Meridia (sibutramine) is an efficient medication that can be recommended for patients suffering from obesity associated with diabetes, high blood pressure, high cholesterol and a number of other medical conditions. Never exceed the dose of Merida you have been prescribe, as an overdose of this medicine is possible. The following symptoms may indicate an overdose: headache, fast heart rate or dizziness. If you think you may have taken too much of Meridia, report this fact to your local emergency center. Never combine Meridia with depression or anxiety medications, medicines for seizures, cold or allergy medicines, narcotic pain medicines, sleeping pills, sedatives, or muscle relaxers without your doctor’s consent, as they can cause interactions and add to the drowsiness Meridia has been reported to cause in some people. This can make it impossible for you to carry on with your everyday routine. Other side effects likely to occur, especially at the beginning of your treatment can include dizziness, sore throat, cough, dry mouth, loss of appetite, upset stomach, mild skin rash, back pain, constipation, runny or stuffy nose, headache, and insomnia. More serious side effects are possible although unlikely. Make sure you tell your health care provider if you suddenly develop any of the following serious die effects associated with using Meridia: vomiting, agitation, anxiety, weakness, shortness of breath, stiff muscles, joint pain, confusion, overactive reflexes, sweating, flu symptoms, sweating, high fever, blood in your urine, easy bruising or bleeding, dangerously high blood pressure, and seizure. It can be very dangerous to take any other diet pills along with Meridia. Such medications as benzphetamine, methamphetamine, phentermine, and phendimetrazine must never be taken along with Meridia to avoid dangerous interactions. Make sure your doctor is aware of any conditions that may be contraindications for taking Meridia, such as pregnancy, breastfeeding, glaucoma, history of gallstones, depression, liver or kidney disease, any bleeding disorder, high blood pressure, heart disease, underactive thyroid, seizures, and history of heart attack or stroke. Meridia is usually taken for up to 2 years. If you need to take it for longer – talk to your doctor about it and do not continue until you get his consent.
