Hydrosar Capsule
Description
Hydrosar Capsule is a prescription medication used to treat certain types of cancer. It contains hydroxyurea as its active ingredient, which works by slowing or stopping the growth of cancer cells in the body. This helps control the spread of cancer and improve the patient’s condition. Your doctor will determine the correct dose and duration based on your health and response to treatment.
This medicine should be taken exactly as prescribed by your doctor. Do not take more than the recommended dose, and do not stop the treatment suddenly without medical advice. Swallow the capsule with a glass of water at the same time each day for the best results. Regular use as instructed by your doctor helps ensure the medicine is effective against cancer.
Before starting treatment with Hydrosar Capsule, it is very important to inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding. Hydroxyurea can harm the unborn baby, so special precautions are necessary. Also, ensure your doctor is aware of your complete medical history and any other medications you are taking to avoid potential interactions.
While taking Hydrosar Capsule, attend all follow-up appointments and medical tests as advised by your doctor. This helps monitor your blood counts and overall health during treatment. Your doctor may also suggest lifestyle changes and precautions to improve the effectiveness of the therapy and minimise side effects.
Unsupervised use of Hydrosar Capsule without proper monitoring can cause unwanted effects. Never share this medicine with anyone else, even if they have similar symptoms. Always follow your doctor’s advice carefully and contact them if you notice any unusual side effects or concerns during your treatment.
