Qsymia<\/span><\/a> is a prescription drug that contains two active ingredients in <\/span>one capsule<\/span><\/a>: <\/span>phentermine<\/span><\/a> and <\/span>topiramate<\/span><\/a>. It is approved for weight loss in people with obesity and people who are overweight with at least one weight-related condition, such as high blood pressure or Type 2 diabetes. It\u2019s most effective for weight management when used alongside healthy lifestyle changes, such as a reduced-calorie <\/span>diet<\/span><\/a> and exercise. If you or a loved one is taking Qsymia, it\u2019s not unusual to wonder if it\u2019s safe to have a drink with friends\u2014without sabotaging your weight-loss goals.\u00a0<\/span><\/p>\n

While mixing alcohol and Qsymia isn\u2019t generally recommended due to increased side effects and potentially reduced weight loss, many people are able to drink in moderation. Everyone is different, though, and it\u2019s best to consult a healthcare provider if you have questions about mixing the two.\u00a0<\/span><\/p>\n\t\t

Can you drink while taking Qsymia?<\/span><\/h2>\n

Most healthcare providers recommend avoiding alcohol while taking Qsymia. Both alcohol and Qsymia can slow the central nervous system (CNS), which can lead to more intense effects from both substances.\u00a0<\/span><\/p>\n

However, the FDA drug label only warns against drinking <\/span>excessive amounts of alcohol<\/span><\/a> with Qsymia. Therefore, some people may be able to drink in moderation. Drinking in moderation means consuming alcohol in limited amounts, such as one drink per day for women and up to two drinks per day for men.<\/span><\/p>\n

Keep in mind that phentermine in Qsymia is labeled as a <\/span>controlled substance<\/span><\/a> since it\u2019s similar to amphetamine and carries a risk of misuse. Adding alcohol to the mix could increase this risk.<\/span><\/p>\n

What happens if you mix Qsymia and alcohol?<\/span><\/h2>\n

Mixing Qsymia with alcohol can cause unexpected <\/span>side effects<\/span><\/a>, some of which can be serious. Side effects can range from trouble thinking clearly to more serious concerns like heart problems and an increased risk of seizures.<\/span><\/p>\n

Increased CNS side effects<\/span><\/h3>\n

Qsymia can often cause CNS side effects like dizziness and trouble with coordination. Alcohol is a CNS depressant that can cause similar side effects. Therefore, mixing the two could lead to more serious CNS side effects. While mixing both substances, it might be harder to walk straight, think clearly, and stay awake. Things like driving and operating machinery could also be dangerous due to increased drowsiness. In some cases, combining alcohol and Qsymia may increase the risk of trouble sleeping or worsen existing <\/span>sleep problems<\/span><\/a>.<\/span><\/p>\n

Worsened mental health problems<\/span><\/h3>\n

Qsymia is known to cause <\/span>mood disorders<\/span><\/a> in some people, including depression and anxiety. In fact, depression is one of the most common side effects of Qsymia. You should watch for unusual mood changes and suicidal thoughts, and seek emergency medical attention if needed. Drinking alcohol at the same time can make side effects like depression, anxiety, or mood swings worse. Alcohol can lower inhibitions, leading to <\/span>riskier choices<\/span><\/a> or deeper feelings of sadness.\u00a0<\/span><\/p>\n

Increased risk of seizures<\/span><\/h3>\n

Stopping Qsymia suddenly can increase the risk of <\/span>having seizures<\/span><\/a>. Binge drinking or quitting alcohol after consuming large amounts over time can also increase the <\/span>risk of seizures<\/span><\/a>. The risk is even higher if you have a history of epilepsy or are taking other medicines that can trigger seizures.\u00a0<\/span><\/p>\n

Potential heart problems<\/span><\/h3>\n

Phentermine in Qsymia is a stimulant, which can increase heart rate and <\/span>blood pressure<\/span><\/a>. Drinking alcohol may also cause an increase in heart rate and blood pressure and, in severe cases, may lead to an <\/span>irregular heartbeat<\/span><\/a> or chest pain. Mixing the two could worsen problems with heart rate and blood pressure, potentially leading to a heart attack, especially in people with pre-existing cardiovascular problems.<\/span><\/p>\n

Reduced weight-loss effects<\/span><\/h3>\n

Combining Qsymia and alcohol may lead to poorer weight-loss results. <\/span>Alcohol contains calories<\/span><\/a> and can lower self-control when eating. Drinking can also make it harder to stay motivated with a balanced diet and regular exercise. People might notice it\u2019s harder to lose weight or keep it off if alcohol is a regular part of their routine.<\/span><\/p>\n

\"A<\/p>\n

Are certain people at greater risk of side effects?<\/span><\/h2>\n

Some people may be more likely to experience side effects when taking Qsymia and drinking alcohol. Problems with the kidneys or liver, and older age could be risk factors for more side effects while drinking on Qsymia.\u00a0<\/span><\/p>\n

People with kidney problems<\/span><\/h3>\n

People with moderate or severe kidney problems tend to accumulate higher levels of the drug in their bodies. This extra exposure can increase the risk of side effects. Drinking alcohol could cause the kidneys to <\/span>work harder<\/span><\/a>, worsening the potential effects of taking Qsymia with kidney problems.\u00a0<\/span><\/p>\n

Healthcare providers typically recommend taking a lower dose of Qsymia for people with kidney problems and avoiding Qsymia altogether in people with serious kidney disease or who are on dialysis.<\/span><\/p>\n

People with liver problems<\/span><\/h3>\n

The liver is key to processing Qsymia in the body. If the liver isn\u2019t working well, it might be more difficult for the body to remove Qsymia, which could lead to higher drug levels and more side effects. The dose of Qsymia is reduced in people with moderate liver problems, while it should be avoided in people with severe liver disease.\u00a0<\/span><\/p>\n

Alcohol is known to cause <\/span>liver problems<\/span><\/a>, especially in large amounts over time. Therefore, people who drink heavily may have more liver problems and an increased risk of side effects from Qsymia.\u00a0<\/span><\/p>\n

Older adults<\/span><\/h3>\n

Older adults often have more medical problems and use several medicines at the same time. Their kidneys, liver, and heart may not work as well <\/span>with age<\/span><\/a>. Because of this, they could react more severely to Qsymia or alcohol. In addition, older adults who mix Qsymia and alcohol could be more likely to experience falls, which could cause severe injuries.\u00a0<\/span><\/p>\n

How long after taking Qsymia can you drink alcohol?<\/span><\/h2>\n

The active ingredients in Qsymia can stay in the body for many hours. The “half-life” is the time it takes for half of a drug to leave the body, and it often takes around five half-lives for most of a drug to be cleared from your system.\u00a0<\/span><\/p>\n

The <\/span>half-lives of each drug<\/span><\/a> in Qsymia are different:<\/span><\/p>\n
