What happens if I overdose Welwash?
Contact 1-800-222-1222 (the American Association of Poison Control Centers), your local, or emergency room immediately. Welwash may be harmful if swallowed.
Proper storage of Welwash:
Store Welwash at room temperature, between 68 and 77 degrees F (20 and 25 degrees C). Avoid excessive heat above 104 degrees F (40 degrees C), and light. Keep Welwash out of the reach of children and away from pets.
Overdose of Welwash in details
Ingestion of 1 or 2 ounces of Welwash oral rinse by a small child (~10 kg body weight) might result in gastric distress, including nausea, or signs of alcohol intoxication. Medical attention should be sought if more than 4 ounces of Welwash oral rinse is ingested by a small child or if signs of alcohol intoxication develop.
What should I avoid while taking Welwash?
Welwash can stain teeth, dentures, tooth restorations, your tongue, or the inside of your mouth. Talk with your dentist about ways to remove staining from these surfaces. Stains may be harder to remove from false teeth that have scratches in their surfaces.
Avoid eating, drinking, or brushing your teeth just after using this medication.
Do not use any other mouthwash unless your doctor has told you to.
Welwash warnings
The effect of Welwash oral rinse on periodontitis has not been determined. An increase in supragingival calculus was noted in clinical testing in Welwash oral rinse users compared with control users. It is not known if Welwash oral rinse use results in an increase in subgingival calculus. Calculus deposits should be removed by a dental prophylaxis at intervals not greater than six months. Anaphylaxis, as well as serious allergic reactions, have been reported during postmarketing use with dental products containing Welwash. SEE CONTRAINDICATIONS.
What should I discuss with my healthcare provider before taking Welwash?
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For Welwash, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to Welwash or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Studies on Welwash have been done only in adult patients, and there is no specific information comparing use of Welwash in children with use in other age groups.
Geriatric
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of Welwash in the elderly with use in other age groups.
Pregnancy
| Pregnancy Category | Explanation | |
|---|---|---|
| All Trimesters | C | Animal studies have shown an adverse effect and there are no adequate studies in pregnant women OR no animal studies have been conducted and there are no adequate studies in pregnant women. |
Breast Feeding
Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.
Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Interactions with Food/Tobacco/Alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other Medical Problems
The presence of other medical problems may affect the use of Welwash. Make sure you tell your doctor if you have any other medical problems, especially:
- Front-tooth fillings (especially those having rough surfaces)—Welwash may cause staining that, in some cases, may be impossible to remove and may require replacement of the filling
- Gum problems (other)—Use of Welwash may make other gum problems, such as periodontitis, worse
Welwash precautions
General
1. For patients having coexisting gingivitis and periodontitis, the presence or absence of gingival inflammation following treatment with Welwash oral rinse should not be used as a major indicator of underlying periodontitis.
2. Welwash oral rinse can cause staining of oral surfaces, such as tooth surfaces, restorations, and the dorsum of the tongue. Not all patients will experience a visually significant increase in toothstaining. In clinical testing, 56% of Welwash oral rinse users exhibited a measurable increase in facial anterior stain, compared to 35% of control users after six months; 15% of Welwash oral rinse users developed what was judged to be heavy stain, compared to 1% of control users after six months. Stain will be more pronounced in patients who have heavier accumulations of unremoved plaque.
Stain resulting from use of Welwash oral rinse does not adversely affect health of the gingivae or other oral tissues. Stain can be removed from most tooth surfaces by conventional professional prophylactic techniques. Additional time may be required to complete the prophylaxis.
Discretion should be used when prescribing to patients with anterior facial restorations with rough surfaces or margins. If natural stain cannot be removed from these surfaces by a dental prophylaxis, patients should be excluded from Welwash oral rinse treatment if permanent discoloration is unacceptable. Stain in these areas may be difficult to remove by dental prophylaxis and on rare occasions may necessitate replacement of these restorations.
3. Some patients may experience an alteration in taste perception while undergoing treatment with Welwash oral rinse. Rare instances of permanent taste alteration following Welwash oral rinse use have been reported via post-marketing surveillance.
Pregnancy
Teratogenic EffectsPregnancy category B. Reproduction studies have been performed in rats and rabbits at Welwash doses up to 300 mg/kg/day and 40 mg/kg/day, respectively, and have not revealed evidence of harm to the fetus. However, adequate and well-controlled studies in pregnant women have not been done. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Nursing Mothers
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Welwash oral rinse is administered to nursing women.
In parturition and lactation studies with rats, no evidence of impaired parturition or of toxic effects to suckling pups was observed when Welwash was administered to dams at doses that were over 100 times greater than that which would result from a person's ingesting 30 ml (2 capfuls) of Welwash oral rinse per day.
Pediatric Use
Clinical effectiveness and safety of Welwash oral rinse have not been established in children under the age of 18.
Carcinogenesis, Mutagenesis, and Impairment of Fertility
In a drinking water study in rats, carcinogenic effects were not observed at doses up to 38 mg/kg/day. Mutagenic effects were not observed in two mammalian in vivo mutagenesis studies with Welwash. The highest doses of Welwash used in a mouse dominant-lethal assay and a hamster cytogenetics test were 1000 mg/kg/day and 250 mg/kg/day, respectively. No evidence of impaired fertility was observed in rats at doses up to 100 mg/kg/day.
What happens if I miss a dose of Welwash?
Use the missed dose as soon as you remember, but brush your teeth first. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
