Uses of Sepmax DS

Treatment of Bacterial infections

Benefits of Sepmax DS

In Bacterial infection
Sepmax DS treats the bacterial infection it was prescribed for by killing the bacteria or stopping them multiplying. Finishing the course makes sure the infection does not return.
In Gut infection
Sepmax DS clears the bacteria or other organisms causing diarrhoea, abdominal pain and bloating, so the gut settles.
In Skin infection
Sepmax DS treats infected skin and soft tissue, bringing down redness, swelling and pain.
In Dental infection
Sepmax DS treats infections of the teeth and gums, easing the pain and swelling until your dentist can deal with the cause.

How Sepmax DS works

Sepmax DS Tablet is a combination of two antibiotics: Sulfamethoxazole and Trimethoprim. These antibiotics work by preventing the bacteria from producing folic acid, a nutrient required for bacterial multiplication. Together, they treat your infection effectively.

How to take Sepmax DS

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Sepmax DS Tablet should be taken with or after food.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

If you miss a dose of Sepmax DS Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.

If you take too much

An overdose of this medicine can cause vomiting, severe loose motions and nerve symptoms. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Sepmax DS

Most side effects of Sepmax DS are mild and settle as the body gets used to the medicine. The ones reported most often are:

  • Nausea
  • Metallic taste

  • Stomach pain
  • Headache

Stop the medicine and get help at once for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Warnings and precautions

Report severe or watery loose motions during or after the course rather than treating them yourself. Tetracyclines stain developing teeth and are avoided in young children and in pregnancy. Antibiotics do not work against colds, flu or most sore throats, which are caused by viruses.

Interactions with other medicines

Antacids, iron, zinc and calcium reduce the absorption of tetracyclines — separate them by a couple of hours. Tell your doctor if you take a blood thinner.
