Why is my medication causing my constipation ?

It can be frustrating when you feel the urge to get relief but can't seem to go. If you’ve reviewed your diet, lifestyle, stress levels, and you still can’t seem to find the root cause of your constipation, consider whether medication side effects are causing your symptoms. It’s important to talk to your doctor or pharmacist if you think your constipation may be related to medication. Don’t stop taking your medication without first seeking the advice of a healthcare professional.

Antidepressants

A lot of antidepressants that treat the nerve endings in the brain also affect nerve endings in the gut. That can lead to significant side effects, which can include constipation. 

Opioids

The narcotic effect of strong pain medication, such as opioids, can cause the nerves in the gut to slow down tremendously, inhibiting bowel movement which leads to constipation.  

Calcium-channel blockers

You may recognize this medication type if you suffer from high blood pressure. Their objective is to relax the muscles in blood vessels to lower blood pressure – but, one of their side effects is that they can also relax the muscles in the gut and may cause constipation

Anticholinergics (for urinary incontinence)

These medications block the effects of acetylcholine, a chemical that helps the muscles move. By blocking the action of that chemical, less movement in the muscles also includes the muscle that are in the gut – which can lead to constipation.
