Dicyclomine, Oral Tablet

Dicyclomine Hydrochloride Tablets are used to treat some types of cancer. They have been approved by the FDA (Food and Drug Administration) for treating certain kinds of cancers such as:

Breast Cancer

Colorectal Cancer

Lung Cancer (Cancer of Lungs)

They have not been approved for other forms of cancer.

How does it work?

It works by killing cancer cells. When a cell becomes cancerous, it produces abnormal proteins called DNA mutations. These genetic changes cause the cells to grow out of control and spread throughout your body. If they get into your blood stream or lymph system, they can affect organs like the brain and heart. It’s possible that if these genes are passed down from one generation to another, then the risk of getting cancer increases over time.

What do I need to take it?

You will need to take dicyclomine tablets at least once daily. You may want to start taking them right away after diagnosis of cancer. Some people with lung cancer may benefit from starting treatment sooner than six months. However, you should continue taking the medication even if you don’t feel well for several weeks because there is no way around side effects like nausea and vomiting when you stop taking the medicine.

What are the side effects?

Vomiting, Nausea, Stomach pain and diarrhea are the most common side effects of dicyclomine tablets. Less common side effects include:




Disturbed vision and hearing

Pain in your joints and muscles

Skin rashes and itching.

If these become too bothersome you should contact your doctor as soon as possible. Tell your doctor if you develop any serious side effects like:

Mental or mood changes

Changes in vision, speech, or balance

Severe nausea or vomiting that doesn’t go away

Pain or swelling in your legs

Problems breathing.

This is not a complete list of side effects and others may occur. Call your doctor immediately or seek medical attention if you experience any of the following symptoms

Difficulty breathing

An allergic reaction

A sharp pain in your chest that lasts for more than a few minutes

Severe sore throat that doesn’t go away or fever.

What if I forget to take the medication?

If you forget to take a dicyclomine tablet, take it as soon as you remember. If it is almost time for the next dose, then you can skip the missed dose and continue with your regular schedule. Never take a double dose of dicyclomine tablets to make up for a forgotten dose.

What precautions should I take?

If you are a woman who is pregnant or breastfeeding, or planning to get pregnant or your sexual partner is, do not take dicyclomine tablets as it may pose a health risk. If you are a woman of childbearing age, use birth control while taking this medication.

If you drink alcohol or use street drugs, tell your doctor before starting treatment with this medication.

What if I overdose?

An overdose of dicyclomine tablets is unlikely. However, if for any reason you take an overdose, you should seek immediate medical help.

You may experience some of the common side effects such as dizziness, stomach pain, or vision changes.

Things you must not do

Do not stop taking dicyclomine tablets without speaking with your doctor first. Only stop taking the medication once your doctor has advised you to. Your cancer treatment is a serious medical condition that should not be stopped suddenly. The process should be tapered off slowly as to not cause withdrawal effects.

Do not give this medication to anyone else, even if they have the same condition.

Side effects

Dicyclomine tablets may cause side effects. These side effects usually do not occur or are mild and temporary in nature, but seek immediate medical attention if you experience:


Severe dizziness or loss of balance

Severe headache or vision changes

Difficulty breathing or swallowing.

The above list is not all inclusive of possible side effects from the drug.

Things you should discuss with your physician

Be sure to discuss any and all of your medical conditions with your doctor before beginning treatment. You should always be upfront and transparent with your physician, as they can help you manage your medical condition and work with you to find the combination of medications and dosages that work best for you.
