How to use Clas Capsule

Take this medicine in the dose and duration as advised by your doctor. Clas Capsule may be taken with or without food.

How Clas Capsule works

Clas Capsule works by controlling bacterial infection and supporting recovery of the affected tissue. Amoxycillin and cloxacillin act against bacteria by interfering with their protective cell wall, which stops bacterial growth and leads to their elimination. Serratiopeptidase helps reduce inflammation and swelling at the site of infection, improving tissue healing and comfort. Together, these actions help clear the infection, reduce associated inflammation, and support faster relief from symptoms.

Frequently asked questions

Clas Capsule is usually given for the treatment of bacterial infections. It may be used for infections affecting the respiratory tract, skin, soft tissues, teeth, gums, and other parts of the body caused by susceptible bacteria. It also contains Serratiopeptidase, which helps reduce swelling and inflammation associated with infection.
Clas Capsule contains Amoxycillin and Cloxacillin, which are antibiotics that kill infection-causing bacteria and help stop the infection from spreading. It also contains Serratiopeptidase, an enzyme that helps reduce swelling and inflammation. Together, these ingredients help fight infection and support recovery.
Serratiopeptidase helps reduce swelling, inflammation, and discomfort that may occur around infected tissues. By helping decrease inflammation, it may improve comfort and support the healing process while the antibiotics work to eliminate the bacteria causing the infection.
Yes. Clas Capsule may be prescribed for certain dental infections and gum-related infections caused by bacteria. The antibiotics help treat the infection, while Serratiopeptidase may help reduce associated swelling and discomfort. Follow your doctor's advice regarding treatment and dental care.
Some individuals may start noticing improvement within a few days of treatment. However, the infection may continue to clear even after symptoms begin to improve. Continue taking the medicine for the full duration prescribed by your doctor to help ensure complete treatment of the infection.
Even if you start feeling better, some bacteria may still remain in the body. Stopping treatment too early may allow the infection to return and can make the bacteria harder to treat in the future. Completing the full course helps improve the chances of clearing the infection completely.
No. Continue taking Clas Capsule exactly as prescribed, even if your symptoms improve before the course is finished. Stopping treatment early may result in incomplete treatment of the infection and increase the risk of recurrence.
Some infections may take longer to improve depending on their severity and location. If your symptoms are not improving after a few days, are worsening, or new symptoms develop, contact your doctor. Additional evaluation or a different treatment approach may be needed.
No. Clas Capsule works against bacterial infections and does not treat viral illnesses such as the common cold or most cases of flu. Antibiotics should only be used when prescribed for a confirmed or suspected bacterial infection.
Tell your doctor if you have ever had an allergic reaction to penicillin or similar antibiotics. Since both Amoxycillin and Cloxacillin belong to the penicillin group, this medicine may not be suitable for individuals with a penicillin allergy.
Some individuals may experience diarrhea while taking antibiotics because these medicines can affect the normal bacteria in the gut. Mild diarrhea often improves on its own, but severe, persistent, or bloody diarrhea should be reported to your doctor promptly.
Stop taking the medicine and seek immediate medical attention if you develop a widespread rash, severe itching, swelling of the face, lips, tongue, or throat, or difficulty breathing. These may be signs of a serious allergic reaction that requires urgent treatment.
Yes. In some cases, symptoms may return if the infection is not completely cleared or if a new infection develops. Completing the full course and following your doctor's advice can help reduce the risk of the infection returning.
Contact your doctor if your symptoms do not improve, become worse, or if you develop severe diarrhea, persistent fever, significant swelling, severe skin reactions, or signs of an allergic reaction. Early medical attention can help prevent complications and ensure effective treatment.
