How much to take

It is recommended that Tramadol Sandoz SR be taken as:

one to two 100 mg tablet(s) twice a day (morning and evening)
one 150 mg or 200 mg tablet twice a day (morning and evening).

It is specially made up into tablets that allow the body to absorb the tramadol over a long period, so that dosing needs only to be twice a day.

As all patients respond to treatment differently, your doctor may start you on a lower dose.

Do not take more than four Tramadol Sandoz SR 100 mg tablets or more than two of the Tramadol Sandoz SR 150 mg or of the 200 mg tablets per day.

Patients over 75 years may need a lower daily dose of Tramadol Sandoz SR compared to younger adults.

Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.

Follow the instructions they give you. If you take the wrong dose, Tramadol Sandoz SR may not work as well and your problem may not improve.

How to take it

Swallow the tablets whole with a full glass of water.

Do not break, chew, crush or dissolve them. Tramadol Sandoz SR are only designed to work properly if swallowed whole. The tablets are designed to release the medicine over a prolonged period. If they are broken, chewed, crushed or dissolved the medicine will be released at once, which can be dangerous and cause serious problems, such as an overdose which may be fatal. Unless stated otherwise, they should be swallowed whole.

When to take Tramadol Sandoz SR

Take your medicine before, during or immediately after a meal, at about the same time each day. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

How long to take Tramadol Sandoz SR

This differs between individuals depending how severe your pain is, how you respond to Tramadol Sandoz SR, and the cause of your pain. Ask your doctor for advice on how long you need to take Tramadol Sandoz SR.

If you forget to take it

Take your dose as soon as you remember, and continue to take it as you would normally. The following dose should be taken after twelve hours, or as prescribed by your doctor.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
