About Clostop SRx Tablet

Clostop SRx Tablet is used to treat dysmenorrhea (period pain) and menorrhagia (heavy menstrual bleeding). Menstrual cramps, also known as dysmenorrhea, are characterized by cramps and pain during menstruation. Menorrhagia is a condition with abnormally heavy or prolonged bleeding during menstruation/periods.

Clostop SRx Tablet is a combination of Tranexamic acid and Mefenamic acid. Tranexamic acid helps the body's natural blood clotting process by preventing fibrin breakdown, which stops blood clot formation. Mefenamic acid works by blocking the effect of chemical messengers that cause pain.

In some cases, you may experience certain common side effects such as nausea, vomiting, diarrhoea, indigestion, heartburn, and headache. Most of these side effects do not require medical attention. However, talk to your doctor if you experience these side effects persistently.

You are advised to take Clostop SRx Tablet for as long as your doctor has prescribed it for you, depending on your medical condition. Clostop SRx Tablet can be taken with or without food. Do not crush, chew, or break it.

Avoid taking Clostop SRx Tablet if you are allergic to it. Consult your doctor if you are pregnant or breastfeeding. Clostop SRx Tablet may cause dizziness, so drive with caution. Clostop SRx Tablet should not be given to children as safety and efficacy have not been established.

  • Avoid trigger foods: Identify and avoid foods that trigger indigestion, such as spicy, fatty, or acidic foods.
  • Stay upright after eating: Sit or stand upright for at least 1-2 hours after eating to prevent stomach acid from flowing into the oesophagus.
  • Avoid carbonated drinks: Avoid drinking carbonated beverages, such as soda or beer, which can worsen indigestion.
  • Manage stress: To alleviate indigestion, engage in stress-reducing activities like deep breathing exercises or meditation.
  • Consult a doctor if needed: If indigestion worsens or persists, consult a healthcare professional to adjust the medication regimen or explore alternative treatments.
