When it comes to using any form of prescription medication, it is crucial for patients to ensure that they are familiar with any of the interactions or side effects that could be experienced along the way – and there are certainly no exceptions where Naltrexone side effects are concerned. The info below will help patients to identify whether they are experiencing any side effects or allergic reactions – and whether they should seek immediate medical attention as a result thereof or not.
Minor Naltrexone Side Effects
There are many minor Naltrexone side effects that can be experienced by patients. However, not all patients will experience them. Some of the more common side effects that have been classified as minor can include, but not be limited to stomach or abdominal pain and/or cramping (mild to severe), joint pains, headaches, vomiting or nausea, general muscle aches or pains, anxiety, nervousness, trouble sleeping and general restlessness. Another of the more common Naltrexone side effects is that patients can experience unusual tiredness while using the medication.
Less Common Side Effects that have been classified as Minor
When dealing with other minor Naltrexone side effects, patients can sometimes experience less common interactions such as dizziness, coughing, constipation, hoarseness, chills, a stuffy or runny nose, sore throats, sneezing and other sinus related problems. A few other lesser experienced side effects that have been noted include a pounding or faster than average heartbeat, increased levels of thirst, irritability, diarrhea, a loss of appetite and sexual problems in men.
Serious Naltrexone Side Effects
When using Naltrexone, there are some patients who experience more serious side effects than normal. These can include severe abdominal pain, skin rashes, aching, swollen or burning eyes, blurry vision, confusion, chest pains, fever, itching, frequent, uncomfortable or painful urination and weight gain. A few other serious Naltrexone side effects that have been reported include shortness of breath, buzzing or ringing in the ears (tinnitus), hallucinations, seeing or feeling things that may not really be there, mental depression, mood swings and swelling of the lower legs, feet or facial area.
Other extremely serious Naltrexone side effects that have been experienced by some patients include yellowing of the eyes or skin (jaundice), severe fatigue, pain in the top right portion of the abdominal area that lingers for more than a few days, dark urine, abnormal bruising or bleeding, loss of appetite and light-colored bowel movements. If any of these side effects are experienced by a patient, it is crucial that they seek immediate medical attention. However, it’s important for patients to remember that if any of these symptoms worsen or do not subside after a short while, they should also contact their doctor or health care provider as soon as possible.
Other Side Effects
Along with joint and muscle pain, some patients experienced various other Naltrexone side effects including painful or twitching legs and shoulders. Tremors, stiff joints, general limb pains and spasms have also been noted from time to time. However, these side effects are usually quite rare and have been reported in less than 10% of patients.
In some instances, side effects that have an effect on a patient’s cardiovascular system can include nose bleeds, edema, changes in EKG readings, an increase in blood pressure, tachycardia and palpitations. When naltrexone is used for extended periods of time, other cardiovascular related side effects that have been reported have included pulmonary embolism, deep venous thrombosis, hot flushes, ischemic stroke, angina pectoris, unstable angina and myocardial infarction.
Skin-related side effects that have been experienced by some patients include athlete’s foot, acne, pruritus, oily skin, alopecia and cold sores. In extremely rare cases, abscesses, swelling, skin tenderness and necrosis have been reported as well. As with some of the other side effects noted above, patients should ensure that they report these to their health care provider or doctor if they persist for longer than a few days or if they become worse over time.
When dealing with Naltrexone side effects, it’s important to remember that not all patients will experience the same reactions to the same medication. If swelling of the throat, hives or other allergic reactions occur; immediate medical attention should be sought.
