HHP Medication Safety Watch: February 2021
This list contains selected items from the full FDA list of recalls, withdrawals, and alerts for medicines and certain health products. We've provided links to FDA information for each product and its maker. Unless otherwise noted, these actions apply only to the specific brand name of the product listed. Talk to your healthcare provider before stopping or changing any medicines or treatments that they have recommended for you.
Dietary supplements may contain undeclared medicines
- Adam's Secret Extra Strength 1500 and Adam's Secret Extra Strength 3000 capsules (maker: Adamssecret.co)
Comment: These products are marketed as nutritional supplements to improve male sexual function. The FDA has found that they may contain sildenafil and/or tadalafil, prescription medicines that treat erectile dysfunction (ED). Sildenafil and tadalafil may cause a dangerous fall in blood pressure, especially if taken with nitrate drugs; other possible side effects include headache, flushing, or stomach upset.
Packaging error may lead to incorrect dosing of blood thinner
- Enoxaparin Sodium Injection (maker: Apotex Corp.)
Comment: Enoxaparin is a medicine that is injected under the skin to prevent blood clots in the legs and for certain heart problems. Some batches of this medicine have been recalled because they were packaged with syringes with incorrect markings. This could lead to taking a dosage that is too high (which could cause bleeding) or too low (which could lead to blood clots, heart attack, or other complications).
Oxygen measurement devices may produce incorrect readings
Comment: The FDA has issued a safety communication to highlight possible inaccuracies of pulse oximeters, especially for people of color. These devices clip on to the tip of the finger to estimate oxygen levels. Recent research shows that pulse oximeters may overestimate oxygen levels in as many as 11% to 17% of people of color, but in only about 4% to 6% of white people. These inaccuracies could lead to undertreatment, such as less oxygen therapy than needed; less frequent patient evaluation and monitoring; and underestimating the severity of illness.
Pulse oximeters have been recommended for home use to monitor lung function, a trend accelerated by the pandemic. The FDA recommends increased awareness of this potential problem and avoiding overreliance on pulse oximeter readings, especially for people of color.
