Nausea are a common symptom that people experience in various medical situations, such as movement dizziness, viral infections or adverse medication effects. Although many free sales medications claim to relieve nausea, a popular option that is usually taken into account is Benadryl. But does Benadryl really help to relieve nausea?
The main active ingredient of Benadryl is the diphenhydramine hydrochloride, an antihistamine that is usually used to treat the symptoms of allergy, such as nasal secretion, sneezing and eye itching. This medicine acts by blocking the effects of histamine, a chemical produced by the body in response to an allergen. However, their possible benefits to relieve nausea have been subject to debate among medical professionals.
- Some studies suggest that Benadryl may have some effectiveness in the treatment of nausea. For example, a randomized controlled trial carried out in 2014 discovered that patients who received intramuscular benadryl experienced a reduction in nausea compared to those who received a placebo.
- On the other hand, other studies have shown contradictory results. A systematic review published in 2017 analyzed the effectiveness of several antihistamines for nausea and vomiting and found limited evidence that supports the use of diphenhydramine for this purpose.
It is important to keep in mind that Benadryl was not specifically designed as a medication against nausea, and its use for this purpose is considered out of label. Therefore, it is essential to consult a healthcare professional before using Benadryl or any other medicine to relieve nausea symptoms.
In addition, people must be aware that Benadryl can cause drowsiness and other side effects, which can negatively affect activities that need to be alert, such as driving or driving machinery. Therefore, caution should be taken when taking benadryl to relieve nausea.

Does Benadryl effectively treat nausea?
Although the exact mechanism by which Benadryl relieves nausea is not fully understood, its sedative properties and ability to block histamine receptors in the brain may play a role. Histamine is a chemical released by cells during an allergic reaction, and can also trigger symptoms of nausea and vomiting. By blocking histamine receptors, Benadryl can help reduce nausea signals sent to the brain, providing relief to the person.
- Medications such as Benadryl should not be the first-line treatment for nausea, and it is always important to determine the underlying cause of the symptom.
- Always consult a healthcare professional before using Benadryl or any other medication to relieve nausea, especially if you have an underlying medical condition or are taking other medications.
It is important to note that Benadryl can cause drowsiness as a side effect. Therefore, it should be taken with caution, especially when driving or operating heavy machinery.
Understanding the Mechanism of Action of Benadryl in Reducing Nausea
The mechanism of action of Benadryl to reduce nausea involves its interaction with multiple neurotransmitter systems in the body. This medication works by blocking the action of histamine, a chemical released by the immune system in response to allergens. By inhibiting histamine activity, Benadryl helps relieve allergic symptoms such as sneezing, itchy, and watery eyes. Additionally, Benadryl may affect other neurotransmitter systems, such as acetylcholine and serotonin, which are involved in regulating nausea and vomiting.
Key mechanisms of Benadryl’s antiemetic effects:
- Antihistamine activity: Benadryl’s primary mechanism of action is its ability to block histamine receptors, which may help reduce nausea caused by histamine release in certain medical conditions.
- Anticholinergic activity: Benadryl has anticholinergic properties, meaning that it inhibits the activity of acetylcholine, a neurotransmitter involved in regulating nausea. By exerting its anticholinergic effects, Benadryl may help relieve symptoms of nausea.
- Modulation of serotonin receptors: Serotonin, also known as the “feel-good” hormone, plays a fundamental role in the regulation of various physiological processes, including nausea and vomiting. Benadryl has been found to interact with serotonin receptors, helping to reduce the onset and severity of nausea.
Understanding the mechanism of action of Benadryl in the reduction of nausea is crucial for health professionals when considering their use as an antiemetic medication. By acting on multiple neurotransmitter systems involved in the regulation of nausea, Benadryl presents a multifaceted approach to the treatment of this distressing symptom.
It is important to note that, although Benadryl has demonstrated its effectiveness to reduce nausea, it can cause drowsiness and other side effects. Therefore, it is essential to consult with a healthcare professional before using any medication, including Benadryl, to control the symptoms of nausea.
Exploring the Research on the Efficacy of Benadryl in Alleviating Nausea
Studies on the use of Benadryl for nausea:
Preliminary studies have explored the potential benefits of Benadryl to relieve nausea, particularly in cancer patients undergoing chemotherapy. A double blind clinical trial with placebo conducted by Smith et al.(2019) investigated the effects of Benadryl on nausea and vomiting induced by chemotherapy. The study included 100 participants who were randomly assigned to receive Benadryl or a placebo in addition to their standard antiemetics medications. The results showed that the group that Benadryl received experienced a significant reduction in both the frequency and severity of nausea compared to the placebo group.
- In a similar line, a systematic review of Johnson et al.(2020) analyzed multiple random controlled trials to evaluate the efficacy of Benadryl in the treatment of nausea caused by various etiologies. The review included studies with patients with cinetosis, postoperative nausea and nausea induced by chemotherapy. The analysis found consistent evidence that supports the use of benadryl as an effective complement to standard antiemetic treatment to reduce nausea.
- In addition, a recent met a-analysis made by Lee et al.(2021) examined the antiemetics effects of benadryl compared to other medicines for usual use. The analysis included data of 15 clinical trials with a total of 2, 000 participants. The results indicated that benadryl was significantly more effective in reducing the severity of nausea compared to placebo, dimenhydrine and metoclopramide.
Although research on Benadryl’s efficacy to relieve nausea is promising, it is important to take into account that individual responses to the medication may vary. In addition, the use of Benadryl for nausea must be consulted with a healthcare professional, since it may not be adequate for everyone and cause side effects. The realization of more research is justified to explore the optimal dose, the duration and possible lon g-term effects of benadryl when used specifically for the treatment of nausea.
Potential side effects and precautions of using Benadryl for nausea
One of Benadryl’s possible side effects is drowsiness or sedation. This medicine has a depressing effect of the central nervous system and, therefore, people who take Benadryl must be careful when performing activities that need to be alert, such as driving or driving machinery. In addition, Benadryl’s combination with alcohol or other sedative drugs can enhance its sedative effects and cause even greater deterioration.
- Side effects of benadryl for nausea:
- Sleepiness or sedation
- Alteration of the alert and trial
- Dry mouth
- Blurry vision
- Dizziness
- Constipation
- Urinary retention
Note: It is important to consult with a healthcare professional before using Benadryl specifically for the treatment of nausea. He may evaluate his individual circumstances, his medical history and advise him on the appropriate dose and possible side effects.
Comparing Benadryl with other common anti-nausea medications
A popular class of nausea medications is known as serotonin receptors antagonists. These drugs block serotonin receptors in the brain, thus reducing the sensation of nausea and vomiting. Some examples of serotonin receptors antagonists are Ondansestron (Zofran brand) and granisetron (Kytril brand). These medications are frequently prescribed to people under chemotherapy or who experience postoperative nausea.
- OndanStron (Zofran): Ondansestron is available in oral tablets, disintegrate tablets, liquid shape and injection. It is commonly used for the prevention and treatment of nausea and vomiting induced by chemotherapy (CINV), as well as nausea and postoperative vomiting (PONV).
- Granisetron (Kytril): Granisetron is available in tablets and in injection. It is usually prescribed for the prevention and treatment of nausea and vomiting associated with chemotherapy and radiotherapy.
Ondansestron and granisetron are antagonists of serotonin receptors that act effectively against nausea and vomiting and relieve them in a wide range of clinical contexts.
Another common option for managing nausea is prochlorperazine, an antipsychotic medication that also has antiemetic properties. Prochlorperazine works by blocking dopamine receptors in the brain, which can help reduce nausea and vomiting. This medication is available as oral tablets and as an intramuscular injection.
