What should I discuss with my healthcare provider before taking cholestyramine?
You should not use cholestyramine if you are allergic to it, or if you have:
- a blockage in your digestive tract (stomach or intestines).
To make sure cholestyramine is safe for you, tell your doctor if you have:
- chronic constipation;
- a thyroid disorder;
- kidney disease;
- liver disease; or
- coronary artery disease (clogged arteries).
This medicine may contain phenylalanine. Talk to your doctor before using cholestyramine if you have phenylketonuria (PKU).
Taking cholestyramine can make it harder for your body to absorb certain vitamins. Your doctor may recommend you take a vitamin supplement.
You may have an even greater need for vitamin supplements during pregnancy or while you are breast-feeding a baby. Follow your doctor’s instructions about taking vitamin supplements during treatment with cholestyramine.
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
How should I take cholestyramine?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Although cholestyramine is usually taken once or twice per day, this medicine may be taken up to 6 times per day. Carefully follow your doctor’s dosing instructions.
Mix the cholestyramine powder with at least 2 to 3 ounces of water or other non-carbonated beverage. You may also mix the powder with a brothy soup, crushed pineapple, or applesauce. Measure the powder using the scoop provided with your medication. Do not use any other scoop or measuring cup to measure your cholestyramine dose.
Cholestyramine works best if you take it with meals. However, your dosing schedule may depend on when you need to take any other medications. Cholestyramine should not be taken within 1 hour after or 4 hours before you take other medications.
Use cholestyramine regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Cholestyramine can affect the surfaces of your teeth. Sipping the cholestyramine/liquid mixture slowly or holding the liquid in your mouth for too long may result in tooth discoloration, enamel erosion, or tooth decay. Be sure to brush your teeth regularly while you are using this medicine.
Drink extra fluids to prevent constipation while you are taking cholestyramine.
While using cholestyramine, you may need frequent blood tests.
Cholestyramine is only part of a complete program of treatment that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.
Store at room temperature away from moisture and heat.
Diarrhea is best described as the too frequent and often urgent passage of loose or watery stools, but there is no perfect definition of the disorder.
There are many causes, and diarrhea may be a mild nuisance or a disabling dysfunction with life-threatening consequences. Therefore, if you have anything more than mild, short-term diarrhea, you should consult a physician to obtain a diagnosis and specific treatment. If you have blood in the stool, signs of dehydration, weight loss, or fever such a consultation is urgent.
Acute diarrhea is usually short lived. In the case of viral infection, it must run its course. Antibiotics may shorten the duration of some parasitic and bacterial infections. Sometimes diagnosis is impossible or delayed, there is persistent diarrhea during or despite specific treatment, or intermittent diarrhea is part of irritable bowel syndrome (IBS).
The symptom of diarrhea can usually be managed until the underlying disease is brought under control. Sometimes, diarrhea persists despite everyone’s best efforts.
People often underestimate the dehydrating effect of diarrhea, especially if it results from an acute infection in a hot climate. Dehydration may be less noticed in the elderly who often fail to experience appropriate thirst.
Fluid losses must be replaced. For mild episodes, drinking extra water may suffice. But where fluid losses are great, sodium and potassium may also be lost, so the glucose/saline solution recommended by the World Health Organization may be restorative. Your pharmacy will have a commercial version of this solution known as oral replacement therapy (ORT).
ORT is especially important for young children and the elderly. Severe cases may require fluids administered intravenously. For mild cases, soups and juices may suffice. For some acute diarrheal illnesses, hydration is all that is required.
Signs of Dehydration
General signs of dehydration include:
- less frequent urination
- dry skin
- dark colored urine
Signs of dehydration in children include:
- dry mouth and tongue
- no tears when crying
- no wet diapers for 3 hours or more
- sunken abdomen, eyes, or cheeks
- high fever
- listlessness or irritability
- skin that does not flatten when pinched and released
Although you may have undergone investigation that has excluded dietary causes, you should know that several commonly ingested substances tend to loosen stools.
Caffeine is present in coffee, tea and cola drinks. Reduced caffeine intake or decaffeinated drinks may ease your diarrhea. (Beware that sudden cessation of caffeine may cause headaches, so withdraw slowly.)
Sorbitol, a common artificial sweetener in certain preserves, gum, and candy, has laxative effects and should also be avoided.
Since the ability to absorb lactose (milk sugar) may be impaired, you should avoid milk products until the diarrhea improves.
While reducing food intake may be wise in acute diarrhea, it is important to maintain nutrition if the attack lasts more than a few days.
For severe diarrhea, it may be necessary to avoid solid foods for a time, maintaining nutrition with clear fluids, that is, fluids with sugars and proteins through which light passes such as juices, consommé, and jellies. Some soft drinks and sweet juices may contain sugars that are difficult to absorb and therefore may aggravate the diarrhea. After acute infections, lactose and complex carbohydrates may be ill absorbed and should be avoided for a few days.
Psyllium (Metamucil, Fybogel, generics) – One teaspoonful of psyllium twice daily is often recommended for constipation, so why use it for diarrhea? The answer is that it has a water-holding effect in the intestines that may help bulk up watery stool. Some doctors recommend it for the variable bowel habit of IBS. It also has the ability to bind some toxins that may be the cause of acute diarrhea. Obviously, psyllium products combined with laxatives should be avoided.
Before taking any medication, whether over the counter or prescription, talk to your healthcare provider or pharmacist about dosage, other medicines you are taking, or any other questions you might have about the treatment. Otherwise, carefully follow the directions on the drug package or on your prescription label.
Over the Counter (OTC) Drugs
Bismuth (Pepto-Bismol, generics) – This preparation is sometimes recommended for traveler’s diarrhea and chronic microscopic colitis. It has many disadvantages. The dose is 30ml of the pink liquid every 30 minutes up to 8 times a day. It turns the stool black and may interfere with the absorption of other drugs such as diphenoxylate (See below) and tetracycline. Chronic, excessive use may cause neurological complications and the salicylate component of the drug may cause salicylate toxicity.
Codeine – Codeine 15 mg. combined with acetaminophen (Tylenol, generic) is available by prescription or over the counter (OTC) in some jurisdictions. If nothing else is handy when stricken with acute diarrhea, two such tablets may help control your acute diarrhea until a regular antidiarrheal drug can be obtained. Beware that overuse use of an OTC codeine combination could include toxic doses of acetaminophen.
Loperamide (Imodium) – The safest of the opioid drugs, loperamide is available OTC in 1 and 2mg doses. Depending on age, the recommended dose is 2 mg after each loose bowel movement to a maximum of 16 mg/day. It has an opioid’s ability to slow gut transit and improve absorption of water from the intestines. Some evidence suggests it also improves anal sphincter tone. Although it has the lowest addiction potential of all opioids, it may cause sedation, nausea, and cramps. It is the best emergency treatment for mild attacks of diarrhea, and when taken preventively it may even help you avoid urgent exits during meetings or other events.
Codeine phosphate (generic) – The usual therapeutic dose of Codeine is 30 to 60 mg up to every four hours as necessary to control diarrhea. For this, a prescription is required in most jurisdictions. Codeine is potentially addicting, and unsuitable for chronic diarrhea. It is sedating, and causes nausea, making it a second choice after loperamide.
Diphenoxylate (Lomotil) – Because it is an opiate with some addictive potential, diphenoxylate is available only by prescription. It is combined with atropine so that excessive use will cause dry mouth and other undesirable side effects. It is useful if other drugs fail.
Cholestyramine (Questran) – Cholestyramine is a powdered resin with a plastic taste that binds bile salts and has a water-holding effect. When other treatments fail, it may relieve some cases of diarrhea. Rarely, chronic diarrhea occurs after removal of the gall bladder or the lower small intestine (ileum), and cholestyramine has a beneficial effect. Usually prescribed for patients with high cholesterol blood levels, it is available in 4mg packets and is taken with water. Occasionally, a very small dose will improve diarrhea, but for most cases, loperamide is preferable. In addition to its bad taste, cholestyramine may interfere with the absorption of some drugs and vitamins, and may cause hypersensitivity reactions. It should only be used for special cases with a doctor’s advice.
How to Use the Drugs
No medicine is risk free. Ask a pharmacist or your healthcare professional if you are not sure how much medicine to take, how often to take it, or whether an interaction may occur with any other medicine you are taking. Always tell your health care professionals about all the medicines you are taking, including OTC and prescription medicines.
For mild or acute, short-lived diarrhea, most adults may treat themselves with:
- Diet adjustments
- OTC drugs
However, if your diarrhea is severe, prolonged, or accompanied with blood, high (101°F, 39°C) fever, or 10 lb (5kg) weight loss, you should consult a doctor. Special vigilance is required at the extremes of life.
You should use drugs only as necessary, and stop them when the diarrhea stops. In the case of loperamide, you should take the drug after each loose bowel movement. If your social life or business affairs are hampered by unpredictable diarrhea, loperamide may be taken before an event to prevent embarrassing trips to the toilet. Sedation, severe abdominal cramps, or other unexplained symptoms are indications to stop the drug and seek an explanation from your doctor.
Antidiarrheal drugs should be used cautiously and with a doctor’s supervision if the diarrhea is severe. Because they delay colon evacuation, opiates may prolong an intestinal infection (colitis), and in severe colitis, they may precipitate a paralysis of the colon with dire consequences.
For anything more than mild, short-lived diarrhea, a diagnosis is necessary in order to properly treat the underlying cause.
In every case, adequate hydration must be assured. For a short time, clear fluids may suffice, and ORT is available at any pharmacy for more prolonged or severe cases.
Severe watery diarrhea, bloody stools, fever, and weight loss are warning signs requiring a doctor’s assessment and perhaps intravenous fluids and salts.
Sometimes a bulking agent such as psyllium will help, but for moderately severe acute diarrhea, food must be forgone until the diarrhea subsides, or a doctor can make recommendations.
Used as directed, loperamide after loose bowel movements is the safest OTC medication for managing diarrhea. The maximum approved daily dose for adults is 8 mg per day for OTC use and 16 mg per day for prescription use. Never take more than recommended doses. A doctor should be consulted if they fail.
Severe diarrhea can be life-threatening, so caution is important, especially in the very young and very old.

Review by Tony
I had my gallbladder removed more than a year ago and I was very happy because I was saved from the horrible pain that the gallstones caused. After the surgery, my surgeon told me that I was cured and that I was not going to miss my gallbladder. Well, to tell you the truth I now miss my gallbladder very much.
The reason for this is that after the surgery I developed nasty diarrhea, and I had a horrible time. I couldn’t think of anything else but my bowel. I couldn’t go anywhere without going to the bathroom seven or eight times and draining my bowel. I started to become isolated and afraid to get out of the house, because of the fear of this crazy diarrhea.
It was the worst time of my life and I wanted answers. I talked to a gastroenterologist and he recommended Questran Light. Man, I was saved. I am taking two packets a day, one in the morning, one at night, and I feel so much better. I know that there are people out there just like me with the same symptoms and I hope that everybody gets well because we are the ones who know how embarrassing and devastating IBS can be. So for sure I will recommend Questran, but make sure to talk to your doctor first, because not everybody can use this drug.
Do you suffer from IBS? Have you tried Questran Light? Please contact Sophie to send in your review.

How to take it
How much to take
Your doctor will decide what dose you will receive. Your dose of QUESTRAN LITE is worked out based on your condition & whether you are taking other medicines. The dose worked out for you may be different to the dose for another patient.
The recommended dose:
- Adults – maintenance or on-going therapy 12 to 16 g of colestyramine resin equivalent to 14.1 to 18.8g of QUESTRAN LITE per day.
- Children & Infants – No dosage regimen has been established for children. Your doctor will start therapy in a child with small doses and adjust the dose, depending on the child’s response to initial therapy.
Ask your doctor if you want to know more about the dose of QUESTRAN LITE you receive.
QUESTRAN LITE should not be taken in its dry form; it must always be mixed with water or other fluids before taking.
- Add the contents of the 4g sachet to 100-150ml of water or fruit juice.
- Mix immediately by stirring vigorously.
- Continue to stir until the mixture is even (the powder will not dissolve).
- Drink the entire mixture immediately, rinse the container & drink the rinse to ensure that you have taken the full dose.
Make sure you use the full amount of water and ensure that it is well mixed before you drink it.
You can mix QUESTRAN LITE with thin soups, pulpy fruits with a high water content e.g. pureed apple or crushed pineapple. If care is taken you can mix it with carbonated drinks.
When to take it
Take QUESTRAN LITE at about the same time each day. Taking your sachet(s) at the same time each day will have the best effect. It will also help you remember when to take your sachet(s).
If you are taking other medicines, you must take them one hour before taking your QUESTRAN LITE or four to six hours after taking your QUESTRAN LITE
If you forget to take it
If it is almost time for next dose, skip the dose that you missed & take your next dose when you are meant to. Otherwise, take your dose as soon as you remember it, and then go back to taking it as you would normally.
