Sometimes a doctor prescribes a medicine that you only have to take once, right? This is especially true for certain infections. Today we're going to talk about one such medicine, usually given in a single dose. It's called Secnidazole. You've probably been prescribed this medicine, or you've even heard of it. Let's take a look at what it is, how it's used, and what you need to be careful about.
What is Secnidazole?
Simply put, Secnidazole is an anti-infective drug. This means that it can kill some of the harmful microorganisms in our body. Specifically, it is used to treat infections caused by bacteria and protozoa . For example, doctors often prescribe this drug for conditions such as bacterial vaginosis, which is a common condition in women.
The most important thing is that this medicine does not work for viral infections. That means if you have a viral illness like a cold or flu, taking this medicine will not help. Therefore, you should only use it if prescribed by a doctor, and only for the disease for which it was prescribed.
In Sri Lanka and abroad, this medicine can come under brand names such as SOLOSEC.
Things you need to tell your doctor before taking this medicine
Before your doctor prescribes this medicine, he or she will need to know your complete medical history. Therefore, if you have any of the following conditions, be sure to tell your doctor.
- If you are a regular drinker: This is very important. The way this medicine interacts with alcohol can be dangerous. We will talk about this in more detail later.
- If you are pregnant or trying to get pregnant: Some medications are not suitable during pregnancy, so it is important to inform your doctor about this.
- If you are a breastfeeding mother: The medications you are taking can pass to your baby through breast milk. So it is important to talk about this as well.
- If you have allergies to Secnidazole or other medicines, foods, or dyes: Tell your doctor if you have had an allergic reaction to any medicine in the past.
- Rare medical conditions such as Cockayne syndrome: If you have any rare, long-term medical conditions, tell your doctor about them as well.
How should I use the medicine exactly?
This medicine comes in a packet of granules. It has to be taken in a special way. It is very important to use it exactly as the doctor tells you.
1. First, take the entire dose of medicine in the packet. Do not take half of it. Take the entire dose at once.
2. Add this medicine powder to a thick, soft food like yogurt, skim milk, or pudding and stir well.
3. Stir and swallow this mixture within 30 minutes . Do not leave it for too long.
4. Most importantly: Do not chew this. The mixture should be swallowed whole.
5. If you have difficulty swallowing, you can drink a glass of water afterwards.
6. Never dilute this medicine powder in a liquid such as water, milk, or tea. Doing so may change the effectiveness of the medicine.
What to do if you take too much medicine?
If you accidentally take more than the prescribed dose, go to the nearest hospital Emergency Treatment Unit (ETU) immediately . Alternatively, call the National Poisons Information Centre at the Colombo National Hospital for advice.
What are the possible interactions with this medicine?
There is one thing you need to be extremely careful with when taking this medicine. That is alcohol.
Do not consume alcohol or anything containing alcohol while taking Secnidazole and for a few days after taking it.
This includes not only alcohol, but also other products that contain alcohol, such as some mouthwashes and some cough syrups. If you take them, you may experience severe reactions such as severe nausea, vomiting, stomach cramps, dizziness, and flushing. So be very careful with this.
If you are taking any other medications, vitamins, or herbs, tell your doctor about them all, as some things may interact with this medicine.
Side effects that may occur when taking medication
Like any medicine, Secnidazole can cause some side effects. However, not everyone gets them. Some are serious, while others are common. Let's look at these in a table.
| Side effects of Secnidazole | |
|---|---|
| Serious side effects that you should report to your doctor immediately | |
| Allergic Reactions | Skin rash, itching, swelling of the lips, tongue or face, difficulty breathing. If you notice any of these signs, seek medical advice immediately. |

How do you store and dispose of the medicine?
Store this medicine at room temperature, out of the reach of children and pets. Do not use expired medicine.
When disposing of unused, expired medication, do not throw it directly into the trash. Take the medication out of the container, mix it with something like used tea or coffee grounds, put it in a small bag, seal it well, and throw it in the trash. This is the safest way.
