INJECTION SITE REACTION Receiving Cabenuva may cause a reaction at the injection site. This was a common side effect reported in studies of the drug. Injection site reactions may cause
symptoms such as: * warmth * swelling * bruising * redness or discoloration * itchiness * pain or tenderness * hardened lump WHAT MIGHT HELP If you have an injection site reaction during
Cabenuva treatment, these tips may help relieve your symptoms: * Apply ice to the site before and after the injection (for no longer than 15 minutes at a time), * Ask for a prescription
numbing cream to apply to the site before receiving the injection. * Take acetaminophen (Tylenol) to help relieve pain from the injection. * Avoid forcefully rubbing the area after an
injection. Injection site reactions will likely become less painful over time, but if the symptoms become worse or unmanageable, talk with your doctor or pharmacist. POSTINJECTION REACTION
Some people may have a postinjection reaction after receiving a Cabenuva injection. This was an uncommon side effect reported in studies of the drug. Most of the reactions reported in
studies happened within minutes of the injection and went away within minutes. After receiving your injection, you’ll be observed for about 10 minutes to check for a reaction. If one occurs,
it can be managed immediately. Postinjection reactions may cause symptoms such as: * difficulty breathing * abdominal cramps * feeling faint or lightheaded * sweating * feeling warm * pain
in the back and chest * feeling anxious * numbness in the mouth * skin rash * blood pressure changes WHAT MIGHT HELP Your doctor will have medications on hand to treat low blood pressure,
breathing difficulties, and pain in the event you experience a postinjection reaction during Cabenuva treatment. If you have concerns about the risk of a postinjection reaction, discuss this
with your doctor before getting the injection. ALLERGIC REACTION Like most drugs, Cabenuva can cause an allergic reaction in some people. Symptoms can be mild to serious and can include: *
skin rash * itchiness * flushing (temporary warmth, redness, or deepening of skin color) * swelling under your skin (usually in your eyelids, lips, hands, or feet) * swelling of your mouth,
tongue, or throat, which can make it hard to breathe After Cabenuva was approved, there have been rare reports of a severe allergic reaction known as drug reaction with eosinophilia and
systemic symptoms (DRESS) in people receiving the drug. DRESS may begin 2 to 8 weeks after starting Cabenuva treatment. Symptoms to look for include: * widespread body rash * swollen lymph
nodes * high fever * facial swelling There have also been rare reports of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). SJS is a rare and extremely serious condition
that causes your skin to come loose and detach. TEN is also a rare and serious skin condition that causes severe peeling and blistering which progresses quickly. It causes large raw areas
that may ooze or weep and can also affect the mucous membranes — including the mouth, throat, eyes, and genital region. DRESS, SJS, and TEN are all life threatening emergencies that require
immediate medical care. WHAT MIGHT HELP If you have mild symptoms of an allergic reaction, such as a mild rash, call your doctor right away. They may suggest a treatment to manage your
symptoms. Examples include: * an oral antihistamine, such as diphenhydramine (Benadryl) * a product you apply to your skin, such as hydrocortisone cream If your doctor confirms you’ve had a
mild allergic reaction to Cabenuva, they’ll decide if you should continue treatment. If you have symptoms of a severe allergic reaction, such as swelling, difficulty breathing, serious skin
rash, or fever, call 911 or your local emergency number right away. These symptoms could be life threatening and require immediate medical care. If your doctor confirms you’ve had a serious
allergic reaction to Cabenuva, they may have you switch to a different treatment. > KEEPING TRACK OF SIDE EFFECTS > During your Cabenuva treatment, consider taking notes on any side

and Cabenuva. However, Cabenuva can cause liver problems. Excessive alcohol use can also cause liver problems. So your risk of liver problems may be higher if you drink too much during your
Cabenuva treatment. If you have questions about consuming alcohol during Cabenuva treatment, talk with your doctor or pharmacist. PREGNANCY AND BREASTFEEDING WITH CABENUVA Before starting
Cabenuva treatment, talk with your doctor if you’re pregnant, breastfeeding, or planning to be either. PREGNANCY It’s not known whether it’s safe to receive Cabenuva while pregnant. This
drug’s use during pregnancy hasn’t been studied. However, a drug in the same class as cabotegravir (one of the active ingredients in Cabenuva) was shown to cause fetal harm when used in
early pregnancy. If you’re pregnant or planning to become pregnant, talk with your doctor about safe HIV treatment options. If you receive this drug while pregnant, consider signing up for
the Antiretroviral Pregnancy Registry. A pregnancy registry collects information about the safety of certain drugs when used during pregnancy. You can learn more on the website or by calling
800-258-4263. BREASTFEEDING It isn’t known whether Cabenuva passes into breast milk or is safe to use while breastfeeding. However, the Centers for Disease Control and Prevention (CDC)
recommends that you do not breastfeed if you have HIV. This is because HIV can pass through breast milk to a child. Talk with your doctor about other options for feeding your child. What to
ask your doctor Like most drugs, Cabenuva can cause side effects that range from mild to serious — but most are temporary and go away after a few days to weeks. If you have questions about
side effects Cabenuva can cause, talk with your doctor. Examples of questions to help get you started include: * Does Cabenuva cause weight gain? * How long do side effects of Cabenuva
usually last? * Do Cabenuva injections cause permanent muscle damage and long lasting pain? * Can I develop drug resistance to Cabenuva? To get information on different conditions and tips
