Complete adverse effect profile including incidence rates and management
Important Safety Information
This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS Adult HSCT Patients: Most common adverse events (occurring in at least 10% of subjects in the PREVYMIS group and at a frequency at least 2% greater than placebo) are nausea, diarrhea, vomiting, peripheral edema, cough, headache, fatigue, and abdominal pain.
( 6.1 ) Adult Kidney Transplant Patients: Most common adverse event (occurring in at least 10% of subjects in the PREVYMIS group and at a frequency greater than valganciclovir) is diarrhea.
( 6.1 ) Pediatric Patients: Adverse events in pediatric patients are similar to adults.

6.1 Clinical Trials 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.
Adult CMV-seropositive Recipients [R+] of an Allogeneic HSCT Prophylaxis Through Week 14 (~100 days) Post-HSCT The safety of PREVYMIS was evaluated in a Phase 3 randomized, double-blind, placebo-controlled trial (P001) in which 565 subjects were randomized and treated with PREVYMIS (N=373) or placebo (N=192) through Week 14 post-HSCT.
Adverse events were those reported while subjects were on study medication or within two weeks of study medication completion/discontinuation.
The mean time for reporting adverse events and laboratory abnormalities was approximately 22% longer in the PREVYMIS arm compared to the placebo arm.
Cardiac Adverse Events The cardiac adverse event rate was higher in subjects receiving PREVYMIS (13%) compared to subjects receiving placebo (6%).
The most common cardiac adverse events were tachycardia (reported in 4% of PREVYMIS subjects and in 2% of placebo subjects) and atrial fibrillation (reported in 3% of PREVYMIS subjects and in 1% of placebo subjects).
5 WARNINGS AND PRECAUTIONS Risk of Adverse Reactions or Reduced Therapeutic Effect Due to Drug Interactions: The concomitant use of PREVYMIS with certain drugs may result in potentially significant drug interactions, some of which may lead to adverse reactions (PREVYMIS or concomitant drugs) or reduced therapeutic effect of PREVYMIS or the concomitant drug.
Consult the full prescribing information for contraindications and dosage recommendations for concomitant drugs.
( 4 , 5.1 , 7.1 , 7.2 , 7.3 ) Risks Associated with Hydroxypropyl Betadex Excipient in Intravenous Formulation: Intravenous formulation of PREVYMIS contains the excipient hydroxypropyl betadex.
PREVYMIS injection should be used only in patients unable to take oral therapy.
If possible, intravenous administration should not exceed 4 weeks.
Like all medications, Prevymis can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
