An aspirin overdose can occur after a single large dose (this is called an acute overdose) or develop gradually after taking lower doses for a long time (this is called a chronic overdose). An acute aspirin overdose may be accidental or intentional. A toxic dose of aspirin for a human adult is considered to be 200 to 300 milligrams per kilogram of body weight (works out to be 13,600 to 20,400mg of aspirin for a person who weighs 68 kg [approximately 150 pounds]). A dose of 500 milligrams per kilogram of body weight (34,000mg for a 68kg person) is considered a potentially lethal dose of aspirin, and could result in death.

Metoprolol is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks or strokes. These problems may be less likely to occur if blood pressure is controlled.
This medicine is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart.
In addition to the use of this medicine, treatment for your high blood pressure may include weight control and changes in the types of food you eat, especially foods high in sodium (salt). Your doctor will tell you which of these are most important for you. You should first check with your doctor before changing your diet.
Many patients who have high blood pressure will not notice any signs of the problem. In fact, many patients feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.
Remember that this medicine will not cure your high blood pressure, but it does help control it. You must continue to take it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, strokes, or kidney disease.
Take the tablet or extended-release tablet with a meal or just after you eat. You may break the extended-release tablet into two pieces, but swallow the two pieces whole and do not crush or chew them.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems, since they may increase your blood pressure.
Some foods and medicines can affect how aspirin works. Tell your doctor if you are using any of the following:Dipyridamole, methotrexate, probenecid, sulfinpyrazone, ticlopidineBlood thinner (including clopidogrel, prasugrel, ticagrelor, warfarin)Blood pressure medicineMedicine to treat seizures (including phenytoin, valproic acid)NSAID pain or arthritis medicine (including celecoxib, diclofenac, ibuprofen, naproxen)Steroid medicine (including dexamethasone, hydrocortisone, methylprednisolone, prednisolone, prednisone)
Temporary and dose-correlated vertigo and nausea in workers and patients exposed to static MFs higher than 2T have been found in several studies [34,35], while the correlation between the exposure and the metallic taste has not been confirmed [35]. No significant differences among several physiological parameters (heart rate, blood pressure, blood oxygenation, core temperature, ECG, respiratory rate) have been checked during the exposure at 8T, together with complete reversible tachycardia imputable to the stress correlated with the exam [34].
The first experiment on human thermal response to RF during a MR procedure was performed in 1985 [93]: in subjects exposed to a SAR value equal to 4 W/kg, the temperature changes and other physiological parameters, such as heart rate, were monitored. No abnormal temperature increase or changes in physiological parameters were observed. Other studies on volunteers have always reported changes in body temperature of less than 0.6 C, without alterations in parameters like heart rate, blood pressure and blood flow [94,95].
Another study on volunteers [96] exposed to MR procedures with a high whole body SAR value (6 W/kg) monitored tympanic and skin temperature, heart rate, blood pressure, oxygen saturation and skin blood flow: statistically significant changes where found in some parameters such as skin blood flow, systolic blood pressure and heart rate, but all these changes were within acceptable safety levels.
Interactions between RF and biological tissues during MR procedures could be unsafe for patients [11]. Most of the reported accidents are burns due to hot spots in presence of conducting materials close to the patient such as the leads of physiological parameters (heart rate, blood pressure, oxygen saturation and temperature) monitoring equipment. This kind of risk can be more serious in case of internal biomedical implants (aneurism clips, stent, etc) especially for implants that have elongated configurations and/or are electronically activated (neurostimulation systems, cardiac pacemakers) [10,99,100].
Like atenolol, these drugs are used to treat high blood pressure and several other heart problems. If combined with atenolol, they may reduce the contractions of your heart and slow it down more. Doctors sometimes use this combination under close supervision. Examples of these drugs include:
For people with poor circulation: If you have poor circulation in your feet and hands, you may have worse symptoms when taking atenolol. Atenolol reduces blood pressure, so you might not get as much blood to your hands and feet.
If you take atenolol and are considering having a baby, or if you are pregnant, talk to your doctor right away. Atenolol is not the only medication that treats high blood pressure. Other drugs have fewer adverse effects during pregnancy and breastfeeding. Your doctor will be able to tell you if a different drug or a dose adjustment is an option for you.
When this drug is used after a heart attack, the dosage is highly individualized. It depends on the cause and the effects of the heart attack. Your doctor will monitor your blood pressure and how your heart is responding, and may adjust your dosage. This drug is often started in the hospital.
Because atenolol can lower blood pressure, your doctor may ask that you periodically check your blood pressure while taking it. Let your doctor know if you experience blood pressure readings that are either too high or too low while taking atenolol.
As people age, they are at risk for developing more side effects from medications. It's important to take exactly the amount of pain medicine your doctor prescribes. Don't chew or crush your pills if they are supposed to be swallowed whole. Talk with your doctor or pharmacist if you're having trouble swallowing your pills.
Results: Of 407 patients, 209 (51%) were male. Mean age was 2.2 years (SD +/- 1.0). There were 329 patients (81%) seen in a HCF, of which 143 (35%) were hospitalized; 77 patients (19%) were observed at home. Symptoms occurred in 73 patients (18%): sinus tachycardia (n = 50), nausea/vomiting (n = 32), hyperactivity (n = 17), seizure (n = 3), hallucinations (n = 2), and hypertension (n = 2). The mean heart rate of patients with sinus tachycardia (n = 50, 12.3%) was 137 beats/min (SD +/- 13), with a range of 112-172 beats/min. Mean dosage of those with tachycardia was 24 mg/kg. In the 2 patients with hypertension, the maximum recorded blood pressures were 145/80 mm Hg (2-year-old boy) and 137/90 mm Hg (2-year-old girl), with heart rates of 122 and 125 beats/min, respectively. Dose ingested and patient weight was known for 218 patients. Mean dosage ingested was 12.2 mg/kg, with a range of 2.6-64 mg/kg. Eighty-eight percent of patients with a known dosage ingested 2ff7e9595c
