H2 Blockers- How Long do They Take to Work?
H2 blockers, such as ranitidine (Zantac) and famotidine (Pepcid AC), are medications used to decrease the production of stomach acid. They are commonly used to treat conditions such as ulcers, gastroesophageal reflux disease (GERD), and excess acid production. The time it takes for H2 blockers to start working can vary depending on the individual and the specific condition being treated. However, in general, these medications start providing relief within 1-2 hours after taking them.
It's important to note that H2 blockers are not meant for immediate relief of heartburn or acid reflux symptoms. They are typically taken regularly over a period of time to reduce the occurrence and severity of symptoms.
