The most common side effects of dextromethorphan are listed below. Tell your healthcare provider if you have any of these side effects that bother you. Its therapeutic purpose — cough suppression — works by reducing the cough reflex in the brain. This is a big advantage to other cough suppressants that work by reducing muscle movement in the lungs.
Kratom Side Effects
People at this level often have a “robotic walk” — stumbling around in a very mechanical motion. Others lose control of their body completely and slump down in their chair or onto the floor. “Extended release” means the drug is released into your body slowly over a long period of time.

You should also be aware of what types of medications may not mix well with others. DXM can also make you sleepy if you’re using it alongside other flu or cold medications that contain active ingredients that cause drowsiness. An example of this could be chlorpheniramine, which is an antihistamine. Another common example would be doxylamine, which is found in NyQuil. The length of time that the effects of DXM last is going to depend on the dose you’re taking, whether you’re using it alongside other cold medications, and your specific metabolism and weight.
If you use it correctly and exactly as the instructions say, your risk of developing any sort of addiction to DXM would be low. In some cases, DXM can also be misused for recreational purposes. DXM is the dextrorotary enantiomer of racemethorphan (3-methoxy-17-methylmorphinan), an opioid. DXM is a N-methyl-D-aspartate (NMDA) receptor antagonist and a sigma1 receptor agonist; it also increases serotonin neurotransmission in the brain.
Call your doctor if you experience any unusual problems while you are taking this medication. If you’re concerned about law enforcement getting involved, you don’t need to mention the substances used over the phone. Just be sure to tell them about specific symptoms so they can send the appropriate response.If you’re caring for someone else, get them to lay slightly on their side while you wait. Have them bend their top knee inward if they can for added support. This position will keep their airways open in case they begin to vomit. Taking more than the directed dose of DXM — or any medication for that matter — comes with severe risks.
Dextromethorphan Cost
- DXM causes different stages (often referred to as plateaus) that vary with dosage.
- People at this stage feel talkative, energetic, and euphoric.
- When DXM is abused regularly it can actually cause symptoms that are the opposite of the user’s intent such as insomnia and dysphoria (unease, unhappiness).
- One example is Auvelity, which contains dextromethorphan and bupropion.
- In susceptible individuals, DXM can cause allergic reactions due to its histamine-releasing properties.
Most of these side effects may go away within a few days to a couple of weeks. However, if they become more severe or don’t go away, talk with your doctor or pharmacist. But if you do find evidence of abuse, it may be time for a talk with your child. Here’s some guidance on what to do before you confront your son or daughter about OTC cough medicine abuse. You may also overhear your teen using or see them texting terms such as “skittles,” “robo-tripping,” “triple-C,” or “dexing.” These words are some of the many terms for cough medicine abuse.
Can Dextromethorphan Be Taken During The Night?
You will typically begin to notice the effects of DXM anywhere from 15 minutes to an hour after taking your first dose. If you’re taking between 10 and 30 mg, it should help suppress your cough for anywhere from about 4 to 6 hours. While Benadryl will often make you sleepy, DXM will typically only have this side effect if it is taken in very high doses or if it is used in combination with other types of medicines.
This section describes some of the more common side effects dextromethorphan may cause. Dextromethorphan belongs to a group of drugs called cough suppressants. People who misuse DXM take large doses to experience a high. This can be dangerous and lead to serious side effects, such as coma, psychosis, or death. A major metabolic catalyst involved is the cytochrome P450 enzyme known as 2D6, or CYP2D6.
This plateau is very intense — producing extreme states of dissociation or delirium similar to PCP. The effects last a very long time too — often exceeding several hours, with persistent effects lasting up to two weeks. Double-check the potency of the DXM you’re using, and look for the addition of other compounds such as acetaminophen which can cause severe liver-toxic side-effects at this dose.

Can Dextromethorphan Be Taken For Depression?
This is because many of the cough and cold medicines contain other active ingredients. This includes guaifenesin, acetaminophen, and chlorpheniramine, all of which can be toxic or fatal when taken in large amounts. DXM is a semisynthetic antitussive medication found in hundreds of over-the-counter cold medications around the world. It is best known by its trade name, Robitussin, but is commonly found in other cough medicines such as Nyquil, Benylin DM, Coricidin Cough and Cold, and many more. Among other mechanisms of action, DXM and its major metabolite dextrorphan produce its dissociative effects by antagonizing the glutamatergic NMDA receptor. Before taking dextromethorphan with other OTC cough, cold, or flu medications, be sure to check the ingredients of these products.
Respiratory Depression
If you are taking the liquid, do not use a household spoon to measure your dose. Use the measuring spoon or cup that came with the medication or use a spoon made especially for measuring medication. DXM interferes with your body’s ability to regulate temperature and can cause your body temperature to spike dangerously high. If you’re feeling really out of it and nauseous, sit upright in a comfortable chair instead of lying down in case you throw up. Hallucinations tend to occur at doses far above the normal range, as total daily doses of around 250–400 mg or more can trigger them.
What Are The Dosages Of Dextromethorphan?
It’s not known whether dextromethorphan is safe to take during pregnancy. If you’re sexually active and you or your partner can become pregnant, talk with your doctor about your birth control needs while you’re taking dextromethorphan. Here’s a rundown of some common terms for cough medicine abuse. If you take that much and then get very active, your body can overheat, and you might get a dangerously high fever. This is especially a problem for teens who go to dance clubs, where they can be sold DXM which looks like illegal club drugs such as PCP. When you take DXM with other drugs or alcohol, it raises the odds of trouble.

This effect explains the euphoric effects of DXM, especially in the 1st and 2nd plateau of effects. The psychedelic effects of DXM work through a similar mechanism to other dissociative drugs like ketamine and PCP. It’s a dissociative, which means it disconnects conscious thought from reality. It can force the mind into a state of altered reality and dissolve the concept of self vs. others. DXM isn’t the active ingredient; it’s a prodrug for dextrorphan — which is what produces the majority of the effects of the drug.

Things To Consider When Taking Dextromethorphan
People who misuse DXM describe different “plateaus” ranging from mild distortions of color and sound to visual hallucinations and “out-of-body” sensations, and loss of motor control. Combining dextromethorphan with other substances can compound risks. Central nervous system (CNS) stimulants such as amphetamine and/or cocaine can cause a dangerous rise in blood pressure and heart rate. CNS depressants such as alcohol will have a combined depressant effect, which can cause a decreased respiratory rate. In 2009, the National Institute on Drug Abuse’s Monitoring the Future Survey found that 6% of high school seniors had abused DXM. DXM abuse leads to approximately 6000 emergency room visits each year with half due to abuse by those aged 12 to 25 years.
In past decades, peer pressure to use drugs was a huge concern. It was thought that susceptible teens would be influenced by their peers in the neighborhood and at school. He had always been a moody kid, but his moodiness turned to anger, mania and psychosis. Over a four-month period, his father and mother took him to the emergency room four times.
