1. What is Sativex and what is it used for
What is Sativex
Sativex is an oral spray solution that contains cannabis extracts (called “cannabinoids”).
What is Sativex used for
Sativex is used in multiple sclerosis (MS) to improve symptoms related to muscle stiffness, also called “spasticity”.
The term “spasticity” means that there is an increase in “muscle tone” that makes the muscles feel stiffer or more rigid. This means more difficulty than usual in moving the muscles.
Sativex is used when other medicines have not helped to improve muscle stiffness.
4-week trial period with Sativex
Only a specialist doctor can tell you to start treatment with Sativex.
- Before you start using Sativex, your specialist doctor will do a complete assessment of the severity of your spasticity to assess the degree of muscle stiffness and your response to other treatments.
- Then you will be put on a 4-week trial period with Sativex. After this, your specialist doctor will do another assessment to determine if Sativex is helping you.
- Only if you show significant improvement in symptoms related to spasticity after these 4 weeks can you continue to receive Sativex.
2. What you need to know before you use Sativex
Do not use Sativex:
- If you are allergic to cannabis extracts or any of the other ingredients of this medicine (listed in Section 6).
- If you or someone closely related to you has a history of mental disorder, such as schizophrenia, psychosis, or other major psychiatric disorder. This does not include depression due to your multiple sclerosis.
- If you are breastfeeding.
Do not use this medicine if you have any of the above circumstances. If in doubt, consult your doctor or pharmacist before using Sativex.

Both you and your partner should use reliable contraceptive measures during the use of this medicine (see the section “Pregnancy, breastfeeding, and contraception (men and women)” below).
If you have any of the above circumstances (or are unsure), consult your doctor or pharmacist before using Sativex.
Using Sativex with other medicines
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines, as Sativex may interfere with the action of some medicines. Similarly, some medicines may interfere with the action of Sativex.
In particular, tell your doctor or pharmacist if you are using medicines for:
- anxiety or insomnia (sedatives or hypnotics such as benzodiazepines, e.g., diazepam or triazolam; other sedatives, e.g., zopiclone, zolpidem, buspirone, St. John's Wort (a herbal preparation))
- muscle spasms (such as baclofen)
- bacterial infections (antibiotics such as rifampicin, clarithromycin)
- epilepsy or nerve pain (such as phenytoin, phenobarbital, carbamazepine)
- high cholesterol (known as statins; e.g., atorvastatin or simvastatin)
- fungal infections (such as itraconazole, fluconazole, and ketoconazole)
- HIV infection (e.g., ritonavir)
- blood thinning (known as coumarins; e.g., warfarin)
- heart problems (known as beta-blockers; e.g., bisoprolol, propranolol)
- corticosteroids for inflammation (such as hydrocortisone, beclometasone, prednisolone)
- certain hormonal medicines used for contraception or for some types of cancer (such as ethinylestradiol, levonorgestrel, or dydrogesterone)
- anesthesia to put you to sleep and relax your muscles before surgery (such as propofol)
If you have any of the above circumstances (or are unsure), consult your doctor or pharmacist before using Sativex.
If you go to see another doctor or go to hospital, tell them what medicines you are using.
Using Sativex with food, drinks, and alcohol
- Generally, you should avoid drinking alcoholic beverages during the use of Sativex, especially at the start of treatment or when changing the dose. If you drink alcoholic beverages while using Sativex, keep in mind that taking alcohol and Sativex together may increase the effects of both (causing loss of balance or altered response), which could increase the risk of falls and other accidents.
- You can use Sativex with or without food (see the section “How to use Sativex”).
Pregnancy, breastfeeding, and contraception (men and women)
- If you are pregnant, think you may be pregnant, or are planning to have a baby, consult your doctor or pharmacist before using this medicine.
Do not use Sativex during pregnancy, unless your doctor tells you to. Sativex may affect the effectiveness of contraceptive methods, such as the “pill” or contraceptive implants. This means you should use an additional contraceptive method.
- Both you and your partner should use a reliable barrier method of contraception, such as a condom, diaphragm, or cervical cap, while using this medicine and for at least 3 months after stopping treatment.
- Do not use Sativex during breastfeeding.
Driving and using machines
- Do not drive or operate machinery when you first start taking Sativex or until you are taking a stable daily dose.
- Sativex may cause drowsiness or dizziness, which may affect your judgment and ability to perform tasks that require skill. On rare occasions, it may cause a brief loss of consciousness.
- Even if you are used to taking Sativex and your dose is stable, do not drive or operate machinery if Sativex causes effects such as drowsiness or dizziness that may affect your ability to perform these tasks. If in doubt, do not drive or operate machinery.
Consult your doctor or pharmacist if you are unsure whether it is safe to drive while taking this medicine.
Traveling abroad with Sativex
- Before traveling abroad, you must check if it is legal to take this medicine into the countries you are visiting or passing through.
- Sativex is a controlled drug, so its legal status will vary depending on the country.
- Driving during treatment with Sativex may be illegal in some countries.
Sativex contains ethanol and propylene glycol
- This medicine contains up to 40 mg of ethanol (alcohol) per spray. The amount of alcohol in the maximum daily dose for most people (12 sprays) is equivalent to about two teaspoons (10 ml) of beer and approximately one teaspoon (5 ml) of wine. The small amount of alcohol in this medicine will not have a noticeable effect. The alcohol content should be taken into account in the case of pregnant or breastfeeding women, children, and high-risk groups, such as patients with liver disease or epilepsy.
- This medicine contains 52 mg of propylene glycol in each spray. Propylene glycol may cause skin irritation.
3. How to use Sativex
Follow the instructions for administration of this medicine contained in this leaflet or as directed by your doctor. Consult your doctor or pharmacist if you have any doubts.
Sativex is for oral use only: on the inside of the cheek or under the tongue.
- You can use Sativex with or without food. However, using Sativex with food may affect the amount of medicine absorbed by the body. As much as possible, try to use Sativex in the same way in relation to food, so you will always get the same effect.
Opening the spray and preparing it for use
- Take the spray out of the refrigerator (see the section “Storing Sativex”).
- Write the date you open the spray on the label provided at the end of the leaflet. Once opened, do not use the spray for more than 6 weeks (42 days).
- Gently shake the spray container before use.
- Remove the protective cap.
- Hold the spray between your thumb and index finger, and place your middle finger on the nozzle.
- Keep the container upright, then do 2 or 3 sprays onto a paper tissue until a fine spray appears. These sprays are to “prepare” the pump and make sure it is working correctly.
- The spray is now ready to use. You do not need to do any more preparation sprays until you open a new spray container.

Using the spray
- Hold the spray between your thumb and index finger, and place your middle finger on the nozzle.
- Keep it upright and direct it towards your mouth. Place the nozzle under your tongue or towards the inside of your cheek. Vary the place where you spray to avoid discomfort in one area.
- Press the nozzle firmly. Do not do more than one spray at a time, even if it seems like a small amount is sprayed.
- Put the protective cap back on.

If you accidentally spray into your eyes, rinse them immediately with water.
- Do not inhale the product.
- Do not apply the product near children or animals.
- Do not use the spray near open flames or heat sources.
Determining the right dose
The number of sprays you need per day depends only on you. Each person needs a different number of sprays to get the most relief from muscle stiffness with the fewest side effects.
- When you start treatment with Sativex, you should follow the days and hours indicated in the table provided below to determine what is the optimal number of sprays for you.
- Stop increasing the sprays when you have determined the optimal number of sprays for you.This may take a few days to 2 weeks. Do the same number of sprays each day. Distribute the sprays evenly throughout the day.
- Do not do more than one spray at a time. You should always wait at least 15 minutes between each spray.
- Do not overexert yourself during the first few days of using Sativex until you know how it affects you.
- If you start to feel side effects (usually dizziness), do one spray less each day until you get the most relief from symptoms with the fewest side effects.
- Once you have determined what is the optimal number of sprays for you, do the same number of sprays each day. Distribute the sprays evenly throughout the day, according to your needs. However, you should always wait at least 15 minutes between each spray.

If you use more Sativex than you should
If you accidentally use more medicine than you should, you may:
- see or hear things that do not exist (hallucinations)
- feel dizzy, drowsy, or confused
- notice changes in heart rate
If you have used more Sativex than you should, tell your doctor or pharmacist. You can also contact the Toxicology Information Service, phone 91 562 04 20, stating the medicine and the amount used.
If you forget to use Sativex
- If you forget a dose, use a spray as soon as possible or when you notice you need a spray.
- Do not use 2 sprays at the same time to make up for a forgotten dose.
How to know if the spray is almost empty
Once you have done the 3 preparation sprays, the spray contains 90 measured sprays. When the spray starts to run out, the sound of the spray may change. The spray may also have a different taste. This is because the spray is almost empty. When this happens, you should open a new spray container.
If you stop using Sativex
If for any reason you decide to stop treatment with Sativex, tell your doctor or pharmacist. If you stop treatment suddenly, you may experience effects such as disturbed sleep, appetite, or mood for a short period. Generally, muscle stiffness will return gradually when you stop treatment with Sativex.
If you have any other questions about the use of this medicine, ask your doctor or pharmacist.
