Precautions & Cautions
To minimize the risk of severe side effects, it is crucial to adhere to your doctor's instructions regarding dosage and frequency of application. Using more of the medication than prescribed, or using it more often or for a longer period than recommended, can increase the risk of adverse effects.
When applying this medication, avoid using it on sunburned skin, cuts, scrapes, eczema, or damaged skin. Instead, practice good skin care and take precautions to protect your skin from the sun, as this medication can make you more susceptible to sunburn. To reduce this risk, avoid exposure to sunlight, sunlamps, and tanning beds, and use sunscreen and lip balm with a Sun Protection Factor (SPF) of 15 or higher when outdoors. Additionally, wear protective clothing and eyewear to shield your skin from the sun. Certain weather conditions, such as cold and wind, may also irritate your skin; consult your doctor or pharmacist for guidance on how to protect your skin in these situations.
Be aware that contact with lime peels may cause adverse effects, and using other skin products in conjunction with this medication can increase the risk of irritation. Before using any other skin products, including soaps, consult your doctor to discuss potential interactions.
If this medication causes dry skin, you may use a moisturizer; however, consult your doctor or pharmacist to determine the most suitable type of moisturizer for your skin. You can use makeup unless your doctor has advised against it; if you do use makeup, ensure that you clean the area to be treated before applying this medication.
In the event that this medication is swallowed, seek immediate medical attention by calling a doctor or poison control center. Additionally, if you are pregnant or plan to become pregnant, inform your doctor, as this medication may harm the unborn baby. If you are breastfeeding, consult your doctor to discuss any potential risks to your baby.

Special Patient Groups
Pregnancy
Category C. Use only if the potential benefit justifies the potential risk to the fetus. While systemic absorption is minimal, oral retinoids are highly teratogenic. Avoid use during pregnancy if possible.
Trimester-Specific Risks:
Lactation
Minimal systemic absorption is expected, making transfer into breast milk unlikely to be clinically significant. Use with caution. Consider applying after breastfeeding and avoiding application to areas where the infant may come into direct contact with the treated skin.
Pediatric Use
Approved for use in patients 9 years of age and older. Safety and effectiveness in pediatric patients younger than 9 years have not been established.
Geriatric Use
No specific dose adjustments are necessary. However, geriatric patients may have more fragile skin and may be more susceptible to irritation. Use with caution and monitor for skin reactions.
Clinical Information
Clinical Pearls
- Altreno is a lotion formulation of tretinoin, which may be better tolerated than other tretinoin formulations (creams, gels) due to its moisturizing base.
- Patients should be advised that an initial worsening of acne (purging) may occur during the first few weeks of treatment.
- Consistent daily use is key for efficacy; skipping doses can delay results.
- Emphasize strict sun protection due to increased photosensitivity.
- Start with a small amount and gradually increase if tolerated to minimize irritation.
Alternative Therapies
- Other topical retinoids (e.g., adapalene, tazarotene)
- Topical antibiotics (e.g., clindamycin, erythromycin)
- Topical antimicrobials (e.g., benzoyl peroxide, azelaic acid)
- Oral antibiotics (e.g., doxycycline, minocycline)
- Oral isotretinoin (for severe, recalcitrant acne)
- Hormonal therapies (e.g., oral contraceptives, spironolactone)
- Chemical peels
- Laser/light therapies
