Ranitidine is a medication that belongs to a group of drugs called histamine-2 blockers. It is used to treat and prevent ulcers in the stomach and intestines, as well as conditions where the stomach produces too much acid, such as gastroesophageal reflux disease (GERD). While ranitidine can be effective in managing these conditions, it has been associated with certain side effects, including sleep disturbances. The medication can cause adverse reactions, such as bizarre dreams and gastrointestinal symptoms, leading to disrupted sleep. Additionally, ranitidine has been found to contain a possible cancer-causing impurity, leading to its withdrawal from the market in the United States. Therefore, it is crucial to consult a healthcare professional before taking ranitidine or combining it with other medications, including sleep aids, to ensure safe and effective use.

What You'll Learn
Ranitidine may cause sleep disturbances
Ranitidine is a medication that belongs to a group of drugs called histamine-2 blockers or H2 blockers. It works by reducing the amount of acid in the stomach and is typically used to treat gastrointestinal conditions such as peptic ulcers, gastroesophageal reflux disease (GERD), and stomach and intestinal ulcers. It is also used to prevent stress ulcers, stomach damage from non-steroidal anti-inflammatory drugs (NSAIDs), and aspiration of stomach acid during anaesthesia.
While ranitidine can be effective in treating these conditions, it is important to note that it may cause sleep disturbances in some individuals. In a case report published in PMC, a 40-year-old man with a history of a wart on his right plantar foot developed sleep disturbances with bizarre dreams and gastrointestinal symptoms after initiating therapy with ranitidine. The sleep disturbances resolved after discontinuing the medication and recurred when he restarted it, confirming the diagnosis of ranitidine-associated sleep disturbance.
The Naranjo scale, which is used to determine the probability of an adverse drug reaction, indicated a score of eight in this patient, suggesting a probable adverse reaction to ranitidine. While sleep disturbance caused by ranitidine is uncommon, similar reactions have been observed with other H2 antihistamines such as cimetidine and famotidine. Therefore, clinicians should be aware that sleep disturbance is a potential side effect of this medication.
It is important for patients taking ranitidine to be vigilant about any side effects, including sleep disturbances. If you experience trouble sleeping, bizarre dreams, or other adverse effects while taking ranitidine, consult your doctor immediately. They may advise you to discontinue the medication and explore alternative treatment options that do not carry the same risks.
Additionally, it is worth noting that ranitidine has been withdrawn from the market in the United States due to safety concerns. The U.S. Food and Drug Administration (FDA) has discovered a possible cancer-causing impurity, N-nitrosodimethylamine (NDMA), in some ranitidine products. As a result, patients taking prescription ranitidine should consult their healthcare professionals about alternative treatments that do not carry the same risks associated with NDMA.

Ranitidine has been withdrawn from the US market
Ranitidine, commonly known by the brand name Zantac, belongs to a group of drugs called histamine-2 blockers. It works by reducing the amount of acid the stomach produces and is used to treat and prevent ulcers in the stomach and intestines. It is also used to treat conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome. Ranitidine was also used to treat gastroesophageal reflux disease (GERD) and other conditions in which acid backs up from the stomach into the oesophagus, causing heartburn.
Ranitidine was withdrawn from the US market in April 2020. The drug was found to contain N-Nitrosodimethylamine (NDMA), a cancer-causing chemical. NDMA is a probable human carcinogen, meaning it is a potent carcinogen in animals, but there is not enough evidence to verify its carcinogenic effect on humans. The FDA confirmed that the NDMA impurity in some ranitidine products increases over time and when stored at higher than room temperatures, which may result in unacceptable levels of consumer exposure to NDMA.
The FDA has stated that its decision to withdraw ranitidine from the market is in line with its commitment to ensuring that the medicines Americans take are safe and effective. The agency has advised consumers taking over-the-counter ranitidine to stop taking any tablets or liquids they currently have, dispose of them properly, and not buy more. Patients taking prescription ranitidine should speak with their healthcare professional about other treatment options.
Ranitidine may cause side effects such as dizziness, sleepiness, tiredness, or weakness. It can also cause trouble sleeping and irritation where the drug is given. It is important to note that this is not a complete list of side effects, and patients should call their doctor for medical advice if they have any questions or concerns. Patients should also inform their doctor and pharmacist about all the drugs they are taking, including prescription and over-the-counter medications, natural products, and vitamins.

Ranitidine can cause allergic reactions
It is unsafe to take ranitidine with a sleep aid without first consulting your doctor. Ranitidine is a commonly used, over-the-counter medication that is usually well-tolerated and has mild side effects. However, it can cause allergic reactions in some people.
Ranitidine is a competitive reversible H2 receptor antagonist, commonly used to treat peptic ulcers, gastroesophageal reflux disease, and Zollinger-Ellison syndrome. It is also used to prevent stress ulcers and stomach damage from nonsteroidal anti-inflammatory drugs (NSAIDs). While it is typically considered a safe medication, there have been rare cases of severe allergic reactions, including anaphylaxis, reported with its use.
Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur even in individuals without a prior history of allergies. It is characterized by rapid-onset respiratory and cardiovascular symptoms, such as chest tightness, difficulty breathing, hives, swelling of the face and throat, and a diffuse rash. In some cases, anaphylaxis can lead to fatal outcomes if not treated promptly.
If you experience any signs or symptoms of an allergic reaction after taking ranitidine, seek emergency medical help immediately. Do not wait for the symptoms to worsen, as anaphylaxis can progress rapidly. Stop taking ranitidine and contact your doctor right away if you experience any adverse reactions.
Additionally, it is important to inform your doctor and pharmacist about all the medications you are currently taking, including prescription drugs, over-the-counter medications, vitamins, and herbal supplements. This information will help them assess the safety of your treatment plan and identify any potential drug interactions.

Ranitidine may affect certain lab tests
Ranitidine is a drug that belongs to a group of drugs called histamine-2 blockers. It works by reducing the amount of acid in the stomach and is used to treat and prevent ulcers in the stomach and intestines. It is also used to treat conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome and gastroesophageal reflux disease (GERD).
Ranitidine was withdrawn from the US market in April 2020 due to safety concerns. The FDA found a possible cancer-causing impurity in some ranitidine products, known as N-nitrosodimethylamine (NDMA). NDMA is a probable human carcinogen, and the impurity increases over time and when stored at higher temperatures, which may result in unacceptable levels of exposure.
The medication may prevent other drugs taken by mouth from being absorbed properly. This is because ranitidine decreases stomach acid, and some drugs require stomach acid for proper absorption. Drugs that may be affected include atazanavir, dasatinib, certain azole antifungals (such as itraconazole and ketoconazole), levoketoconazole, pazopanib, and sparsentan, among others. It is important to discuss any potential drug interactions with your doctor or pharmacist to ensure the safe and effective use of your medications.
