Helidac is a prepackaged medication that contains three different antibacterials: bismuth subsalicylate, metronidazole, and tetracycline. These medications work together to treat peptic ulcers caused by Helicobacter pylori (H. pylori) infections. It needs to be taken with an antacid medication (e.g., H~2~ antagonist).
Helidac contains three different medications.
Together, these medications fight H. Pylori (a bacteria that attacks your gut and causes ulcers) by preventing them from growing normally and making proteins needed to survive. Getting rid of the bacteria allows your body to heal the ulcer.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
An antacid medication called an H~2~ antagonist will be prescribed with Helidac because it will lower the acid in your stomach, allowing your stomach ulcer to heal. Make sure to follow your provider's instructions on how and when to take your antacid medication.
Both Helidac and Pylera are used to treat peptic ulcers associated with H. pylori infections. Each medication is packaged differently. Pylera is available as a capsule that combines all three medications into 1 pill for convenience, while Helidac comes co-packaged with 3 separate medications and you'll need to take each medication at the same time. Additionally, Helidac needs to be taken for 14 days, while Pylera needs to be taken for 10 days. Both medications are currently only available as brand medications.
No. Avoid drinking alcohol while you're taking Helidac, and continue to avoid it for three days after you're done with treatment. Drinking alcohol when you're taking metronidazole, an ingredient in Helidac, can lead to a bad reaction, such as nausea, vomiting, fast heartbeat, skin flushing, and sweating.
No, you shouldn't take Helidac with milk or any other dairy product that contains a lot of calcium. You should also avoid taking Helidac with antacids that contain calcium, aluminum, or magnesium. These minerals can prevent tetracycline, an ingredient in Helidac, from being absorbed. Take Helidac at least 1 hour before or 2 hours after having any dairy products. Take Helidac 2 hours before or 6 hours after antacids containing these minerals.
Yes, like other antibiotics, Helidac can interact with certain birth control pills and cause them to not work as well. You might experience breakthrough bleeding or spotting when you're taking Helidac. Use a back-up form of birth control, such as condoms, when you're taking Helidac.
Helidac can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Helidac contains metronidazole, which has been shown to cause cancer in mice and rats. It's unknown whether metronidazole can cause cancer in humans. If you are concerned about this, speak to your healthcare provider.
Helidac can cause harm to unborn babies when taken during pregnancy. Tetracycline, an ingredient in Helidac, might cause permanent tooth discoloration and affect bone development. Additionally, when taken at high doses, tetracycline might raise the risk of serious liver damage in pregnant mothers. There have also been reports of metronidazole, another ingredient in Helidac, causing harm to unborn babies when used during pregnancy. If you're pregnant or planning to become pregnant, talk to your provider about the safest treatment option.
Rarely, the medications in Helidac have caused seizures, swelling of the brain, nerve pain, headache, blurred vision, and brain damage. Some people experience difficulty with walking straight, dizziness, trouble speaking, or uncontrolled body movements. These problems will usually go away within days to weeks of stopping Helidac. Seek medical help if you experience any of these side effects while taking this medication.
Helidac can cause severe skin rashes resulting in serious injury or even hospitalization. Seek medical attention right away if you suddenly develop a fever, burning eyes, skin pain, or red or purple skin rash with blistering and peeling.
Helidac can raise your skin's sensitivity to sunlight and make you more likely to get a sunburn or rash. While taking this medication, make sure to use sunblock and wear protective clothing. Avoid using tanning salons since artificial light can cause similar skin damage. If you develop skin redness or get a rash, stop taking this medication right away and talk to your healthcare provider.
Helidac contains bismuth subsalicylate, which can cause your stool to become black-colored and your tongue to turn dark. These side effects aren't harmful and usually go away on their own a few days after stopping the medication. However, if you get tarry stools or you see blood in your stool, tell your provider right away.
