Laxatives: Expiry And Effectiveness

Do laxatives go bad? Well, it depends on what you mean by go bad. Unlike food, which can become contaminated with harmful bacteria and make you sick, medicines like laxatives don't usually become toxic after their expiration date. Instead, they lose potency over time, which means they may not work as effectively as they should. This is because the active ingredients in laxatives can have different half-lives, with some ingredients lasting longer than others. While it may be tempting to take expired laxatives, especially if you're dealing with constipation, it's important to consider the potential risks. Expired medication may not be as reliable or fast-acting as fresh medication, and it's always a good idea to consult a doctor or pharmacist if you have any concerns.

Laxatives can take effect within 15-30 minutes, or up to 48-72 hours

Laxatives are a group of medications used to treat constipation. They are available in many different over-the-counter brand-name and generic products. They come in different forms, with both oral (tablets, capsules, and liquids) and rectal (enemas and suppositories) options.

The time it takes for a laxative to take effect depends on the type of laxative and how it is administered. Laxatives that are administered rectally, such as enemas and suppositories, act the fastest, typically providing relief within 15 minutes to one hour. However, they often come with a greater risk of side effects, including stomach cramping, diarrhoea, and rectal irritation. They may also be more difficult or uncomfortable for some individuals to use compared to oral medication.

Oral laxatives, on the other hand, are generally more comfortable for most people to take. The fastest-working oral laxatives include saline laxatives, such as magnesium hydroxide and magnesium citrate, and stimulant laxatives, such as senna tablets. These laxatives typically work in less than 12 hours.

For those seeking a gentler option, bulk-forming laxatives, osmotic laxatives, and stool softeners are recommended. These types of laxatives usually take longer to work, typically within 12 hours to three days. While they cause fewer side effects, they can still lead to some bloating, gas, or cramping.

It is important to note that laxatives should not be the first option for relieving constipation. Lifestyle changes, such as increasing fibre intake, taking probiotics, drinking more fluids, and exercising, are usually recommended first. If these changes do not help, then it may be appropriate to consider taking a laxative.

Laxatives can cause dehydration or an electrolyte imbalance

Laxatives are intended to be used occasionally to alleviate constipation. However, they are often misused by people with eating disorders, who take them to promote weight loss. This is extremely dangerous and can lead to dehydration and electrolyte imbalances.

Laxatives deplete the body of water, which can lead to dehydration. The body compensates for this dehydration by retaining water, which can result in bloating. Dehydration caused by laxative abuse can lead to tremors, fainting, weakness, blurred vision, and even organ damage and death.

Laxatives can also cause electrolyte imbalances, as they cause the body to lose electrolytes such as sodium and potassium at abnormally high rates. Electrolytes are essential for the proper functioning of nerves and muscles, including the heart. Imbalances can lead to tremors, vomiting, urinary tract infections, kidney failure, muscle spasms, and heart attacks, which can be fatal.

The overuse of laxatives can also lead to long-term and potentially permanent damage to the digestive system, including the colon. This includes chronic constipation, impaired intestinal function, and damage to the nerves and muscles of the colon. Laxatives strip away the protective mucus that lines the colon, leaving it susceptible to infections and irritation. This increases the risk of developing irritable bowel syndrome and bowel tumors.

Laxatives can interact with other medications, such as antibiotics and heart medications

Laxatives are substances that affect your digestive system by loosening stool and stimulating bowel movements. While they can be effective for constipation relief, it's important to exercise caution when taking them, especially if you're concurrently on a course of medication.

According to Neilanjan Nandi, MD, a gastroenterologist and assistant professor of medicine, "some laxatives may bind up or interfere with medication absorption, such as some antibiotics or cardiac medications". This means that laxatives can interact with antibiotics and heart medications, potentially reducing their effectiveness.

Laxatives may bind to antibiotics, for example, preventing them from being properly absorbed into the body. This could result in the antibiotic not working as intended, leaving you vulnerable to infection or illness. Similarly, laxatives could interfere with the absorption of heart medication, which could be dangerous for individuals with heart conditions.

If you're taking antibiotics or heart medication, it's crucial to consult your physician or pharmacist before taking any laxatives. They can advise on potential drug interactions and recommend alternative treatments for constipation. It's also important to be cautious about taking laxatives if you're pregnant, as they can cause unpleasant side effects such as excessive gas, bloating, intestinal cramping, and dehydration.

Laxatives should be stored in a cool, dry, dark place

Laxatives are sensitive to heat, humidity, and light. Therefore, it is important to store them in a cool, dry, and dark place.

Firstly, laxatives should be stored in a cool place. This is because heat can cause the active ingredients in laxatives to break down and become less effective. Intense heat can accelerate the breakdown of active ingredients, reducing their potency. For example, aspirin loses potency over time, and direct sunlight can cause further degradation.

Secondly, it is important to keep laxatives in a dry place. This is because moisture can affect the effectiveness of the medication. For example, liquid forms of medication, such as cough syrup, can be affected by the evaporation of the alcohol content or the settling of the active ingredient. Additionally, moisture can provide an environment for bacterial growth, which can contaminate the medication.

Lastly, laxatives should be stored in a dark place. Light exposure can cause medications to degrade faster. Direct sunlight acts as a disinfectant, which can be detrimental to medications that rely on microorganism activity, such as fermenting pickles or alcohol. UV light can also alter the chemical composition of medications, affecting their flavour and effectiveness.

Therefore, to maintain the potency and safety of laxatives, it is crucial to store them in a cool, dry, and dark place, such as a bedroom away from windows and lamps.

Laxatives should not be flushed down the toilet or poured down the drain

The best way to dispose of unused or expired laxatives is to drop them off at a drug take-back site, location, or program. These sites are designed to properly dispose of medications in a way that does not harm the environment or put people at risk.

It is also worth noting that flushing medications down the toilet can also cause plumbing issues. Laxatives, like other medications, are designed to alter human physiology at low doses and so can make particularly potent contaminants. This means they can cause clogs in pipes and drains, which can be costly and time-consuming to fix.

Overall, it is important to dispose of laxatives and other medications properly to protect both the environment and public health.
