What is Dicyclomine?

Simply put, dicyclomine is a medicine that relaxes the muscles in your stomach and gut. By relaxing these muscles, it stops uncomfortable spasms and reduces sharp pain. Medical experts call this type of medicine an antispasmodic.

When your gut muscles squeeze too tightly and too fast, you feel painful cramps. This medicine stops that sudden squeezing action and calms your belly down. It is often prescribed as a liquid solution so it is easy to measure and swallow.

Things to Tell Your Doctor Before Starting This Medicine

Your safety is always the top priority. Before you take this medicine for the first time, your doctor needs to know your complete medical history. Please make sure to speak up if any of the following health conditions apply to you.

Your Health Condition Why Your Doctor Needs to Know
Glaucoma (eye pressure issue) This medicine can cause your eye pressure to increase further.
Trouble urinating or prostate problems The medicine might make it even harder for you to pass urine.
Heart disease or past heart attack Certain heart conditions do not mix well with this treatment.
Myasthenia gravis (nerve disorder) Your muscle weakness symptoms could get much worse.
Stomach infections, blockages, or severe colitis It can make existing bowel blockages or inflammation worse.
Pregnancy, trying to conceive, or breastfeeding Special care is needed to keep the baby completely safe.
Allergies to dicyclomine or other drugs Knowing this prevents unexpected and dangerous allergic reactions.

How to Use This Medicine Correctly

To get the best results from any treatment, you must follow the instructions carefully. Taking your medicine the right way keeps you safe and helps you heal faster.

  • The correct dose: Because this is a liquid medicine, shake the bottle very well before each use. Always use the special measuring cup or oral syringe that comes in the box. Never use regular kitchen teaspoons or tablespoons because they do not measure the right amount.
  • When to take it: For the best results, take this medicine about 30 minutes to an hour before a meal on an empty stomach.
  • Stick to the schedule: Take your doses at the exact times your doctor recommended, keeping an even space between them. Never change your dose or take extra medicine just because you feel like it.
  • Age guidelines: If you are over 65 years old, your body may be more sensitive to this medicine. Doctors often give older adults a lower starting dose. In rare special cases, doctors might prescribe it for infants over 6 months old, but only under strict medical supervision.

What to Do in Case of an Overdose

Imagine you accidentally took more medicine than your doctor prescribed. If this happens, do not wait or guess what to do. Go right away to the nearest hospital emergency department (ER) or A&E. If you are in the US or Canada, call 911 right away. If you are in the UK, call 999 right away.

What to Do If You Miss a Dose

If you forget to take your medicine on time, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose completely. Just continue with your normal schedule.

Never take two doses at the exact same time to make up for a missed one. Doubling up on doses can cause unwanted and dangerous side effects.

Other Medicines That May Interact With Dicyclomine

Tell your doctor about every single product you use. This includes prescription drugs, over-the-counter pills, vitamins, herbal supplements, and traditional remedies. Some substances interact with dicyclomine, changing how it works or raising your risk of side effects.

Pay special attention to these common drug categories:

  • Antacids used for heartburn or indigestion (try to take these 1 to 2 hours before or after dicyclomine).
  • Cold, flu, and allergy medicines that cause drowsiness.
  • Medicines for mental health, anxiety, or sleep problems.
  • Certain strong pain relievers and narcotics.
  • Medicines used to treat diarrhea.
  • Heart medicines such as digoxin.

This list is not complete. Always share your complete list of medicines with your doctor to stay safe.

Things to Watch Out For While Taking This Medicine

While your body adjusts to this treatment, you should keep a few important lifestyle precautions in mind to protect your health.

  • Drowsiness and blurry vision: This medicine can make you feel sleepy, dizzy, or give you blurry vision. Do not drive cars, ride bikes, or operate heavy machinery until you know how the medicine affects you.
  • Alcohol use: Drinking alcohol while taking this medicine makes drowsiness much worse. Avoid alcohol completely during your treatment period.
  • Hot weather and heat stroke: This medicine can reduce how much you sweat. Be very careful around extreme heat, hot baths, or saunas. If your body cannot cool down properly, your temperature can rise dangerously and cause a heat stroke.
  • Dry mouth: Dry mouth is a very common side effect. You can manage this by chewing sugar-free gum, sucking on sugar-free hard candies, and sipping water throughout the day. If dry mouth becomes severe, talk to your doctor.

Side Effects You Might Experience

Like all medicines, dicyclomine can cause side effects, though not everyone gets them. It helps to know which symptoms require quick medical attention and which ones are minor.

Side Effect Type What to Look For What You Should Do
Serious Allergic Reactions Skin rash, hives, itching, or swelling of your face, lips, tongue, or throat. Seek emergency medical care right away (Call 911 or 999).
Anticholinergic Toxicity Flushed face, blurry vision, extreme dryness, confusion, rapid heartbeat, trouble urinating. Contact your doctor or visit the emergency room right away.
Bowel Blockage Signs Severe stomach cramps, inability to pass stool or gas, loss of appetite, vomiting. Stop the medicine and call your doctor right away.
Mild Common Effects Mild dizziness, sleepiness, dry mouth, or mild constipation. Monitor symptoms and discuss them at your next regular visit if they persist.

How to Store Your Medicine Properly

Keep your medicine bottle safely out of the reach of young children and pets. Store it at normal room temperature, away from direct sunlight and excess moisture. Do not keep medicine in hot, steamy bathrooms. Once your prescription expires, safely throw away any leftover liquid according to local pharmacy guidelines.
