you don't choke on them.
If you're having trouble swallowing the tablet, ask your provider about using the Tivicay PD tablets to make a liquid solution that you can drink.
How to make a liquid solution from the Tivicay PD tablets: Mix the Tivicay PD tablets with 5 mL or 10 mL of water in the dosing cup provided. The amount of water you need will depend on the number of tablets for your dose. Swirl the mixture, and make sure there aren't any clumps. Then, drink the mixture within 30 minutes. You can add more water to the dosing cup, swirl, and swallow to make sure you've taken all the medication.
Make sure to get your routine blood tests done on time while you’re taking Tivicay (dolutegravir). This helps your provider make sure this medication is working for you and not causing side effects.
Take Tivicay (dolutegravir) 2 hours before or 6 hours after any antacids for heartburn (e.g., Tums) and supplements containing calcium, iron, magnesium, or aluminum. These medications can interfere with how your body absorbs Tivicay (dolutegravir) and cause it to not work as well at treating HIV. Taking Tivicay (dolutegravir) at a different time than these medications can help prevent this interaction from happening.
Let your provider or pharmacist know what medications you're taking or planning to take, including over-the-counter products and supplements. Tivicay (dolutegravir) can interact with many medications. These interactions can affect how well your medications work or how safe they are for you.
Tivicay (dolutegravir) can cause life-threatening allergic reactions. If you experience fever, rash, extreme tiredness, body aches, or trouble breathing, get medical attention right away.
Talk to your provider before stopping Tivicay (dolutegravir) or any of your HIV medications. Doing so can cause the virus to spread and become harder to treat.
Tivicay (dolutegravir) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factor: History of allergy to dolutegravir
Although rare, Tivicay (dolutegravir) can cause allergic reactions that are sometimes severe and life-threatening. Watch out for allergic reactions, such as severe rash with fever, general discomfort, muscle or joint pain, mouth sores, blisters, facial swelling, or trouble breathing. Stop taking Tivicay (dolutegravir) right away and get medical attention if you experience these symptoms.
If you have a serious allergic reaction, your provider will probably switch you to a different medication to treat HIV. Your provider might also check your liver function through blood work since severe allergic reactions can sometimes lead to liver injury.
Risk factors: Hepatitis B or C | Severe liver problems
Rarely, people who take medications that contain dolutegravir, such as Tivicay (dolutegravir), can experience serious liver problems. While liver injury can happen to anyone taking these medications, the risk for worsening liver problems might be higher if you also have hepatitis B or hepatitis C. Talk with your provider about your medical history before starting this medication so they can decide how you can safely take Tivicay (dolutegravir). Make sure to get blood tests done during treatment so your provider can check your liver health. If you experience symptoms of liver damage, such as nausea, vomiting, feeling weak, upper right stomach pain, yellowing of the skin or whites of the eyes, or dark urine, talk with your provider right away.
Taking combination ARV therapy, such as Tivicay (dolutegravir) with other HIV medications, can cause changes to your immune system called immune reconstitution syndrome. This medical condition happens when your immune system becomes more active after you start combination therapy. Your immune system begins to fight off different infections that it was too weak to fight off before you started treatment. In rare cases, your immune system might improve so much with treatment that it starts to attack normal cells in your body (autoimmune). You can develop immune reconstitution syndrome as early as during the first few weeks of treatment or many months later. Tell your healthcare provider right away if you start having any new symptoms, such as fever, pain, hair loss, bulging eyes, or sweating, after starting Tivicay (dolutegravir).
Some medications can interfere with how your body gets rid of Tivicay (dolutegravir) from your system. This can affect the amount of Tivicay (dolutegravir) in your body, how well it works, and the risk of side effects.
When taken with Tivicay (dolutegravir), certain medications can lower the amount of Tivicay (dolutegravir) in your body and cause it to not work as well at treating HIV. Because of this effect, avoid taking Tivicay (dolutegravir) with certain anti-seizure medications (e.g., carbamazepine (Tegretol), phenytoin (Dilantin)) or certain antibiotics (e.g., rifampin (Rifadin)). And make sure to take Tivicay (dolutegravir) 2 hours before or 6 hours after taking antacids like calcium carbonate (Tums) to prevent this interaction from happening.
Tivicay (dolutegravir) can also affect how your body absorbs other medications. For example, Tivicay (dolutegravir) can cause your body to absorb more dofetilide (Tikosyn), a heart rhythm medication. This can lead to irregular heartbeat that can be dangerous. Because of this risk, avoid taking Tivicay (dolutegravir) with dofetilide (Tikosyn).
Since there's a potential for interactions with Tivicay (dolutegravir) and various medications, tell your provider and pharmacist about all the medications you take or plan to take. They can make sure your medications are safe to take together.
Taking Tivicay (dolutegravir) during early pregnancy might raise the risk for birth defects called neural tube defects in babies. Because of this potential risk, if you're able to have a child, your provider will ask you to take a pregnancy test to check if it's safe for you to take Tivicay (dolutegravir). They'll also discuss with you about birth control options during your treatment with Tivicay (dolutegravir). It might be possible to take Tivicay (dolutegravir) in the second and third trimesters of pregnancy, but only if the benefit is greater than the risk of harm to the unborn baby. If you're pregnant or are planning to become pregnant, discuss your HIV treatment options with your provider.
