This document does not contain all possible side effects and others may occur. Check with your physician for additional information about side effects.
Dosage for Reyataz
The recommended oral dosage of Reyataz depends on the treatment history of the patient and the use of other co-administered drugs.
What Drugs, Substances, or Supplements Interact with Reyataz?
Reyataz should not be taken together with ritonavir if you are also using the steroid medicine fluticasone. Reyataz may interact with digoxin, antibiotics, antifungals, antidepressants, blood thinners, calcium channel blockers, cholesterol-lowering medicines, drugs that weaken the immune system, heart rhythm medications, insulin or oral diabetes medication, medicines to treat erectile dysfunction, other HIV /AIDS medicines, or stomach acid reducers. Many other medicines can interact with Reyataz. Tell your doctor all prescription and over-the-counter medications and supplements you use.
Reyataz During Pregnancy and Breastfeeding
Reyataz should be used only when prescribed during pregnancy. It is not known if this medication passes into breast milk. Because breast milk can transmit HIV, do not breastfeed.

SLIDESHOW
A Timeline of the HIV/AIDS Pandemic See SlideshowGet emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).
Call your doctor at once if you have:
- sudden dizziness (like you might pass out);
- severe pain in your lower stomach or back;
- painful urination, blood in your urine;
- high blood sugar--increased thirst, increased urination, dry mouth, fruity breath odor, headache, blurred vision; or
- liver or gallbladder problems--nausea, vomiting, upper stomach pain, itching, fever, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
Atazanavir affects your immune system, which may cause certain side effects (even weeks or months after you've taken this medicine). Tell your doctor if you have:
- signs of a new infection--fever, night sweats, swollen glands, cold sores, cough, wheezing, diarrhea, weight loss;
- trouble speaking or swallowing, problems with balance or eye movement;
- weakness or prickly feeling, loss of bladder or bowel control; or

Common side effects may include:
- fever;
- nausea, vomiting, stomach pain, diarrhea;
- headache, muscle pain;
- depressed mood, sleep problems (insomnia);

Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adverse Reactions In Treatment-Naive Adult Subjects
The safety profile of REYATAZ in treatment-naive adults is based on 1625 subjects with HIV-1 infection in clinical trials. 536 subjects received REYATAZ 300 mg with ritonavir 100 mg and 1089 subjects received REYATAZ 400 mg or higher (without ritonavir).
The most common adverse reactions were nausea, jaundice/scleral icterus, and rash.
Selected clinical adverse reactions of moderate or severe intensity reported in ≥ 2% of treatment-naive subjects receiving combination therapy including REYATAZ 300 mg with ritonavir 100 mg and REYATAZ 400 mg (without ritonavir) are presented in Tables 7 and 8, respectively.

Adverse Reactions In Pediatric Subjects With HIV-1 Infection
REYATAZ Capsules - The safety and tolerability of REYATAZ Capsules with and without ritonavir have been established in pediatric subjects with HIV-1 infection, at least 6 years of age from the open-label, multicenter clinical trial PACTG 1020A.
The safety profile of REYATAZ in pediatric subjects with HIV-1 infection (6 to less than 18 years of age) taking the capsule formulation was generally similar to that observed in clinical studies of REYATAZ in adults. The most common Grade 2-4 adverse events (≥5%, regardless of causality) reported in pediatric subjects were cough (21%), fever (18%), jaundice/scleral icterus (15%), rash (14%), vomiting (12%), diarrhea (9%), headache (8%), peripheral edema (7%), extremity pain (6%), nasal congestion (6%), oropharyngeal pain (6%), wheezing (6%), and rhinorrhea (6%). Asymptomatic second-degree atrioventricular block was reported in <2% of subjects. The most common Grade 3-4 laboratory abnormalities occurring in pediatric subjects taking the capsule formulation were elevation of total bilirubin (≥3.2 mg/dL, 58%), neutropenia (9%), and hypoglycemia (4%). All other Grade 3-4 laboratory abnormalities occurred with a frequency of less than 3%.
Adverse Reactions In Pediatric Subjects With HIV-1 Infection: REYATAZ Oral Powder
The data described below reflect exposure to REYATAZ oral powder in 155 subjects weighing at least 5 kg to less than 35 kg, including 134 subjects exposed for 48 weeks. These data are from two pooled, open-label, multi-center clinical trials in treatment-naive and treatment-experienced pediatric subjects with HIV-1 infection (AI424-397 [PRINCE I] and AI424-451 [PRINCE II]). Age ranged from 3 months to 10 years of age. In these studies, 51% were female and 49% were male. All subjects received ritonavir and 2 nucleoside reverse transcriptase inhibitors (NRTIs).
The safety profile of REYATAZ in pediatric subjects taking REYATAZ oral powder was generally similar to that observed in clinical studies of REYATAZ in pediatric subjects taking REYATAZ capsules. The most common Grade 3-4 laboratory abnormalities occurring in pediatric subjects weighing 5 kg to less than 35 kg taking REYATAZ oral powder were increased amylase (33%), neutropenia (9%), increased SGPT/ALT (9%), elevation of total bilirubin (≥2.6 times ULN, 16%), and increased lipase (8%). All other Grade 3-4 laboratory abnormalities occurred with a frequency of less than 3%.
Adverse Reactions In Subjects With HIV-1 Infection, Co-Infected With Hepatitis B And/Or Hepatitis C Virus
In Study AI424-138, 60 subjects administered REYATAZ 300 mg with ritonavir 100 mg once daily, and 51 subjects treated with lopinavir/ritonavir 400 mg/100 mg (as fixed-dose product) twice daily, each with fixed-dose tenofovir DF/emtricitabine, were seropositive for hepatitis B and/or C at study entry. ALT levels >5 times ULN developed in 10% (6/60) of the subjects administered REYATAZ with ritonavir and 8% (4/50) of the subjects treated with lopinavir/ritonavir. AST levels >5 times ULN developed in 10% (6/60) of the subjects administered REYATAZ with ritonavir and none (0/50) of the subjects treated with lopinavir/ritonavir.
In Study AI424-045, 20 subjects administered REYATAZ 300 mg with ritonavir 100 mg once daily, and 18 subjects treated with lopinavir/ritonavir 400 mg/100 mg twice daily (as fixed-dose product), were seropositive for hepatitis B and/or C at study entry. ALT levels >5 times ULN developed in 25% (5/20) of the subjects administered REYATAZ with ritonavir and 6% (1/18) of the subjects treated with lopinavir/ritonavir-treated. AST levels >5 times ULN developed in 10% (2/20) of the subjects administered REYATAZ with ritonavir and 6% (1/18) of the subjects treated with lopinavir/ritonavir.
In Studies AI424-008 and AI424-034, 74 subjects treated with REYATAZ 400 mg once daily, 58 who received efavirenz, and 12 who received nelfinavir were seropositive for hepatitis B and/or C at study entry. ALT levels >5 times ULN developed in 15% of the subjects treated with REYATAZ, 14% of the subjects treated with efavirenz, and 17% of the subjects treated with nelfinavir. AST levels >5 times ULN developed in 9% of the subjects treated with REYATAZ, 5% of the subjects treated with efavirenz, and 17% of the subjects treated with nelfinavir. Within REYATAZ and control regimens, no difference in frequency of bilirubin elevations was noted between seropositive and seronegative subjects [see WARNINGS AND PRECAUTIONS].
Postmarketing Experience
The following events have been identified during postmarketing use of REYATAZ. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
