From the Guidelines
For right lower quadrant abdominal pain in an outpatient setting, the recommended non-opioid pain management medications include ibuprofen 10 mg kg-1 every 8 hours and paracetamol 10 to 15 mg kg-1 every 6 hours (max daily dose: 60 mg/kg) 1. When managing RLQ abdominal pain, it's essential to consider the potential causes and the patient's medical history. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce inflammation and alleviate pain.
- Ibuprofen dosage suggestions are 10 mg kg-1 every 8 hours 1.
- Paracetamol (also known as acetaminophen) can be used as an alternative or in combination with ibuprofen, with a recommended dosage of 10 to 15 mg kg-1 every 6 hours (max daily dose: 60 mg/kg) 1. It's crucial to advise patients to seek immediate medical attention if pain worsens significantly, as RLQ pain can indicate serious conditions like appendicitis. Patients with kidney disease, liver disease, or gastric ulcers should use caution with NSAIDs, while paracetamol requires caution in patients with liver disease. Adequate hydration should be maintained while using these medications.
- Other NSAIDs like diclofenac and naproxen may also be considered, but ibuprofen and paracetamol are preferred due to their well-established safety and efficacy profiles 1.

Nonopioid pain management medications for right lower quadrant (RLQ) abdominal pain in an outpatient setting include:
- NSAIDs such as naproxen, ibuprofen, and ketorolac These medications can be used to treat short-term pain and inflammation. However, it is essential to use the lowest effective dose for the shortest duration possible and to carefully consider the potential benefits and risks of these medications. 2 3
From the Research
Nonopioid Pain Management Medications for RLQ Abdominal Pain
The following nonopioid pain management medications can be used for right lower quadrant (RLQ) abdominal pain in an outpatient setting:
- Acetaminophen: often provides adequate analgesia for acute pain 4
- Nonsteroidal anti-inflammatory drugs (NSAIDs): effective for acute pain and have anti-inflammatory properties 5, 4
- Ketorolac: a non-opioid agent with anti-inflammatory and analgesic properties, shown to be effective for acute musculoskeletal low back pain 5
Considerations for Nonopioid Pain Management
When using nonopioid pain management medications for RLQ abdominal pain, consider the following:
- Combination therapy using a nonopioid pain reliever may be effective and reduce the need for opioids 4
- The use of opioids, even for acute pain, has been questioned due to the risk of overdose and addiction 4, 6
- Nonopioid medications, such as acetaminophen and NSAIDs, are not without risks and should be used under close clinical supervision 4
Specific Studies on RLQ Abdominal Pain
Studies have shown that:
- Tramadol, an opioid, can provide significant pain reduction for patients with RLQ abdominal pain, but may not normalize abdominal examination findings indicative of acute appendicitis 7
- Nonopioid medications, such as ketorolac, may be preferable to opioids for acute pain management due to their adverse event profile 5
