Interactions between your drugs

Moderate

lamiVUDine chloramphenicol otic

Applies to: efavirenz / lamivudine / tenofovir disoproxil and chloramphenicol otic

After using chloramphenicol otic, some of the medication may be absorbed into the bloodstream and may increase the risk of side effects that affect your bone marrow function, resulting in low numbers of different types of blood cells. Using chloramphenicol otic together with lamiVUDine may further increase those risks. You may be more likely to develop anemia, bleeding problems or infections due to low blood cell counts. Although serious side effects are not very common with medications administered to the eyes, ears, or vagina because only limited amounts of the medication generally get absorbed into the bloodstream, they can sometimes occur. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need more frequent monitoring to safely use both medications. You should seek medical attention if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. 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.

Moderate

lamiVUDine efavirenz

Applies to: efavirenz / lamivudine / tenofovir disoproxil and efavirenz / lamivudine / tenofovir disoproxil

Efavirenz may cause liver problems, and using it with other medications that can also affect the liver such as lamiVUDine may increase that risk. You should avoid or limit the use of alcohol while being treated with these medications. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark colored urine, light colored stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Talk to your doctor or pharmacist if you have any questions or concerns. 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.

Drug and food interactions

Moderate

efavirenz food

Applies to: efavirenz / lamivudine / tenofovir disoproxil

Taking efavirenz with food increases the amount of medicine in your body, which may increase the frequency of side effects. You should take efavirenz once a day on an empty stomach, preferably at bedtime. Taking it at bedtime may make some side effects such as dizziness, trouble sleeping, drowsiness, trouble concentrating, and/or unusual dreams less bothersome. However, these symptoms may be more severe if efavirenz is used with alcohol or mood-altering (street) drugs. You should avoid driving or operating hazardous machinery until you know how the medication affects 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.
