Pregabalin for long COVID
PREGABALIN
What is pregabalin?
Pregabalin is a medication that mimics gamma-aminobutyric acid (GABA) in the body. GABA is responsible for inhibiting neurons that produce an excitatory signal. In pain or seizures, neurons constantly fire, inducing an excitatory response. GABA works to calm these neurons and return them to normalcy. Pregabalin is commonly used for neuropathy (nerve pain) and those affected with partial seizures [1]. It is a controlled substance (C-V) and does have the potential for abuse if taken differently than prescribed.
Can pregabalin help with long-COVID?
Patients with long-COVID can display a variety of symptoms such as tremors or neuropathy in the fingers or toes. Although the mechanism behind this is still unclear, some theories point to damage of the nerve cells by COVID-19, causing an imbalance in excitatory versus inhibitory neurons [2]. Several providers have turned to therapies, such as pregabalin, to control these symptoms. In a guide created for primary care physicians regarding long-COVID, the use of pregabalin is warranted for neuropathic pain [2]. Additionally, a review study published in 2022 found that in patients with neuropathy from long-COVID, 61% were prescribed agents such as pregabalin for symptom management [3].
Pregabalin may be a helpful therapy for those suffering from neurological pain associated with long-COVID. It may offer symptom management and help restore a patient to pre-COVID baseline function.

EndeavorRx for long COVID
BRAIN TRAINING PROGRAMS: EndeavorRx
What are brain training programs like EndeavorRx?
EndeavorRx is an FDA-authorized video game to improve attention function in children ages 8-12 with ADHD. The program can be considered part of a treatment plan combined with provider-directed therapy, medication, and educational programs. EndeavorRx is prescribed by a provider and is currently priced at $99 for a 30-day prescription and FSA/HSA eligible.1
Like EndeavorRx, EndeavorOTC is a similar video game app clinically designed to improve adult ADHD symptoms. The game tests your ability to see a target and navigate a course to avoid obstacles. It is recommended to be played for six weeks intervals followed by a one-week break.2
How can brain training programs like EndeavorRx help alleviate certain long COVID symptoms?
Cognitive symptoms of long COVID include brain fog (trouble thinking clearly or remembering) and difficulty focusing on tasks. The SARS-CoV-2 virus can directly infect the central nervous system and damage brain tissue, which is hypothesized to lead to cognitive impairment. In addition, the virus possesses a spike protein that studies have associated with memory loss after COVID.3 EndeavorRx and EndeavorOTC can improve attention in long COVID patients.
What evidence supports using brain training programs like EndeavorRx for long COVID?
EndeavorRx is supported by five clinical studies that included more than 600 children with ADHD. The company’s randomized controlled trial found that the program improved objective attention in children when played for about 25 minutes a day, five days per week, for four weeks, with added benefits in a second month of treatment.4
EndeavorOTC was studied in adults with ADHD, with 73% of participants reporting quality of life improvements. This study found that 60% were better able to complete projects on time, and 53% were better able to manage multiple tasks at once.5
EndeavorRx and EndeavorOTC are currently being studied at Cornell New York Presbyterian and Vanderbilt for use in long COVID patients with cognitive impairment.6
What are some things to watch out for with brain training programs like EndeavorRx?
No serious adverse events have been reported. About 9% of participants reported a treatment-related adverse event such as frustration, headache, dizziness, emotional reaction, nausea, and aggression. All adverse events were transient, and only three led to discontinuation of the program.1

Maraviroc for long COVID
MARAVIROC
What is maraviroc (Selzentry)?
Maraviroc is a medication used to treat human immunodeficiency virus (HIV) in both children and adults. It works by binding to a receptor on HIV, prohibiting it from entering the cells [1]. Maraviroc is not a stand-alone treatment and must be used in combination with other HIV medications.
How does the use of maraviroc relate to long-COVID?
For patients with long-COVID, treatment options are limited and undefined. Researchers have turned to existing medication therapies in hopes they prove useful. Maraviroc is one option that may be beneficial. In long-COVID, it is theorized that a person is not actively infected but is still shedding the virus in the body. By using maraviroc, the virus will be inhibited from entering the cells, leading to viral death and remission for the patient.
Few studies have determined whether Maraviroc shows benefits. The few that have been completed did show some promise. One study looked at 18 patients prescribed maraviroc and pravastatin, a medication used to lower cholesterol. These patients displayed clinical improvement in symptoms after 12 weeks of treatment. Unfortunately, before this study, these patients used other potential long-COVID treatments, thus confounding whether these results were due to maraviroc, pravastatin, or other therapies [2].
Maraviroc may be a potential option to treat long-term COVID; however, further research needs to be completed to examine its effects on the virus itself. At this time, two additional clinical studies aiming to examine the use of maraviroc in COVID-19 patients have been completed; however, results from these studies are not yet available [3].

Propranolol for long COVID
PROPRANOLOL
What is propranolol?
Propranolol, a medication in the class called beta blockers, is used to treat heart conditions in patients. Beta-blockers work by acting on the beta receptors in the heart, blocking its action and resulting in a decrease in blood pressure.
How can propranolol be used for those with long-COVID?
Recent research has shown that this class of medications may be helpful for those suffering with symptoms of long-COVID. Patients diagnosed with long-COVID often experience symptoms such as lightheadedness, postural orthostatic tachycardia syndrome (POTS), chest pain, and a fast heartbeat. Cardiologists at Cedars-Sinai Hospital have found that treatment with beta-blockers, combined with a low salt intake and adequate hydration, can improve long-COVID symptoms [1].
There is also evidence to suggest that beta blockers have some anti-inflammatory effects. In addition to increasing the heartbeat, beta receptors are pro-inflammatory. They release certain signals that aid in activating the immune response. By blocking these signals, the immune system response decreases, leading to a decrease in clinical symptoms in patients [2]. Additional research is needed to fully understand the scope of propranolol and long-COVID; however, the positive evidence recently discovered provides hope that it may be useful for patients.

IV Hydration for long COVID
IV HYDRATION/VITAMIN THERAPY
What are IV hydration and vitamin therapy?
Many products on the market are labeled IV hydration or vitamin therapy for long COVID and contain various combinations of intravenous vitamins, antioxidants, and amino acids such as vitamin C, vitamin B12, vitamin D, and glutathione. For hydration, they can also contain added electrolytes and fluids. IV infusions are directly absorbed into the bloodstream, whereas oral supplements must be absorbed from the gastrointestinal system before they can reach the bloodstream. Thus, IV infusions can be more effective in supplementation than oral vitamins.
How can IV hydration/vitamin therapy help alleviate certain long COVID symptoms?
An excess release of inflammatory mediators and oxidative stress are believed to be contributing factors in long COVID that lead to a hyperinflammatory state. This oxidative stress and inflammation can lead to the progression of fatigue and neuropsychiatric symptoms, as well as disruptions in blood flow.1 Vitamins such as vitamin C have antioxidant and anti-inflammatory properties that are believed to relieve some of these symptoms. During acute infections, the demand for vitamin C may be high due to an elevated inflammatory response and high metabolic demand; thus, COVID patients can show severe deficiencies in vitamin C. As a result, IV vitamin therapies may help with these deficiencies and reduce inflammation in the body.
What evidence supports the use of IV hydration/vitamin therapy for long COVID?
The use of IV hydration/vitamin therapy for long COVID is controversial. For commercial IV products and IV vitamin clinics marketed online, there have been no studies to demonstrate their effectiveness other than anecdotal patient stories.
The primary intravenous vitamin studied in clinical trials for fatigue is vitamin C. In a systematic review of 9 studies with 720 participants, 3 out of 4 controlled trials showed significantly decreased fatigue after IV vitamin C therapy. All except one of the observational studies also noted a decrease in fatigue scores. Other symptoms that were alleviated include sleep disturbances, difficulty concentrating, depression, and pain. However, these studies mainly focused on fatigue in cancer patients rather than long COVID patients.2
High-dose IV vitamin C has been studied for use in an acute COVID infection with mixed results. One clinical trial of 60 patients randomized to high-dose IV vitamin C or standard COVID antiviral therapy did not find significantly better outcomes in the group treated with IV vitamin C regarding the amount of oxygen saturation at discharge, length of ICU stay, or mortality.3 Another trial of 54 patients with COVID pneumonia randomized to IV vitamin C 2 grams every 6 hours for five days vs. standard treatment found a significant increase in oxygen saturation and a decrease in respiratory rate.4
Overall, there are proposed associations between IV vitamin therapy (specifically vitamin C) and improvement in fatigue. Still, more evidence from clinical trials needs to support its use in long-term COVID patients. In addition, patients with sufficient vitamin levels in their diet should not require additional supplementation.
What should you be aware of when using IV hydration/vitamin therapy?
Given that some IV hydration/vitamin therapies are offered in various settings, such as spas and salons that may not have medical providers administering the infusion, it is important to consult your doctor before considering one. Patients with congestive heart failure or end-stage renal disease must use caution when receiving IV fluids, as it can exacerbate their conditions. These IV therapies are also not regulated by the FDA. They could carry a risk of infection, damage to the injection site, irritation or inflammation of a vein, or air embolism from air entering the IV.5 In addition, these IV therapies can be fairly expensive.

Metformin for long COVID
METFORMIN
What is metformin?
Metformin is a first-line agent used in the treatment of Type II diabetes. It helps lower blood sugar by decreasing the amount of blood sugar made in the liver and decreasing the amount of blood sugar absorbed by the gastrointestinal tract.
How can metformin impact long-COVID?
Although used for diabetes, there has been some research conducted to look at its effects on those with long-COVID. A recent long-COVID study showed that 6.2% of patients using metformin received a long-COVID diagnosis compared to 10.3% of patients not using metformin [1]. This study included pregnant and lactating patients and people between the ages of 30-85. The mechanism by which this occurs is multifold. It is thought metformin possesses anti-inflammatory and antithrombotic effects in addition to its impact on blood sugar. Additionally, it is theorized that metformin can assist in stopping part of the replication process of the COVID-19 virus, thus leading to its death inside the body [2].
Although current guidelines do not support metformin’s use in the treatment of long-COVID, further clinical studies may warrant its use for those suffering from symptoms of long-COVID.
