Study Details

Brief summary:

This is a prospective four-armed unblinded randomized controlled trial to assess four different potential post-operative treatment options for men who undergo a vasectomy. The aims of this study are:

  • To determine whether the addition of nonsteroidal anti-inflammatory drugs (NSAIDs) to acetaminophen results in improved pain after vasectomy;
  • To determine whether the addition of opioid pain medication to acetaminophen and/or NSAIDs results in improved pain after vasectomy;
  • To determine whether the use of NSAIDs for post-operative pain management increases risk of hematoma after vasectomy.

experimental: Acetaminophen + ibuprofen

Participants are encouraged to take acetaminophen 975 mg and ibuprofen 600 mg every 6 hours for the first 48 hours to a maximum 7 days after surgery.

experimental: Acetaminophen + oxycodone

Participants are encouraged to take acetaminophen 975 mg every 6 hours for the first 48 hours to a maximum of 7 days after surgery, and a prescription for 6 tablets of oxycodone 5 mg will be prescribed to take every 6 hours as needed for pain.

experimental: Acetaminophen + ibuprofen + oxycodone

Participants are encouraged to take acetaminophen 976 mg and ibuprofen 600 mg every 6 hours for the first 48 hours to a maximum of 7 days after surgery, and a prescription for 6 tablets of oxycodone 5 mg will be prescribed to take every 6 hours as needed for pain.

Interventions

Acetaminophen

Acetaminophen is a widely used, over-the-counter medication that relieves mild to moderate pain and reduces fever. Unlike NSAIDs like ibuprofen, it does not treat inflammation or swelling.

ibuprofen

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve mild to moderate pain, reduce fever, and decrease inflammation.

oxycodone

Oxycodone is a potent semi-synthetic opioid analgesic used to treat moderate to severe pain when other treatments are insufficient

Primary outcome measure

  • Brief Pain Inventory (BPI) - Total Score [ Time Frame: 1 to 7 days post operatively ]
