Cardiovascular medications - cardiac glycosides
Cardiac glycosides include:
- Digoxin (Lanoxicaps, Lanoxin, Digibind)
- Digitoxin (Crystodigin)
Taking digoxin may deplete magnesium.
Magnesium deficiency affects calcium and vitamin D levels in the body. This may cause:
- Muscle cramps
- Muscle weakness
- Irregular heartbeat
- Numbness and tingling in feet and toes
- High blood pressure
Taking digitoxin may deplete potassium.
Symptoms of potassium deficiency include:
- Nausea and vomiting
- Feeling of apprehension
- Muscle pain and weakness (mostly in the legs)
- Muscle cramps
- Strong, rapid or irregular heartbeat
Vitamin B1 (Thiamine)
Taking digoxin may deplete thiamine.
Low levels of vitamin B1 may cause:
- Loss of appetite
- Short-term memory loss
Severe deficiency of vitamin B1 causes beriberi. Symptoms may include:
- Tingling or burning sensation in toes and feet
- Fluid buildup in the body (edema)
- Increased heart rate
- Heart failure
The information presented here covers some of the nutrients that may be affected when you take certain medicines. If you have any of these signs and symptoms, it does not always mean you have low levels of these nutrients.
Factors that affect the level of nutrients are:
- Your medical history
- How long you have been taking the medicine
Please talk to your health care provider. They can best address your health care needs and see if you are at risk for low levels of any nutrients.
