Nursing implications

Nursing assessment

  • Monitor voiding pattern and assess symptoms of overactive bladder (urinary urgency, urinary incontinence, urinary frequency) to and periodically during therapy.

Potential Nursing Diagnoses

Impaired urinary elimination (Indications)


  • Do not confuse Vesicare (solifenacin) with Vesanoid (oral tretinoin).
  • Oral: Administer once daily without regard to food. Tablets must be swallowed whole; do not break, crush, or chew.

Patient/Family Teaching

  • Instruct patient to take solifenacin as directed. Advise patient to read the Patient Information before starting therapy and with each prescription refill. If a dose is missed, skip dose and take next day; do not take 2 doses in same day.
  • Do not share solifenacin with others; may be dangerous.
  • May cause dizziness and blurred vision. Caution patient to avoid driving and other activities that require alertness until response to medication is known.
  • Advise patient to notify health care professional immediately if hives; rash; swelling or lips, face, tongue, or throat; trouble breathing occurs.
  • Inform patient of potential anticholinergic side effects (constipation, urinary retention, blurred vision, heat prostration in a hot environment).
  • 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.

Evaluation/Desired Outcomes

  • Decrease in symptoms of overactive bladder (urge urinary incontinence, urgency, frequency).
