1. What Toptabs are and what they are used for

Toptabs contains the active ingredients Aspirin and Caffeine. Aspirin belongs to a group of medicines called the non-steroidal anti-inflammatory drugs (NSAIDS). Caffeine acts as a mild stimulant.

Toptabs provide relief from cold and flu symptoms, including sore throat pain, headache, feverishness and aches and pains.

It also provides relief of mild to moderate pain including migraine, neuralgia, toothache, sore throat, period pain and rheumatic pain.

2. What you need to know before you take Toptabs

Do not take Toptabs if you:

  • Are allergic to aspirin or salicylates, caffeine, any other medicines known as NSAIDs or to any of the other ingredients of this medicine (listed in Section 6);
  • Have had an allergic reaction after taking ibuprofen or aspirin;
  • Have had asthma or shortness of breath in response to aspirin before;
  • Suffer from high blood pressure or heart disease;
  • Have ever had a stomach ulcer, perforation or bleeding of the stomach;
  • Have blood clotting disorders (e.g. Haemophilia) or have ever had gout;
  • Have liver or kidney disease;
  • If you are in the last three months of your pregnancy, you must not use higher doses than 100 mg per day (see section “Pregnancy, breast-feeding and fertility”).

If any of the above applies to you, speak to your doctor before taking these tablets.

Warnings and precautions

Talk to your doctor or pharmacist or nurse before taking Toptabs if:

  • You suffer from asthma, high blood pressure or allergic disease;
  • You suffer from any kidney or liver disorder;
  • You have haemolytic anaemia (reduction in red blood cells which can make the skin pale yellow and cause weakness or breathlessness) with a G6PDH deficiency;
  • You experience any unusual bleeding (Aspirin may cause bleeding);
  • You think you are dehydrated (you may feel thirsty with a dry mouth).

When taking acetylsalicylic acid, serious allergic reactions which may include chest pain and even heart attack (Kounis syndrome) have been reported (see section 4). Seek medical care immediately when you notice chest pain with allergic reactions (such as skin rashes, shortness of breath).

Children and adolescents

Do not give to children under 16 years of age unless your doctor tells you to. Aspirin can cause Reye’s syndrome when it is given to children. This is a very rare disease but it can be fatal. Do not give aspirin to children under 16 of age unless your doctor tells you to.

Other medicines and Toptabs

Tell your doctor or pharmacist if you are taking, have recently taken or might take any of the following medicines:

  • Medicines to thin your blood/prevent clotting (e.g. warfarin, heparin, phenindione);
  • Medicines to treat gout (e.g. probenecid, sulfinpyrazone);
  • Medicines to prevent organ rejection after transplantation (e.g. ciclosporin, tacrolimus);
  • Medicines to treat high blood pressure (e.g. ACE-inhibitors such as captopril, carbonic anhydrous inhibitors such as acetazolamide, beta-blockers such as atenolol);
  • Medicines for the treatment of pain and inflammation (e.g. anti-inflammatory medicines such as ibuprofen, diclofenac or steroids);
  • Medicines for cancer or rheumatoid arthritis (e.g. methotrexate);
  • Medicines to treat peptic ulcers and reflux (e.g. pantoprazole, rabeprazole);
  • Medicines used to treat depression (e.g. fluoxetine and paroxetine);
  • Medicines to treat epilepsy (e.g. Phenytoin or sodium valproate);
  • Medicines to treat diabetes (e.g. Insulin or sulfonylurea hypoglycaemic agents);
  • Medicines used to pass water (e.g. furosemide, bendroflumethiazide);
  • Metamizole (substance to decrease pain and fever) may reduce the effect of acetylsalicylic acid on platelet aggregation (blood cells sticking together and forming a blood clot), when taken concomitantly. Therefore, this combination should be used with caution in patients taking low dose aspirin for cardioprotection.

Toptabs with food, drink and alcohol

Drinking alcohol at the same time as taking aspirin increases the risk of bleeding. Avoid excessive intake of caffeine (e.g. coffee, tea and some canned drinks) while taking this product.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Toptabs are best avoided in late pregnancy and during breastfeeding as they may prolong labour and cause bleeding in the newborn. Ask your doctor or pharmacist for advice before taking any medicine.

If you continue or start treatment with Toptabs during pregnancy per instruction of the physician, then use Toptabs as advised by your doctor and do not use a higher dose than is recommended.

Pregnancy - last trimester

Do not take Toptabs higher than 100 mg per day if you are in the last 3 months of pregnancy as it could harm your unborn child or cause problems at delivery. It can cause kidney and heart problems in your unborn baby. It may affect your and your baby’s tendency to bleed and cause labour to be later or longer than expected.

If you take Toptabs at low doses (up to and including 100 mg per day), you need strict obstetric monitoring as advised by your doctor.

Pregnancy – first and second trimester

You should not take Toptabs during the first 6 months of pregnancy unless absolutely necessary and advised by your doctor. If you need treatment during this period or while you are trying to get pregnant, the lowest dose for the shortest time possible should be used. If taken for more than a few days from 20 weeks of pregnancy onward, Toptabs can cause kidney problems in your unborn baby that may lead to low levels of amniotic fluid that surrounds the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the heart of the baby. If you need treatment for longer than a few days, your doctor may recommend additional monitoring.

Toptabs contains Lactose

Toptabs contain small amount of a sugar called lactose. If you have been told by your doctor that you have intolerance to lactose or any other sugars, contact your doctor before taking this medicinal product.
