Pubic lice are easy to treat — you usually don’t even need a doctor’s prescription. You can get over-the-counter pubic lice treatment at a drugstore, or from your nurse or doctor.

What’s the treatment for pubic lice?

Pubic lice treatments are easy to use and come in gels, shampoos, liquids, and foam. Most are sold over-the-counter in drugstores, so you can buy them without getting a prescription from a doctor first. Common brands are A-200, Rid, and Nix. Follow the directions that come in the package carefully. You may need to use the treatment more than once.

You can get stronger medicines for pubic lice with a prescription. If you have lice in your eyebrows or eyelashes, you need a special kind of treatment that you can only get from your nurse or doctor. If you’re pregnant or breastfeeding, talk to your nurse or doctor before using any treatment.

Anyone you’ve had intimate contact with should treat themselves at the same time, so you don’t pass crabs back and forth. Always use freshly-washed clothes, towels, and bedding after you finish treatment.

What do I need to do to get rid of pubic lice?

Even after you finish the treatment, most of the nits (lice eggs) will stay stuck to your hairs. You can pick them off with your fingernails or a fine-toothed comb.

Along with using medication, wash or dry clean all of your bedding and towels. Also wash or dry clean any clothing that you wore while you had crabs. Wash these fabrics on the hottest setting, and dry them on the hot cycle for at least 20 minutes.

You can also put fabrics that can’t be washed in a sealed bag for 2 weeks, until the crabs and their eggs die out. You can also vacuum rugs and furniture. You don’t need to call an exterminator or fumigate your home.

Tell your sexual partners and anyone else you’ve had intimate contact with during the last month that they may have crabs. You should all treat yourselves at the same time so you don’t re-infect each other. And don’t have sex or any other kind of intimate contact until everyone finishes their treatment and knows their crabs are gone for good. It’s also a good idea to get tested for other STDs.

If you still see live lice after 9-10 days, do the treatment again. And make sure you’ve washed everything you needed to, and that your sexual partners did the treatment too. If the crabs still don’t go away, talk to your nurse or doctor.

Is there a home remedy for public lice?

Home remedies like hot baths or shaving don’t work. Treatments that soothe itching (like hydrocortisone cream) can help you feel better, but they won’t cure your crabs. The only thing that will actually get rid of your crabs for good are medicines meant to kill pubic lice. 

Trying to treat your pubic lice with home remedies can make your infection worse, and waiting to treat your pubic lice can make it more likely that you’ll spread the crabs to other people. 

Pubic lice are easy to treat — you usually don’t even need a prescription. You can get over-the-counter pubic lice treatment at a drugstore, or from your nurse or doctor.

More questions from patients:

How long does pubic lice live on clothes?

Pubic lice (crabs) feed on human blood. So if one falls off your body, it usually dies within 1–2 days. However, their eggs can take about 6–10 days to hatch. So if an egg is on your clothing or bed sheets, that can cause another infection. 

To get rid of pubic lice and their eggs, machine wash and dry your clothes and bed sheets in hot water (at least 130°F) and the high heat drying cycle. Clothes and other things that aren’t washable can be dry-cleaned or sealed in a plastic bag and stored for 2 weeks (until the lice and eggs die out).

Summary

Read the full fact sheet

• Pubic lice are usually sexually transmitted through direct skin-to-skin contact.
• Pubic lice do not voluntarily leave the body and will need to be treated with a cream or lotion that contains permethrin.
• Do not use insecticides used in the home as these will not work and may damage your skin.
• Lice infestation causes no serious harm.
• If you have pubic lice it is a good idea to be tested for other sexually transmissible infections.

About pubic lice

Pubic lice, or crab lice, infest pubic hair. They can also sometimes affect the hair of the armpit, eyebrows, eyelashes, beard and torso. The infection is also called pediculosis pubis and the lice are called Phthirus pubis.

Pubic lice are small, flat, light-brown parasites that cling to pubic hair and suck blood for nourishment. Blood sucking from pubic lice can cause small red areas or sores and itching.

Pubic lice are usually transmitted through direct skin-to-skin contact during sexual activity. However, they can also be spread by contact with towels, undergarments and bedding of an infected person.

Lice infestation causes no serious harm, but can be irritating. If you have pubic lice, it is a good idea to get tested for other sexually transmissible infections.

Symptoms of pubic lice

The main symptom is itching of the affected area. This is often worse at night. Lice and nits (eggs from the lice) can sometimes be seen, especially stuck to the pubic hairs.
Some people have no symptoms and may be unaware that they have a lice infestation.

Diagnosis of pubic lice

Pubic lice are diagnosed by careful inspection of the affected area.

Treatment of pubic lice

Applying topical creams or lotions containing permethrin (for example, Lyclear cream or Quellada lotion) to the whole body from neck to toes is the most commonly recommended treatment. You do not need to apply the cream to the hair on your head. See your doctor, pharmacist or sexual health centre for further advice.

Note: Do not apply permethrin to your eyelashes. If your eyelashes are affected, discuss alternative treatment with your doctor.

Treatment tips for pubic lice

You can treat pubic lice more effectively if you:

• read and follow the instructions on the medication carefully
• make sure your skin is cool, clean and dry when you apply the cream
• treat your whole body from neck to toes, including the perineum (the skin between the vagina and the anus) and the anal area. You don’t need to apply the cream to head hair
• leave the cream on overnight and wash it off the next morning
• wash clothing, towels and bedding at the same time as applying the treatment (hot machine washing and drying is enough)
• repeat the treatment after one to two weeks as it’s not effective against unhatched eggs. Eggs hatch in 6–10 days
• avoid close personal contact until you and your sexual contacts or partners are treated.

Symptoms may take a few days to settle. If you still have symptoms one week after treatment, see your doctor for review.

Sexual partners should be treated for pubic lice

Any sexual partners you have had over the past month will need to be examined and treated. Current sexual partners should be treated at the same time as you are. Condoms do not protect you against pubic lice.

Coronavirus: why do pharmacists need the blue blood of horseshoe crabs and how will it help the Covid-19 vaccine?

They have ten eyes, are 60 centimeters long, have lived on Earth for more than 300 million years, and they actually have pale blue blood, which is highly valued in pharmacology and saves our health .

No, this is not science fiction, but ordinary, good old science. Meet horseshoe crabs, or, as they are also called, horseshoe crabs – although, strictly speaking, they are not actually crabs, but their closest relatives are arachnids.

People are very dependent on horseshoe crabs, or rather, on their blood, which, among other things, is used to determine the purity of medicines, and now also to create a potential coronavirus vaccine.

However, every medal has a downside, in this case it is the life of the horseshoe crabs themselves, who also have their blood (in fact, hemolymph, which is actually a cross between blood and lymph).

Therefore, wildlife conservationists want to end the practice of “milking” these crabs (let’s call them that for convenience).

What are the benefits of horseshoe crabs?

Some of us quite possibly owe our lives to these creatures and don’t even know it

The blood of these “living fossils” has a unique property: it coagulates when it enters even the smallest amount of pathogenic bacteria or other foreign microorganisms, turning into jelly. Thus, the immune system of horseshoe crabs protects other organs from damage.

Using an extract made from the cells of this hemolymph, testing new medical preparations, scientists can be absolutely sure that bacteria or their metabolic products have not got into them, which can then harm a person.

Only horseshoe crab blood possesses this amazing property.

Therefore, every year, thousands of these crabs are caught at sea and sent to American laboratories, where some of their blood is taken and then released into the wild.

The reagent extracted from the hemolymph of horseshoe crabs is highly valued – the cost of one liter of Limulus amebocyte lysate is about 15 thousand dollars, which makes it one of the most expensive medicines in the world.

What happens to “donors” afterwards

but these animals.

At first, experts thought that almost all horseshoe crabs survived this forced donation. Another ability of these sea creatures is that they give exactly as much blood as they can give without harming their health.

However, according to recent estimates, up to 30% of individuals die as a result of this procedure.

Other studies have shown that after blood sampling, female crabs are less likely to mate.

Scientists estimate the age of horseshoe crabs at 300-450 million years, which makes them one of the oldest species on Earth.

“Right now they are milking about half a million crabs,” lamented Dr. Barbara Brammer, who leads an environmental group in New Jersey, where most of the American horseshoe crabs are caught.

In an interview with the BBC she lamented that no one does not know exactly how blood sampling affects the future life of crabs after they are released.0005

As a result, American horseshoe crabs are approaching the threshold beyond which they can be officially considered endangered.

At the same time, large pharmaceutical companies point to statistics, according to which the number of horseshoe crabs has remained at the same level over the past summer.

Is it possible to find an artificial substitute?

Research to create an artificial analogue of horseshoe crab hemolymph extract has been going on for a long time, but the real breakthrough came only in 2016.

Scientists have succeeded in creating a substitute that has been approved for use in Europe. Some American pharmaceutical companies have also begun to use it.

The blood of these “living fossils” is indeed blue due to its high copper content.

What’s the problem then?

And the fact is that in June of this year, the organization responsible for the safety of medicines in the United States (Food and Drug Administration, or FDA), said that it could not guarantee that the substitute works as reliably as like a natural product.

Therefore, all companies that sell their drugs in the US are required to use horseshoe crab blood for purity testing.

The same goes for any potential coronavirus vaccine: whoever invents it will be required to test it in the old tried and true way if they want to sell their product to millions of Americans.

Dr. Brammer wants to force the American authorities to reconsider their approach, especially since in other countries the artificial substitute is already widely used.

“We need to stop depending on this natural source,” she says .

Some pharmaceutical companies claim they can meet the demand for a coronavirus vaccine without multiplying their crab harvest.

However, according to Barbara, there are at least 30 companies working on the vaccine, and each of them will be required to conduct testing.

“That’s why I’m very worried about horseshoe crab populations,” says Dr. Brammer. “They’re a key part of the ecosystem.”

Antidepressant crabs | Russian Geographical Society

September 5, 2022

In this material we will talk about the completely unusual consequences of our everyday actions. Pharmacology* in the hydrosphere and how it gets there.

The media are increasingly publishing shocking data on the pollution of water bodies with pharmaceutical substances. So, antidepressants, ibuprofen and antibiotics were found in the organisms of sea creatures in Antarctica. All this not only affects the physical condition of representatives of the aquatic fauna, but also the behavior of entire ecosystems. The concentration of a given substance may vary from area to area; from metropolis to metropolis.

How do all these medicines get into water bodies in such a colossal amount? The answer is simple. The source of pollution is the toilets of ordinary citizens. Many substances do not completely break down in our body and are naturally excreted into the outside world through sewers. An important role is played by a peculiar “tradition” of flushing medicines down the toilet.

In Oregon, scientists have recorded the strange behavior of crabs. They behaved very boldly, paid little attention to food, were not afraid of natural enemies and “bull” at relatives. Their dementia and courage made them easy prey for predators. In the body of arthropods found a large concentration of antidepressants.

Here is another example of the effects of massive drug consumption. British scientists conducted a large-scale study of more than 50 fresh water bodies and found that a third of male amphibians have caviar. The reason for the transgender, bisexual behavior of frogs and some types of fish turned out to be hormonal drugs that English women use in large quantities.

Based on the nature of wastewater, one can easily form a picture of the use of drugs in various regions. This is already a clear demonstration of social problems that also affect the environment.

However, the most serious problems are problems at the micro level . Many types of antibiotics are weakly susceptible to degradation under the influence of environmental factors. Antibiotics are available over-the-counter, and people use them to self-medicate at every sign of illness. As a result, tons of medicines enter water bodies, destroying the microflora of both ecosystems and animals living in them, and also kill plankton. Antibiotics in sewers affect the operation of sewage treatment plants – after all, bacteria are also used there. All these problems can affect us directly. At high concentrations of antibiotics in the environment, bacteria and microbes can adapt to their effects. As a result, when leaving the natural focus, this or that infection may already have resistance (addiction) to drugs.

Who is to blame and what to do? Let’s not blame each individual person for the fact that he uncontrollably uses antibiotics, antidepressants and flushes them down the drain. Let’s leave such methods of manipulation to large corporations. The problem is systemic, the problem is in the legislation, in the work of treatment facilities and unscrupulous pharmaceutical companies that promote the uncontrolled consumption of medicines even for minor reasons.
