If you’ve come across a small, blue, oval-shaped pill stamped with “L368,” you may be wondering what it is, what it’s used for, and — more importantly — whether it’s safe, especially for individuals dealing with addiction or chronic pain. The L368 blue pill is naproxen sodium, a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain and reduce inflammation. It’s available over the counter and prescribed under various brand names, such as Aleve.
But here’s the truth: just because a medication is available at your local pharmacy without a prescription doesn’t mean it’s harmless, especially if you’re in addiction recovery or managing multiple medications.
In this article, you will learn:
- What is naproxen’s role in pain management?
- Does naproxen interact negatively with other drugs?
- What are the potential side effects of naproxen?
What Exactly Is the L368 Blue Pill?
The L368 blue pill is a 220 mg naproxen sodium oral tablet. As an NSAID, it’s part of a class of drugs used to treat moderate pain, reduce swelling, and manage inflammation.
It’s commonly taken to treat the following conditions or symptoms:
- Muscle aches
- Menstrual cramps
- Arthritis symptoms (such as rheumatoid arthritis or polyarticular juvenile idiopathic arthritis)
- Back pain
- Gout symptoms
- Mild joint pain
- General body aches
While this medication isn’t classified as a narcotic painkiller, it is still a powerful pain reliever. That matters when you’re talking about people with a history of opioid painkiller use, or those vulnerable to misusing over-the-counter medications in a relapse pattern.
Naproxen vs. Narcotics: A Key Distinction
Unlike opioid medications such as oxycodone or hydrocodone, naproxen does not act on the central nervous system to block pain signals.[2] It works by inhibiting prostaglandins, which are substances in the body that cause inflammation and pain.
This is both good and bad.
Good, because naproxen does not carry the high addiction potential of narcotic painkillers.
Bad, because it can be dangerous when misused, especially when taken in large doses, or combined with other medications, including blood thinners, alcohol, or opioid pain medications.
For someone coming off narcotic painkillers or dealing with alcohol addiction, popping a few extra blue pills in search of fast pain relief might seem harmless, but this behavior could mask withdrawal symptoms, trigger internal bleeding, or cause severe stomach pain.
The Hidden Dangers: Not As Safe As You Think
Just because the L368 pill doesn’t produce a high doesn’t mean it’s without risks. Taking naproxen sodium tablets incorrectly can result in:
1. Stomach Issues
The most common and dangerous side effect is stomach irritation, which can escalate to stomach ulcers, internal bleeding, or severe stomach pain.
According to the FDA, NSAIDs like naproxen can increase the risk of gastrointestinal bleeding, particularly if:[1]
- You’re over age 60
- You’re also taking other pain relievers
- You have a history of stomach ulcers
- You’re consuming alcohol regularly
2. Heart Risks
Elevated blood pressure levels, chest pain, and increased risk of heart attack have also been reported when misusing the L368 pill. This is especially concerning for people taking blood pressure medications or those already managing high blood pressure.
3. Allergic Reactions
If you experience skin rashes, weight gain, yellowing skin, and even difficulty breathing, you might be allergic to naproxen. These allergies can lead to a medical emergency, so you should contact emergency medical services if you notice symptoms.
4. Kidney and Liver Issues
Long-term or high-dose use of naproxen can damage the kidneys or the liver, especially in combination with other drugs or if taken without the proper dosage instructions.
Who Should NOT Take Naproxen?
If you’re in addiction recovery or have loved ones who are, you need to be extra cautious. Naproxen can be risky for:
- Individuals with a history of alcohol addiction
- Those recovering from opioid dependence
- People taking blood pressure or blood-thinning medications
- Anyone with a history of stomach ulcers, kidney problems, or autoimmune disease
If this is you (or someone you care about), it’s essential to consult a healthcare provider or pharmacist before taking any pain medications, including “mild” options like the L368 blue pill.
Naproxen and Drug Interactions
Naproxen interacts with several common medications:
- Blood thinners like warfarin can dramatically increase your risk of internal bleeding.
- Opioid medications combined with naproxen can mask overdose symptoms or increase gastrointestinal risks.
- Alcohol and naproxen sodium are a dangerous combination. Together, they irritate the stomach lining and increase your risk of stomach bleeding.
- Other pain medications (including other NSAIDs like ibuprofen) should not be taken at the same time unless directed by a doctor.
If you are taking any of these medications, inform your doctor before taking naproxen. Mixing the L368 pill with these substances can result in a medical emergency.
What Should You Do If You’re In Pain?
Managing pain when you’re in recovery — or helping someone who is — can be one of the biggest challenges. But there are safe strategies.
1. Speak With a Doctor or Pharmacist
Before taking any medication — even if it’s available over the counter — ask your healthcare provider about safe alternatives. They’ll weigh your full medical history, including your addiction recovery status.
2. Avoid Self-Medicating
Whether it’s a headache or menstrual period pain, resist the urge to take more than the recommended dosage or mix medications. If the pain is persistent or worsening, seek medical help immediately.
3. Explore Non-Drug Options
Physical therapy, acupuncture, meditation, and certain non-drug pain management therapies can help with chronic pain or autoimmune diseases without the risks that come with oral medications.
Withdrawal Symptoms or Side Effects? Here’s What to Watch For
Some people develop symptoms when they stop taking naproxen suddenly after long-term use.
While not technically addictive in the way opioids are, naproxen can still lead to issues like:[3]
- Increased pain sensitivity
- Rebound inflammation
- Withdrawal-like headaches
- Mood swings
If you notice any of the following after starting or stopping naproxen, seek emergency medical attention:[3]
- Chest pain
- Severe stomach pain
- Vomiting blood
- Yellowing skin or eyes
- Difficulty breathing
- Low red blood count symptoms (like dizziness or extreme fatigue)

Frequently Asked Questions (FAQ)
1. Is naproxen a safer alternative to opioids for chronic pain?
Naproxen may be safer than opioids in terms of addiction potential, but it still poses risks, especially when used long-term or in high doses. For chronic pain, healthcare providers often recommend a combination of lifestyle changes, physical therapy, and non-drug treatments alongside medications like naproxen. Always discuss options with your provider before substituting one pain reliever for another.
2. Can naproxen affect mental health or mood during recovery?
While naproxen is not a psychoactive drug, physical side effects like pain flare-ups or sleep disturbances can indirectly impact mood, especially during recovery. Some people also experience irritability or headaches when discontinuing naproxen after prolonged use. These should be monitored and discussed with a doctor, especially if you’re in recovery from substance use.
3. What should I do if I accidentally take naproxen with alcohol?
If you’ve mixed naproxen and alcohol, monitor for symptoms such as nausea, abdominal pain, or dizziness. If you experience signs of stomach bleeding (like black stools or vomiting blood), seek emergency medical attention. Going forward, avoid combining naproxen with alcohol, especially during addiction treatment or recovery.
4. Can children or teens take the L368 blue pill?
The L368 blue pill (naproxen sodium 220 mg) is generally not recommended for children under 12 without a doctor’s guidance. In some cases, naproxen is prescribed for conditions like juvenile idiopathic arthritis, but dosages and forms differ. Never give naproxen to a child or teen without pediatric supervision, especially if they are taking other medications.
5. Is it okay to take naproxen for recurring pain, like during every menstrual cycle?
Using naproxen regularly for menstrual period pain is generally safe if you follow dosage guidelines and have no contraindications (like ulcers or kidney issues). However, regular use should be discussed with a doctor to rule out underlying issues and ensure it’s not causing cumulative harm, especially to the stomach or kidneys.
6. How long does naproxen stay in your system?
Because naproxen has a relatively long half-life, it can stay in your system for up to 12 hours, with full elimination taking about 2-4 days, depending on dose and kidney function. This is important when considering drug interactions, particularly with blood thinners, opioid medications, or blood pressure medications.
