Important Safety Information Regarding Compounded Semaglutide Products

Please be aware that compounded drugs are not FDA-approved and do not undergo clinical studies to evaluate for safety and efficacy, similar to FDA-approved commercially available products. Compounded products may still be legally prescribed, and your healthcare provider may issue you a prescription for compounded semaglutide based on your medical consultation.

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used for chronic weight management, along with a reduced calorie diet and increased physical activity, for people with an initial body mass index (BMI) of:

  • 30 kg/m2 or greater (obesity) or
  • 27 kg/m2 or greater (overweight) in the presence of at least one weight-related comorbid condition (e.g., hypertension, type 2 diabetes mellitus, or dyslipidemia).

Speak with your healthcare provider to see if semaglutide may be right for you.

Semaglutide may cause serious side effects, including:

  • Possible thyroid tumors, including cancer. Tell your healthcare provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer. In studies with rodents, semaglutide caused thyroid tumors, including thyroid cancer. It is not known if semaglutide will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in humans.

Who should not use semaglutide:

  • Do not use semaglutide if you or any family member has ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
  • Do not use semaglutide if you have had a serious allergic reaction to semaglutide in the past.

Before starting semaglutide, tell your healthcare provider if you have any other medical conditions, including if you:

  • Have or have had problems with your pancreas or kidneys.
  • Have type 2 diabetes and a history of diabetic retinopathy.
  • Have or have had depression, suicidal thoughts, or mental health issues.
  • Are pregnant or plan to become pregnant. Semaglutide should not be used during pregnancy and there may be potential risks to an unborn baby from exposure to semaglutide during pregnancy. You should stop using semaglutide for at least 2 months before you plan to become pregnant.
  • Are breastfeeding or plan to breastfeed. It is not known if semaglutide passes into your breast milk.

Tell your healthcare provider about all the medicines you take. This includes prescription medications, over-the-counter medicines, vitamins, and herbal supplements. Semaglutide may affect the way some medicines work, and some medicines may affect the way semaglutide works.

  • Paralysis of the stomach (gastroparesis). The symptoms of gastroparesis may include feeling full shortly after starting a meal, feeling full long after eating a meal, nausea, and vomiting. Contact your healthcare provider if you experience any of these symptoms.
  • Inflammation of your pancreas (pancreatitis). Stop using semaglutide and contact your healthcare provider immediately if you have severe pain in your stomach area (abdomen) that will not go away, with or without vomiting.
  • Gallbladder problems. Semaglutide may cause gallbladder problems, including gallstones. Some gallstones may need surgery. Contact your healthcare provider if you have symptoms, such as pain in your upper stomach (abdomen), fever, yellowing of the skin or eyes (jaundice), or clay-colored stools.
  • Increased risk of low blood sugar (hypoglycemia) in patients with type 2 diabetes. Signs and symptoms of low blood sugar may include dizziness or light-headedness, blurred vision, anxiety, irritability or mood changes, sweating, slurred speech, hunger, confusion or drowsiness, shakiness, weakness, headache, fast heartbeat, or feeling jittery. Talk to your healthcare provider about how to recognize and treat low blood sugar and check your blood sugar before you start and while you take semaglutide.
  • Kidney problems (kidney failure). In people who have kidney problems, diarrhea, nausea, and vomiting may cause a loss of fluids (dehydration), which may cause kidney problems to get worse. It is important for you to drink fluids to help reduce your chance of dehydration.
  • Serious allergic reactions. Stop using semaglutide and seek medical attention if you have any symptoms of a serious allergic reaction, including swelling of your face, lips, tongue, or throat; problems breathing or swallowing; severe rash or itching; fainting or feeling dizzy; or very rapid heartbeat.

Genital herpes — suppression (immunocompetent)Take Valacyclovir 1 gram by mouth once daily; or 500 mg once daily if ≤9 recurrences/year (provider-directed).

Herpes zoster (shingles)Take Valacyclovir 1 gram by mouth 3 times daily for 7 days. Start as early as possible; most effective within 48 hours of rash onset.

Dose adjustments are required for reduced kidney function — consult a medical provider.

Pregnancy: Pregnancy Risk Category B (see Appendix A). Use only if potential benefit justifies potential risk. Discuss with a medical provider.

Breastfeeding: Acyclovir (active metabolite) is present in breast milk. Discuss with a medical provider whether benefits outweigh risks.

Notes: Valacyclovir does not cure herpes infections. It does not prevent all transmission — use safer sex practices. Start therapy as early as possible for best effect. Maintain adequate hydration. Not a substitute for medical evaluation of severe, disseminated, or ocular herpes.

Common Side Effects: Headache, nausea, and abdominal pain are most common. Other effects may include dizziness, vomiting, diarrhea, fatigue, rash, and menstrual symptoms. Serious reactions can include acute kidney injury, central nervous system effects (confusion, agitation, hallucinations, seizures — higher risk in elderly or reduced kidney function), and thrombotic thrombocytopenic purpura / hemolytic uremic syndrome (TTP/HUS) reported with very high doses in immunocompromised patients.

Contraindications: Clinically significant hypersensitivity (e.g., anaphylaxis) to valacyclovir, acyclovir, or any component of the formulation.

Caution: Use with caution and dose-adjust in kidney impairment; elderly patients are at higher risk of CNS adverse effects. Seek urgent care for decreased urine output, severe confusion, unusual bruising/bleeding, severe rash, or swelling of face/lips/tongue.

VALACYCLOVIR HCL

Appendix A: Pregnancy, Lactation, and Reproductive Potential Labeling

Purpose of This Appendix

This appendix summarizes how pregnancy, breastfeeding, and reproductive potential information should be interpreted in medication education materials. This appendix is based on the FDA Pregnancy and Lactation Labeling Rule (PLLR) framework for prescription drug labeling.

The FDA no longer uses the pregnancy letter categories A, B, C, D, and X in current prescription drug labeling. These categories were removed because they were considered confusing and overly simplistic and did not adequately communicate medication risk during pregnancy, lactation, or reproductive decision-making.

Current FDA labeling uses narrative risk information to help healthcare providers assess benefit and risk and counsel pregnant patients, breastfeeding patients, and patients of reproductive potential.

8.1 Pregnancy

Under current FDA labeling, the Pregnancy subsection may include the following elements when applicable:

Pregnancy Exposure RegistryIf a pregnancy exposure registry exists for a medication, labeling may include information about the registry and how pregnant patients may enroll or obtain additional information.

Risk SummaryThe pregnancy risk summary provides a concise summary of what is known about medication use during pregnancy. It may include available human data, animal data, and pharmacologic information when relevant.

The risk summary may address whether available data identify a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.

Clinical ConsiderationsThis section may include clinically relevant information such as:

  • Disease-associated maternal and/or embryo/fetal risk
  • Dose adjustments during pregnancy and postpartum period
  • Maternal adverse reactions
  • Fetal/neonatal adverse reactions
  • Labor or delivery considerations when applicable

DataThis section may summarize the human and/or animal data supporting the risk summary.

8.2 Lactation

Under current FDA labeling, the Lactation subsection may include the following elements when applicable:

Risk SummaryThe lactation risk summary may describe:

  • Whether the medication is present in human milk
  • Whether the medication affects the breastfed child
  • Whether the medication affects milk production
  • Relevant human or animal lactation data, if available

When human lactation data are available, FDA labeling gives priority to human data over animal data. If breastfeeding is contraindicated, that information should be stated first in the risk summary.

Clinical ConsiderationsThis section may include recommendations for minimizing exposure, monitoring the breastfed child, or managing potential adverse reactions when applicable.

DataThis section may summarize available human or animal lactation data, including measured drug levels in milk or infant exposure estimates when available.

8.3 Females and Males of Reproductive Potential

Under current FDA labeling, this subsection may include information about:

  • Pregnancy testing
  • Contraception
  • Infertility

This section is included when a medication may affect pregnancy status, fertility, embryo-fetal development, or reproductive decision-making.

Legacy Pregnancy Letter Categories

The FDA has removed the pregnancy letter categories A, B, C, D, and X from prescription drug labeling. These categories may still appear in older reference materials, older product labels, or legacy clinical documents, but they are not the current FDA labeling standard.

When a legacy category appears in this medication guide, it should be interpreted only as historical labeling language. Current prescribing information should be reviewed for the most up-to-date pregnancy risk summary.

Legacy Category AAdequate and well-controlled studies in pregnant women failed to demonstrate a risk to the fetus in the first trimester, and there is no evidence of risk in later trimesters.

Legacy Category BAnimal reproduction studies failed to demonstrate fetal risk, but there are no adequate and well-controlled studies in pregnant women.orAnimal studies showed an adverse effect, but adequate and well-controlled studies in pregnant women failed to demonstrate fetal risk.

Legacy Category CAnimal reproduction studies showed an adverse effect on the fetus, and there are no adequate and well-controlled studies in humans.orNo animal reproduction studies and no adequate and well-controlled studies in humans are available.

Potential benefits may warrant use in pregnant women despite potential risks.

Legacy Category DThere is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans.

Potential benefits may warrant use in pregnant women despite potential risks.

Legacy Category XStudies in animals or humans demonstrated fetal abnormalities.orThere is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans.

The risks involved in use during pregnancy clearly outweigh potential benefits.

Standard Pregnancy Language for Medication Sheets

Use one of the following FDA-aligned language structures when drafting medication sheets:

When current labeling provides a clear pregnancy risk statementPregnancy: Current labeling states [insert label-based risk summary]. Consult with a medical provider before use during pregnancy.

When human pregnancy data are limitedPregnancy: Available human data are limited and are not sufficient to establish a drug-associated risk. Use during pregnancy only if the potential benefit justifies the potential risk. Consult with a medical provider.

When medication should be avoided at a specific pregnancy stagePregnancy: Avoid use during [insert trimester/week range] unless specifically advised by a medical provider due to [insert label-supported risk]. Consult with a medical provider.

When medication is contraindicated in pregnancyPregnancy: Use is contraindicated during pregnancy. Do not use if pregnant or planning to become pregnant unless labeling or a medical provider specifically indicates otherwise.

Standard Breastfeeding Language for Medication Sheets

Use one of the following FDA-aligned language structures when drafting medication sheets:

When medication presence in human milk is unknownBreastfeeding: It is not known whether this medication is present in human milk, whether it affects the breastfed infant, or whether it affects milk production. Consult with a medical provider before use while breastfeeding.

When medication is present in human milkBreastfeeding: This medication is present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for treatment and any potential adverse effects on the breastfed child. Consult with a medical provider.

When medication is expected to produce low infant exposureBreastfeeding: Available data suggest infant exposure through breastmilk is expected to be low. Consult with a medical provider before use while breastfeeding, especially when nursing a newborn or preterm infant.

When breastfeeding is not recommendedBreastfeeding: Breastfeeding is not recommended during treatment with this medication and for [insert duration, if specified in labeling] after the last dose. Consult with a medical provider for individualized guidance.

When breastfeeding is contraindicatedBreastfeeding: Use is contraindicated during breastfeeding. Do not breastfeed during treatment unless current prescribing information or a medical provider specifically indicates otherwise.

Standard Disclaimer

This appendix is for medication education and labeling consistency only. It does not provide medical advice, diagnose any condition, recommend treatment, or replace the full prescribing information, product label, FDA-approved labeling, or guidance from a licensed medical provider. Current prescribing information should be reviewed because pregnancy, lactation, and reproductive-risk information may change as new data become available.
