Nausea and vomiting, muscle weakness, and excessive drowsiness are some of the possible symptoms that may occur with an overdose of calcium. Symptoms of an overdose may occur if your dosage exceeds the Tolerable Upper Intake Level" (UL), which is 2500 mg (2.5 grams) daily. If you happen to take too much calcium, be sure to seek medical attention right away.
Calcium is an important mineral. While a deficiency in calcium is certainly more common, it is also possible to take too much calcium. A calcium overdose can cause significant side effects.
If you happen to overdose on this mineral, seek medical attention immediately.
A few of the possible calcium overdose symptoms include (but are not limited to):
- Kidney stones
- Excessive drowsiness
- Muscle weakness
- Nausea and vomiting
- Frequent urination
- Changes in your heart rate
- Constipation or diarrhea
For nutrients that can cause toxicity, a "Tolerable Upper Intake Level" (UL) is given. This is the maximum that can be taken (from all sources, including the diet) without causing significant toxicity. The UL of calcium for infants up to 12 months old has not been established. For everyone else, the UL is 2500 mg (2.5 grams) daily.
If the calcium overdose was recent, your healthcare provider may decide to "pump the stomach." Treatment for a calcium overdose (if necessary) will also involve supportive care, which consists of treating the symptoms that occur as a result of the overdose. Of course, treatment will also involve stopping the calcium (and then resuming it at a more appropriate dose, if necessary).
It is important that you seek medical attention immediately if you believe that you may have overdosed on calcium.
