What Gabapentin Orion is and what it is used for

Gabapentin Orion belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long-term pain caused by nerve damage).

The active substance in Gabapentin Orion is gabapentin.

Gabapentin Orion is used to treating:

  • various forms of epilepsy (seizures that are initially limited to certain parts of the brain, with or without spreading to other parts of the brain). Your doctor may prescribe Gabapentin Orion to treat your epilepsy if your current epilepsy treatment does not work well enough. You should take Gabapentin Orion as a supplement to your current treatment, unless your doctor tells you otherwise. Gabapentin Orion can also be used as the only medicine for adults and children from 12 years.
  • peripheral neuropathic pain (prolonged pain caused by nerve damage). A variety of diseases can cause peripheral neuropathic pain (mainly in the legs and / or arms), such as diabetes or shingles . The pain can be described as a hot, burning, throbbing, flashing, stinging, sharp, cramping, aching, stinging, paralyzing sensation or as ant crawls.

Gabapentin contained in Gabapentin Orion may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.

  • If you have diseases of the nervous system, respiratory diseases or if you are older than 65 years, your doctor may prescribe you a different dosage .

Cases of abuse and dependence have been reported for gabapentin since its introduction. Talk to your doctor if you have a history of substance abuse or addiction.

A small number of people who are treated with antiepileptic drugs such as gabapentin have also had thoughts of harming themselves or committing suicide. If you ever get these thoughts, contact your doctor immediately.

Important information about potentially serious reactions

A few patients taking Gabapentin Orion have a severe reaction or potentially severe skin reaction, which can develop into more serious problems if left untreated. You need to know the symptoms you need to be aware of when taking Gabapentin Orion.

Read the description of these symptoms in section 4 of this leaflet under ” Contact your doctor immediately if you get any of the following symptoms after taking this medicine as they may be serious “.

Muscle weakness, soreness, or pain, especially if you also feel unwell or have a high fever, may be due to an abnormal muscle breakdown that can be life-threatening and lead to kidney problems. You may also have discolored urine and altered blood test results (especially elevated blood creatine phosphokinase). Contact your doctor immediately if you experience any of these symptoms.

Other medicines and Gabapentin Orion

Tell your doctor or pharmacist if you have recently taken or might take any other medicines. In particular, tell your doctor (or pharmacist) if you are taking or have recently taken medicines for seizures, sleep disorders, depression, anxiety, or any other neurological or mental problems.

Drugs that contain opioids such as morphine

If you are taking any medicines that contain opioids (such as morphine), tell your doctor or pharmacist, as opioids may increase the effect of Gabapentin Orion. In addition, a combination of Gabapentin Orion and opioids may cause symptoms such as drowsiness and/or decreased breathing.

If Gabapentin Orion is taken with antacids containing aluminum and magnesium, the absorption of Gabapentin Orion from the stomach may decrease. Gabapentin Orion should therefore be taken no earlier than two hours after taking antacids.

Gabapentin Orion should not be taken during pregnancy unless your doctor tells you otherwise. An effective contraceptive must be used by women of childbearing potential.

No studies have been performed to specifically investigate the use of gabapentin in pregnant women, but the use of other epilepsy medicines has been reported to increase the risk of birth defects, especially when more than one such medicine is taken at the same time. As far as possible, you should try not to take more than one epilepsy medication during pregnancy, and only in consultation with a doctor.

Contact your doctor immediately if you become pregnant, if you think you may be pregnant or if you are planning to become pregnant while taking Gabapentin Orion. Do not abruptly stop taking this medicine. This can lead to a breakthrough spasm and have serious consequences for you and your child.
