Cefoxitin and Weed


Most people who consume marijuana do so for its mood-altering and relaxing abilities. Weed gives people a high and allows them to relax. However, heavy consumption of weed can cause unwanted results. It can increase the anxiety and depression a person experiences, and it can interact with certain other drugs including Cefoxitin. It is important to remember that interactions do occur with all types of drugs, to a great or lesser extent and this article details the interactions of mixing Cefoxitin and Weed.


Mixing Cefoxitin and Weed


Cefoxitin is a second-generation cephamycin antibiotic developed by Merck & Co., Inc. from Cephamycin C in the year following its discovery, 1972. It was synthesized in order to create an antibiotic with a broader spectrum. It is often grouped with the second-generation cephalosporins. Cefoxitin requires a prescription and as of 2010 is sold under the brand name Mefoxin by Bioniche Pharma, LLC. The generic version of cefoxitin is known as cefoxitin sodium.

Groups of researchers at Merck and Lilly discovered Cephamycin C while looking at penicillin-producing bacteria. This followed their discovery of erythromycin, another antibiotic. Cephamycin C was the first cephem discovered but while it was highly resistant to several beta-lactamases, as is its derivative cefoxitin, it was almost only effective against Gram negative bacteria. The scientists used chemically modified the compound to give cefoxitin, so titled due to its semi-synthetic nature. This new modification broadened its spectrum to include Gram positive bacteria. More than 300 modifications were made to it and tested on the cephalosporin base with methoxy groups at the 7-alpha position. Yet only cefoxitin retained its previous effectiveness against Gram negative bacteria, developed effectiveness against Gram positive bacteria, and resisted breakdown by beta-lactamase.

Cefoxitin, and the cephamycin family as a whole, served as a branching point and impulsed the discovery of more classes of beta-lactams. This is in part due to their primary and early discovery in the broths studied.

Cefoxitin is a beta-lactam antibiotic which binds to penicillin binding proteins, or transpeptidases. By binding to PBPs, cefoxitin prevents the PBPs from forming the cross-linkages between the peptidoglycan layers that make up the bacterial cell wall, thereby interfering with cell wall synthesis. It is a strong beta-lactamase inducer, as are certain other antibiotics (such as imipenem). However, cefoxitin is a better substrate than imipenem for beta-lactamases.

In the presence of cefoxitin, bacteria that make beta-lactamases will increase their production and secretion to cleave the beta lactam ring. As a cephamycin, cefoxitin is highly resistant to hydrolysis by some beta-lactamases, in part due to the presence of the 7-alpha-methoxy functional group (see skeletal formula above).

Another more efficient form of resistance to cefoxitin is provided by the mecA gene in bacteria. This gene codes for an alternative penicillin binding protein, PBP2a. This PBP has a lower binding affinity for penicillin-based antibiotics such as cefoxitin and will continue to cross-link the peptidoglycan layers of the cell wall even in the presence of the beta-lactam antibiotics. MRSA, or methicillin-resistant Staphylococcus aureus is a strain that has acquired resistance to cefoxitin via this gene. For the purposes of detecting bacterial strains with the mecC gene, which like mecA codes for a different PBP, cefoxitin is more reliable than oxacillin because mecC does not correlate as strongly with oxacillin resistance.

Cefoxitin’s spectrum of in vitro antimicrobial activity includes a broad range of gram-negative and gram-positive bacteria, including anaerobes. It is inactive against most strains of Pseudomonas aeruginosa and many strains of Enterobacter cloacae. Staphylococci that are resistant to methicillin and oxacillin should also be considered clinically resistant to cefoxitin even if they test susceptible by in vitro methods.

Major bacterial strains susceptible to cefoxitin include:

Major bacteria resistant to cefoxitin include:

In a 2005 study, Fernandes et al. determined that cefoxitin serves as an appropriate replacement for methicillin in determining if some bacteria display methicillin resistance. Likewise, Funsun et al. found in a 2009 study that cefoxitin disk assays correctly identified all 60 mecA-positive Staphylococcus aureus, or MRSA isolates, to be resistant to cefoxitin.

Due, in part, to the unavailability of methicillin in the United States, cefoxitin has replaced methicillin for disk diffusion tests, which determine the sensitivity of a bacterial specimen to a given antibiotic. Cefoxitin also yields more accurate results for disk diffusion tests. Interpretive criteria for determining susceptibility to cefoxitin via disk diffusion are greater than or equal to 22mm resulting in a “susceptible” result for Staphylococcus aureus and greater than or equal to 25mm for coagulase-negative staphylococci to be considered susceptible.

The following are susceptibility data for several medically significant microorganisms, measured by minimum inhibitory concentration, which is an alternative, liquid medium test for susceptibility.

Cefoxitin is sold in three major IV doses, 1g, 2g, and 10g. It is usually given to adults every six to eight hours in 1g or 2g doses. Cefoxitin may interfere with tests detecting urine glucose and result in a false positive. As with any antibiotic, it should not be given to patients who are allergic to it.

Cefoxitin is used to treat:

Cefoxitin has many other uses; it may be given prior to surgery to prevent the development of surgical wound infections, and when used in third and fourth degree perineal injuries in women after giving vaginal birth, cefoxitin decreases infection rate at two and six weeks. However, the earlier and more times a child is exposed to cefoxitin, as with early and multiple exposure to many antibiotics, the greater the likelihood of developing inflammatory bowel disease later in life. This may be due in part to a decreased variety of microorganisms in the digestive system.

It is also used to treat pelvic inflammatory disease, because it is a broad spectrum antibiotic. For outpatient treatment, oral antibiotics or those with less frequent dosing may be prescribed. As an effective alternative to penicillin and spectinomycin, and replacement for methicillin, cefoxitin is used to treat gonorrhea in both men and women with few side effects.

Side effects for cefoxitin are regarded as mild. Common side effects include:

While cefoxitin has not been associated with alcohol incompatibility like other members of the second generation cephalosporins class, it has been with a higher risk of coagulopathy, a bleeding disorder.

This is not a comprehensive list and not intended to provide medical advice. If any of the previous side effects are severe, or if an allergic reaction takes place immediately contact your doctor.

A contraindication means that the drug in question should not be used under particular circumstances. For cefoxitin, this includes patients who are hypersensitive to cephalosporin antibiotics.

Patients with colitis, kidney disease, or liver disease are also advised not to take cefoxitin. However, some drug databases will considers the diseases means for caution rather than contraindications.

Aside from the above-mentioned contraindications and diseases which require monitoring by a doctor, the live cholera and live typhoid vaccines are known to have a severe interaction with cefoxitin.

Individuals on a low sodium diet, undergoing dialysis, or who have experienced seizures, particularly following antibiotic therapy, should also consult their physician prior to taking cefoxitin.

Only take additional antibiotics, anticoagulants and blood thinners under doctor supervision. Cefoxitin may decrease the effectiveness of hormonal birth control. This increases the risk for pregnancy and a medical consult will help determine whether backup birth control methods should be used.

Minor drug interactions do not usually require a change in treatment. Your doctor may monitor specific events, such as bleeding, while taking cefoxitin. Two such minor interactions occur between cefoxitin and heparin as well as genistein.

Pharmocokinetic and pharmacodynamic data for cefoxitin are, as of 2013, considered limited and outdated. A few relatively recent studies have attempted to remedy that.

One such study was by the Hôpitaux de Paris in collaboration with the French Ministry of Health. However, while the clinical trials were completed in 2015, no study data have been published. The expected results from using cefoxitin over carbapenems, another type of antibiotic with a wider bacterial spectrum, included effective treatment of E. coli produce extended spectrum beta-lactamase, less selective pressure on the GI tract which better maintains balanced flora, and a lower treatment cost.

This followed a 2012 French study on the same E. coli strain with CTX-M-15 extended release beta-lactamase. Lepeule et al. determined that in mice, the ideal pharmacodynamic target of fT>MIC=33%, where MIC is the minimum inhibitory concentration, was obtained with 200 mg/kg every four hours. The fT>MIC (%) was increased by 11% when the administration frequency was increased from every four hours to every three hours. This implied that increasing the frequency might yield similar results in humans. The study also found no significant difference between the effectiveness of carbapenems and cefoxitin and suggested that cefoxitin can be used as an alternative treatment for CTX-M producing E. coli to carbapenems such as imipenem and ertapenem.


Research has found that anxiety is one of the leading symptoms created by marijuana in users, and that there is a correlation between Cefoxitin and Weed and an increase in anxiety.


Anyone mixing Cefoxitin and weed is likely to experience side effects. This happens with all medications whether weed or Cefoxitin is mixed with them. Side effects can be harmful when mixing Cefoxitin and weed. Doctors are likely to refuse a patient a Cefoxitin prescription if the individual is a weed smoker or user. Of course, this could be due to the lack of studies and research completed on the mixing of Cefoxitin and Weed.


Heavy, long-term weed use is harmful for people. It alters the brain’s functions and structure, and all pharmaceuticals and drugs including Cefoxitin are designed to have an impact on the brain. There is a misplaced belief that pharmaceuticals and medication work by treating only the parts of the body affected yet this is obviously not the case in terms of Cefoxitin. For example, simple painkiller medication does not heal the injury, it simply interrupts the brains functions to receive the pain cause by the injury. To say then that two drugs, Cefoxitin and Weed, dol not interact is wrong. There will always be an interaction between Cefoxitin and Weed in the brain11.J. D. Brown and A. G. Winterstein, Potential Adverse Drug Events and Drug–Drug Interactions with Medical and Consumer Cannabidiol (CBD) Use – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6678684/.


One of the milder side effects of mixing Cefoxitin and Weed is Scromiting. This condition, reportedly caused by mixing Cefoxitin and Weed, describes a marijuana-induced condition where the user experiences episodes of violent vomiting, which are often so severe and painful that they cause the person to scream. The medical term for Scromiting by mixing Cefoxitin and Weed is cannabinoid hyperemesis syndrome, or CHS.  For these reasons, some people choose to quit smoking weed.


It was first included in scientific reports in 2004. Since then, researchers have determined that Scromiting is the result of ongoing, long-term use of marijuana—particularly when the drug contains high levels of THC, marijuana’s main psychoactive ingredient. Some experts believe that the receptors in the gut become overstimulated by THC, thus causing the repeated cycles of vomiting.


In the long run, a person can become even more depressed. There is a belief that marijuana is all-natural and not harmful to a person’s health. This is not true and Cefoxitin and weed can cause health issues the more a person consumes it.


How does Weed effect the potency of Cefoxitin?


The way in which the body absorbs and process Cefoxitin may be affected by weed. Therefore, the potency of the Cefoxitin may be less effective. Marijuana inhibits the metabolization of Cefoxitin. Not having the right potency of Cefoxitin means a person may either have a delay in the relief of their underlying symptoms.


A person seeking Cefoxitin medication that uses weed should speak to their doctor. It is important the doctor knows about a patient’s weed use, so they can prescribe the right Cefoxitin medication and strength. Or depending on level of interactions they may opt to prescribe a totally different medication. It is important for the doctor to know about their patient’s marijuana use. Weed is being legalized around the US, so doctors should be open to speaking about a patient’s use of it.


Sideffects of Cefoxitin and Weed


Many individuals may not realize that there are side effects and consequences to mixing Cefoxitin and Weed such as:


  • Dizziness
  • Sluggishness
  • Drowsiness
  • Shortness of breath
  • Itching
  • Hives
  • Palpitations
  • Respiratory Depression
  • Cardiac Arrest
  • Coma
  • Seizures
  • Death


Interestingly, it is impossible to tell what effect mixing this substance with Weed will have on an individual due to their own unique genetic make up and tolerance. It is never advisable to mix Cefoxitin and Weed due to the chances of mild, moderate and severe side effects. If you are having an adverse reaction from mixing Cefoxitin and Weed it’s imperative that you head to your local emergency room. Even mixing a small amount of Cefoxitin and Weed is not recommended.


Taking Cefoxitin and Weed together


People who take Cefoxitin and Weed together will experience the effects of both substances. Technically, the specific effects and reactions that occur due to frequent use of Cefoxitin and weed depend on whether you consume more weed in relation to Cefoxitin or more Cefoxitin in relation to weed.


The use of significantly more weed and Cefoxitin will lead to sedation and lethargy, as well as the synergistic effects resulting from a mixture of the two medications.


People who take both weed and Cefoxitin may experience effects such as:


  • reduced motor reflexes from Cefoxitin and Weed
  • dizziness from Weed and Cefoxitin
  • nausea and vomiting due to Cefoxitin and Weed


Some people may also experience more euphoria, depression, irritability or all three. A combination of weed and Cefoxitin leads to significantly more lethargy which can easily tip over into coma, respiratory depression seizures and death.

Mixing weed and Cefoxitin


The primary effect of weed is influenced by an increase in the concentration of the inhibitory neurotransmitter GABA, which is found in the spinal cord and brain stem, and by a reduction in its effect on neuronal transmitters. When weed is combined with Cefoxitin this primary effect is exaggerated, increasing the strain on the body with unpredictable results.


Weed and Cefoxitin affects dopamine levels in the brain, causing the body both mental and physical distress. Larger amounts of Cefoxitin and weed have a greater adverse effect yet leading medical recommendation is that smaller does of Cefoxitin can be just as harmful and there is no way of knowing exactly how Cefoxitin and weed is going to affect an individual before they take it.


Taking Cefoxitin and weed together


People who take Cefoxitin and weed together will experience the effects of both substances. The use of significantly more Cefoxitin with weed will lead to sedation and lethargy, as well as the synergistic effects resulting from a mixture of the two medications.


People who take both weed and Cefoxitin may experience effects such as:


  • reduced motor reflexes from Cefoxitin and weed
  • dizziness from weed and Cefoxitin
  • nausea and vomiting of the Cefoxitin


Some people may also experience more euphoria, depression, irritability or all three. A combination of weed and Cefoxitin leads to significantly more lethargy which can easily tip over into coma, respiratory depression seizures and death.

Weed Vs Cefoxitin


Taking Cefoxitin in sufficient quantities increases the risk of a heart failure. Additionally, people under the influence of Cefoxitin and weed may have difficulty forming new memories. With weed vs Cefoxitin in an individual’s system they become confused and do not understand their environment. Due to the synergistic properties of Cefoxitin when mixed with weed it can lead to confusion, anxiety, depression and other mental disorders. Chronic use of Cefoxitin and weed can lead to permanent changes in the brain22.G. Lafaye, L. Karila, L. Blecha and A. Benyamina, Cannabis, cannabinoids, and health – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5741114/.


Cefoxitin Vs Weed


Studies investigating the effects of drugs such as Cefoxitin and weed have shown that the potential for parasomnia (performing tasks in sleep) is dramatically increased when Cefoxitin and weed are combined. Severe and dangerous side effects can occur when medications are mixed in the system, and sleep disorders are a common side effect of taking weed and Cefoxitin together.


When a small to medium amount of weed is combined with Cefoxitin, sleep disorders such as sleep apnea can occur. According to the latest data from the US Centers for Disease Control and Prevention (CDC) most ER visits and hospitalizations caused by too much weed were associated with other substances such as Cefoxitin.


How long after taking Cefoxitin can I smoke weed or take edibles?


To avoid any residual toxicity it is advisable to wait until the Cefoxitin has totally cleared your system before taking weed, even in small quantities.


Overdose on Cefoxitin and weed


In the case of Overdose on Cefoxitin or if you are worried after mixing Cefoxitin and weed, call a first responder or proceed to the nearest Emergency Room immediately.


If you are worried about someone who has taken too much Cefoxitin or mixed weed with Cefoxitin then call a first responder or take them to get immediate medical help. The best place for you or someone you care about in the case of a medical emergency is under medical supervision. Be sure to tell the medical team that there is a mix of Cefoxitin and weed in their system.


Excessive Weed intake and result in scromiting, chs, and anxiety disorder.  It is advisable to quit vaping weed if you are feeling these symptoms.

Mixing Cefoxitin and weed and antidepressants


Weed users feeling depressed and anxious may be prescribed antidepressant medication. There are some antidepressant users who also use Cefoxitin and weed. These individuals may not realize that there are side effects and consequences to consuming both Cefoxitin, marijuana and a range of antidepressants.


Studies on weed, Cefoxitin and antidepressants is almost nil. The reason for so little information on the side effects of the two is mostly down to marijuana being illegal in most places – although a number of states in the United States have legalized the drug.


Self-medicating with Weed and Cefoxitin


A lot of people suffer from depression caused by weed and Cefoxitin. How many? According to Anxiety and Depression Association of America (ADAA), in any given year, it is estimated that nearly 16 million adults experience depression. Unfortunately, that number is likely to be wrong due to under reporting. Many people do not report suffering from depression because they do not want to be looked at as suffering from a mental illness. The stigmas around mental health continue and people do not want to be labeled as depressed.


Potential side effects from mixing Cefoxitin and weed


Quitting weed to take Cefoxitin


Medical professionals say an individual prescribed or taking Cefoxitin should not stop using weed cold turkey.  Withdrawal symptoms can be significant. Heavy pot users should especially avoid going cold turkey. The side effects of withdrawal from weed include anxiety, irritability, loss of sleep, change of appetite, and depression by quitting weed cold turkey and starting to take Cefoxitin.


A person beginning to use Cefoxitin should cut back on weed slowly. While reducing the amount of weed use, combine it with mindfulness techniques and/or yoga. Experts stress that non-medication can greatly improve a person’s mood.


Weed and Cefoxitin can affect a person in various ways. Different types of marijuana produce different side effects. Side effects of weed and Cefoxitin may include:


  • loss of motor skills
  • poor or lack of coordination
  • lowered blood pressure
  • short-term memory loss
  • increased heart rate
  • increased blood pressure
  • anxiety
  • paranoia
  • increased energy
  • increased motivation


Mixing Cefoxitin and weed can also produce hallucinations in users. This makes marijuana a hallucinogenic for some users. Weed creates different side effects in different people, making it a very potent drug. Now, mixing Cefoxitin or other mental health drugs with weed can cause even more unwanted side effects.


Mixing drugs and weed conclusion


Long-term weed use can make depression and anxiety worse. In addition, using marijuana can prevent Cefoxitin from working to their full potential33.J. D. Brown and A. G. Winterstein, Potential Adverse Drug Events and Drug–Drug Interactions with Medical and Consumer Cannabidiol (CBD) Use – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6678684/. Weed consumption should be reduced gradually to get the most out of prescription medication. Marijuana is a drug and it is harmful to individual’s long-term health. Weed has many side effects and the consequences are different to each person who uses it, especially when mixed with Cefoxitin.
