Magnesium citrate |
Only Magnesium Citrate is problematic..
Mg citrate should be only used in recommended doses. It is a highly absorbable form of magnesium used as a saline laxative for occasional constipation, working by drawing water into the intestines to soften stool, and as a dietary supplement for muscle relaxation, nerve function, heart health, and energy production, available in liquids, powders, and capsules, often with a tart taste. It's important to follow label directions, and stay hydrated, and not use it long-term without a doctor's advice. Don't fly after this medication. The others are OK.
Disclaimer: Neither the FAA nor FlightPhysical.com will attempt to publish all-inclusive references. Online guidance does not replace medical advice from your PCP and/or AME. Most doctors are not AMEs, and your regular Primary Care Provider (PCP) or specialist will know more about you and/or your specific medical condition than an AME, but is probably untrained or unfamiliar with aviation medicine. Follow 14 CFR 61.53 (duty to self-ground when ill) for your safety and that of your passengers. Don't fly after taking a new medication for the first time until 48 hours have past without side effects.
When in doubt - DO NOT FLY.
