Does Pristiq cause back pain? (3+ useful tips)

In this article, we will answer the question of Pristiq causing back pain. We will also talk about the factors which can contribute to back pain while taking Pristiq, along with some useful tips to manage your back pain. 

Does Pristiq cause back pain?  

There is no evidence that Pristiq causes back pain. However, in the medication guide for Pristiq, fatigue has been mentioned as a common side effect, and fatigue is often accompanied by back pain. (1)

If you are experiencing back pain after taking Pristiq, it may be due to fatigue or muscle stiffness caused by Pristiq. The other pains associated with Pristiq are headaches and abdominal pain. There are other causes which can contribute to back pain; ensure you evaluate the cause of your back pain before treating it. (2)

If you are experiencing any unwanted side effects after taking Pristiq that are affecting your daily life activities, make sure you consult your physician for proper management. Avoid abrupt discontinuation of the medication, as it will lead to withdrawal symptoms and worsen your condition.

What does the research suggest? 

When Pristiq was administered to patients with depression, the common complaints among these individuals were nausea, vomiting, dry mouth, headache, constipation, fatigue, etc. (1)

Pristiq can also cause low sodium levels (hyponatremia) in the body. The symptoms associated with low sodium levels include fatigue, weakness, lethargy, headache, nausea, dizziness, etc. (1)

Pristiq-caused back pain has not been documented in any research studies. However, side effects such as fatigue, hyponatremia, weakness, and muscle stiffness can contribute to back pain while taking Pristiq. 

What are the factors contributing to back pain while taking Pristiq?

Back pain can be caused by many causes and is often the result of a combination of factors such as: 

  • Muscle strain: Any sudden movement or improper use of muscle can lead to muscle strain, which can cause pain. The pain feels like a stabbing sensation.
  • Poor posture: Maintaining a poor posture while sitting or standing can contribute to pain. 
  • Inactivity: Lack of activity can weaken your back muscles and contribute to pain. 
  • Age: As age increases, the bones undergo wear and tear, and with age, flexibility also decreases, which can lead to back pain. 
  • Psychological factors: Stress, anxiety, and depression can contribute to fatigue, which can increase back pain. Emotion stress is said to cause tension in the muscles, causing discomfort. 
  • Occupational factors: Work involving lifting heavy objects, repetitive movement or prolonged sitting can contribute to back pain.
  • Medical conditions: Diseases such as fibromyalgia can cause fatigue and contribute to pain. Kidney stones can radiate pain to the back.
  • Inflammatory conditions: Diseases such as ankylosing spondylitis and rheumatoid arthritis can affect the spine and joints, causing pain. 
  • Drugs: Other medications which can cause back pain include Citalopram, Atenolol, Plavis, Bonvia, Remicade, etc.  

 How to minimise back pain while taking Pristiq? 

Here are some general tips to manage back pain.

  • Maintain a good posture while sitting, standing and walking. Practice stretches that help you with your posture. You can also use a belt, which will help you keep your back straight. 
  • If you are working in a sitting position for a long time, try taking breaks and lying down from time to time. 
  • Engage in regular physical activities such as walking and swimming and practise gentle exercise. 
  • Practice stretching exercises which improve your flexibility and reduce muscle tension.
  • Manage stress by practising techniques such as meditation, deep breathing, and yoga since stress can contribute to muscle tension and back pain.  
  • You can take analgesics such as acetaminophen. Avoid ibuprofen, naproxen, cyclobenzaprine and metaxalone, as they can increase the side effects of Pristiq.
  • Maintain a healthy diet and stay hydrated. 
  • Consult your physician if you notice any unwanted changes. They will assess the cause of your problem and provide you with a proper treatment. 
  • Do not discontinue Pristiq if you experience any side effects. Abrupt discontinuation of the drug may cause withdrawal symptoms and can worsen your condition. 

In my perspective, Pristiq has not been associated with any complaints of back pain. However, Pristiq can cause fatigue and muscle stiffness, which can contribute to back pain. Back pain can be caused due to other underlying conditions or poor health management. Hence, it is essential to identify the cause before treating it.
