Let's learn exactly about the medicine given for stomach aches and cramps? (Antispasmodics)
Table of Contents ▾

Do you often experience stomach pain or a feeling of cramping? Or are you simply unable to bear the pain that comes with menstruation? Sometimes, your doctor may have prescribed a type of "spasmodic medicine" for such discomforts. That is the class of medicine, that is, antispasmodics, which is what we are going to talk about today. Let's simply understand what these are, how they work, and what precautions you should take while using them.

Simply put, what are these antispasmodics?

Think of our intestines and bladder as tubes. The walls of these tubes are made up of a special type of muscle. We call these smooth muscles . Unlike the muscles in our arms and legs, these are not controlled by us, they work automatically. For example, the food we eat moves down the intestines in a rhythmic manner, as these muscles contract and relax.

In some disease states, these smooth muscles begin to contract in an involuntary, rapid, and forceful manner. To be precise, they "spasm." That's when we get severe stomach cramps and pain. Antispasmodics are medications that stop this involuntary spasm and relax the muscles. This reduces pain and discomfort.

What are these medications used for?

Doctors prescribe antispasmodics mainly for muscle spasms in the digestive system (intestinal tract) and urinary tract. Here are some of the most common uses:

  • Irritable Bowel Syndrome (IBS) is a condition that causes stomach pain, bloating, and cramping due to problems with bowel function.
  • Colon spasms.
  • Upper abdominal pain caused by digestive problems (functional dyspepsia).
  • Menstrual cramps .
  • Severe pain caused by gallstones (Biliary colic).
  • Pain caused by pancreatitis.
  • Overactive bladder , which means having to urinate frequently and having difficulty controlling it.

Additionally, these medications are used before certain medical tests. For example, before a test such as an endoscopy, doctors may give them as an injection to relax the muscles in the intestines and make the test easier.

The different ways these medications work

Antispasmodic medications don't work in the same way. They can be divided into several main categories based on how they work. This may sound a bit scientific, but let's keep it simple.

Our muscles receive a message from the nervous system telling them to "contract." These messages are sent through chemicals called neurotransmitters . Antispasmodics work by interfering with the transmission of these messages in various ways.

Drug category How it works is simple.
Antimuscarinics These are the most commonly used. What they do is block the nerve message that tells the muscles to 'contract'. It's like stopping the person carrying the message.
Calcium channel blockers A muscle needs a mineral called calcium to contract. These medications work by blocking calcium from entering muscle cells, which prevents the muscle from contracting.
Things that directly relax smooth muscles These act directly on the muscles of the intestines through other mechanisms, relaxing them. A good example is peppermint oil.

Are Antispasmodics and Antispastics the same thing?

Yes. Although these two words sound the same, they work on two parts of the body.

  • Antispasmodics: These work on the smooth muscles in our internal organs (e.g. intestines, bladder).
  • Antispastics: These work on the skeletal muscles that are connected to our bones and that we control consciously (e.g., the muscles in our arms and legs). They are given for conditions such as muscle spasms caused by nerve problems.

What are the possible side effects of this medication?

Like any medicine, these medicines can cause some side effects. However, not everyone gets them. Although most of the time these are minor, some people may experience some side effects.

It is very important to tell your doctor about any other medical conditions you have (e.g., constipation, glaucoma, heart disease) before taking this medication.

Drug category Common side effects
Antimuscarinics
(e.g. Dicyclomine, Hyoscyamine)
  • Dry mouth and eyes
  • Dizziness, drowsiness
  • Slightly blurred vision
  • Constipation or increased constipation
  • Difficulty urinating (Urinary retention)
  • Increased heart rate
Peppermint oil Side effects from these are very rare, but some people may experience heartburn or nausea.

The most important thing: Only your doctor can decide which medication is right for you, how much, and for how long. Never use a medication that a friend is taking, a pharmacy, or a prescription. Only your doctor can assess your current condition and prescribe the most appropriate treatment.

💡 Take-Home Message

  • Antispasmodics are a type of medication that relaxes the smooth muscles of the organs and is used to treat things like stomach pain, cramping, and menstrual cramps.
  • Take these medications only on the advice of a doctor. Don't forget to tell your doctor about your medical history and other medications you are taking.
  • Side effects such as dry mouth, dizziness, and constipation may occur. If you experience anything unusual, inform your doctor immediately.
  • Avoid using this category of medication from a pharmacy without a doctor's prescription.
  • If you have frequent stomach pain, changes in bowel or urinary patterns, or discomfort, it's best to talk to a doctor without being embarrassed or delaying.
