Side Effects of Tums

If you are using tums as a heartburn treatment or as a supplement, it is very important to read the dosage labels on the containers. Tums containers will tell you how much children and adults can safely consume in a 24 hour span. Consuming too many Tums can have side effects that range from mild to severe. If you are taking Tums, be on the lookout for the following:

Side Effects


Upset stomach

An upset stomach is a very common side-effect. Too many Tums can irritate your digestive tract causing pain and discomfort. The irritation in the digestive tract can also cause nausea or vomiting. These stomach pains can also cause temporary loss of appetite.

Constipation and diarrhea

An overdose of calcium carbonate can have adverse effects on the digestive system. The effects can vary from person to person. In some cases, it will cause constipation accompanied by abdominal pain, cramping and bloating. For others, excess calcium carbonate will cause intestinal irritation which leads to diarrhea. If you experience severe or chronic constipation or diarrhea, serious medical complications such as dehydration and stool impaction can occur.

Mood changes

The calcium carbonate in Tums can affect the way nerves in your brain transmit signals. If too many Tums are taken, mood swings and mental changes will occur. You may find yourself feeling confused, depressed or delirious. Seek a doctor’s advice immediately if you experience any mood swings after taking Tums.

Muscle twitching

Calcium helps you regulate muscle contraction and relaxation when you engage in physical activity. Too much calcium carbonate in your system from a Tums overdose can mean that your muscles will not know when to contract or relax. This will result in muscle twitching and spasms as your body receives conflicting signals from the brain.

Heart rate change

Heart rate irregularities are also common side effects from eating too many Tums. If you’re experiencing these irregular heart rate changes when you eat Tums, consult your doctor immediately as it could mean a life-threatening heart condition.

Others side effects

Some other side effects can include dry mouth, increased thirst or frequent urination. Dry mouth and increased thirst are signs of dehydration, so watch out for that and be sure to re-hydrate. Many people may also experience side effects such as unusual weight loss, headaches, bodily weakness, fatigue, bone and muscle pains.
