What Antibiotics Can You Take With Myasthenia Gravis

What Should I Know About Storage And Disposal Of This Medication

MHabibi: Myasthenia Gravis and Drug Interactions Antibiotics 1

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture .

It is important to keep all medication out of sight and reach of children as many containers are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location â one that is up and away and out of their sight and reach.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website for more information if you do not have access to a take-back program.

Make Your Home Easy To Live In

A few small changes can make homes easier to live in. Sofas and chairs should not be too low, making it difficult to get up. They should also have armrests to make it easier to get up or to act as support when standing. Objects that are often used, such as eyeglasses and keys, should be placed in a prominent, easy-to-access place all the time.

Guidance For Antibiotic Use In Patients With Myasthenia Gravis

All prescribers should be aware of the range of possible adverse effects associated with antibiotics. Though perhaps less well recognized than other adverse effects, various neurotoxicities including seizure, optic neuropathy, encephalopathy, peripheral neuropathy, and exacerbation of myasthenia gravis may result from antibiotic use.1 This risk is increased in older patients, patients with impaired renal function, and patients with preexisting neurologic conditions.1

Infection and Myasthenia Gravis

The potential for antibiotics to unmask or worsen MG is particularly significant given that patients with MG may be predisposed to acquiring infectious diseases. Possible factors that could contribute to an increased risk for infection include an autoimmune disease process, muscle weakness, and possible immunosuppressive treatments.3 Most patients with MG require immunosuppressive medication such as prednisone, azathioprine, mycophenolate mofetil, or rituximab.4 Additionally, approximately 15% of patients with MG have a second autoimmune disease such as lupus or rheumatoid arthritis, which may also require immunosuppressive medications.4 Currently available immunosuppressive medications used in MG broadly suppress immune reactivity, including the ability to react against microbes.3 While the exact increase in rate of infection is not known, it is estimated that the risk for infection while on corticosteroids increases 20% to 50%.3

Plasmapheresis And Intravenous Immunoglobulin

In plasmapheresis, also known asplasma exchange, an intravenous line is used to remove antibodies from the blood. IVIG therapy is essentially an injection of a nonspecific antibody that might dial down the immune systems production of its own antibodies, much as warm air tells a thermostat to stop pumping out heat.

These treatments bring about fast but short-lived relief from MG, and are mostly used until other medications take effect, prior to surgery or for myasthenic crisis. However, some people receive regular plasmapheresis or IVIG as a supplement to immunosuppressant drugs.

Plasmapheresis is not commonly used as a long-term treatment as each treatment requires five plasma exchanges over the course of one or two weeks. This need for repeated exchanges often leads to issues with venous access.

What Is Myasthenia Gravis


Myasthenia gravis is an autoimmune disorder characterized by fluctuating muscle weakness that worsens with exertion and improves with rest. Myasthenia gravis is a rare condition. About two in every 10,000 people live with the condition. Most experience only mild or moderate symptoms.

The weakness concentrates on one or more muscle groups, typically the eyes and eyelids. However, the jaw muscles, throat, upper extremities , and, in some cases, the respiratory muscles are affected

Like other autoimmune disorders, the symptoms of myasthenia gravis are caused by an overactive immune system. The body mistakenly produces antibodies that attach to receptors at the neuromuscular junction, the place where nerves pass signals to muscle cells and stimulate muscle contractions. Nerves communicate to muscle cells through a chemical called acetylcholine, but the antibodies attack the receptors that allow these signals to get through. Weakened nerve signals cause the fluctuating weakness typical of myasthenia gravis.

Several types of autoantibodies cause myasthenia gravis, named after the receptor to which they attach: AChR antibodies, MuSK antibodies, or LRP4 antibodies. Symptoms and treatment will vary depending on the type of autoantibody causing the disease.

Finally, myasthenia gravis is classified based on the age of onset and the extent that it affects the body, either limited to the eyes or muscle groups elsewhere . Again, symptoms and treatment may vary.

Is It Safe For People With Mg

As of February 2021, the U.S. Food and Drug Administration has approved 2 COVID-19 vaccines for use in the United States. Both are mRNA vaccines from Pfizer-BioNTech and Moderna. This new type of vaccine teaches our cells how to make a protein that triggers an immune response, protecting us from a COVID-19 infection.5

Vaccines go through research studies called clinical trials. The FDA then reviews the data from clinical trials to figure out if a vaccine is safe and works well. Scientists have tested the COVID-19 vaccines on people with long-term illnesses and will continue to monitor how well they work in the real world.6,7

People with MG can get an mRNA COVID-19 vaccine. However, you should know that as of February 2021, there is no safety data on mRNA vaccines for those with autoimmune conditions. Researchers did allow people with autoimmune conditions to enroll in vaccine clinical trials, but specific safety data on this group is not yet available.8

There is no evidence that the COVID-19 vaccines interact with other medicines like immunosuppressants or other drugs. But, just to be safe, tell your vaccine provider about any medicines you take.9

Myasthenia Gravis Treatment Options

Myasthenia gravis is an autoimmune disorder that cannot be cured. The goal of long-term treatment is to achieve a partial or total remission of symptoms with the least amount of unwanted side effects. This is achieved by drugs that increase the ability of nerves to pass signals to the muscles, drugs that suppress the immune system, or surgery to remove an overactive thymus. Emergency treatment for a myasthenic crisis involves plasma exchange or intravenous immunoglobulins to rapidly remove autoantibodies and relieve symptoms.

How Is Myasthenia Gravis Diagnosed

Alzheimer’s, Myasthenia Gravis, Parkinson’s Medications – Pharmacology – Nervous

Myasthenia gravis is diagnosed mainly from the symptoms and patients history, but testing is required to determine the type and severity of the condition. Testing, final diagnosis, and treatment will primarily be managed by a neurologist.

The characteristic symptom of myasthenia gravis is weakness that comes and goes, gets worse with exertion or repetitive activities, and improves with rest.

Other typical symptoms depend on which muscle groups are affected and include:

  • Blurred vision
  • Expressionless face or drooping head
  • Weak upper arms or legs
  • Difficulty breathing

Because myasthenia gravis is diagnosed by the type of autoantibodies attacking the neuromuscular junctions, blood tests will be required to identify those antibodies. In patients who do not have myasthenia gravis autoantibodies, other tests may be required:

A CT scan of the chest will be performed if the doctor suspects cancer of the thymus gland

Potential For Negative Reactions

The antibiotics that are most likely to worsen MG are usually given in the hospital to treat very serious infections. For example, some drugs like telithromycin have a boxed warning in their prescribing information that lets doctors know that people with MG should not take them.1-5

A list of antibiotics that people with MG should use with caution is included at the end of this article. While some of these are well known to interfere with MG, some may be used with a doctors supervision if your MG is well controlled. Just be sure to tell your doctor if you notice your MG symptoms getting worse while you take these or any types of drugs.1-5

What Foods Help Myasthenia Gravis

As with all conditions, there are many claims that certain foods or nutrients help myasthenia gravis. While some people may experience symptom improvement by changing their diet, no food, nutrient, or diet has been proven to be clinically relevant in the treatment of myasthenia gravis. As with any health condition, the best diet is one that is healthy and rich in nutrients.

Gil Wolfe, MD, the Irvin and Rosemary Smith Professor and Chairman of Neurology at University at Buffalo. SUNY, and coauthor of the 2020 consensus guidance, said he sees several treatment trends emerging for MG.

The approach of many of us has changed in the last few years, whereby we try to be more aggressive with treatment earlier based on data suggesting that being aggressive at the time of disease diagnosis pays off dividends over time in terms of more favorable patient outcomes, he said.

He said there also is growing data that patients who reach certain favorable milestones earlier, such as within the first year or two after diagnosis, tend to have a more stable course long term, perhaps for decades, he said.

He predicts that another treatment approach that will become more common is the use of the newer drugs, such as eculizumab and efgartigimod, as bridge therapies.

These newer agents that work relatively quickly will be used to bridge patients while we await conventional oral therapies such as corticosteroids and the so-called steroid-sparing immunosuppressants, to take hold, he said.

Dr. Guidon said that as treatment options for MG continue to expand, it is going to become easier and easier to escalate treatment and we want to make sure the diagnosis is correct. She said that patients may be experiencing some symptoms not necessarily caused by MG, and it is important to establish whats in the myasthenia bucket and what is outside of it.

Why Is This Medication Prescribed

Levofloxacin is used to treat certain infections such as pneumonia, and kidney, prostate , and skin infections. Levofloxacin is also used to prevent anthrax in people who may have been exposed to anthrax germs in the air, and treat and prevent plague (a serious infection that may be spread on purpose as part of a bioterror attack. Levofloxacin may also be used to treat bronchitis, sinus infections, or urinary tract infections but should not be used for bronchitis and certain types of urinary tract infections if there are other treatment options available. Levofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections.

Antibiotics such as levofloxacin will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

The complications of myasthenia gravis can be divided into disease-related complications and treatment-related complications. As the condition is chronic and aggressive treatment strategy is required in some cases, certain complications occur due to treatment.

    Following are the various complications of myasthenia gravis:

    Disease Related Complications The symptoms of myasthenia gravis are normally managed with the administration of various medications. The disease is kept in the remission stage. However, in certain cases, the disease has complications, some of which are normal, but some are life-threatening.

  • Thymus Tumor Almost 15% of the patients suffering from myasthenia gravis also have a thymoma, a tumor of the thymus glands. The tumor is generally non-cancerous and can be treated with surgery.

    erectile dysfunction, azathioprine, pyridostigmine, medicine, male

    I am 60 yrs old male and am taking medicine for ‘myesthenia gravis’. I am on basically 3 drugs 1) pyridostigmine – 4 tablets 2)azathioprine – 3 tablets and 3) prednislone 25 mg per day. I have no erection. Can I take viagra or cialis for sexual satisfaction. Anyone please let me know.


    Your best bet would be to talk to your primary physician or to a urologist since none of us on here can tell you if you are healthy enough for sex.


    I am also a 60 year old male diagnosed with myasthenia gravis. I have a fairly manageable case that has improved somewhat over the last few years by reducing stress and more sleep as a result of retirement. Both Viagra and levitra had huge reactions for my m.g. and severely increased my symptoms within a couple of hours and had noticeable lasting but reducing effects for several days. I highly recommend extreme caution based on my personal experience. I reported this to the manufacturer of Viagra who was very interested and who stated they had not tested on anyone with m.g. due to testing protocol and the rarity of the affliction.
