Adults and children 12 years of age and older: 1 to 2 tablets every 4-6 hours; no more than 8 pills in 24 hours, unless otherwise prescribed by a doctor. If you are taking more than one type of dizziness drug or have trouble sleeping after taking them, then adjust your dose as needed. Children under 12 years of age: 0.5 mg/kg body weight maximum daily dosage. If you are weighing more than 150 pounds, then you should be allowed only 100 mg per day. If you are below 150 pounds, then you can safely take 200 mg per day. Do not give anyone else any of your medications without first talking to them about it. Different people may be more likely to get certain side effects when taking certain doses of drugs simultaneously. There are many different types of interactions possible between dizziness drugs that cannot be predicted from just reading the labels alone. An example is the interaction between cyclize and warfarin (Coumadin), where combining them can cause the blood to become thinner than normal. This increases your risk of bleeding seriously enough to need medical attention. It is important to keep taking your medications as directed by your doctor. Missing doses may lead to not being able to prevent the symptoms of your condition completely. This could also put you at risk for serious complications.
