Etonogestrel implant is used in women to prevent pregnancy. It is a form of birth control that contains a hormone in a flexible plastic rod about the size of a matchstick. It is effective for 3 years when inserted just beneath the skin of your upper arm.

Etonogestrel stops the release of an egg from your ovary. The mucus in your cervix thickens and may prevent sperm from reaching the egg.

Etonogestrel implant will not protect a woman from sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS). The use of latex (rubber) condoms or abstinence (not having sex) is recommended for protection from these diseases.

Etonogestrel is to be given only by or under the direct supervision of a trained healthcare professional.

• Generic Name: naloxone / pentazocine
• Dosage Forms: n.a.
• Other Brand Names: Talwin NX

Pentazocine and naloxone combination is used to relieve moderate to severe pain.

Pentazocine belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.

Naloxone is an opioid antagonist. It acts on the CNS to block the effects of narcotics, especially the "high'' feeling that makes you want to use them. It will not produce any narcotic-like effects or cause mental or physical dependence.

When pentazocine is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.

This medicine is available only with your doctor's prescription.
