Patient leaflet - Tillogab 100 mg hard capsules
1. What Tillogab is, and what it is used for This medicine has been prescribed for you for:
Various forms of epilepsy (seizures that are initially limited to certain parts of the brain, whether the seizure spreads to other parts of the brain or not). The doctor treating you or your child 6 years of age and older will prescribe Tillogab to help treat epilepsy when the current treatment is not fully controlling the condition. You or your child 6 years of age and older should take Tillogab in addition to the current treatment unless told otherwise. Tillogab can also be used on its own to treat adults and children over 12 years of age.
- Peripheral neuropathic pain (long lasting pain caused by damage to the nerves). A variety of different diseases can cause peripheral neuropathic pain (primarily occurring in the legs and/or arms), such as diabetes or shingles. Pain sensations may be described as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, numbness, pins and needles, etc.
It contains gabapentin which belongs to a class of medicines called Gabapentinoids.
This medicine has been prescribed to you and should not be given to anyone else.
Gabapentinoids can cause dependence, tolerance and addiction, and you may get withdrawal symptoms if you stop taking it or reduce the dose suddenly. Your prescriber should have explained how long you will be taking it for and, when it is appropriate to stop, how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months. If this medicine is being used for the treatment of epilepsy you must continue to take it as prescribed by your doctor.

Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative medication. Taking this medicine regularly, particularly for a long time, can lead to physical dependence and addiction. Your prescriber should have explained how long you will be taking it for and, when it is appropriate to stop, how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months. Physical dependence and addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include:
trouble sleeping, headache, nausea, feeling anxious, diarrhoea, flu-like symptoms, convulsions, nervousness, depression, thoughts of harming or killing yourself, pain, sweating, and dizziness. Your prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms. Your prescriber will ensure that your plan for stopping treatment is tailored to you and can be adapted according to your needs and experience of any withdrawal symptoms.
Gabapentinoids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of gabapentinoids, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death. Dependence
Some people may become dependent on Tillogab (a need to keep taking the medicine). They may have withdrawal effects when they stop using Tillogab or reduce the dose (see section 3, “How to take Tillogab” and “If you stop taking Tillogab”). If you have concerns that you may become dependent on Tillogab, it is important that you consult your doctor.
If you notice any of the following signs whilst taking Tillogab, it could be a sign that you have become dependent.
- you feel you need to take the medicine for longer than advised by your prescriber
- you feel you need to take more than the recommended dose
- you are using the medicine for reasons other than prescribed
- you have made repeated, unsuccessful attempts to quit or control the use of the medicine
when you stop taking the medicine you feel unwell, and
you feel better once taking the medicine again If you notice any of these, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to do this safely. A small number of people being treated with anti-epileptics such as gabapentin have had thoughts of harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Important information about potentially serious reactions
Serious skin rashes including Stevens-Johnson syndrome, toxic epidermal necrolysis and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in association with gabapentin. Stop using Tillogab and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.
Read the description of serious symptoms in section 4 of this leaflet under ‘Contact your doctor immediately if you experience any of the following symptoms after taking this medicine as they can be serious’.
Muscle weakness, tenderness, or pain and particularly, if at the same time, you feel unwell or have a high temperature may be caused by an abnormal muscle breakdown which can be life-threatening and lead to kidney problems. You may also experience discolouration of your urine, and a change in blood test results (notably blood creatine phosphokinase increased). If you experience any of these signs or symptoms, please contact your doctor immediately.
Other medicines and Tillogab
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. In particular, tell your doctor (or pharmacist) if you are taking or have been recently taking any medicines for convulsions, sleeping disorders, depression, anxiety, or any other neurological or psychiatric problems. Medicines containing opioids such as morphine If you are taking any medicines containing opioids (such as morphine), please tell your doctor or pharmacist as opioids may increase the effect of gabapentin. In addition, a combination of gabapentin with opioids may cause sleepiness, sedation, decrease in breathing, or death. Antacids for indigestion
If Tillogab and antacids containing aluminium and magnesium are taken at the same time, absorption of gabapentin from the stomach may be reduced. It is therefore recommended that Tillogab is taken at the earliest two hours after taking an antacid.
Tillogab
is not expected to interact with other antiepileptic drugs or the oral contraceptive pill.
may interfere with some laboratory tests, if you require a urine test tell your doctor or hospital what you are taking. Tillogab with food
Tillogab can be taken with or without food.
Pregnancy, breast-feeding and fertility
- If you are pregnant or think you may be pregnant, you must tell your doctor straight away and discuss possible risks the medicine you are taking might pose to your unborn baby.
- You should not stop your treatment without discussing this with your doctor.
- If you are planning to become pregnant you should discuss your treatment with your doctor or pharmacist as early as possible before you become pregnant.
- If you are breastfeeding or planning to breastfeed, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Tillogab can be used during the first trimester of pregnancy if needed.
If you plan to become pregnant or if you are pregnant or think you may be pregnant, talk to your doctor straight away. If you have become pregnant and you have epilepsy, it is important that you do not stop taking your medicine without first consulting your doctor, as this may worsen your illness. Worsening of your epilepsy may put you and your unborn child at risk.
In a study reviewing data from women in Nordic countries who took gabapentin in the first 3 months of pregnancy, there was no increased risk of birth defects or problems with the development of brain function (neurodevelopment disorders). However, babies of women who took gabapentin during pregnancy had an increased risk of low birth weight and preterm birth.
If used during pregnancy, Tillogab may lead to withdrawal symptoms in newborn infants. This risk might be increased when Tillogab is taken together with opioid analgesics (drugs for the treatment of severe pain).
Contact your doctor immediately if you become pregnant, think you might be pregnant, or are planning to become pregnant while taking Tillogab. Do not suddenly discontinue taking this medicine as this may lead to a breakthrough seizure, which could have serious consequences for you and your baby.
Breast-feeding
Gabapentin, the active substance of Tillogab, is passed on through human milk. Because the effect on the baby is unknown, it is not recommended to breast-feed while using Tillogab.
Fertility
There is no effect on fertility in animal studies. Driving and using machines
Tillogab may produce dizziness, drowsiness, and tiredness. You should not drive, operate complex machinery or take part in other potentially hazardous activities until you know whether this medication affects your ability to perform these activities.
