Calcium channel blockers block the small pores in cells that allow calcium to move in and out and widen blood vessels. It's not clear exactly how the drugs work, but they are used to lower blood pressure, improve irregular heartbeats, and treat migraines. They may also help stabilize moods.
Changes in sleep that last for more than two weeks or interfere with your life can point to an underlying condition. Of course, many things may contribute to sleep problems. Here's what you need to know about the many connections between bipolar disorder and sleep and what you can do to improve your sleep.
Sometimes, a headache can develop after taking certain calcium channel blockers. These headaches should gradually disappear once you have been taking the medication for a while. Talk to your doctor if headaches continue. Some people also report tenderness, swelling, or bleeding of the gums when starting to take calcium channel blockers. Regular brushing, flossing, and gum massages along with routine dental visits can help lessen this effect. As with any medication, it is important to see your doctor regularly to make sure the drug is working properly.
Calcium channel blockers tend to cause fewer serious side effects than some other drugs used to treat bipolar disorder. However, they are not as well studied and may not be effective.
Common calcium channel blocker side effects include:
