Avatar f tn It appears all beta blockers can cause hyperkalemia (higher than normal potassium level). Hyperkalemia secondary to beta-adrenergic receptor blockade can occur in 1% to 5% of patients and is more likely to occur in non-cardio-selective beta-blockers versus cardio-selective beta-blockers. Underlying cause can be excessive potassium intake, disturbed cellular uptake of potassium, or impaired renal excretion of potassium.
Avatar f tn High potassium in your blood (Hyperkalemia) if it's not because of your kidneys function, is associated with some medical conditions eg Lupus, Diabetes, Addison disease, hormonal disorders etc but if there isn't a medical condition causation, it can also be caused by diet and medications.... "Medications that have been linked to hyperkalemia include: -Antibiotics, including penicillin G and trimethoprim.
Avatar m tn You are correct ACE inhibitors may cause hyperkalemia (high level of potassium). It seems potassium is normally excreted by the kidneys, so disorders that decrease the function of the kidneys can result in hyperkalemia. The kidneys normally remove excess potassium from the body. Therefore, most cases of hyperkalemia are caused by disorders that reduce the kidneys' ability to excrete potassium.
Avatar m tn In a small study, phenytoin-induced seizures occurred most often in patients with serum phenytoin concentrations of 50 mcg/ml or higher.[393] Peripheral neuropathy, usually occurring weeks to months after drug initiation, has also been reported in patients receiving phenytoin. A single case report describes the onset of neuropathy within a few hours of drug administration.[9780] Adverse GI effects of phenytoin therapy include nausea/vomiting, constipation, abdominal pain, and anorexia.
Avatar m tn Sorry you wife took a turn for the worse and had to be admitted. Here is a link to some information on high potassium in the blood (hyperkalemia). http://www.webmd.com/a-to-z-guides/hyperkalemia-causes-symptoms-treatments Quote: "If you have hyperkalemia, you have too much potassium in your blood. The body needs a delicate balance of potassium to help the heart and other muscles work properly.
Avatar f tn Folic acid supplementation in folate-deficient patients with epilepsy changes the pharmacokinetics of phenytoin, usually leading to lower serum phenytoin concentrations and possible seizure breakthrough..." It however says that initiation of Folic acid and phenytoin together is beneficial. Since you can't go back and start all over again, you can take a small dose. It has been observed that as los as 1mg dose can perturb phenytoin’s levels, You may take doses lower than 1mg/day.
Avatar n tn Combining fluoxetine or paroxetine with phenytoin can also lead to increased phenytoin side effects and reduce blood levels of paroxetine. You really need to discuss the potential drug interactions with your own doctor.
1291453 tn?1272143404 You should tell your doctor if you experience any of these symptoms while taking phenytoin, so that your blood level of phenytoin can be measured and your dose reduced if necessary. " Also, he has had a major surgery, and will need time to recover. However, any changes need to be reported to the doctor.
Avatar n tn Moban® brand of molindone hydrochloride contains calcium ions which interfere with the absorption of phenytoin. Ingestion times of phenytoin and antacid preparations containing calcium should be staggered in patients with low serum phenytoin levels to prevent absorption problems”. Taken from http://www.rxlist.com/cgi/generic/phenyt_od.htm Our population is divided into 4 type of metabolizers ranging from rapid to slow metabolizers depending upon the speed of elimination of drug from body.
Avatar n tn Thank you for your question, you are relatively fine with Phenytoin and the seizure episodes in a form of lack of speech are the residue of a generalized type seizure. I don’t have a full description of your consciousness during the lack of speech episodes to decide whether this start is a partial epilepsy which can continue in a generalized or it is a generalized one from the first moment..
Avatar m tn Hello AB, welcome to the medhelp forum. Phenytoin can cause certain side effects like dizziness and mental confusion. Some people may also manifest incoordinate movements. Weight gain is not a documented side effect. It could be related to your alcohol consumption or wrong dietary habits and lack of exercise. An occasional one or two drink may be fine but moderate or large amount can cause significant increases in blood levels of phenytoin due to induction of hepatic enzymes.
744427 tn?1239379163 It is often seen in patients who are in Atrial Fibrillation as well. It can also be seen in people who have severe hyperkalemia (high serum potassium levels). If it is AVNRT type SVT, this is not a life threatening arrhythmia. Atrial Fib is also not a life threatening type of arrhythmia by itself but the risks those with it encounter is that of blood clots that can lead to stroke. So it is critical that people with Afib be treated with anticoagulant medication.
Avatar f tn During those times I had not yet been diagnosed and was able to go back to life like normal, however after the diagnosis and being on phenytoin and switching to oxcarbazepine i am feeling awful. Dizzy, nauseated, moody, extremely tired, severe headaches that come and go. All i get from my Neurologist is these are side effects that will eventually go away. Because i never know when these symptoms will come on too strong I have missed a lot of days at work during my probation period.
Avatar f tn Except for hyperkalemia, T wave abnormality alone is not diagnostic of any particular condition. There is no connection to MS. Additionally a "T" wave abnormality requires supporting evidence with other tests and relevant signs and symptoms. You shouldn't be too concerned about a EKG test as it is often false positive...it is only a tool for further dx. Hope this helps, and if you have any further questions you are welcome to respond. take care.
Avatar f tn I totally forgot to tell you that he is on Phenytoin 100mg once daily. Can this be continued and taken for a long period of time? Thank you doctor once again for your immediate reply.
Avatar n tn My 7 week old daughter, who was born five weeks premature has been having issues with hyperkalemia. Her pediatrician and the kidney specialist she had been consulting with order more labs and an ekg at our local childrens hospital. Today I got a voicemail saying that the potassium levels had went down, but all the other labs like the cretin check where abnormal and she was waiting to her from the kidney specialist. She also said that her ekg was abnormal.
Avatar f tn I have had jello feeling w/panic attack before. It is possible you are having panic attacks, but your doctor should eliminate all known medical causes for your symptoms before relegating you to a psychiatrist. I also found this for your consideraton on medicine net, a com website: "Sometimes, patients with hyperkalemia report vague symptoms including: nausea, fatigue, muscle weakness, or tingling sensations.
Avatar f tn Addition of other antiepileptic drugs like phenytoin,lamotrigene and sedatives will be helpful for controll of his night symptoms.
1936411 tn?1333831849 ve heard of that might help with the itch are trying the over the counter antihistamines or antihistamine hydroxyzine (Atarax), anticonvulsants (e.g. gabapentin, carbamazepine, phenytoin), antidepressants (e.g. amitriptyline, paroxetine, mirtazapine), and even Pregabelin (Lyrica)....
Avatar f tn A few weeks ago I woke up with yellow crust on the corner of my lips and it went away in 2 days, and today I woke up and it's in the exact same spot again except a little more then before. It doesn't hurt or itch, it feels like my lips are very very dry. I don't smoke, I have grandmal seizures and my medication is phenytoin and kepra but I didn't read anywhere that would be a side effect so I'm worried this could be a STD or something.
Avatar f tn drugs like gabapentin, phenytoin are used for hemifacial spasm. Other options are botulinum injections and microvascular decompression surgery. Hope this helps. Take care.
16467414 tn?1448304929 Too much potassium is called Hyperkalemia and it can be extremely deadly if not treated. I am trying to come off Atenolol after 7 years and a few weeks ago a doctor put me on Losartan Potassium and did not tell me that though I asked if I should avoid anything. I found out what Hyperkalemia does to you the hard way. It can kill you if levels are very high, almost did me in! Symptoms of it are muscle fatigue, weakness, paralysis, abnormal heart rhythms, and nausea.
254714 tn?1316613355 It is clinically important if ST segment is elevated or depressed as it can be a sign of ischemia (diminished blood/oxygen supply) and hyperkalemia (excessive potassium). The ST segment is important because it can show whether ischemia or infarct is present. In general, an ST segment depression (greater than 1mm) indicates ischemia while elevation (greater than 1mm) generally indicates infarction. This is applicable to an EKG with 12 leads.
Avatar m tn T-wave abnormalities requires further evidence and except for hyperkalemia (electrolyte) the T-wave alone is not a diagnostic of any medical issues. Conditions to be considered with T-waves will usually be abnormal in ventricular hypertrophy, LBBB, chronic pericarditis, and in electrolyte abnormality. Whether to see a cardiologist would depend on whether you have any supporting symptoms, health history, family history of cardiac disease, etc.
