Laxative tablets are a type of medicine used to treat constipation. They are available over-the-counter at pharmacies and supermarkets, as well as on prescription from a doctor. While laxatives are generally safe, they can cause side effects such as dehydration, diarrhoea, intestinal obstruction, and electrolyte imbalances. It is important to follow the instructions on the package or those provided by a doctor when taking laxatives.
Some laxative tablets have specific instructions on how to take them, such as not crushing or chewing the tablets. For example, Dulcolax® laxative tablets have an enteric coating that protects the tablet from the acidic environment of the stomach and ensures it is released in the small intestine. Crushing these tablets can destroy the coating, leading to an increased risk of stomach upset and nausea. Therefore, it is important to read the instructions and warnings on the package or consult a healthcare professional before taking any medication, including laxatives.

What You'll Learn
- Laxative tablets should not be crushed as they have an enteric coating
- Crushing can destroy the coating and increase the risk of nausea and stomach upset
- Crushing can also lead to incorrect dosage
- Crushing laxative tablets can be dangerous for patients with dysphagia
- Laxative tablets should be swallowed whole
Laxative tablets should not be crushed as they have an enteric coating
Enteric coatings are commonly used for medications that irritate the stomach or need to be targeted to the intestines. Crushing these types of tablets can also lead to an unpleasant taste, which may discourage patients from taking the medication. It is important to follow the instructions provided with the medication to ensure the effectiveness of the treatment and minimize the risk of adverse effects.
In some cases, crushing medications may be necessary for individuals who have difficulty swallowing pills. However, it is crucial to consult a healthcare professional before crushing any medication to ensure it is safe to do so and to receive guidance on the proper crushing technique and administration method.
Additionally, it is important to note that laxatives should only be used occasionally and for a short duration, typically up to a week. If constipation persists or worsens despite the use of laxatives, it is recommended to consult a doctor or healthcare provider.

Crushing can destroy the coating and increase the risk of nausea and stomach upset
Crushing laxative tablets can destroy the coating and increase the risk of nausea and stomach upset. Laxative tablets, such as Dulcolax, have a special "enteric coating" that protects the tablet from the acidic environment of the stomach and ensures it is released in the small intestine, where it is needed. This coating prevents the medication from being destroyed by stomach acid and stops it from irritating the stomach wall.
Crushing these tablets can destroy the coating, exposing the medication to stomach acid and increasing the risk of adverse effects. These effects may include nausea and stomach upset, as the unprotected medication interacts with the acidic environment of the stomach. Crushing can also cause a loss of dosage, as some of the powdered medication may be left behind in the crushing device or not properly ingested.
Therefore, it is important to follow the instructions provided with the medication. In the case of Dulcolax, the tablets should be swallowed whole and not crushed, chewed, or broken. Additionally, they should not be taken within one hour of consuming dairy products or antacids, as these can interfere with the enteric coating and affect the medication's release in the small intestine.

Crushing can also lead to incorrect dosage
Crushing laxative tablets can lead to incorrect dosage in several ways. Firstly, crushing tablets can result in medication loss, leading to underdosing. This is especially common when using a mortar and pestle, which can leave powder residue in the cup or bag, and when using disposable bags. Rinsing the crushing device with water can help reduce medication loss, but it is important to note that rinsing only once can still result in significant drug loss.
Secondly, the size of the particles produced when crushing a tablet can affect its bioavailability. Smaller particles may have higher bioavailability, and different crushing devices produce varying particle sizes.
Thirdly, the choice of delivery vehicle for a crushed tablet, such as water, applesauce, or pudding, can also affect drug absorption and bioavailability. For example, the viscosity of applesauce may delay the dissolution of the drug, reducing its bioavailability. Additionally, the volume of the vehicle is important, as the patient may not receive the full dose if they do not consume the entire amount.
Finally, crushing multiple tablets together can create unpredictable chemical and physical interactions, potentially altering the pharmacokinetics and pharmacodynamics of each drug and leading to adverse reactions. It is recommended to crush and administer each medication separately to avoid these issues.
Additionally, laxative tablets should be swallowed whole and not crushed to avoid destroying the coating on the tablet, which can increase the risk of stomach upset and nausea.

Crushing laxative tablets can be dangerous for patients with dysphagia
- Dysphagia, or difficulty swallowing, is a common issue among older adults, affecting 11-14% of those aged 65 or above. It is especially prevalent in long-term care settings, with 36% of residents experiencing dysphagia. This condition often leads to difficulties in swallowing medications, and patients may seek alternative methods of administration.
- Crushing tablets can alter the pharmacokinetics and pharmacodynamics of the drug, potentially affecting its efficacy and safety. Inappropriate crushing may result in decreased benefits, unintended side effects, and serious harm to the patient.
- Some laxative tablets have an enteric coating designed to protect the drug from the acidic environment of the stomach and ensure its release in the small intestine, where it is needed. Crushing these tablets can destroy the coating, leading to potential stomach upset and nausea.
- Crushing tablets may also affect the dosage of the medication. The fine powder obtained after crushing can be difficult to measure accurately, potentially leading to an overdose or underdose.
- Crushing and mixing laxative tablets with food or liquids can affect the bioavailability and absorption of the drug. The choice of vehicle (e.g., water, applesauce, pudding) can impact the drug's biochemistry and absorption rate.
- For patients with dysphagia, it is essential to consult a speech-language pathologist, who can evaluate and develop a safe plan for managing their medication. This may include recommending alternative dosage forms or routes of administration that do not require swallowing tablets or capsules.

Laxative tablets should be swallowed whole
Additionally, laxatives should not be taken within one hour of consuming dairy products or antacids. This is because milk and antacids can interfere with the effectiveness of laxatives by disrupting the acidic environment of the stomach. Taking laxatives with dairy products or antacids may also increase the risk of stomach upset and nausea.
It is important to always follow the directions on the product package or the advice of a doctor or pharmacist when taking laxatives or any other medication. The dosage and administration instructions may vary depending on the specific product and the individual's age, medical condition, and response to treatment.
Furthermore, laxatives are generally recommended for occasional use and should only be taken for up to a week at a time. If constipation persists or worsens after taking laxatives for a week, it is important to consult a doctor or healthcare professional.
In summary, laxative tablets should be swallowed whole to maintain the integrity of the coating and prevent potential side effects such as stomach upset and nausea. It is also important to follow the directions on the product package and avoid taking laxatives with dairy products or antacids to ensure their effectiveness and minimize the risk of adverse effects.
