Nipent contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per vial; it is essentially "sodium-free".

3. How to use Nipent

Nipent will be administered under the supervision of a specialist doctor.

Dose

Your doctor will know exactly how much you need based on your height, weight, and health status. The usual dose for adults, including the elderly, is 4 mg/m² of body surface area, once every two weeks. This medicine will be administered as a short injection or as a long intravenous infusion (drip) into a vein over 20 to 30 minutes.

Before and after administration of Nipent, you will receive an intravenous solution (glucose or saline) to ensure that your body is full of fluid. This will help the medicine reach the place where it is needed and reduce side effects.

Duration of treatment

You will be treated with Nipent until the cancer cells are destroyed. Your doctor will review you 6-12 months after starting treatment with Nipent to see if you have responded to it.

If you use more Nipent than you should

If you receive a dose of Nipent higher than recommended, important organs (brain, liver, kidney, lung) may be affected, and a serious medical condition may occur. If you experience any of the symptoms listed below, contact your doctor immediately, as this may be a life-threatening medical emergency: confusion; drowsiness; seizures; loss of consciousness for a period; pain, burning, numbness, or tingling in the hands or feet; weakness in the arms or legs, loss of ability to move the arms or legs, or visual and auditory disturbances (difficulty concentrating and tinnitus).

You may also notice: yellowing of the skin and whites of the eyes (jaundice); itching; pain in the upper right abdomen; rash, fatigue, and weakness, or loss of appetite. Other symptoms may include: frequent urination, especially at night (nocturia); swelling of the legs and swelling around the eyes (fluid retention); difficulty breathing, dry cough, and general discomfort when breathing or worsening of symptoms when lying on your back.

4. Possible side effects

Like all medicines, Nipent can cause side effects, although not everyone gets them.

Nipent works by eliminating cancer cells, but sometimes it also eliminates normal blood cells, which can increase the risk of infection. It can also decrease the number of platelets (necessary for blood clotting). Your doctor will monitor your condition and inform you if this occurs. There are certain precautions you should take to reduce the risk of infection or bleeding. If possible, avoid contact with people who have infections.

• Tell your doctor immediatelyif you think you have an infection or if you have a fever, sweats, or chills, cough or hoarseness, difficulty breathing, mouth sores or lip sores, inflamed nose and runny nose, breast pain, lower back pain or pain on one side, inability or difficulty urinating (passing water), headache with confusion (encephalitis).
• Tell your doctor immediatelyif you experience any abnormal bleeding, nosebleeds, or bruising, black stools, blood in urine or stools, red spots on the skin, throat sores, jaundice (yellowing of the eyes and skin, pale stools, or dark urine), allergic reactions (e.g., severe rash, difficulty breathing, runny nose, facial swelling, painful sores in the mouth), tremors, spasms, severe chest pain that may also affect your arm and neck (heart attack).
