Drugs that increase heart rate, such as beta-blockers, calcium channel blockers, and digoxin can reduce the ability of magnesium threonate to lower heart rate. If your physician has determined that you need these drugs to treat your condition, then you may be at risk for magnesium threonate interactions. However, it’s important to note that not all patients will react the same way to these drugs. Your physician will likely test your blood levels of magnesium threonate before beginning treatment, and may recommend adjusting your dosage if necessary. Keep reading to learn about these drug interactions and how to avoid them if they arise during treatment with magnesium threonate.
Beta-Blockers
The most common interaction between magnesium threonate and beta-blockers occurs when your physician is using beta-blockers to treat angina. In this situation, magnesium threonate can cause your blood pressure to drop too low, which can trigger angina. To avoid this interaction, your physician may recommend that you use a beta-blocker that does not cause blood pressure to drop as much. Alternatively, he or she may recommend that you take a beta-agonist instead, which causes your blood pressure to rise.
Digoxin
If your physician has determined that you need a digoxin to treat your condition, then you may be at risk for a magnesium threonate interaction. This is because digoxin can interfere with the way your body absorbs magnesium threonate. If you need both drugs, your physician may recommend that you take them at different times of the day. Alternatively, he or she may recommend that you switch to another form of magnesium that is not absorbed as quickly.
Calcium Channel Blockers
Calcium channel blockers are a type of medication that can be used to treat high blood pressure, angina, and irregular heartbeats. If you are taking a calcium channel blocker to treat one of these conditions, then you may be at risk for a magnesium threonate interaction. This is because calcium channel blockers can reduce your body’s ability to absorb magnesium threonate. To avoid this interaction, you may need to take your calcium channel blocker at a different time than your magnesium threonate.
Other Considerations
If you are taking any other medications, you should let your physician know about them before starting treatment with magnesium threonate. Your physician may be able to change your dosage of one or both drugs, or recommend another form of magnesium threonate that is not affected as much by these drugs.
