Bismuth Subcitrate is used to treat stomach ulcers, including those caused by H. pylori, and to protect the stomach lining from damage by acid.
Bismuth Subcitrate works by forming a protective layer over the ulcer, shielding it from stomach acid, and helping it heal.
Common side effects include darkened stools, constipation, and mild stomach upset. Serious side effects are rare but may include allergic reactions.
It should only be used as prescribed. Long-term use can cause side effects such as darkened stools or other gastrointestinal issues.
Bismuth Subcitrate can interact with other medications, especially those used to treat infections, so it is important to inform your doctor of all medications you're taking.
Bismuth Subcitrate is not specifically used for acid reflux, but it may help with ulcers caused by acid damage to the stomach lining.
Bismuth Subcitrate is usually taken in tablet or liquid form with meals and at bedtime. Follow your healthcare provider's instructions.
Consult your doctor before using Bismuth Subcitrate during pregnancy, as it may not be recommended for all cases.
If you miss a dose, take it as soon as you remember unless it's almost time for your next dose. Do not take two doses at once.
Bismuth Subcitrate is part of a combination therapy for H. pylori infections, helping to kill the bacteria and reduce stomach inflammation.
