Let's learn more about Hyoscyamine, a medicine used for stomach aches. (Hyoscyamine Extended-Release)

Do you also often experience discomfort such as stomach ache, bloating? Or do you feel something like pain or tightness in the bladder? Hyoscyamine is a special medicine that doctors recommend for such symptoms. It may have several brand names. So, if you have been prescribed this medicine, it is very important to know exactly what it is. Let's talk about this medicine in simple terms today.

What is Hyoscyamine? What does it do to the body?

Simply put, Hyoscyamine is a drug that primarily helps relax certain muscles in your body. Specifically, it helps control pain and discomfort caused by muscle contractions in your digestive system (intestines) and bladder.

There are several main uses for this medicine:

  • Irritable Bowel Syndrome (IBS): This is the most common cause. It helps control the symptoms of IBS, such as stomach cramps, bloating, and constipation.
  • Stomach Ulcers: This is also used to relieve the pain associated with stomach ulcers.
  • Bladder Spasms: This also helps control pain and the need to urinate frequently due to involuntary contractions of the bladder muscles.

In addition, this medicine also reduces the secretion of saliva, sweat, and stomach acid in your body. In medical terms, these are called ``antispasmodic`` medicines. That is, they are medicines that control unwanted muscle contractions (spasms) in the body.

Things you need to tell your doctor before taking this medicine

Before giving you Hyoscyamine, your doctor will need to know your complete health history. Be sure to tell them if you have any of the following conditions:

Your health condition Why is it important to inform about it?
Glaucoma Because this medicine can increase eye pressure even more.
Difficulty urinating/prostate problems Medication can make this condition worse.
Heart disease or a previous heart attack Because it can affect heart rate.
Myasthenia Gravis (muscle weakness disease) Symptoms may worsen.
Stomach Obstruction or Ulcerative Colitis Because it affects the functioning of the digestive system.
If you are pregnant, trying to get pregnant, or breastfeeding It is essential to seek medical advice as it may affect the baby.
Allergies to other medications, foods, and dyes Be aware of the possibility of an allergy to hyoscyamine.

The medicine should be used in the right way.

It is very important to follow the instructions exactly when using this medicine.

  • Swallow the tablet whole with a glass of water.
  • Do not crush, chew, or break the pill. This is an ``extended-release`` (ETU) pill. This means that the medicine is released into the body over a period of hours. If you break or crush the pill, the medicine can be released into the body all at once and the side effects may increase.
  • Take the prescribed dose at the time your doctor prescribes. Never take more than the prescribed amount.
  • Although this medicine is sometimes prescribed to young children over the age of 12, special care is required. Ask your doctor about this.

Warning: This medicine is for you only. Do not give this medicine to anyone else without the advice of a doctor, even if someone else has the same symptoms as you.

What to do if you take too much medicine?

If you think you have taken too much medicine, go to the nearest hospital Emergency Department (ETU) immediately . Or call the National Poisons Information Centre at the Colombo National Hospital .

What if I miss a dose of medication?

If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at the scheduled time.

Do not take a double dose of medication for any reason.

Other medications that may interact with this medicine

Other medications you are taking may interact with Hyoscyamine. Therefore, tell your doctor about all the medications you are taking (including vitamins and herbal remedies). Especially if you are taking any of the following medications:

  • Drugs like `Amantadine`, `Benztropine`
  • Medications for depression
  • Medications for mental health conditions
  • Medicines for conditions such as allergies and hay fever
  • Antacids for gastritis (as these can reduce the absorption of Hyoscyamine, ask your doctor about keeping a gap of several hours between them)
  • Drugs such as `Donepezil`, `Galantamine`, `Rivastigmine` used for Alzheimer`s disease

This list is not complete, so it's safest to tell your doctor about everything you take.

Things to be careful about when taking medicine

  • Dizziness and blurred vision: This medicine may make you feel drowsy, dizzy, or have blurred vision. Avoid driving or operating machinery until you know how this affects you.
  • Be careful with heat: This is very important. Since this medicine reduces sweating, your body temperature can easily increase. Be very careful when exercising, especially on hot days. Avoid taking hot baths or going to the sauna. Otherwise, your body temperature can rise dangerously and you may get a heat stroke.
  • Dry mouth: Dry mouth is common . This can be managed by chewing sugar-free gum, sucking on sugar-free candy, and drinking plenty of water.
  • Effects on the eyes: Dry eyes, blurred vision, and sensitivity to light may occur. Wearing sunglasses may provide relief. If you wear contact lenses, you may experience discomfort.
  • Seeing parts of the pill when you go to the toilet: Sometimes you may see parts of the pill coming out with your stool. Don't worry about this. This means that the medicine has been released from the pill into your body, and only the remaining part, like the cover, is coming out.

What side effects might I experience?
