Spiders are a common sight in our homes and gardens. However, not all spiders are dangerous. However, there are some types of spiders, like the "Black Widow", whose venom can be very harmful to our bodies. Imagine that you are cleaning out a place where there is old stuff at home and suddenly a spider bites you. Today we are going to talk about a special treatment that is given in such a case. That is the antidote, or ``Antivenin'', given to the venom of this black widow spider.
What is this antivenin?
Simply put, this is a special medicine that stops the action of the venom when it enters the body and controls the damage it causes. It's like a soldier going into battle. It protects our body by fighting the enemy called venom.
Antivenin is often made using antibodies found in the blood of animals. For example, a horse is injected with a very small amount of spider venom and the antibodies produced against the venom are then used to make this medicine. That is why doctors ask if you are allergic to horse serum. The main function of this medicine is to minimize the damage caused by spider venom to your body, especially to the nervous system.
Things you need to tell your doctor before treatment
Before starting this treatment, there are a few things you should tell your doctor without hiding anything. This is very important for your safety.
- Allergies: If you have any allergies to this antivenom, horse serum, other medications, foods, dyes, or preservatives, you must disclose them.
- Pregnancy: If you are pregnant or trying to get pregnant, tell your doctor.
- If you are a breastfeeding mother: If you are a breastfeeding mother, you should also inform her.
- Other illnesses and medications: If you have any other illnesses or are taking any medications (including vitamins and traditional medicines), tell your doctor about them.
Remember, the information you provide will help your doctor decide how to safely treat you. So don't hide anything, even the smallest thing.
How is this medicine given?
This is not a medicine you can buy at a pharmacy and take home to use.
This antivenom is only given in a hospital or clinic . That is, by a doctor or trained nursing staff. It is usually given as an injection into a vein (intravenously) or as an infusion, like a saline solution. The entire process takes place under medical supervision.
What to do if the medication is too much?
This is given in a hospital setting so the chances of this happening are very low. However, if you think something has happened, report it to the Emergency Treatment Unit (ETU) immediately. Alternatively, you can call the National Poisons Information Centre at the Colombo National Hospital for advice.
Possible side effects of treatment
As with any medicine, this antivenom vaccine can cause some side effects. Some of these should be reported immediately, while others are not so serious. Let's see what they are.
| Side Effect | Description and what to do |
|---|---|
| Things to tell your doctor or nurse immediately | |
| Serious Allergic Reactions | If you notice any skin rash, hives, itching, swelling of the face, lips, or tongue, report it immediately. This may be an emergency. |
| Breathing Problems | If you feel like you're having trouble breathing or your chest is tight, tell me right away. |
| Other serious symptoms | If you develop a high fever, joint pain, or swollen lymph nodes, you should also report this immediately. |

| Muscle Pain | Muscle aches and pains are normal, but if the pain persists or is severe, talk to your doctor. |
Can there be problems with other medications?
In general, this antivenom vaccine rarely causes problematic interactions with other medications. However, "rarely" does not mean "never." That's why we've said before that it's very important to give your doctor a complete list of all the medications you take (whether they're herbal remedies, vitamins, or supplements).
