How To Avoid Drug Interactions
- Bring all of your medications with you, in their original bottles, to each office visit.
- Keep in mind that over-the-counter medications and nutritional supplements may also interact with some drugs and your doctors should be aware of any herbal treatments or vitamin supplements you are taking.
- Make sure that all of your providers are aware of all of the medications you are using, not just the drugs they are prescribing.
How Does A Contraceptive Implant Work
The implant slowly releases a progestin hormone called etonogestrel into the body. Progestin prevents pregnancy by blocking the release of eggs from the ovaries. It also thickens cervical mucus to prevent sperm from entering the uterus.
If you get the implant during the first five days of your period, its immediately effective against pregnancy. If the implant is inserted at any other point, you should use a backup form of birth control for seven days.
Which Birth Control Methods Do Not Contain Estrogen
So, what can women who are unable to use birth control containing estrogen use to prevent pregnancy? The good news is that there are a variety of other birth control methods available, both hormonal and nonhormonal.
- The most reliable forms of birth control without estrogen are the copper intrauterine device , the hormonal IUD, the implant, and sterilization for women or men.
- Nonhormonal methods include the copper IUD, condoms for men or women, cervical cap, and diaphragm.
- Three progestin-only hormonal methods are safe to use: the minipill, the birth control implant, or the hormonal IUD. However, the birth control shot is not recommended for women who have poorly controlled high blood pressure.
If you do have high blood pressure, exercise and dietary changes remain an important component of maintaining your heart health. Discuss with your doctor which birth control options might be best for you, so that you and your doctor can engage in shared decision-making about your preferences.

Can Nasal Spray Flu Vaccine Give Me Flu
Flu vaccines do not cause flu illness. The nasal spray flu vaccine contains weakened viruses, so that they will not cause flu illness. The weakened viruses are cold-adapted, which means they are designed to only multiply at the cooler temperatures found within the nose, and not the lungs or other areas where warmer temperatures exist.

Progestins Reduce Memory Cd8+ T Cell Responses Against A Heterologous Iav Challenge
Although antibody responses to the primary ma2009 H1N1 infection were significantly lower in P4- and LNG-treated female mice than placebo-treated female mice, antibody-mediated immunity is not the primary mechanism of cross protection against different groups of IAVs, which possess distinct surface antigens but share common core proteins that could be recognized by T cells. Populations of memory T cells mediate cross protection against different groups of IAVs and were analyzed at several time points prior to and after challenge with the H3N2 IAV to determine if suppressed memory T cell numbers and activity in progestin-treated female mice may underlie the increased susceptibility to heterosubtypic infection. Treatment with either P4 or LNG did not alter the numbers of total virus-specific CD4+ T cell, Th2 cell, or Th17 cell subsets in the lungs but reduced the numbers of Th1 cells after challenge . The frequencies of total CD8+ T cells and naive CD8+ T cells also were not significantly different between placebo-, P4-, and LNG-treated mice prior to or after heterosubtypic IAV challenge .
Virus Infection Quantification And Purification
Mouse-adapted influenza A virus A/California/04/09 and a mouse-adapted A/California/04/09 drift variant containing the K166Q mutation of the HA sequence were used. Viral RNA was extracted from existing ma2009 IAV and transcribed into cDNA . HA-specific cDNA was PCR amplified and purified on a 1% agarose gel. Purified HA cDNA was digested and cloned into the pHH21 plasmid vector . The K166Q HA mutation was introduced by site-directed mutagenesis . Viruses whose genomes encoded the K166Q HA mutation were generated entirely from cDNA using a 12-plasmid rescue system . The HA sequence of the rescued virus was confirmed by sequencing the coding region of the HA gene. Viral stocks were generated by infecting Madin-Darby canine kidney cells at a multiplicity of infection of 0.01, and the infected cell supernatant was collected at 72 h postinfection. A/Hong Kong/2/68 was given to us courtesy of Innocent N. Mbawuike. All three viruses were used in these studies, and infectious virus titers were determined using the 50% tissue culture infective dose assay. For infections, mice were anesthetized with a ketamine and xylazine cocktail and inoculated intranasally with 30 l of a low dose of the ma2009 virus or mock infected with Dulbecco modified Eagle medium alone. For challenge experiments, animals were inoculated with 30 l of a lethal dose of HK68 or ma2009dv at 6 weeks following the initial infection.

Serum And Bal Fluid Sample Collection
Serum and bronchoalveolar lavage fluid samples were collected at relevant time points to measure antibody and neutralizing antibody titers. Mice were bled from the cheek for the survival experiments or from the retro-orbital sinus for terminal procedures. Serum was heat inactivated at 56°C for 30 min and stored at 80°C. For BAL fluid collection, the mice were euthanized by cervical dislocation and the lungs were lavaged twice with 0.5 ml of a 0.9% saline solution. The BAL fluid was centrifuged at 500 ×g for 10 min to remove cells and debris, and the supernatant was collected, heat inactivated at 56°C for 30 min, and stored at 80°C.
Can Infants Who Have Flu Continue To Breastfeed
Yes. When an infant has flu, the mother should be encouraged to continue breastfeeding or feeding expressed breast milk to her infant. Infants who are ill need fluids to stay hydrated and breast milk is the best option. Expressed breast milk can also be given from a cup, syringe, or bottle if the infant is unable to breastfeed directly at the breast.

Birth Control And High Blood Pressure: Which Methods Are Safe For You
- By Huma Farid, MD, Contributor
Three effective forms of birth control contain the hormone estrogen: the birth control patch, combined hormonal birth control pills, and a vaginal ring. Doctors have typically recommended that women avoid birth control with estrogen if they have high blood pressure, which current US guidelines define as 130 mm Hg systolic pressure and 80 mm Hg diastolic pressure, or higher. A recent clinical update in JAMA clarifies whether its safe for some women with high blood pressure to use these forms of birth control.
How Do I Use A Contraceptive Implant
You must see your doctor to get an implant. After conducting a physical exam, theyll insert the implant under the skin of your upper arm. It can stay in place for up to three years. Implant insertions take just a few minutes. Theyre done with local anesthetic, which makes the procedure painless.
After insertion, youll be sent home with a small bandage covering the insertion site. You may also be given a pressure bandage that you can remove after 24 hours. Some bruising, scarring, pain, or bleeding at the insertion site may occur after the procedure.
The contraceptive implant will stop working after three years.

When To Begin Taking Birth Control Postpartum
When you begin birth control depends on the method chosen. In general, you will want to start using birth control a few weeks after giving birth.
Timing matters when it comes to inserting an IUD since the chance of the implant being expelled is dependent on how soon after birth it is inserted. The best options are to get the IUD immediately after delivery, which poses a 10% risk of expulsion, or to wait four weeks postpartum, when the risk drops to 4% overall.
You can have an implant inserted immediately after a vaginal birth or a cesarean section, and you can get birth control injections immediately after giving birth as well.
Combination birth control pills should be introduced later on, when milk supply is well established, at around four to six weeks.
The cervical cap, diaphragm, and sponge can typically be used starting at six weeks postpartum.
How Antibiotics Might Affect Birth Control
Some types of antibiotics have the potential to affect birth control because they can alter the bodys hormone levels. Hormonal birth control methods that these antibiotics might impact include:
- The pill
- The ring
- The shot
All four of these birth control methods contain the hormones estrogen and/or progestin which thickens the mucus in the cervix, making it difficult for sperm to fertilize an egg, and thin the lining of the uterus to reduce the chance of getting pregnant. The methods that contain estrogen also prevent you from ovulating, while progestin-only methods stop ovulation but not consistently. Certain antibiotics can lower the levels of estrogen and progestin in your body, potentially to the point of affecting your birth control.
Theoretically, antibiotics might also reduce your birth controls efficacy by interrupting the recirculation of estrogens in the body a process called enterohepatic circulation. They do this by killing the bacteria in the small intestine that help break the hormone down and redistribute it within the body.
For these reasons, many manufacturers have historically placed warnings on antibiotic labels to inform women about this risk. Over the years, scientists have done many studies on various types of antibiotics effects on hormonal birth control to determine which ones you should and should not take at the same time.

How Is The Implant Inserted
First, your doctor or nurse will ask you some questions about your health to see if the implant also called Nexplanon is a good method for you. They may also give you a physical exam.
The doctor or nurse gives you a shot to numb a small area of your arm. Then, they use a special inserter tool to slide the implant under your skin. Putting the implant in only takes a few minutes.
Hiv Medications Or Antiretrovirals
These medications are used to prevent the HIV virus from multiplying and keep it under control.
Antiretrovirals that interact with birth control: There is a risk of interaction with all ARVs.
Antiretrovirals that dont interact with birth control: The good news is that there are some safe contraception-ARV combinations. Your doctor can make recommendations on a case-by-case basis.
Safest contraception options: In most cases, the birth control shot , hormonal IUD , and copper IUD are all safe to use on HIV treatment. Non-hormonal methods are another safe alternative.

When Should You Not Get A Flu Shot
If you are currently experiencing flu-like symptoms including a fever, tell your healthcare provider before getting a flu shot. It may be recommended to wait until you are feeling better. People who have severe allergies to any vaccine ingredients should not get a flu shot. People with egg allergies should talk to their healthcare provider prior to getting the vaccine.
Can The Flu Shot Cause Miscarriage
There is no link between flu shots during pregnancy and miscarriages. A recently published study by The Centers for Disease Control and Prevention investigated the risk of miscarriage in pregnant women who were vaccinated in three flu seasons . The study did not find an increased risk of miscarriage after the flu shot.
An earlier study conducted during the flu seasons of 2010-2011 and 2011-2012 found a correlation between flu shots during pregnancy and increased risk of miscarriage. However, the study was limited and the sample size was small, which could have led to imprecise results.
Both CDC and the American College of Obstetricians and Gynecologists recommend that pregnant women get vaccinated for the flu, since the flu poses a danger to pregnant women and the vaccine can protect them from serious illness.

What Can I Do About The Side Effects
Theres no way to control what side effects you experience, but you can take steps to help manage them. Here are some common side effects and tips for management:
- Insomnia or trouble sleeping. Going to bed and waking up at the same time every day can help prevent insomnia. It may also help to avoid afternoon caffeine and naps, even if you feel tired.
- Depression, anxiety, and other changes in mood. A therapist can offer support for these symptoms, whether they relate to the shot or not. Therapy offers a safe space to talk through your feelings and concerns and learn coping strategies to navigate changes in mood.
- Weight gain. If youre concerned about weight gain while using the shot, eating a balanced diet and getting regular physical activity can help but these changes can have benefit no matter what. Taking a more body-neutral approach can also make a difference.
What To Do If You Need To Take Antibiotics While On Birth Control
If your health care provider prescribes you an antibiotic and youre concerned about it affecting your birth control, simply use a backup form of birth control during and a week after treatment. These include:
- A diaphragm .
- Spermicide .
- A cervical cap .
You might also talk to your medical team about switching to nonhormonal birth control, such as a copper intrauterine device . This small device can be placed in your uterus to prevent sperm from reaching and fertilizing an egg. The copper essentially acts as a spermicide.
If your health care provider prescribes you a rifamycin, always use a backup method of birth control, such as a condom or diaphragm, when having vaginal sex. Use one of these backup methods for the entire length of your treatment, plus a week after finishing the antibiotic.
If you are taking an antibiotic to treat a sexually transmitted infection such as gonorrhea or chlamydia, then you might need to avoid having sex during and immediately after treatment. Your Nurx medical provider can provide with the exact recommendations for each.
