The prescribing information for Wellbutrin states that the use of alcohol (all types of alcohol including beer, wine, and liquor) should be avoided if possible or at least minimized. Common ones include the EIA (Enzyme Linked Immunoassay) test and the CEDIA (Closed Enzyme Donor Immunoassay) test. When a specified drug is present wellbutrin uses and precautions in a test urine sample, an antibody binds to it and produces a reaction.
Answer
However, increased levels of serotonin often have blood thinning effects and can increase the risk of dangerous bleeding events. A study has found that the incidence of seizures was found in 0.4% of patients treated with bupropion at doses up to 450 mg a day. This risk is increased ten fold at doses between 450 mg and 600 mg a day. Another study tested the seizure threshold in mice with alcohol and administration of bupropion, revealing as high as a 3.5 fold increase of seizures. Wellbutrin is unrelated to other antidepressant medications and the exact mechanism of action is unclear. It thought to work by increasing the amount of the dopamine in the brain, but the antidepressant effects of the drug are known to occur at doses below what is needed to have a significant effect on dopaminergic systems.
In regard to the interaction mentioned, there is a minor one that needs to be considered if you and your doctor are looking to combine the two drugs. Wellbutrin may increase the concentrations of Celexa in the body and a minor dose adjustment to Celexa may be necessary. One study showed the concentration of Celexa increased by 30% when taken with Wellbutrin, so care must be taken when using both together. So while inhibition of CYP2B6, as discussed above, will increase levels of bupropion, levels of hydroxybupropion are decreased since less bupropion is being metabolized (i.e. converted to) hydroxybupropion.
SSRI & Jaw Clenching
Bupropion is contraindicated in patients with seizure disorder, as well as patients undergoing abrupt discontinuation of alcohol. Be sure to talk to your about about this possible therapy option so you can have the appropriate prescribed doses of each. In addition to its use as an antidepressant, it also is used for smoking cessation (Zyban) and seasonal affective disorder. It is unrelated to other antidepressants (such as SSRIs and SNRIs), both structurally and mechanistically. In the next sections, I discuss Wellbutrin XL and its effects on weight in more detail.
Since bupropion is the most potent and active of the compounds in regard to effect, the net result of the interaction between Wellbutrin in Plavix is generally agreed to be an overall increase in effect. Therefore, there may be a need to decrease the dose of Wellbutrin in some individuals to avoid side effects. Nevertheless, treatment of depression alone can’t be the only factor since other antidepressants classes (e.g. SSRIs) so often cause an increase in weight. First and foremost, it appears the effective treatment of depression is a major factor.
- Another study, that specifically looked at the combination of Wellbutrin and Celexa, had similar results.
- Effectively treating it can help individuals return to a more healthy lifestyle and weight.
- This risk is increased ten fold at doses between 450 mg and 600 mg a day.
- In general, it is recommended to slowly taper antidepressant drugs over at least a few weeks when discontinuing them.
What Is Wellbutrin XL?
Most people started having symptoms within the first few weeks of SSRI therapy and patients gained relief after the dose of the offending SSRI was decreased. Studies suggest that SSRI-induced increase in serotonin acted to reduce dopamine levels in areas of the brain where it acts to inhibit certain movements including bruxism. They theorize that SSRIs increase serotonin in the mesocortical tract, which inhibits the release of dopamine.
What Is The Best Time Of Day To Take Zoloft (Sertraline)?
It is important to note that while bupropion concentrations can be increased when taking in conjunction with Plavix, hydroxybupropion can be decreased. In our latest question and answer, the pharmacist discusses whether or not there is an interaction between Wellbutrin (bupropion) and Plavix (clopidogrel). As stated at the outset, Wellbutrin is more likely to cause weight loss than weight gain. It is thought to work mainly by inhibiting the neuronal reuptake of dopamine, but this effect may only happen at doses higher than what is needed to effectively treat depressive symptoms. It also appears to inhibit the reuptake of norepinephrine and has a mild CNS (central nervous system) stimulating effect.
For Individuals
In other words, they feel the effects of alcohol more quickly when taking the drug.10This is certainly something to be aware of and look out for. Due to the increased risk of seizures with Wellbutrin, it is contraindicated (i.e. should not be used) in those with a seizure disorder. Another study, that specifically looked at the combination of Wellbutrin and Celexa, had similar results. The combination was more effective than either drug alone and there was not an increased incidence of side effects.
Wellbutrin SR is another extended-release version bupropion, but is generally dosed twice-daily (versus the once-daily dosing of Wellbutrin XL) and comes in different strengths. It is odd thought that the drug Wellbutrin (which you are also taking) acts to INCREASE dopamine. Even though it increases dopamine, bruxism is a listed side effect of Wellbutrin as well. They also seemed to respond to the addition of a drug known as Buspar (buspirone). There is no known drug interaction between Benadryl (diphenhydramine) and Wellbutrin XL (bupropion extended-release).
- It does appear to be dose related meaning that higher doses increase the risk of occurrence.
- In the next sections, I discuss Wellbutrin XL and its effects on weight in more detail.
- An interesting note is that some individuals taking Wellbutrin have reported that their tolerance to alcohol is decreased when taking Wellbutrin.
- It also appears to inhibit the reuptake of norepinephrine and has a mild CNS (central nervous system) stimulating effect.
Does Wellbutrin XL Cause Weight Gain?
Bupropion and the 3 metabolites listed above are all active in terms of their pharmacologic effects, although bupropion is the most potent. The prescribing information for Wellbutrin XL also gives us weight change data on another formulation of bupropion, Wellbutrin SR. It’s always tough to exactly pin down why side effects are happening but there is a good chance your problems may be stemming from some of the medications you are taking. Our pharmacist answers the latest question regarding what to do if your SSRI causes jaw clenching. Our pharmacist answers the latest question regarding a potential interaction between Wellbutrin (Buproprion) and Benadryl (Diphenhydramine).
Is There An Interaction Between Wellbutrin XL And Benadryl?
In this tract dopamine acts to inhibit motor activity including that for jaw muscles. Reducing dopamine levels would thus reduce this inhibitory effect and allow the development of bruxism. It is sometimes difficult to choose a safe and effective antidepressant medication for individuals who are also taking a blood thinner.
This applies to all drug products containing bupropion, which includes Wellbutrin XL, Wellbutrin SR (bupropion sustained-release) and Zyban (bupropion sustained-release). The 0.4% incidence rate of seizures is for the immediate-release formulations of Wellbutrin. There is some concern with mixing alcohol, including beer, with Wellbutrin (bupropion). Often times, drugs that are NOT being tested for can react with the wrong antibody (i.e. ‘cross react’), resulting in a ‘false positive’.
