Also known as a Charley horse, these involuntary contractions can last for a few seconds to a few minutes in the affected muscle, and while they\u2019re common, they\u2019re also uncomfortable.

Muscle pain and weakness are among the most common side effects of these drugs, affecting <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/statin-side-effects\/\"><span style=\"font-weight: 400;\">up to 10%<\/span><\/a><span style=\"font-weight: 400;\"> of those taking them.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Statins &#8220;may affect muscle metabolism or energy production, leading to soreness or spasms,&#8221; says <\/span><a href=\"https:\/\/collaboratingdocs.com\/about-us\/\"><span style=\"font-weight: 400;\">Annie DePasquale, MD<\/span><\/a><span style=\"font-weight: 400;\">, a board-certified family medicine physician and the founder of Collaborating Docs. It is <\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC2949584\/\"><span style=\"font-weight: 400;\">not entirely understood<\/span><\/a><span style=\"font-weight: 400;\"> why statins cause muscle cramping, but it\u2019s more common in <\/span><a href=\"https:\/\/www.health.harvard.edu\/pain\/managing-statin-muscle-pain#\"><span style=\"font-weight: 400;\">women<\/span><\/a><span style=\"font-weight: 400;\"> than men.

Electrolytes are minerals with an electric charge that aid muscle contraction and nerve signals. <\/span><span style=\"font-weight: 400;\">If your prescription causes an <\/span><a href=\"https:\/\/psnet.ahrq.gov\/web-mm\/diuretics-and-electrolyte-abnormalities\"><span style=\"font-weight: 400;\">electrolyte imbalance<\/span><\/a><span style=\"font-weight: 400;\">, it can disrupt the process of muscle relaxation, leading to uncomfortable tightness.<\/span><\/p>\n<h3 id=\"bronchodilators\"><span style=\"font-weight: 400;\">Bronchodilators\u00a0<\/span><\/h3>\n<p><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK519028\/#\"><span style=\"font-weight: 400;\">Bronchodilators<\/span><\/a><span style=\"font-weight: 400;\"> are medications used to treat lung conditions such as asthma and COPD. Some of these medications, such as <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/albuterol-sulfate-hfa\/what-is\"><span style=\"font-weight: 400;\">albuterol<\/span><\/a><span style=\"font-weight: 400;\">, stimulate the nervous system. &#8220;Any medication that interferes with the nerves can cause leg cramps,&#8221; Dr. Chester notes. They can also affect potassium levels in your blood, an electrolyte that, when imbalanced, can cause leg cramps.<\/span><\/p>\n<h3 id=\"psychiatric-drugs\"><span style=\"font-weight: 400;\">Psychiatric drugs\u00a0<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A number of psychiatric treatments <\/span><span style=\"font-weight: 400;\">can cause nighttime leg cramping. &#8220;The most common medications are antipsychotic medications and depression medicines, such as <\/span><a href=\"https:\/\/www.singlecare.com\/drug-classes\/ssris\"><span style=\"font-weight: 400;\">SSRIs<\/span><\/a><span style=\"font-weight: 400;\">,&#8221; says Dr. Chester. <\/span><span style=\"font-weight: 400;\">These medications alter the levels of serotonin and dopamine in the body, which can lead to or exacerbate <\/span><a href=\"https:\/\/www.ninds.nih.gov\/health-information\/disorders\/restless-legs-syndrome\"><span style=\"font-weight: 400;\">restless legs syndrome (RLS)<\/span><\/a><span style=\"font-weight: 400;\">, a condition marked by discomfort in the legs, including aching, tingling, or burning sensations.\u00a0\u00a0<\/span><\/p>\n<h3 id=\"oral-contraceptives\"><span style=\"font-weight: 400;\">Oral contraceptives<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Certain birth control pills containing estrogen may cause hormonal changes that affect fluid retention and electrolyte balance, especially when you\u2019re starting on a new contraceptive. Similar to diuretics, when the fluid balance is disrupted, it can impair how your muscles relax, causing unwanted contractions while you sleep.<\/span><\/p>\n<h3 id=\"steroids\"><span style=\"font-weight: 400;\">Steroids<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Corticosteroids, commonly used to treat conditions ranging from arthritis to asthma, can deplete potassium levels, an essential mineral for muscle function. Similar to bronchodilators, this can mean waking up clutching your calf in the middle of the night.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\t\t<div class=\"singlecare-dynamic-newsletter-wrapper sin-newsletter-wrapper\">\n\t\t\t<span class=\"heading\">Get our wellness newsletter<\/span>\n\t\t\t<form class=\"form-wrapper\" data-newsletter-form=\"1\" data-subsource=\"Wellness Newsletter\">\n\t\t\t\t<div class=\"input-wrapper\">\n\t\t\t\t\t<label for=\"dynamic-email\">Email<\/label>\n\t\t\t\t\t<input type=\"email\" id=\"dynamic-email\" class=\"email\" required>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"input-wrapper\">\n\t\t\t\t\t<input class=\"submit-form-btn\" type=\"submit\" value=\"Click to sign up\">\n\t\t\t\t<\/div>\n\t\t\t<\/form>\n\t\t\t<p class=\"success-message\" role=\"status\" aria-live=\"polite\"><\/p>\n\t\t<\/div>\n\t<\/span><\/p>\n<h2 id=\"when-to-suspect-your-medication-is-causing-cramps\"><span style=\"font-weight: 400;\">When to suspect your medication is causing cramps<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">&#8220;If cramps begin shortly after starting a new medication or worsen with dose changes, that\u2019s a clue the drug may be involved,&#8221; Dr. DePasquale says. &#8220;Patients should also look for patterns such as cramps occurring at similar times each day or improving when a dose is skipped (though skipping doses is not recommended without medical advice).&#8221;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you notice new muscle cramping after starting a new prescription, &#8220;it\u2019s worth talking with your doctor or a pharmacist about it to determine if leg cramps are a side effect of the medication,&#8221; Dr. Chester agrees.\u00a0<\/span><\/p>\n<h2 id=\"what-to-do-if-you-suspect-medication-related-cramps\"><span style=\"font-weight: 400;\">What to do if you suspect medication-related cramps<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">You should never stop taking a prescribed medication without first consulting with your healthcare provider. However, the following strategies can help:<\/span><\/p>\n<h3 id=\"1-document-when-cramps-occur\"><span style=\"font-weight: 400;\">1. Document when cramps occur.<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Leif Hands, DC, owner of <\/span><a href=\"https:\/\/www.drlhands.com\/meet-dr-lief-hands\/\"><span style=\"font-weight: 400;\">Precise Chiropractic &amp; Rehabilitation<\/span><\/a><span style=\"font-weight: 400;\">, recommends keeping a log of when you experience muscle cramps to determine the potential cause. &#8220;I frequently advise patients to monitor their cramps in terms of how soon after taking the medication they appear and how often they occur to determine a definite link.&#8221;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Take careful notes on the timing of your nocturnal leg cramps to help determine if your medication is causing the discomfort. If the timing of the most frequent incidence of your cramping lines up with when you take your medication, that will quickly become evident within a few days of keeping track of the onset and frequency of the cramping. If you end up meeting with your healthcare provider, these notes will prove very helpful, allowing them to guide you on the road to feeling better.<\/span><\/p>\n<h3 id=\"2-review-all-medications-and-supplements\"><span style=\"font-weight: 400;\">2. Review all medications and supplements<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A healthcare professional can help you determine which of your medications, if any, could be to blame for nighttime leg cramps. Dr. DePasquale suggests asking if a dosage adjustment or alternative medication might be the solution to stopping nighttime leg cramps.\u00a0<\/span><\/p>\n<h3 id=\"3-consider-adjustments-to-your-routine\"><span style=\"font-weight: 400;\">3. Consider adjustments to your routine.<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">&#8220;<\/span><span style=\"font-weight: 400;\">Sometimes, adding an electrolyte supplement or stretching routine is all that\u2019s needed,&#8221; Dr. DePasquale says. That is why it&#8217;s important not to stop or change the dosing on your medications without first speaking to your healthcare provider. The fix may be a simple dietary or exercise adjustment that doesn&#8217;t involve stopping or changing your medications.\u00a0<\/span><\/p>\n<h2 id=\"managing-nighttime-leg-cramps\"><span style=\"font-weight: 400;\">Managing nighttime leg cramps<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Whether your nocturnal leg cramps are caused by medication or not, it&#8217;s essential to manage this painful and disruptive symptom so you can get comfortable and restful sleep. These small changes can help prevent spasms after you go to bed:<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Prioritize hydration. <\/b><span style=\"font-weight: 400;\">This includes drinking enough water and avoiding dehydrating drinks, such as alcohol and caffeine. In severe cases, an electrolyte drink such as Pedialyte may help.<\/span><\/li>\n<li aria-level=\"1\"><b>Eat a balanced diet. <\/b><span style=\"font-weight: 400;\">Particularly, \u201cmaintain balanced levels of potassium, magnesium, and calcium through a nutritious diet,&#8221; Dr. DePasquale advises. A registered dietitian can provide personalized dietary recommendations.<\/span><\/li>\n<li aria-level=\"1\"><b>Stretch before bed. <\/b><span style=\"font-weight: 400;\">&#8220;Even simple habits like ankle mobility work \u2026 have been enough at my practice to get many patients sleeping cramp-free again,&#8221; Dr. Hands says.\u00a0<\/span><\/li>\n<li aria-level=\"1\"><b>Use a heating pad. <\/b><span style=\"font-weight: 400;\">The gentle warmth can help to relax stressed muscles.<\/span><\/li>\n<li aria-level=\"1\"><b>Change your shoes. <\/b><span style=\"font-weight: 400;\">Supportive and stable footwear is important for the overall health of your leg muscles and bones.<\/span><\/li>\n<li aria-level=\"1\"><b>Get evaluated by a provider. <\/b><span style=\"font-weight: 400;\">If cramps persist, an underlying condition could be causing the problem. &#8220;If the cramps are very severe, talk to your doctor or prescriber at once,&#8221; Dr. Chester advises. &#8220;This is also a good step if you have numbness or weakness along with the cramps.&#8221;<\/span><\/li>\n<\/ul>\n<h2 id=\"the-bottom-line\"><span style=\"font-weight: 400;\">The bottom line<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Medications that affect your nervous system and electrolyte or hormonal balance can cause physical discomfort. Statins, diuretics, antidepressants, antipsychotics, some oral contraceptives, and steroids are all known to cause nighttime leg cramps. If you experience recurrent leg cramps, consult your healthcare provider about your medical history. Adjustments to your routine can help alleviate the cramps and improve your quality of life.
