A recent study showed that about one-third of the people who are taking anticoagulants weren’t aware of the risk for serious interactions when the medication is mixed with over-the-counter drugs. The risks include internal bleeding, which could be dangerous.
According to research, almost all of the people who were on a prescription anticoagulant took some OTC medications or supplements at the same time. Of those, about one-third were taking a product that could cause internal bleeding when taken with the anticoagulant. Patients weren’t aware of the potential interactions or their severity.
What are Anticoagulants?
This type of medication is often used to treat patients who have a higher risk for stroke and are diagnosed with atrial fibrillation. The patients are most often older. The drug most often prescribed is Apixaban. The patients don’t usually have monthly follow-ups or aren’t seen in anticoagulation clinics, so they may not be educated in the possibility of drug interactions.
Medications like Apixaban are used to prevent blood clots for patients with atrial fibrillation. They may also be given after knee or hip replacement surgery to reduce the risk of blood clots. Because it impacts the body’s ability to clot, it can lead to serious bleeding. A person needs medical attention right away if they start noticing changes in vision, confusion, weakness on one side or if their speech becomes slurred. These could be indications of internal bleeding. Other indications include:
- Unusual bruising
- Cuts that bleed longer than normal
- Pain or swelling
- Coughing up blood
- Frequent nosebleeds
- Blood in vomit or stool
- Persistent tiredness
- Difficulty swallowing
The study had researchers interviewing patients from April 2018 to October 2018 who had been taking apixaban. They asked about their knowledge of any possible interactions with the drug and other OTC products. They asked how often they took these other medications which included the following:
- Fish oils
- Herbal teas
- Chinese herbs
The results of the study showed that more education is needed on the risk of bleeding and other dangers to combining anticoagulants and OTC products. The study was limited because of a low response rate, a limited number of products included in the study and the self-reporting of the patients.
Warnings for the Medication
Precautions for the drug list bleeding as a possible side effect. Drinking alcohol daily can increase the risk for stomach bleeding. It also lists other safety measures a person can take, including using a safety razor for shaving and a soft toothbrush. If a person falls and hits their head, they should seek medical care to check for hidden bleeding.
Patients should also tell their doctor if they have a history of stroke, blood disorders, kidney disease or if they suffer from frequent falls.
According to the study, even though these precautions are given, many people are still not aware of the dangers of mixing the medication with other products. Since internal bleeding may not be obvious, it can become a dangerous condition for the patient.
FDA Failed in Monitoring of Program to Curb Opioid Prescriptions
The US Food and Drug Administration (FDA) requested that drug manufacturers of long-acting opioid prescriptions pay for safety training in 2011. However, records show that the agency failed to follow up on whether the program was successful.
The goal of the program was to determine if the training for physicians who prescribed opioids was effective and to monitor other measures being taken to reduce addiction of opioid prescriptions as well as overdoses and fatalities.
A Flawed Program
According to critics, the program had a flawed design from the beginning, but it was never evaluated accurately either. Congress granted authority to the FDA back in 2007 to require training of physicians on drugs that were likely to cause addiction. The bill went into effect as a response to the oversight of the agency to monitor dangerous drugs.
Documents showed that the FDA couldn’t determine if the program was effective because the design of the studies was poor. Around 60 drugs can be included in the risk-management program. This not only includes opioids but other medications, such as isotretinoin, which is a drug to treat acne and often branded as Accutane.
Critics of the program say that the FDA allowed the pharmaceutical companies to monitor their own training. It also fails to monitor the quality of the training being given. According to a report from the Department of Health and Human Services, only about 14 percent of the programs for safety that had been reviewed by the FDA were able to meet the requirements.
The Dangers of Prescription Drugs
When it came to opioids, the requirement was that 60 percent of prescribers must take the classes, but only less than 30 percent followed through during 2012 to 2016. Even though the number of prescriptions given out was dropping, it couldn’t be determined if it was because of the training. Another issue with the program is that it didn’t provide accurate data on the correlation between the training and the reduction in overdoses and deaths. National data on overdoses had no distinction to show which doctors had taken the training and which ones hadn’t. Because of this, it was impossible to determine if the program was effective in this area.
This same problem has occurred in other programs. For instance, one program was designed to monitor the prescribing of fentanyl drugs that are to be given only to patients with cancer. While these drugs were meant only for those specific patients, many doctors prescribed the medication for other conditions.
The FDA made it a requirement for safety programs to be in place when prescribing all opioid prescriptions and not just the long-acting kinds. This change happened in 2017, but it implies that the long-acting opioids are safe for chronic pain, which goes against most research.
Prescription painkillers have been responsible for many deaths related to overdose. Doctors were prescribing these drugs at a high rate that reached its peak in 2012 at 81.3 prescriptions per 100 patients. While the rate has declined, overdosing is still a major problem in the US, especially in certain regions.
House Approves Bill Which Could Reduce Prescription Drug Prices
The House recently approved a bill that is aimed at lowering the cost of prescription medications by allowing the government to negotiate with manufacturers of the drugs.
Bill H.R. 3
The bill is titled H.R. 3 and would have a direct impact on Medicare programs. The provisions include benefits for vision, dental and hearing, and it also caps the costs Medicare beneficiaries pay out of pocket to $2000.
This bill was proposed and supported by Democrats, but the Republicans have also been working on legislation to cut prescription costs. Pharmaceutical companies oppose both this bill and the Senate bill.
One of the features of the bill includes allowing the Department of Health and Human Services to negotiate pricing for as many as 250 of the most common drugs. Manufacturers would have to provide the same prices to insurers as what was agreed upon during negotiations.
Drug manufacturers would be required to pay rebates to Medicare if prices went up faster than inflation. The Senate bill, which is sponsored and supported by Republicans, doesn’t contain the same provisions, but it does require the companies to pay rebates for raising prices above the rate of inflation.
Other Options for Legislation
Even though the Republicans didn’t agree with the Democrats’ bill, they did come up with a similar measure, which had the support of eight Democrats at the vote. It would not only cap the expenses paid out of pocket, but it would require insurance providers to provide information about medication prices to patients before they were prescribed the drugs.
The argument against the legislation to allow government to negotiate prices is that it would reduce the amount of money for research and development with pharmaceutical companies, which could limit the number of new medicines available for life-threatening illnesses. It has been estimated that the enactment of the bill would reduce the number of new drugs available by 40 for the next 20 years.
H.R. 3 allocates over $10 billion for the National Institutes of Health, which would be used for research to provide breakthrough cures. Taxpayers could save as much as $5 billion during the next ten years if it is enacted.
The rising costs of prescription medications has placed a hardship on many Americans. Some even have difficulty affording food and other necessities because of the expensive drugs they need. The situation has put pressure on lawmakers to find a solution.
Prescription manufacturers do not support the measures that limit their ability to raise prices. However, politicians recognize the need to make drugs more affordable for the average American. With another election year coming up, they are working on their campaign promises to ensure support from their constituents for the next election.
While it’s not expected for the bill to become law in its present state, there is hope that the overall goal will be met even with the changes that would be made. Some day in the future, Americans may be able to afford the drugs they need to manage their medical conditions or cure them.
FDA Tests Diabetes Drug for Carcinogen Levels
The US Food and Drug Administration is testing for the presence of certain cancer-causing chemicals in the diabetes medication metformin. This medication is a prescription drug that is given to patients with type 2 diabetes to control high blood sugar.
Continued Risks with NDMA in Drugs
Several drugs have been discovered to contain known carcinogens at levels not acceptable to the FDA in the past year. Now, metformin is under scrutiny due to the possibility that it may also contain a carcinogenic substance. The concern with these chemicals is that continued exposure could raise the risk for developing cancer in the future.
Other countries have found some metformin drugs to have low levels of N-nitrosodimethylamine or NDMA. After testing those medications, it has been determined that the level of NDMA is in the acceptable range, which is what is naturally found in food and water. However, some countries are recalling metformin medications. The US is not on that list at this time.
The FDA has a current investigation into the medication to determine if NDMA is found and whether it is above the acceptable limit of 96 nanograms per day. The agency is working with manufacturers to test the samples of the drug. If levels above 96 nanograms are found, the FDA will recommend recalls.
Experts recommend that patients continue taking the medication. If a recall is issued, the FDA will provide information to health care personnel and patients. It can be dangerous to stop taking this medication without the advice of their physician. There are no alternative medications to treat the high blood sugar in the same way.
What Does Metformin Do?
This medication works in several ways to control blood sugar in diabetics. It reduces the amount of sugar the liver makes as well as how much is absorbed throughout the body from the person’s diet. It also causes the insulin receptors in the body to be more accurate in how much insulin the system manufactures.
One of the benefits of this medication is that it doesn’t increase the amount of insulin being made in the body, which means the patient has a lower risk of hypoglycemia or low blood sugar. Other medications carry a higher risk for this condition.
The doctor may prescribe metformin in tablet form, a liquid or one of two long-acting medications. Brand names for metformin include Glucophage XR, Glumetza, Fortamet and Riomet. The medication was originally manufactured by Bristol-Myers Squibb, but several manufacturers make the generic version.
Taking a medication like metformin can control sugar levels and prevent many health issues that are related to high blood sugar. This includes diabetic neuropathy, heart disease and diabetic retinopathy. Regular use of the medication may prevent complications which arise from diabetes.
Manufacturers of metformin are working with the FDA to determine if metformin is safe for use. Anyone who is concerned about the risk of carcinogenic chemicals in this medication or other medicines should discuss the issue with their health care provider. The doctor can recommend other options or put their minds at ease.
