About Obnyx Capsule

Obnyx Capsule belongs to a group of medicines known as androgen receptor inhibitors. It is used to treat prostate cancer. Cancer is a condition where cells in a specific body part grow and reproduce uncontrollably. The cancerous cells can attack and destroy surrounding healthy tissue, including organs. Prostate cancer is a type of cancer that only occurs in men and affects the prostate gland, a tiny gland under the bladder that produces semen.

Obnyx Capsule contains Enzalutamide, an androgen receptor blocker (inhibitor). Enzalutamide blocks testosterone from reaching prostate cancer cells. Most prostate cancers require testosterone to grow. This can slow the growth of the cancer and may shrink it.

Use this medicine as directed by your doctor. You may sometimes experience trouble breathing (pneumonia), weakness or feeling more tired than usual, back pain, diarrhoea, pain in your joints, swelling (in your hands, arms, legs or feet), muscle or bone pain, muscle weakness, headache, cold-like symptoms, dizziness, high blood pressure and trouble falling or staying asleep (insomnia). Most of these side effects may gradually resolve over time. However, if the side effects persist or worsen, consult your doctor.

Enzalutamide is only for use in men. Men using this Obnyx Capsule must use effective birth control whenever they have sex during your treatment and for three months after their final dose. In rare cases, Obnyx Capsule may cause seizures, so tell your doctor if you have or have ever had seizures. Because of the risk of seizure associated with Obnyx Capsule use, patients should be advised of the risk of engaging in any activity where sudden loss of consciousness could cause serious harm to themselves or others. Consumption of alcohol is strictly avoided.

Uses of Obnyx Capsule

Prostate Cancer

Directions for Use

Swallow it as a whole with water; do not crush or chew it.

Medicinal Benefits

Obnyx Capsule contains Enzalutamide, which belongs to a group of medicines known as androgen receptor inhibitors. Most prostate cancers require testosterone to grow. In men, the testicles produce the majority of testosterone. Adrenal glands (Just above each kidney) produce a small quantity of testosterone. Enzalutamide is preventing testosterone from reaching cancer cells in the prostate. This can inhibit the growth of the cancer and even cause it to shrink.

  • Follow a Bland Diet: Eat easy-to-digest foods to help firm up your stool and settle your stomach. Try incorporating bananas, rice, applesauce, toast, plain crackers, and boiled vegetables into your diet.
  • Avoid Trigger Foods: Steer clear of foods that can worsen diarrhoea, such as spicy, fatty, or greasy foods, high-fibre foods, and dairy products (especially if you're lactose intolerant).

  • Applying heat or cold packs to the affected joint can help reduce pain and inflammation.
  • Please track when joint pain occurs and any factors that may trigger it, and share this information with your doctor to help manage symptoms.
  • If your joint pain is severe or prolonged, consult a doctor to rule out any underlying disorders that may require treatment.
  • Wear compression garments like stockings, sleeves, or gloves to apply pressure and help stop fluid from building up, especially after the swelling goes down.
  • Move around and do exercises to help the fluid circulate, especially in swollen limbs. Ask your doctor for specific exercises.

  • If the swelling does not get better after a few days of home treatment or worsens, consult your doctor right away.
