Muscle Cramps and Simvastatin
This is a continuation of my story with Simvastatin (part 3).
Everybody gets Charlie-horses now and then, and most of us know they are often (and not always) caused by an insufficient amount of either potassium and/or calcium and/or good-ol’ water and like most of us, I have usually been able to rub those annoying horses out of my calves without much problem throughout my life-time. But a CRAMP … oh my goodness! These cramps I have experienced since taking Simvastatin have had me screaming out in pain in the middle of the night … as if the muscle pains themselves (in my thigh) weren’t enough to cry in agony! No rubbing eased the cramps. I tried standing to help release the muscle only to learn that my leg was also so numb from the attack that I couldn’t and tended to fall instead. These muscle cramps occurred during the night only. After the first attack (and not knowing about this side-effect), I made certain to increase my supplements to possibly avoid this malaise … again to no avail. All I could do was wait them out.
Here’s some info on muscles cramps.
Muscle cramps can have many possible causes. They include:
- Poor blood circulation in the legs
- Overexertion of the calf muscles while exercising
- Insufficient stretching before exercise
- Exercising in the heat
- Muscle fatigue
- Magnesium and/or potassium deficiency
- Calcium deficiency in pregnant women
- Malfunctioning nerves, which could be caused by a problem such as a spinal cord injury or pinched nerve in the neck or back
Muscle cramps can also occur as a side effect of some drugs. Medications that can cause muscle cramps include:
- Lasix (furosemide), Microzide (hydrochlorothiazide), and other diuretics (“water pills”) used to remove fluid from the body
- Aricept (donepezil), used to treat Alzheimer’s disease
- Prostigmine (neostigmine), used for myasthenia gravis
- Procardia (nifedipine), a treatment for angina and high blood pressure
- Evista (raloxifene), an osteoporosis treatment
- Brethine (terbutaline), Proventil and Ventolin (albuterol), asthma medications
- Tasmar (tolcapone), a medication used to treat Parkinson’s disease
- Statin medications for cholesterol such as Crestor (rosuvastatin), Lescol (fluvastatin), Lipitor (atorvastatin), Mevacor (lovastatin), Pravachol (pravastatin), or Zocor (simvastatin)
Tell your doctor if you have these symptoms in case they could be related to taking Simvastatin.
