Medication After Hair Transplant: During the Recovery Period and Long-Term Optimisation
Last reviewed on 10 July 2026. We review our treatment guides every six months to keep them accurate.
A hair transplant does not finish when you leave the clinic. The first couple of weeks are when the newly placed grafts settle, and the medication you are given in that window is there to keep the area comfortable, reduce swelling and lower the risk of infection while healing gets under way.
This guide explains the medicines commonly included in a post-operative pack, the painkillers that are usually recommended and the ones to avoid in the early days, and the separate question of when hair-loss treatment such as finasteride or minoxidil might be restarted. It is general education rather than personal medical advice. Your own instructions always come from your clinic and your surgeon, and where practice can vary we have said so. Always follow the specific advice you are given, and speak to a medical professional before changing anything.
For a broad, regularly updated overview of the procedure and recovery, the NHS hair transplant page is a useful independent reference.
It helps to separate two very different things. First, the short course of medication taken in the days after surgery, which supports comfortable, uncomplicated healing. Second, the optional longer-term hair-loss treatments that some people choose to continue or restart to help maintain their overall hair. These are not the same, and the sections below deal with each in turn.
Short-term medication in the days after a hair transplant
In the first week after surgery, a short course of medication supports healing, keeps the area comfortable and lowers the risk of infection. Patients are usually sent home with a small pack to cover this period. The standard post-operative regimen is set out below. Your own pack, and the instructions that come with it, always take priority, so follow those if anything differs.
Cefalexin (Keflex) 500mg, the standard antibiotic
Cefalexin, also known by the brand name Keflex, is the standard antibiotic given after a hair transplant. Because the procedure creates many tiny openings in the scalp, a short antibiotic course is used to lower the risk of infection while the area heals.
It is taken as a 500mg tablet twice daily for six days, with one tablet in the morning and one at night before bed. As with any antibiotic, it is worth finishing the full course as instructed, even if the scalp already feels fine.
Doxycycline 100mg, the alternative for a penicillin allergy
For patients who cannot take cefalexin, in particular those with a penicillin allergy, doxycycline 100mg is used instead. Cefalexin is a cephalosporin antibiotic, not a penicillin. Cephalosporins are a closely related class, and a small proportion of people who are allergic to penicillin can also react to them, so a different antibiotic such as doxycycline is chosen to be on the safe side.
Doxycycline is taken once daily, after food, in the evening, for six days. Taking it after food helps reduce the stomach irritation it can otherwise cause. Let your clinic know about any drug allergies before surgery so the right antibiotic can be chosen for you.
Prednisolone 5mg, to reduce swelling
Prednisolone is a steroid used as a short course to reduce swelling of the forehead and around the eyes in the first few days. Some swelling is a normal part of recovery. A tight, achy and swollen scalp for a few days is one of the expected side effects of the procedure, and the steroid course is aimed at keeping this to a minimum. The grafts are your own tissue, so this is about controlling swelling rather than preventing any kind of rejection.
It is taken as 5mg tablets, five tablets once daily in the morning after food, for three days. It is important to take the course exactly as directed, including the number of tablets and the timing. If you have a condition such as diabetes, or you take other regular medication, mention this to your surgeon, as it can affect how steroids are used.
Lansoprazole 30mg, to protect the stomach
Lansoprazole is a proton pump inhibitor that reduces stomach acid. Steroid tablets can irritate the stomach in some people, and lansoprazole is included alongside the prednisolone to reduce that risk. It is taken as 30mg once daily, before the evening meal, for six days.
Pain relief, and the painkillers to avoid
Most people find any discomfort after a hair transplant is mild and short-lived. Paracetamol is the usual mainstay for pain relief. One clinic specifies paracetamol 500mg tablets up to a stated daily maximum, and some surgeons will also permit codeine if simple pain relief is not enough. Follow the dose your clinic gives you and the instructions on the packet, and do not exceed the maximum daily amount.
The more important point is what to avoid. In the early period after surgery, surgeons generally advise against anti-inflammatory painkillers, known as NSAIDs. This group includes ibuprofen (for example Nurofen) and aspirin. These medicines can make you bleed more easily than usual, which is why they are usually avoided when the grafts are fresh and the area is still healing. Advice on how long to avoid them varies: some surgeons ask patients to steer clear of ibuprofen and other anti-inflammatories for up to six weeks. Check what your own surgeon recommends.
If you already take a medicine such as aspirin or a blood thinner for a heart or circulation condition, do not stop it on your own. Tell your surgeon in advance so they can advise you, ideally alongside the doctor who prescribed it.
Restarting hair-loss treatment after a transplant
This is a separate question from the short-term recovery pack. A hair transplant moves hair to a thinning or bald area, but it does not stop the pattern of hair loss elsewhere on the scalp. For this reason, some people choose to use, or continue, a longer-term hair-loss treatment to help maintain their overall hair. These treatments are optional, and they are a personal decision to make with a medical professional. You do not need to take medication for life after a transplant.
If you were already using a hair-loss medication before your surgery, the practical question is usually when to restart it, not whether to start something new. The timing varies between surgeons. As a general range, restarting is commonly advised somewhere from around two weeks up to about six weeks after the procedure, once the area has settled. Follow your surgeon's specific instructions, because the right timing depends on how your healing is progressing.
The most commonly discussed options are set out below for information. None of this is a recommendation to take any particular medicine. What suits one person may not suit another, and each of these has benefits, limitations and possible side effects to weigh up with your clinician.
Minoxidil
Minoxidil is a widely used topical treatment for pattern hair loss. It is thought to work by prolonging the active growth phase of hair follicles, and it is available in topical and oral forms. Any benefit is generally maintained only while it is being used, and it can take several months before a difference is visible. Because it is applied to or absorbed by the scalp, the timing of restarting it after surgery is something to confirm with your surgeon.
Finasteride and dutasteride
Finasteride and dutasteride are prescription medicines that reduce levels of dihydrotestosterone (DHT), a hormone involved in the miniaturisation of hair follicles in pattern hair loss. They are taken to slow further loss rather than to help the transplant heal. Both can have side effects, and they are not suitable for everyone, so the decision to use them, and which one, is one to make with a medical professional who knows your history.
Other supportive options
Some people also consider treatments such as platelet-rich plasma (PRP) or low-level laser therapy (LLLT). The evidence for these is more limited and mixed than for the established medicines above, and they are best thought of as optional additions rather than essentials. If you are interested, discuss whether they are appropriate for you, and when, with your clinic.
Frequently asked questions
Can I take ibuprofen after a hair transplant?
Unfortunately ibuprofen and other anti-inflammatory painkillers, known as NSAIDs, are usually best avoided in the early period after surgery. Along with aspirin, they can make you bleed more easily, which is why surgeons tend to steer clear of them while the grafts are fresh. Paracetamol is the usual first choice for pain relief instead. Some surgeons ask patients to avoid ibuprofen and other anti-inflammatories for several weeks, in some cases up to six. Check the specific advice from your own surgeon before taking anything.
What painkillers can I take after a hair transplant?
Paracetamol, taken at the dose on the packet and within the daily maximum, is the usual mainstay. Some surgeons will also allow codeine if paracetamol alone is not enough. Anti-inflammatory painkillers such as ibuprofen and aspirin are generally avoided in the early period. Your clinic will tell you exactly what to use, so follow their instructions.
Which antibiotic is given after a hair transplant?
The standard antibiotic is cefalexin (brand name Keflex), usually a 500mg tablet taken twice daily for six days. For patients who cannot take cefalexin, in particular those with a penicillin allergy, doxycycline 100mg once daily is used instead. Cefalexin is a cephalosporin rather than a penicillin, but because the two classes are related, a small proportion of penicillin-allergic people can also react to it, so an alternative is chosen to be safe. Tell your clinic about any drug allergies before surgery.
Why am I given steroids and antibiotics?
The short steroid course, prednisolone, is used to reduce swelling of the forehead and around the eyes in the first few days, which is a normal part of recovery. The antibiotic, usually cefalexin, is used to lower the risk of infection, because the procedure creates many tiny openings in the scalp. Both are short courses, and it is important to take them exactly as your clinic directs.
When can I restart finasteride or minoxidil?
If you were using finasteride or minoxidil before surgery, when to restart varies between surgeons. As a general range, it is commonly somewhere from around two weeks up to about six weeks afterwards, once the area has settled. This is a decision for your surgeon based on how your healing is going, so follow their specific instructions rather than restarting on your own.
Can I keep taking my usual regular medications?
In most cases yes, but this is something to confirm with your surgeon before the day of surgery, not to decide alone. It is especially important if you take a blood thinner or aspirin for a heart or circulation condition, as these affect bleeding. Do not stop any regular medicine without medical advice. Tell your clinic about everything you take, including anything bought over the counter and any supplements, so they can advise you safely.
Do I have to take medication for the rest of my life after a transplant?
No. The medication in the post-operative pack is only a short course for the first few days. Any longer-term hair-loss treatment is optional and a personal choice to make with a medical professional. A transplant does not commit you to taking medication for life.
What should I do if I think I have an infection or a reaction to the medication?
Contact your clinic as soon as possible if you have spreading redness, increasing pain, a discharge, a fever, or any reaction you think might be caused by a medicine. For a suspected serious allergic reaction, such as swelling of the throat or difficulty breathing, seek emergency help straight away. When in doubt, it is always better to check with a medical professional.
