1. What Sanomigran Tablets are and what they are used for
Sanomigran Tablets are available in two different strengths containing either 0.5 mg or 1.5 mg of the
active ingredient, pizotifen.
Sanomigran Tablets are a migraine treatment. They may help to stop the effects of certain naturally
occuring substances in your body called “serotonin”, “histamine” and “tryptamine” which are involved
in causing some kinds of headache, including migraine.
Sanomigran Tablets have been prescribed for you by your doctor to help your migraine type
headaches. If they are taken regularly they can help to prevent headaches or reduce the pain of
cluster headaches, common and classical migraine. Sanomigran Tablets can stop some migraine
attacks starting and help make other attacks less severe. They will not stop migraine attacks once
they have started.

3. How to take Sanomigran Tablets
The doctor will decide what dose of Sanomigran Tablets you should take. Always take the tablets
exactly as your doctor has told you to. The dose will be on the pharmacist’s label. Check the label
carefully. It should tell you how many tablets to take, and how often. If you are not sure, ask your
doctor or pharmacist. Keep taking the tablets for as long as you have been told unless you have any
problems. In that case, check with your doctor.
With Sanomigran Tablets, you do not wait for a migraine and then treat the pain. You take it
regularly to stop your migraines even beginning or to make them less severe.
The usual dose is 1.5 mg of pizotifen each day. This is one 1.5 mg tablet or three 0.5 mg
tablets. You may have been told to take your tablets once a day or as three smaller doses.
Do not take more than 3 mg in a single dose (two 1.5 mg tablets or six 0.5 mg tablets). Do not
take more than 4.5 mg (three 1.5 mg tablets or nine 0.5 mg tablets) in a day.
Children (aged over 2 years)
Children can take up to 1.5 mg of pizotifen each day. This is three 0.5 mg tablets. This is
usually best given in two or three smaller doses.
Do not use the 1.5 mg tablets for children. Do not give them more than 1 mg in a single dose.
This is two 0.5 mg tablets.
For children over 2 who find it difficult to take tablets Sanomigran is also available as an elixir (syrup).
Sanomigran Tablets and Elixir should not be given to children under 2 years of age.
Taking Sanomigran Tablets
Swallow the tablets whole. Have a drink with them if this helps you to swallow.
If you take Sanomigran Tablets once a day, take them in the evening a few hours before you
go to bed as any drowsiness will help you to sleep.
If you take your tablets in two or three doses, spread them evenly through the day.
Carry on taking your Sanomigran Tablets even when you feel well. Your headaches may come back if
you stop taking them. Do not stop taking them suddenly, or you may experience withdrawal
symptoms, such as feeling anxious, shaking, insomnia, feeling sick and blackouts. Talk to your doctor
if you want to stop taking your tablets.
What if you forget to take a dose?
If you forget to take your tablets, do not worry. If you normally take Sanomigran Tablets several times
a day you should take the last dose you missed as soon as you remember. Do not take it if there is
less than 4 hours before your next dose, but go back to your regular dosing schedule. Do not double
doses or take more than your maximum daily dose.
If you normally take one tablet each day take the dose as soon as you remember. Take your next dose
as usual. Do not take more than your maximum daily dose.
Tell your doctor if you keep forgetting to take your tablets.
What if you take too many tablets?
All tablets can be risky if you take too many. If you take too many Sanomigran Tablets at once,
tell your doctor or hospital casualty department as soon as possible. Take your medicine pack
with you so that people can see what you have taken.
If you stop taking Sanomigran
Do not change or stop the treatment without first asking your doctor. Your doctor may want you to
reduce the dosage gradually before stopping completely. This is to prevent any worsening of your
condition and reduce the risk of withdrawal symptoms such as depression, trembling, nausea,
anxiety, generally feeling unwell, dizziness, sleep disorder and weight loss.
