During this course, most Prevacid side effects are manageable, should they occur. However, dangerous side effects such as seizures, fainting or severe pain should be reported to a healthcare provider immediately. Prevacid and other lansoprazole medications should never be taken continuously or over a longer period of time than recommended on the packaging without the supervision and advice of a doctor.

Prevacid and Broken Bones

The FDA warns that PPI antacids such as lansoprazole or Prevacid may put patients at a higher risk of bone fractures. The risk of these side effects increase in patients who have taken the medication for more than a year or who use it at high doses. Patients over the age of 50 are more likely to experience these bone fractures than younger patients. The most likely fractures associated with this side effect are those of the wrist, spine and hip.

Prevacid is extremely effective at treating painful conditions associated with excess stomach acid. However, many patients choose to use this medication as a treatment for regular heartburn and consequently put themselves at a higher risk of dangerous side effects. If you decide to take Prevacid over-the-counter without a doctor’s prescription, you should follow the 14-day dosing schedule exactly. You should never take these 14-day Prevacid courses more than three times in a single year.
