Pharmacist tips for Solosec (secnidazole)

pharmacist
  • Don't pour Solosec (secnidazole) granules into your mouth or try to dissolve the granules in liquids, such as water. The granules don't dissolve. Instead, sprinkle the granules onto applesauce, yogurt or pudding and take by mouth within 30 minutes. You can drink some water afterwards to help you swallow all the medication. Solosec (secnidazole) can be taken without regards to meal.
  • Don't chew or crunch the Solosec (secnidazole) oral granules because doing so can alter how the medication gets absorbed into your body.
  • Don't drink alcohol or eat large amounts of food containing ethanol or propylene glycol while taking Solosec (secnidazole) and for at least 2 days after. Doing so might cause nausea, vomiting, diarrhea, belly pain, dizziness, and headache.
  • Taking Solosec (secnidazole) can raise your risk of getting a vaginal yeast infection. Please talk with your gynecologist if you notice your vagina is red and itchy, you have thick white vaginal fluid, or if you experience pain or burning when you urinate.
  • Don't take Solosec (secnidazole) more often than what your gynecologist directed. Taking this medication long-term can raise your risk of getting a vaginal yeast infection or cause it to not work as well for future infections.
  • Solosec (secnidazole) might get into breastmilk. If you're breastfeeding, you might want to consider pumping and discarding your breast milk while and for 4 days after taking Solosec (secnidazole). Some alternatives you can give your baby in the meantime include previously stored breast milk or formula. If you have any questions, please talk with your child's pediatrician.
  • Your healthcare team might also test you for human immunodeficiency virus (HIV) and other STIs if you tested positive for BV or trich. Having BV or trich can raise your risk for other STIs as well.
  • Take Solosec (secnidazole) exactly as directed by your healthcare team, even if you're feeling better. Not taking a complete treatment can cause this medication to not work as well.
  • To lower your risk of BV, try to limit the number of sexual partners, use condoms every time you have sex, or avoid douching (washing inside of vagina with water and other liquids).
  • If you're taking Solosec (secnidazole) for trich, make sure that your sexual partner(s) also get treated to avoid getting reinfected. In most states, your sexual partner(s) can get a prescription without an appointment. Check with your healthcare team if this is an available option. Don't have sex until you or your sexual partner(s) have finished treatment and have no more symptoms.

Common questions about Solosec (secnidazole)

A study showed that about 58% of people who took Solosec (secnidazole) for BV were considered cured of the infection 1 to 2 weeks after their dose. This means the person has normal vaginal discharge with no fishy odor, as well as laboratory results that show minimal BV-causing bacteria. Keep in mind that everyone responds differently to the medication. Another study showed that some people were considered cured of BV 3 to 4 weeks after their dose of Solosec (secnidazole). If you're taking this medication for BV and your symptoms don't start to improve after a week, talk to your healthcare team.

In clinical studies, most people who took a dose of this medication for BV experienced major improvements in their symptoms or were considered completely cured after 7 to 14 days. Similarly, people who took this medication for trich were also cured after 6 to 12 days. Make sure to take Solosec (secnidazole) exactly as prescribed. It's important to finish your treatment dose since not completing your antibiotic can make your infection come back and become harder to treat.

Solosec (secnidazole) can stay in your system for about 4 days after a single dose. This is estimated base on the half-life of the medication. But half-life can also vary from person to person. It's often affected by many factors, such as age and medical history. Because Solosec (secnidazole) can stay in your body for up to 4 days, it can cause side effects or lead to interactions during this time. For example, Solosec (secnidazole) can pass into breastmilk, so nursing mothers should stop breastfeeding for 4 days after the dose; they're recommended to feed their babies previously stored milk or formula instead.

Solosec (secnidazole) is available in a 2-gram packet of granules. To take this medication, sprinkle the granules onto applesauce, yogurt or pudding and take by mouth within 30 minutes. You can drink some water afterwards to help you swallow all the medication. Make sure you don't chew or crunch the oral granules. Doing so can affect how the medication gets absorbed into your body.

There's not enough research to understand whether Solosec (secnidazole) is safe to take during pregnancy. This medication hasn’t been well-studied in human pregnancies, but animal studies suggest it's unlikely to cause harm. If you're pregnant, please talk with your gynecologist to see whether Solosec (secnidazole) is a good option for you.

Solosec (secnidazole) and metronidazole (Flagyl, Vandazole) are oral nitroimidazole antibiotics that can treat BV and trich, but they're not the same. One main difference is that metronidazole (Flagyl, Vandazole) is a first-choice treatment for both BV and trich, while Solosec (secnidazole) isn't. This is because Solosec (secnidazole) is higher-cost and there aren't enough long-term studies to understand how it compares with existing treatments. Another difference is the length of treatment. While treatment with Solosec (secnidazole) is only one dose, treatment with metronidazole (Flagyl) can take multiple days (typically 5 to 7 days). Talk with your healthcare team if you have more questions about either medication.

Don't drink alcohol or eat foods containing large amount of ethanol or propylene glycol (food additives), such as salad dressing, dried soup or cake mix, during treatment with and for at least 2 days after taking Solosec (secnidazole). Doing so can cause nausea, vomiting, diarrhea, belly pain, dizziness, and headache.

People who took Solosec (secnidazole) have commonly reported vaginal yeast infections. This is because Solosec (secnidazole) kills not only the bad bacteria that cause BV and trich, but it also kills the good bacteria that keep your vagina healthy. When the good bacteria is gone, Candida (a type of yeast) can overgrow and cause a vaginal yeast infection. Talk with your healthcare team if you think you might have a yeast infection and they can talk with you about treatment options.

Risks and warnings for Solosec (secnidazole)

Solosec (secnidazole) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Risk of vaginal yeast infection

Taking Solosec (secnidazole) can raise your risk of getting a vaginal yeast infection. If so, your healthcare team might prescribe a medication to treat the yeast infection. Please talk with your gynecologist if you notice your vagina is red and itchy, you have thick white vaginal fluid, or if you experience pain or burning when you urinate.

Risk of Solosec (secnidazole) not working

  • Risk factors: Taking Solosec (secnidazole) more often or differently than prescribed

Taking Solosec (secnidazole) more often or differently than prescribed can put you at risk for infections that are harder to treat in the future. To make sure that this medication will work well to fight future infections, follow your gynecologist's instruction on when and how long to take Solosec (secnidazole).

Possible risk of cancer

  • Risk factors: Taking Solosec (secnidazole) for a long time

It’s not clear whether or not taking Solosec (secnidazole) for a long time can put you at risk for cancer. Studies show that rats who took metronidazole (Flagyl) (a medication that’s similar to Solosec (secnidazole)) throughout their lifetime were at higher risk for tumors.
