Patient monitoring

• Monitor renal function tests.
• Be aware that immune reconstitution syndrome has occurred in patients receiving drug with combination antiretroviral therapy. During initial phase of therapy, patient whose immune system responds may develop inflammatory response to indolent or residual opportunistic infections (such as Mycobacterium avium complex, cytomegalovirus, Pneumocystis jiroveci pneumonia, or tuberculosis), which may necessitate further evaluation and treatment.
• Be aware that severe, potentially life-threatening and fatal skin reactions have been reported, including Stevens-Johnson syndrome, hypersensitivity reaction, and toxic epidermal necrolysis. Immediately discontinue drug if severe hypersensitivity, severe rash, or rash with systemic symptoms or liver aminotransferase elevations develops. Closely monitor clinical status, including liver aminotransferases.

Patient teaching

• Tell patient drug may be taken with or without food.
• Inform patient with phenylketonuria that chewable tablets contain phenylalanine.
• Inform patient that drug doesn't cure HIV infection or reduce risk of passing it to others through sexual contact, needle sharing, or blood exposure.

Advise patient to immediately report muscle weakness, urinary problems, new infections, rash, fever, general malaise, swelling of face or throat, or chest pain.
• Instruct female patient to notify prescriber if she is pregnant or intends to become pregnant.
• Caution breastfeeding patient to discontinue breastfeeding while taking drug, because of potential HIV transmission and adverse reactions in infants.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs and tests mentioned above.

Nursing implications

Nursing assessment

  • Assess patient for change in severity of HIV symptoms and for symptoms of opportunistic infections during therapy.
  • Monitor for anxiety, depression (especially in patients with a history of psychiatric illness), suicidal ideation, and paranoia during therapy.
  • Assess for rash periodically during therapy. May cause Stevens-Johnson syndrome. Discontinue therapy if severe or if accompanied with fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, hepatitis, and/or eosinophilia.
  • Lab Test Considerations: Monitor viral load and CD4 counts regularly during therapy.
    • May casue ↓ ANC, hemoglobin, and platelet counts.
    • May cause ↑ serum glucose, AST, ALT, GGT, total bilirubin, alkaline phosphatase, pancreatic amylase, serum lipase, and creatinine kinase concentrations.

Potential Nursing Diagnoses

Risk for infection (Indications)
Noncompliance (Patient/Family Teaching)


  • Tablets are not interchangeable with chewable tablets or packets for oral suspension.
  • Oral: May be administered without regard to meals.
    • Swallow tablets whole; do not break, crush, or chew.
    • Chewable tablets may be chewed or swallowed.
    • Pour packet for oral solution into 5 mL of water and mix. Once mixed, administer with syringe orally within 30 min of mixing. Discard unused solution.

Patient/Family Teaching

  • Emphasize the importance of taking raltegravir as directed, at evenly spaced times throughout day. Do not take more than prescribed amount and do not stop taking without consulting health care professional. Take missed doses as soon as remembered unless almost time for next dose. Do not double doses. Advise patient to read Patient Information sheet before starting therapy and with each prescription renewal in case changes have been made.
  • Instruct patient that raltegravir should not be shared with others.
  • Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and consult health care professional before taking any new medications.
  • Inform patient that raltegravir does not cure AIDS or prevent associated or opportunistic infections. Raltegravir does not reduce the risk of transmission of HIV to others through sexual contact or blood contamination. Caution patient to use a condom during sexual contact and to avoid sharing needles or donating blood to prevent spreading the AIDS virus to others. Advise patient that the long-term effects of raltegravir are unknown at this time.
  • Advise patient to notify health care professional if they develop any unusual symptoms, if any known symptom persists or worsen, or if signs and symptoms of rhabdomyolysis (unexplained muscle pain, tenderness, weakness), rash, or depression or suicidal thoughts occur.
  • Immune reconstitution syndrome may trigger opportunistic infections or autoimmune disorders. Notify health care professional if symptoms occur.
  • Advise patients to notify health care professional if pregnancy is planned or suspected. Breast feeding should be avoided during therapy.
  • Emphasize the importance of regular follow-up exams and blood counts to determine progress and monitor for side effects.

Evaluation/Desired Outcomes

  • Delayed progression of AIDS and decreased opportunistic infections in patients with HIV.
  • Decrease in viral load and improvement in CD4 cell counts.

In addition, two small, nonrandomized studies showed no significant decline in cell-associated HIV DNA or unspliced RNA in the gastrointestinal tract following intensification with raltegravir (n = 7) and no change in HIV RNA in the CSF following intensification with maraviroc, lopinavir/ritonavir or enfurvitide (n = 10)
Washington, Sep 24 (ANI): A drug approved in 2007 for the treatment of AIDS- raltegravir or Isentress-could also play a role in preventing the herpes virus, found a new study.
The researchers then soaked the crystals in solutions of the integrase inhibiting drugs Raltegravir (also known as Isentress) and Elvitegravir and observed for the first time how these antiretroviral drugs bind to and inactivate integrase.
Recent intensification studies with raltegravir added to apparently effective therapy, have failed to make an impact on this background viral release, when monitoring with ultra-sensitive viral load assays.
It is important for patients at any stage of HIV to have treatment options like raltegravir that are effective and have a demonstrated tolerability profile in order to help them manage their disease.
The three new drugs in these classes are etravirine, maraviroc, and raltegravir (6).
The updated recommendations also give a boost for using recently-approved drugs, including raltegravir, maraviroc and etravirine, in combination with older treatments to keep down viral levels and boost CD4 counts.
Studies show that 75 per cent of patients receiving the drug raltegravir have a reduction in HIV viral load in their blood, compared with 40 per cent taking a dummy drug.
