What is Kerasal?

Salicylic acid is a keratolytic (peeling) drug. Salicylic acid triggers the shedding of the skin's outer layer. Urea can be described as an emollient (skin softening agent). Urea aids in moisturizing the skin. A combination of salicylic acid and topical urea (for the face) can be utilized to soften and eliminate rough, scaly skin that is caused by warts or calluses, keratosis, or psoriasis. Kerasal can be used for other purposes that are not mentioned in this guide.

Side effects of Kerasal

Contact a medical professional immediately. If you experience any of the following symptoms that indicate reactions to an allergen: hives; trouble breathing; or swelling of your lips, face, and tongue. Stop taking Kerasal and consult your doctor immediately if you experience serious side effects like redness or severe skin irritation following the application of the drug. The less serious side effects could include minor irritation, itching, or irritation of the treated skin. This isn't an exhaustive list of possible side effects, and other side effects could be present. Consult your physician to seek medical advice on the effects. You can report any side effects to the FDA at 1-800-FDA-1088.

How to take Kerasal?

Take it exactly as indicated on the label or as directed by your physician. Don't use in greater than smaller amounts or for a longer period than is recommended. Don't use Kerasal in the treatment of any skin problem that hasn't been examined by your physician.

Make sure to clean and dry the area prior to applying the medication. It is important to shake the foam thoroughly before every use. Flip the medicine bottle upside down to release the foam. Apply the medicine to the affected area according to the directions. Avoid using Kerasal on skin that is swollen, red, or infected. It may also cause oozing. This medication may cause unexpected results when you undergo certain tests. Be sure to inform any doctor treating you about your use of kerasal. Utilize kerasal frequently to reap the greatest benefits. Contact your physician if your symptoms do not improve or if they become worse when you take this medicine. Keep at room temperature and away from heat and moisture. Make sure the foam container is kept away from direct flames or extreme heat sources, like an automobile during a hot day. The canister might explode if it becomes too hot. Avoid burning or puncturing the empty container.

What happens if I miss a dose?

Utilize the dose you missed immediately after you recall. Do not take your missed dose if it's nearing the time for the next dose. Don't use any extra medication to replace the missed dose.

What happens if I overdose?

If you have mistakenly eaten the drug, get emergency medical attention or call the Poison Help line at 1-800-222-1222. The risk of overdose is increased with long-term use or with high doses of Kerasal absorbed via the skin. Signs of an overdose with salicylic acid could include extreme dizziness or fatigue, vomiting, diarrhea, rapid breathing, a ringing sound in your ears, and losing your hearing.

What should be avoided?

Wart-removal medicine could be inflammable. Don't use it near high temperatures or flames, like a candle that is burning. Cleanse your hands prior to handling the hair styling device (such as straightening or curling irons). A high temperature could cause the medicine to burn and cause burns to your skin. Don't smoke until your gel has been absorbed by your skin. Beware of getting this medication into your nose, eyes, mouth, rectum, or vagina. If it does happen, you must wash it off with water. Don't use any other medication for the areas you deal with using Kerasal unless your physician tells you to.

Interaction with other drugs

It is unlikely that other medications you take by mouth or inject will affect salicylic acid that is applied topically or urea. However, many medications can interact with each other. Be sure to inform your health professionals about any medications you take, such as prescription and over-the-counter drugs, vitamins, and herbs.
