The Ambiguity of the 'Little Pink Pill'
The question, "What is the little pink pill called?" is common, but it has no single answer. Many manufacturers use the color pink for their medications for branding purposes, to distinguish different dosages, or to prevent errors [1.12.2]. However, this means that dozens of different drugs from various classes can be small, round, and pink. Relying on color as the sole method of identification is extremely dangerous and can lead to taking the wrong medication, incorrect dosage, or experiencing harmful drug interactions [1.10.2].
Why You Can't Trust Color Alone
The U.S. Food and Drug Administration (FDA) requires that most prescription and over-the-counter (OTC) solid oral dosage forms have a unique imprint code [1.12.2]. This code—a combination of letters and/or numbers—is the most reliable feature for identification, along with shape and size [1.9.1]. A pink pill could be anything from a sleep aid to a potent opioid or a heart medication. Taking a medication without being certain of its identity poses significant health risks [1.10.3].
Common Medications That Are Pink
While not exhaustive, several common medications are frequently associated with the 'little pink pill' description. It's important to note that different dosages or generic versions of the same drug may have different appearances [1.12.3].
Diphenhydramine (Benadryl)
Many people associate the 'little pink pill' with over-the-counter antihistamines like Benadryl.
- Drug Class: Antihistamine [1.5.4].
- Primary Use: Treating allergy symptoms, such as sneezing and runny nose, as well as insomnia and motion sickness [1.5.1, 1.5.2].
- Common Side Effects: Drowsiness, dizziness, dry mouth, and blurred vision [1.5.3]. It is generally not recommended for adults over 65 due to increased risk of side effects like confusion and falls [1.5.1].
Sertraline (Zoloft)
Certain dosages of this widely prescribed antidepressant are pink.
- Drug Class: Selective Serotonin Reuptake Inhibitor (SSRI) [1.6.4].
- Primary Use: Treating major depressive disorder (MDD), obsessive-compulsive disorder (OCD), panic disorder, post-traumatic stress disorder (PTSD), and social anxiety disorder (SAD) [1.6.4].
- Dosage Information: Sertraline is available in 25 mg, 50 mg, and 100 mg tablets, among other forms [1.6.2]. The initial adult dose for depression is typically 50 mg per day [1.6.4]. The appearance can vary by manufacturer and strength.
Lisinopril
This common blood pressure medication can come in the form of a pink pill.
- Drug Class: Angiotensin-Converting Enzyme (ACE) Inhibitor [1.7.2].
- Primary Use: Treating high blood pressure (hypertension) and heart failure. It is also used to improve survival rates after a heart attack [1.7.1, 1.7.3]. One version with the imprint E3 is a pink, round 10 mg tablet [1.7.4].
- How it Works: It works by relaxing blood vessels, which lowers blood pressure and increases the supply of blood and oxygen to the heart [1.7.1].
Flibanserin (Addyi)
Marketed specifically as 'the little pink pill,' this medication has a very specific purpose.
- Drug Class: Serotonin 1A receptor agonist/serotonin 2A receptor antagonist.
- Primary Use: Treatment of acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women [1.8.1, 1.8.2]. It is not for enhancing sexual performance or for use in postmenopausal women or men [1.8.4].
- Important Considerations: The FDA requires a warning against consuming alcohol while taking Addyi due to the increased risk of severe low blood pressure and fainting [1.8.2]. It can also interact with many other common medications [1.8.3].
Other Pink Pills
Other medications that may be pink include certain dosages of Oxycodone (a potent opioid pain reliever), Amoxicillin (an antibiotic), and amphetamine/dextroamphetamine (used to treat ADHD) [1.2.1, 1.4.1].
How to Safely Identify an Unknown Pill
Never consume a medication you cannot identify with 100% certainty. Follow these steps for accurate identification:
- Examine the Imprint Code: Look for any letters, numbers, or logos stamped on either side of the pill. This is the most crucial piece of information [1.12.3].
- Use an Online Pill Identifier: Reputable health websites like Drugs.com, WebMD, and Medscape offer free tools where you can enter the imprint code, shape, and color to find a match [1.9.2, 1.13.1]. These tools provide images for visual confirmation.
- Consult a Professional: The safest method is to take the pill to a pharmacist. They can use their professional resources and your medication history to provide a definitive identification [1.12.3].
- Call Poison Control: If you suspect an accidental ingestion or overdose, call the Poison Help Line at 1-800-222-1222 immediately [1.9.2].

|---|---|---|---|
| Diphenhydramine | Antihistamine | Allergies, Insomnia [1.5.2] | Often an oval pink tablet (e.g., imprint '44 329') [1.2.1] |
| Sertraline (Zoloft) | SSRI Antidepressant | Depression, Anxiety Disorders [1.6.4] | Appearance varies by dosage and manufacturer. |
| Lisinopril | ACE Inhibitor | High Blood Pressure, Heart Failure [1.7.1] | A round pink 10mg pill may have imprint 'E3' [1.7.4]. |
| Flibanserin (Addyi) | Serotonin Receptor Modulator | Low Sexual Desire in Premenopausal Women [1.8.2] | Marketed as 'the little pink pill'; do not take with alcohol [1.8.2]. |
| Oxycodone | Opioid Analgesic | Moderate to Severe Pain [1.2.2] | A round pink 10mg pill may have imprint 'K 56' or 'M 10' [1.4.1, 1.4.3]. |
The Dangers of Misidentification
Taking an unidentified medication is a gamble with serious potential consequences. Risks include:
- Adverse Drug Interactions: An unknown pill could interact dangerously with other medications you are taking [1.10.2].
- Allergic Reactions: You could have a severe allergic reaction to an active or inactive ingredient in the pill [1.10.2].
- Incorrect Dosage: Taking the wrong dose of a medication can lead to ineffectiveness or overdose [1.10.3].
- Worsening Medical Conditions: A pill could exacerbate an underlying health problem, such as a heart or kidney condition [1.10.3].
Conclusion
While many people colloquially refer to 'the little pink pill,' no single medication owns this description. The color of a pill is an unreliable and dangerous way to identify it. The only safe and accurate method for identifying a medication is by using its unique imprint code, in combination with its size and shape, and confirming with a professional resource or pharmacist. Never take a medication unless you are absolutely certain what it is and that it was prescribed for you.
