What is Hyoscyamine?

What is Hyoscyamine used for?

How Hyoscyamine works

Hyoscyamine is an anticholinergic. It works by blocking a chemical in your body called acetylcholine, which controls muscle movement and secretions.

By blocking acetylcholine, hyoscyamine helps relax muscles in your stomach, intestines, and bladder. This can reduce cramping, spasms, and extra secretions.

Pharmacist tips for Hyoscyamine

pharmacist
  • Take hyoscyamine exactly as prescribed. You’ll usually take it 30 minutes to 1 hour before meals.
  • Hyoscyamine can cause dizziness and raise your risk of falling. Let your prescriber know if you're taking benzodiazepines, anxiety medications, or muscle relaxants. These can make side effects like sleepiness and confusion worse.
  • If you take antacids, take hyoscyamine before meals and your antacid after meals. This helps both medications work properly.
  • Hyoscyamine can cause dry mouth because it lowers saliva. Drink enough water to stay comfortable.
  • Hyoscyamine can affect your thinking and reaction time. Don’t drive or do tasks that need focus until you know how it affects you.
  • Hyoscyamine can make you sweat less, which can raise your risk of overheating. Drink plenty of water and be careful in hot weather.
  • Hyoscyamine can make it harder to urinate. Contact your prescriber if you have difficulty urinating or pain.

How to take hyoscyamine:

  • Immediate-release and extended-release tablets: Swallow the tablets whole. Don’t crush, chew, or split them. Talk to your prescriber if you have trouble swallowing.
  • Sublingual tablet: Place the tablet under your tongue to dissolve. Don’t eat, drink, or smoke while it’s dissolving. You can swallow your saliva, but don’t swallow the tablet.
  • Dissolvable tablet (ODT): Make sure your hands are dry before handling the medication. Place the tablet on your tongue and let it dissolve.

Hyoscyamine liquid:

  • The oral drops contain 0.125 mg/mL and the elixir contains 0.125 mg/5 mL. Double check your bottle and the prescribed dose to avoid accidentally taking the wrong amount.
  • Store the medication bottle at room temperature and keep it in the original bottle to protect from light.
  • Use a proper measuring device to take the liquid. Don’t use household spoons because they aren’t accurate.

Risks and warnings for Hyoscyamine

Hyoscyamine can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Dizziness

Hyoscyamine can make you feel sleepy, dizzy, or have blurry vision. Don’t drive or do activities that need focus until you know how this medication affects you.

Heat intolerance

  • Risk factors: Hot environments

Hyoscyamine reduces sweating, which raises your risk of overheating or heat stroke. Symptoms include high body temperature, dry skin, and confusion. Stay hydrated and avoid excessive heat.

Intestinal blockage

  • Risk factors: Colostomy or ileostomy

Hyoscyamine can slow your gut too much, which can lead to serious problems like swelling or inflammation of your colon. Your risk is higher if you’ve had certain gut surgeries.

Tell your prescriber before taking hyoscyamine if you’ve ever had a colostomy or ileostomy. Sometimes diarrhea can be a sign of a blockage, and taking this medication in that case can be harmful.

Faster heart rate

  • Risk factors: Heart problems | Overactive thyroid

If you have heart problems, such as heart failure or abnormal heart rhythms, let your prescriber know. Hyoscyamine can cause your heart rate to go up, which can worsen certain heart conditions. Let your prescriber know if you notice a change with your heart rate or feel symptoms such as a pounding or racing heart.

Reduced saliva

  • Risk factors: Taking hyoscyamine for a long time

Taking anticholinergics, like hyoscyamine, for a long time can reduce how much saliva your mouth makes. This can raise your risk of cavities, gum problems, and mouth infections. It can also make your mouth feel dry and uncomfortable. Let your prescriber know if this becomes bothersome.
