Product introduction

Keto-B Lotion is only meant for external use and should be used as advised by your doctor. A thin layer of the medicine should be applied only to the affected areas of the skin with clean and dry hands. Wash your hands before and after applying the medicine. If it gets into your eyes, nose, mouth, or vagina rinse with water. It may take several days to weeks for your symptoms to improve, but you should keep using this medicine regularly. The course of the treatment should be completed to ensure better efficacy of the medicine. If your condition does not improve or gets worse, you should talk to your doctor.

This is usually a safe medicine, however, it may cause burning, irritation, itching, and redness at the application site. These side effects are usually mild and self-limiting. Serious side effects are rare. You must consult the doctor if you experience any allergic reaction (rashes, itching, swelling, shortness of breath, etc.).

Before taking this medicine, it is important to tell your doctor if you are taking or have recently taken any other medicines for the same disease or other diseases. Pregnant and breastfeeding women should use this medicine with proper consultation and caution. If you are a known allergic to the medicine, you must refrain from using this medicine. You should consult the doctor about prescribing an alternative medicine for your condition. During the course of the treatment, do not touch or scratch the infected skin areas as this may worsen or spread the infection.

Benefits of Keto-B Lotion

Treatment of Fungal skin infections
Keto-B Lotion is a combination of two medicines, Ketoconazole and Beclometasone, used to treat skin infections caused by fungi. These include infections like athlete’s foot, ringworm, vaginal thrush, and sweat rash. Ketoconazole works by killing and stopping the growth of fungi, thereby clearing the infection and relieving the symptoms. Beclometasone blocks the release of chemicals that cause symptoms such as itching, redness, and swelling. Therefore this medicine relieves the inflammation due to these infections.

You should use this medicine for as long as it is prescribed, even if your symptoms disappear, otherwise they may come back. Depending on the type of infection you are treating, this may be several weeks. Even after your skin is completely cured, you may have to apply it occasionally to prevent the symptoms from returning.

Side effects of Keto-B Lotion

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
Common side effects of Keto-B
  • Application site reactions (burning, irritation, itching and redness)

How to use Keto-B Lotion

This medicine is for external use only. Use this medicine in the dose and duration as advised by your doctor. Shake it well and apply to the area evenly.

How Keto-B Lotion works

Keto-B Lotion is a combination of two medicines: Beclometasone and Ketoconazole, which treats fungal skin infections. Beclometasone is a steroid which blocks the production of certain chemical messengers (prostaglandins) that make the skin red, swollen and itchy. Ketoconazole is an antifungal which stops the growth of fungi by preventing them from forming their own protective covering.

Quick tips

  • This combination medicine helps treat skin infections caused by many different types of fungi.
  • It can take a few weeks for the infection to clear and a few months before the skin returns to its normal color.
  • It is not taken orally, so it does not cause many side effects.
  • Do not cover the area being treated with airtight dressings such as bandages unless directed by a doctor, as this may increase the risk of side effects.
  • It is for use on skin only. Do not use it in your eyes, mouth, or vagina. Rinse with cold water if you accidentally get it in these area.
  • Do not use this medicine more often or for longer than advised by your doctor.

Frequently asked questions

Follow the directions given by the doctor on the medicine. Apply the medicine thinly and in sufficient quantity to cover the affected areas. Keto-B Lotion is usually applied two or three times a day to the affected areas of skin. Wash your hands after using Keto-B Lotion, unless it is used for treating skin infection on the hands.
No, do not stop taking Keto-B Lotion and complete the full course of treatment even if you feel better. Your symptoms may improve before the infection is completely cured.
Keto-B Lotion should not be used on the face. Do not use the medication for longer than advised periods of time. Do not apply a bandage or dressing to the area being treated, as this will increase absorption of the preparation and increase the risk of side effects. This medicine should be used by the patient and never be given to other people even if their condition appears to be the same.
No, Keto-B Lotion will not be more effective if overused. Overusing the medicine can result in too much medicine being absorbed into the body. This may lead to thinning or weakening of the skin and other serious side effects. If you are experiencing increased severity of your symptoms, please consult your doctor for re-evaluation.
Keep this medicine in the packet or the container it came in, tightly closed. Store it according to the instructions mentioned on the pack or label. Dispose of the unused medicine. Make sure it is not consumed by pets, children and other people.
