Zinc treatment reduces nausea risk
We conducted a study to evaluate how effective NPC-25, a new form of zinc, is compared to a well-known treatment, NOBELZIN™, for patients with low zinc levels. Participants in this trial had their zinc levels checked and were grouped to receive either NPC-25 or NOBELZIN™.
For a period of up to 24 weeks, we aimed to maintain their zinc levels within a specific target range while closely monitoring for side effects. One of our main goals was to see if NPC-25 could maintain these target zinc levels similarly to NOBELZIN™.
Our findings revealed that NPC-25 was indeed non-inferior to NOBELZIN™, meaning it worked just as well. Importantly, we also observed that those taking NPC-25 reported fewer digestive issues, like nausea and vomiting. This suggests that while both treatments were effective, NPC-25 might be the gentler option.

We explored the impact of zinc acetate dihydrate on several symptoms, including nausea, through a comprehensive study that assessed its safety and effectiveness for treating hypozincemia over a 52-week period. From the data collected, we observed an overall adverse reaction rate of 9.4%, with nausea reported in 1.4% of patients.
Despite nausea being a concern, the benefit of zinc acetate dihydrate for other indications was notable, with an efficacy rate of 83%. For patients experiencing symptoms such as pressure ulcers or stomatitis, the effectiveness was strikingly high. However, the specific effect of zinc on nausea is not definitively isolated within the study results, making it hard to gauge its direct and unique benefits.
In essence, while zinc acetate dihydrate shows promise for a variety of symptoms, including nausea, the evidence does not conclusively highlight its effectiveness for this particular issue on its own. Overall, it appears that zinc treatment can contribute positively to addressing several related health problems.

Zinc affects post-op nausea minimally
We explored the effectiveness of zinc-impregnated pharyngeal packs in reducing post-operative nausea and sore throat among patients undergoing septorhinoplasty. In this study, we divided 220 patients into four groups, each receiving different types of pharyngeal packs: normal saline-impregnated vibril, normal saline-impregnated gauze, zinc solution-impregnated vibril, and zinc solution-impregnated gauze.
Our findings revealed that there was no significant difference between the groups regarding the occurrence of sore throat shortly after surgery and at various intervals thereafter. However, we did observe that those using zinc solution-impregnated gauze experienced significantly less severity of nausea two hours post-surgery compared to those using normal saline-impregnated gauze. Ultimately, while zinc did not help with sore throat, it showed promise in alleviating nausea.

We examined the effects of pyridoxine, or vitamin B6, in reducing postoperative nausea and vomiting (PONV) for patients undergoing elective gynecological laparoscopic surgery. In this study, patients aged 18 to 65 were randomly assigned to receive either pyridoxine or a placebo (normal saline) before anesthesia.
All patients also received a regimen that included dexamethasone and ondansetron, two well-known anti-nausea medications. Reports from the patients indicated that those who received pyridoxine experienced a reduced incidence of nausea and vomiting following their surgery compared to those who received the placebo.
While our findings are promising, it is important to note that pyridoxine was used in conjunction with other medications, making it difficult to ascertain its effect in isolation. Future multicenter studies will help us confirm the effectiveness of pyridoxine in more diverse settings and populations.

Zinc's tolerability in diarrhoea treatment
We aimed to understand how zinc tablets, often recommended for treating diarrhoea in young children, affect nausea and overall treatment adherence. In this open-label study, we involved children aged 3 to 59 months who visited the outpatient department at Dhaka Hospital.
Our findings revealed that a significant number of children, about 92.7%, tolerated the modified zinc tablets well. However, we also noted that 32.8% of the children experienced vomiting, and 19.5% had regurgitation, while a smaller number, 7.4%, reported nausea. Interestingly, despite these side effects, a remarkable 99.3% of caregivers expressed their willingness to continue using this zinc formulation in the future.
Overall, while our study demonstrated that the modified zinc formulation was generally well-tolerated, we cannot overlook the considerable instances of nausea and vomiting experienced by the children. Balancing these side effects with the willingness of caregivers offers a complex view of zinc's role in diarrhoea management.

Nausea signal
These vitamins are not for daily use, as the manufacturer recommends stopping after six days. I take them when a cold is coming, but they can make me feel terribly sick for 2-4 hours. The taste of the chewable tablets is decent.

This zinc has an excellent composition. We take it as soon as the illness is felt, one tablet per day for 5-7 days, and it works quickly. It’s large but tasty; even my child enjoys it. It’s best not taken on an empty stomach as it can cause nausea.

I liked these vitamins; the cherry flavour was slightly sour. I took one tablet every two hours when I felt unwell, but it’s best not to take it on an empty stomach as it can cause nausea. Overall, I liked the product and recovered in a few days, especially with the additional vitamins I was taking alongside zinc.
