For Healthcare Professionals
Applies to delavirdine: oral tablet
The majority of adverse effects were mild to moderate in intensity during clinical trials with delavirdine alone or with other antiretroviral agents. Dermatologic effects, primarily rash, are the most common adverse effects observed and have occurred in approximately 18% of patients enrolled in Phase I and Phase II clinical trials assessing combination therapy with delavirdine. Rash has reportedly appeared in up to 44% of patients in other clinical trials. In Phase I and II trials, delavirdine treatment was discontinued in 4.3% of treated patients secondary to drug rash and severe rash occurred in 3.6% of patients.[Ref]
Rash (typically occurring on the upper body and proximal arms) presents within 1 to 3 weeks of therapy as diffuse, maculopapular, erythematous, and often pruritic. It occurs more frequently in patients with lower CD4 counts. Dose titration does not significantly reduce the incidence of rash and, furthermore, is not recommended due to the rapid development of delavirdine resistant HIV strains when subpotent dosages are administered. Most cases resolve within 2 weeks and do not require discontinuation of delavirdine. Symptomatic treatment such as diphenhydramine or topical corticosteroids has provided relief in some cases.[Ref]
Dermatologic side effects have included grade 1 rash (erythema, pruritus; 16.7%), grade 2 rash (diffuse maculopapular rash, dry desquamation; 14.3%), and grade 3 rash (vesiculation, moist desquamation, ulceration; 4.4%). During clinical trials of delavirdine with other antiretroviral agents, rashes (13.4% to 19.5%), epidermal cyst, sebaceous cyst, angioedema, dermal leukocytoclastic vasculitis, dermatitis, desquamation, diaphoresis, discolored skin, dry skin, erythema, folliculitis, fungal dermatitis, hair loss, herpes zoster or simplex, nail disorder, petechiae, non-application site pruritus, seborrhea, skin hypertrophy, skin disorder, skin nodule, urticaria, vesiculobullous rash, and wart have been reported. Erythema multiforme and Stevens-Johnson syndrome occurred rarely and typically resolved with the discontinuation of delavirdine.[Ref]
Gastrointestinal side effects have included nausea (14.7% to 20.3%), vomiting (2.5% to 6.5%), diarrhea (2.4% to 5.9%), and generalized abdominal pain (2.4% to 5%) during clinical trials of delavirdine with other antiretroviral agents. Abdominal cramps, abdominal distention, localized abdominal pain, anorexia, constipation, gastritis, gastroesophageal reflux, bloody stool, colitis, increased or decreased appetite, Clostridium difficile associated diarrhea, diverticulitis, dry mouth, dyspepsia, dysphagia, all levels of enteritis, eructation, fecal incontinence, flatulence, gagging, gastroenteritis, gastrointestinal bleeding, gastrointestinal disorder, gingivitis, gum hemorrhage, increased saliva, increased thirst, ulcers or inflammation of the mouth or tongue, oral/enteric moniliasis, rectal disorder, sialadenitis, tooth abscess, toothache, and taste perversion have also been reported.[Ref]
Other side effects have included asthenia/fatigue (5.3% to 16%), fever (1.6% to 7.1%), flu syndrome (2.4% to 7.3%), and localized pain (1.8% to 5.7%) during clinical trials of delavirdine with other antiretroviral agents. Abscess, chills, generalized or localized edema, infection, viral infection, lip edema, malaise, Mycobacterium tuberculosis infection, neck rigidity, ear pain, parosmia, otitis media, and tinnitus have also been reported.[Ref]

Hepatic failure has been reported during postmarketing experience.[Ref]
