Nefopam
About Nefopam
Nefopam is an oral prescription medication that helps relieve moderate to severe acute pain when standard over-the-counter pain medicines are not enough. It is prescribed to improve comfort and support a smoother recovery.
To get the best results, it is important to take this medication exactly as prescribed by your doctor. It can be taken with or without food, though taking it with a meal may help reduce minor stomach irritation. Light physical activity and staying well hydrated may also support your recovery.
While taking Nefopam, you may experience common, mild side effects like a dry mouth, lightheadedness, or feeling sick. These symptoms usually go away on their own, but contact your doctor promptly, if you experience serious issues like confusion, a rapid heart rate, or difficulty passing urine.
Before starting this medication, talk to your doctor if you have a history of seizures, glaucoma, or problems emptying your bladder. Do not take this medicine if you have epilepsy or are currently experiencing acute urinary retention, as it can worsen these conditions.
This medicine can interact with alcohol, which dramatically increases drowsiness, and certain other medications, so you should discuss all current treatments with your pharmacist. If you are pregnant, breastfeeding, or over the age of 65, consult your doctor to ensure this treatment is safe for your specific needs.
Availability of Nefopam may vary between countries and formulations. Your doctor will prescribe it only when considered appropriate for your condition.
