Management of Side Effects

Most side effects are temporary and generally harmless and resolve when discontinuing this medicine. However, if you experience any severe side effects or worsening of any of the symptoms, please consult your doctor.

• Consuming plenty of water can help manage some of these side effects. If symptoms persist or worsen, consult your doctor.

Use in Driving and Operating Machinery

• Caffeine, being a stimulant, generally does not impair the ability to drive or operate heavy machinery. However, if you feel jittery or uneasy after consuming caffeine, it is best to refrain from such activities.

Use in Pregnancy and Lactation

• It is recommended that pregnant women limit their caffeine intake to less than 300 mg per day due to potential effects on foetal circulation. The use of caffeine while breastfeeding should be discussed with your doctor as caffeine can pass into breast milk.

Caution in Other Conditions

• Individuals with heart conditions should exercise caution when consuming caffeine as it can cause irregular heartbeat in some cases.

• Those with gastrointestinal issues like diarrhoea or Irritable Bowel Syndrome (IBS) should also be mindful as caffeine can exacerbate these conditions.

Special Dietary and Lifestyle Recommendations

• Maintain hydration, especially when consuming caffeinated beverages as they can have diuretic effects.
