Tylenol＃3（泰诺与可待因）留在系统中多久了？

Tylenol #3, also known as Tylenol with codeine, is a prescription version of the same Tylenol that's available over the counter at the drugstore. You've probably reached for Tylenol (or its generic version, acetaminophen) more than once to treat a headache, ease muscle soreness after a tough workout, or bring down a fever.

添加疑要, a prescription analgesic (pain reliever) that works on the central nervous system, is the reason Tylenol #3 is available only by prescription. Codeine is an阿片(aka narcotic), and as such can be habit-forming if not taken exactly as directed by a doctor.

Because of its high potential for误用和身体依赖性, codeine is classified as a Schedule II, III, IV, and V drug, depending on its formulation and use. Drugs containing less than 90 milligrams of codeine per dosage unit, which includes Tylenol #3, are classified as Schedule III drugs.

乙酰氨基酚和可待因都有风险与其他药物和过量的严重相互作用。如果您了解更多关于Tylenol＃3留在身体的长度，您可以更好地了解如何避免这些反应。

How Long Does It Take to Feel Effects?

After ingestion, it usually takes about an hour to begin feeling the pain-relieving effects of Tylenol #3, which can last roughly three to four hours, depending on your dosage.

Codeine is metabolized by the body intomorphine. At higher doses, morphine and otheropioidscan cause feelings of elation, analgesia, and euphoria as well as dangerous side effects, including stopping of the heart and brain damage.

可待因的常见副作用包括：

• Constipation
• Difficulty urinating
• Drowsiness
• Headache
• Lightheadedness
• 情绪变化
• 肚子痛

Common side effects of acetaminophen include:

• Headache
• Nausea

In rare cases, acetaminophen can cause a severe skin reaction that can be fatal. Call your doctor immediately if you experience any of the following side effects:

• 一种蔓延和导致起泡和剥皮的皮疹
• 粘土色粪便
• Confusion
• Dark urine
• Itching
• Jaundice
• 光线（就像你要昏倒）
• 食欲不振
• Nausea
• Noising breathing
• Severe dizziness
• Shallow breathing
• Skin redness
• Upper stomach pain
• Yellowing of the skin or eyes

泰诺＃3持续多久了？

Thehalf-life药物是药物减少到其原始浓度的一半的时间，或者另一种方式，从体内消除一半剂量需要的时间。Tylenol＃3的组分的半衰期略有不同：

• 对乙酰氨基酚：每个泰诺＃3片剂含有300毫克的乙酰氨基酚。对于大多数人来说，这种塔丁醇的血液中的半衰期为1.25至3小时。所有的药物将在24小时内通过尿液。请注意，这可能需要更长时间的肝功能。
• Codeine:There is 30 milligrams of codeine in a single Tylenol #3 tablet. Codeine takes longer to clear from the system than acetaminophen. Typically, codeine has a half-life of 2.5 to three hours and it can continue to work in the body for four to six hours. Codeine continues to show up in urine for as many as three days after being taken.

尿

尿screenings, which are the most commonly used drug tests because they are relatively easy and cost-effective to administer, can detect the codeine in Tylenol #3 in your system for up to three days after use.

Blood

血液测试较少使用，因为它们更加侵入性且昂贵而不是尿液测试，具有24小时窗口，用于检测Tylenol＃3中的可待因。

Saliva

Codeine in Tylenol #3 is detectable in oral fluid taken in saliva testing for up to four days after ingestion.

Hair

Codeine use can be detected by a hair follicle test for a longer period—up to three months.

False Positive Testing

If you consume just one poppy seed muffin or two poppy seed bagels, it can trigger a false-positive test result for opiates.Poppy seeds包含跟踪量的码。

Certain medications, including certain allergy and cold medications (diphenhydramine), sleep aids (doxylamine), and medications to treat hypertension (Verapamil), have been found to cause false-positives for opiates on enzyme immunoassay (EIA) drug tests as well.

It's important to let the lab clinician know if you have eaten anything or taken any medications or supplements that might affect your results.

Factors That Affect Detection Time

How long Tylenol #3 is detectable in your body depends on a variety of factors, including the dosage and how often you use the medication as well as your weight, age, metabolism, and overall health.

年龄

老年人往往比年轻成年人更慢的速度清除药物。

代谢

您的代谢率可能受年龄，活动水平和整体健康影响，影响Tylenol＃3的检测时间。一般来说，您的新陈代谢越慢，药物将在您的系统中仍将延长。

Overall Health

因为肝脏和肾脏在药物的代谢中发挥作用，肝脏和肾功能受损可能意味着代谢泰诺＃3需要更长时间。

频率和剂量

较高剂量的泰诺＃3需要更长时间的过程和排泄而不是较低剂量。同样，如果您一直在服用该药物，可以清除系统需要更长时间。

How to Get Tylenol #3 Out of Your System

Like other drugs, the best way to get Tylenol #3 out of your system is to stop using the drug and give your body time to process and eliminate it. Staying well-hydrated and getting regular exercise can't hurt but this doesn't mean that sweating out or flushing out the drug with tons of water will help. This method will only dilute the drug test and you'll likely have to retake it.

过量的症状

Codeine also can be extremely dangerous if there's too much of the drug in the body at once, whether it's taken alone or as an active ingredient in Tylenol #3. The same may be true of acetaminophen even though it's a non-narcotic pain reliever, but for different reasons.

If you take the medication exactly as your doctor prescribed and you're careful to not take another drug that could interact with acetaminophen or codeine, you shouldn't have any problems taking Tylenol #3.

Still, it's good to be aware of the following symptoms of a potential overdose:

• Bluish lips or skin under fingernails
• Cold, clammy skin
• 昏迷
• 痉挛
• Drowsiness
• Heavy sweating
• Low blood pressure
• Pinpoint pupils
• 呼吸骤停
• Slow, shallow, labored breathing
• 昏迷（缺乏警觉性）

Symptoms of Tylenol #3 overdose may not be evident right away, but may include:

• 腹痛
• Nausea
• Vomiting

Dangerous Interactions

对乙酰氨基酚的安全范围狭窄。如果您每天服用超过4,000毫克，则风险不可逆转肝损害that ultimately can lead to death.

For this reason, combination medications like Tylenol #3 are limited to no more than 325 milligrams of acetaminophen per tablet, capsule, or other dosage unit. Before you take another medication, read the ingredient list carefully. If the medication contains acetaminophen (or paracetamol as it's known in Europe and the UK), note how many milligrams there are per dose.

Do the math to make sure you don't exceed 4,000 milligrams in a 24-hour period. Safer yet, talk to your doctor or pharmacist before taking Tylenol #3 and another product containing acetaminophen.

Codeine may also cause serious breathing problems in some individuals, especially during the first day or two of taking it. In fact, it's generally recommended that people who have conditions such as asthma or chronic obstructive pulmonary disease (COPD) use codeine with significant caution.

Codeine can interact with other medications and substances, too. Because it affects the central nervous system, you should be careful not to take other drugs that can slow breathing or cause drowsiness while taking Tylenol #3, or before it's likely to have cleared from your system.

Do not drinkalcoholwhile using Tylenol #3. Also, you shouldn't take other medications that contain acetaminophen or that might have sedative properties, including:

• 冷或过敏药物
• Pain relievers
• Sleeping pills
• 镇静剂

Getting Help

在身体中有太多的疑声构成了几个风险。对于一个，药物可以是习惯形成的，这意味着它可能导致一个人发展依赖。

如果你一直服用泰诺＃3几周或更长时间并且想停下来，跟你的医生谈谈。它们可以通过缓慢降低您的剂量，帮助您安全地逐渐消除药物。

Withdrawal

Suddenly stopping the medication may lead to withdrawal symptoms, including:

• 烦躁不安
• 加宽的学生（眼睛中心的黑色圆圈）
• 撕裂的眼睛
• Irritability
• Anxiety
• 流鼻涕
• 难以入睡
• 睡着了
• Yawning
• 出汗
• Fast breathing
• Fast heartbeat
• Chills
• Nausea
• 食欲不振
• Vomiting
• Diarrhea
• Stomach cramps
• Muscle aches

A Word From Verywell

Even when taken as prescribed, codeine in Tylenol #3 has a high risk of dependence. If you think you are becoming dependent on the drug, talk to your doctor about treatment options, which may include medications to relieve withdrawal symptoms. Your doctor can also refer you to a mental health professional or addiction treatment facility for longer-term treatment and support.
