Drug Interactions between efavirenz and Juluca

Using efavirenz together with rilpivirine can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Additionally, efavirenz may cause central nervous system side effects such as drowsiness, confusion, hallucinations, abnormal behavior, delusions, and even psychosis-like behavior in some cases. Combining it with other medications that can also affect the nervous system such as rilpivirine may increase the risk and/or severity of these effects. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid driving, operating machinery, or engaging in potentially hazardous activities requiring mental alertness and motor coordination until you know how the medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Talk to your doctor before using efavirenz together with dolutegravir. Combining these medications may reduce the blood levels of dolutegravir, which may make the medication less effective in treating HIV infection. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition worsens or you develop new infections during treatment with these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
