What You'll Learn

Isotretinoin (Accutane) can cause nail fragility
Isotretinoin (Accutane) is a vitamin A derivative known as a retinoid. It is a medication designed to treat severe acne. While it can be very effective in clearing up the skin, there is also the potential for side effects. One of the known side effects of isotretinoin is nail fragility.
A study on the effects of isotretinoin on nail growth and thickness found that it can increase the nail growth rate and thin the nail plate over time. Nail findings were observed in 12.8% of patients, with onychoschizia being the most common. This means that isotretinoin can cause nails to become thinner and more brittle, leading to increased fragility.
The exact mechanism of how isotretinoin affects the nail plate is not yet fully understood. However, it is known that vitamin A can build up in the tissues, which can become a problem. It is important to note that isotretinoin should not be taken with vitamin A supplements.
The side effects of isotretinoin typically fade within a few weeks after discontinuing the medication. However, in some cases, the nail changes may persist even after completing the Accutane course. If you are experiencing nail fragility due to isotretinoin, it is recommended to consult a dermatologist or healthcare provider for advice and to explore possible treatments.
There are some measures that can be taken to mitigate the effects of isotretinoin on nail health. This includes increasing protein intake, using strengthening nail polish, and applying lotions or cuticle oils to the nails and nail beds regularly. Maintaining a consistent nail care routine can also help improve nail health. Additionally, ensuring adequate intake of certain vitamins and minerals, such as B vitamins, vitamin C, omega-3, and calcium, can promote nail growth and strength.

Accutane's effects on nail growth rate and thickness
Accutane, also known as Isotretinoin, is a vitamin A derivative used to treat severe acne. It has various effects on the nails, including changes in growth rate and thickness.
A study examining the effects of Isotretinoin on the nail plate found that it gradually increases nail growth rate and thins the nail plate over time. The median nail growth rate for those taking Isotretinoin was 3.16 mm/month, compared to 2.89 mm/month for the control group. The median nail thickness for the Isotretinoin group was 0.47 mm, while it was 0.50 mm for the control group. These differences were statistically significant, indicating that Isotretinoin has a noticeable impact on nail growth and thickness.
Nail changes were observed in 12.8% of patients taking Isotretinoin, with onychoschizia being the most common finding. Dermatologists should consider these potential nail changes when prescribing Isotretinoin, as they may impact the patient's quality of life. While the mechanism behind Isotretinoin's effects on the nail plate is unknown, it is believed to be related to its action as a retinoid, which can affect nail growth and structure.
Some people who have taken Accutane have reported experiencing brittle and weakened nails, even after completing their course of treatment. This may be due to the drug's impact on nail growth and thickness, as well as its effect on nutrient levels in the body. It is recommended to increase protein intake and ensure sufficient levels of B vitamins, folate, vitamin C, omega-3, and calcium to promote stronger nail growth. Additionally, consistent nail care, including the use of strengthening nail polishes, cuticle oils, and moisturising lotions, can help manage nail fragility.
It is important to note that while Accutane can cause nail changes, these side effects are not permanent and should reverse once the medication is discontinued. However, it is always advisable to consult a healthcare professional for guidance on managing any persistent side effects.

Accutane side effects and treatment
Isotretinoin, known by the brand name Accutane, is a vitamin A derivative used to treat severe acne. It is a retinoid, and the body reacts to it similarly to how it reacts to vitamin A. Accutane has various side effects, and it is important to note that these may be different for different people.
One of the most common side effects of Accutane is dry skin, which can lead to an increased risk of scarring. The medication can also cause dryness in the eyes, resulting in irritation and sensitivity to contact lenses. This can be managed with over-the-counter eye drops, such as artificial tears. Accutane may also affect nasal passages, leading to dryness and irritation, which can cause nosebleeds. Applying petroleum jelly inside the nose can help keep it moist.
Accutane can cause muscle and joint pain, usually mild to moderate in intensity, and this side effect typically resolves after stopping the medication. However, if muscle weakness develops, it is important to inform your doctor as it may indicate serious muscle damage. Accutane may also lead to hair thinning, but this is usually temporary, and hair should grow back after discontinuing the medication.
It is important to avoid cosmetic treatments, such as hair removal (waxing), dermabrasion, or laser treatments while on Accutane and for at least six months after stopping it. Sun exposure should be minimised during and after Accutane treatment, as the skin becomes more sensitive to the sun, increasing the risk of sunburn. It is recommended to use sunscreen with an SPF of at least 15 and wear protective clothing when outdoors.
Other side effects of Accutane include mood changes, such as agitation, irritability, and depression. In some cases, it may also cause suicidal thoughts or tendencies. Accutane can impact sexual function, leading to erectile dysfunction, low sex drive, vaginal dryness, and difficulty reaching orgasm. These side effects may persist even after stopping the medication.
It is important to note that Accutane can cause serious birth defects if taken during pregnancy. Women who can become pregnant must undergo pregnancy tests before and during treatment and use effective birth control. Accutane may also interact with vitamin A, increasing the risk of side effects, so it is recommended to avoid vitamin A supplements while on this medication.
Most Accutane side effects fade within a few weeks of stopping the medication. However, it is always important to consult a doctor or pharmacist if any side effects are bothersome or persist. They can provide advice and recommend appropriate treatments or alternatives to manage the side effects.

Accutane's impact on nail structure
Accutane, also known as Isotretinoin, is a vitamin A derivative that can have several effects on the body. It is designed to treat severe acne and can be very effective due to its impact on the skin.
Isotretinoin has been found to affect the nail growth rate and thickness of the nail plate. Studies have observed statistically significant differences in nail growth rates and thickness between patients treated with isotretinoin and a control group. Isotretinoin increases the nail growth rate and gradually thins the nail plate over time. This can lead to nail fragility and onycholysis, which is the separation of the nail from the nail bed. These nail changes can impact the quality of life of patients, and dermatologists should consider these potential side effects when prescribing isotretinoin.
The exact mechanism by which isotretinoin affects the nail plate is not yet fully understood. However, it is known that vitamin A can accumulate in the body's tissues, which may contribute to its impact on nail structure. Drug-induced nail diseases can also damage the nail matrix, the hidden part of the nail unit under the cuticle, the nail bed, and the periungual tissue around the nail.
The higher the dose of isotretinoin, the more likely it is to cause nail-related side effects. These effects are usually temporary and should reverse after completing the Accutane course. To manage nail fragility during and after treatment, it is recommended to take vitamins like B vitamins, vitamin C, omega 3, and calcium to promote new nail growth that is harder and less brittle. Additionally, nail care practices such as using strengthening nail polish, cuticle oils, and moisturising lotions can help improve nail health.
While Accutane can have an impact on nail structure, it is important to note that nail changes are typically cosmetic and should not affect overall health significantly. However, it is always advisable to consult a healthcare professional for guidance on managing any side effects.

Managing nail weakness post-Accutane
Isotretinoin, the active ingredient in Accutane, has been found to cause nail fragility and thinning of the nail plate. This is due to the drug's effect on nail growth and thickness. While nail changes are typically cosmetic and not indicative of a significant health issue, it is important to manage any side effects that may impact one's quality of life. Here are some ways to manage nail weakness post-Accutane:
Manage Nail Care Routine
Consistency in nail care is essential. Keep your nails trimmed short to prevent further breakage, and use a nail file to smooth out any rough edges. Apply a cuticle oil generously, massaging it into the nail bed, the nail itself, and the end of the nail. Finish with a strengthening nail polish to reinforce the nail and prevent further damage.
Moisturise and Protect
The application of lotions or creams to the nails and nail beds can help to restore moisture and protect the nails. Eucerin Roughness Relief Cream and Burt's Bees Lemons Butter Cuticle Cream are often recommended for their moisturising and strengthening properties. Cotton gloves can also be worn under latex gloves when doing wet work, such as washing dishes, to limit exposure to water and prevent further drying.
Dietary Adjustments
Accutane can decrease levels of certain vitamins and minerals, such as B vitamins and folate, which are essential for nail growth. Consider taking supplements or increasing your dietary intake of B vitamins, vitamin C, omega-3, and calcium to promote stronger nail growth. Additionally, increasing your protein intake can help strengthen nails and support their regeneration.
Medical Advice
If nail weakness persists or becomes a source of concern, it is advisable to consult a healthcare professional. They may recommend topical treatments, such as emollients or poly-ureaurethane, or suggest ways to manage any skin infections around the nails. In some cases, minor procedures may be necessary to address specific symptoms.
