Pain relief medications, especially opioids, are often associated with a variety of side effects. One of the most common and frustrating among them is constipation. If you're using Aspadol 100 mg, you might be wondering: Can this medication cause constipation? The short answer is yes, but there’s a lot more to understand.
In this post, we’ll break down why Aspadol can lead to constipation, who is at risk, how to prevent or manage it, and when to seek medical advice.
What is Aspadol 100 mg?
Aspadol 100 mg contains Tapentadol, a powerful prescription analgesic used to treat moderate to severe pain, including neuropathic and chronic musculoskeletal pain.
Key Features:
Acts as a mu-opioid receptor agonist
Also inhibits norepinephrine reuptake
Offers dual pain relief mechanisms
Has fewer side effects than traditional opioids like morphine
Despite being a newer generation opioid, Tapentadol is not completely free of side effects, including the potential for constipation.
How Do Opioids Like Aspadol Cause Constipation?
Opioids slow down the normal function of the gastrointestinal (GI) tract. Here's how it happens:
Reduced peristalsis: Opioids bind to receptors in the GI tract and slow intestinal muscle movement.
Increased water absorption: The longer stool stays in the colon, the more water is absorbed, leading to hard, dry stools.
Lowered sensitivity to bowel cues: You might feel the need to defecate less often, causing infrequent bowel movements.
Aspadol, despite its advanced mechanism, still binds to mu-opioid receptors, which are directly responsible for these GI effects.
How Common Is Constipation with Aspadol?
Although Aspadol has a lower risk of side effects compared to older opioids, constipation remains one of its most frequently reported adverse effects.
Clinical Statistics:
Constipation occurs in up to 20-30% of patients using Tapentadol-based medications.
The severity varies based on dosage, duration of use, and individual response.
Who Is Most at Risk?
While anyone taking Aspadol can experience constipation, certain factors may increase the risk:
Older adults
People with a history of digestive issues
Low fiber diets
Dehydration
Sedentary lifestyle
Concurrent use of other constipating medications
Symptoms of Opioid-Induced Constipation (OIC)
If you're taking Aspadol, be on the lookout for these signs:
Infrequent bowel movements (less than 3 times a week)
Hard, lumpy stools
Straining during bowel movements
A feeling of incomplete evacuation
Bloating or abdominal discomfort
How to Prevent or Manage Constipation While Taking Aspadol
Fortunately, constipation can often be prevented or managed with simple lifestyle adjustments and over-the-counter remedies.
1. Hydration
Drink plenty of water throughout the day. Aim for at least 8–10 glasses to help keep stool soft and easy to pass.
2. High-Fiber Diet
Add more fruits, vegetables, whole grains, and legumes to your meals. Fiber promotes bowel movement regularity.
3. Physical Activity
Even light exercise, such as walking, can stimulate intestinal motility.
4. Scheduled Bathroom Time
Establish a routine and try to go at the same time each day, preferably after meals.
5. Over-the-Counter Laxatives
If lifestyle changes aren’t enough:
Stool softeners like docusate sodium
Osmotic laxatives such as polyethylene glycol (MiraLAX)
Stimulant laxatives like bisacodyl (use sparingly)
Always consult your doctor before starting a laxative regimen.
Prescription Options for Opioid-Induced Constipation
In severe cases, your healthcare provider may prescribe medications specifically designed to counter opioid-induced constipation (OIC):
Methylnaltrexone (Relistor)
Naloxegol (Movantik)
Naldemedine (Symproic)
These medications target opioid receptors in the gut without affecting pain relief in the brain.
Should You Stop Taking Aspadol If You Get Constipated?
Not necessarily. Constipation is common and manageable, and discontinuing pain relief might cause unnecessary suffering. The key is balanced management. Talk to your doctor about how to continue taking Aspadol while mitigating constipation.
When to See a Doctor
Seek medical attention if:
You haven’t had a bowel movement in more than 3–4 days
You experience severe abdominal pain
You have vomiting or bloody stools
Over-the-counter treatments don’t help
Can Switching to Another Medication Help?
If constipation becomes unmanageable, your healthcare provider might recommend:
A lower dose of Aspadol
Switching to a non-opioid painkiller like acetaminophen or NSAIDs (if appropriate)
Adjunct medications like Gabapentin for nerve pain
Always make medication changes under medical supervision.

Final Thoughts
Yes, Aspadol 100 mg can cause constipation, but it’s typically manageable. Like many opioid-based pain relievers, the benefit of effective pain control must be weighed against potential side effects. With the right preventive steps and medical guidance, you can continue using Aspadol while minimizing discomfort from constipation.
If you’re starting or currently taking Aspadol and worried about digestive side effects, don’t hesitate to speak with your doctor. There are many safe and effective ways to stay regular—even while managing your pain.
